79 Cadillac Phaeton. In Western Saddle Firemist. Interior is Antique Saddle. That's a 425. The "reflectors" in the rear are actual lights, side markers just like the front side ones. The cornering lights light when when you have all lights on in conjunction with the turn signal. The blower motor turns on once the engine temp has reached its temperature. It has what is called a heater turn on switch just behind the alternator, single wire. the rear spark plug is easy lol. I start off with that to get it out of the way. I have a 78 Coupe deVille. If you need any help with yours lmk. I'll be glad to assist.
That car brings back a lot of memories, especially after hearing the chime going off as you were starting it. My dad had a 79 Coupe Deville, which I learned to drive on at the age of 15 many years ago. I used to go out joyriding in it with my brother. Long before they had steering wheel and gear shift locks, we'd put it in neutral and push it out of the garage and down the driveway before starting it when we hit the street. I bought an 84 Coupe after my dad died in 2001 as a tribute to him, but it had the dreadful 4.1 L. I didn't keep it for long. Anyway, keep up the good work!
The way to tell the difference between the 425 and 472 is that all 425 for the 3 year production have corporate blue valve covers and the 425 on the left valve cover is flat on top until you get to the last 4 inches in where the top slopes down
Those Phaeton variants are really cool. The extra bumper fin pieces you have in the back seat are actually for newer models and appear to fit the 1980-84 Devilles and 1980-1992 Fleetwood Broughams/Broughams (though the same car, Cadillac removed the “Fleetwood” name between 1987 and 1992 so they were just called “Brougham” as to avoid confusion with the FWD Fleetwoods of the late 80s, which were very different from the RWD models).
Love your videos! Please make more cold and first starts and show us what you do with the gas pedal when doing it. Love seeing that in carbureted cold starts
I've been working at a body shop for a bit now and extra tips I learned was if you're painting the door, it's better to take off the mirror and belt molding (the trim at the bottom of the window) for a better paint job in the end. The mirror can get in the way, and if you're unlucky, the clear coat could stick in that gap between the door and the belt molding.
The windshield wipers are the original Trico windshield wiper made from stainles steel. You can change only the rubber lip. This a little bit tricky work, however better than ugly new black windshield wipers. I see the black cable for the boot electromagnet hanging down on trunk lid. It must be fixed on the left hinge with a hose fore protect and then with a plug together made with the cable what comes from the front…..thre is somewhere one. Then the boot release „will function only with ignition on“. The engine for the hook is on the right in the boot behind the disguising. There is still a fuse. Look whether power there it comes and then look whether the fuse is okay. If then the plug on the switch is something would have to happen. The Blackcable from the Switch Must be on Ground. It’s not got the Trunk Lid Shot down Servo dosent work. it Can Destroy the the Switch. Good luck
Engine runs good. If it is not shaking its good. New exhaust with a quite muffler like " Quiet-Flow SS # 22317 from Walker“ then sounds like a Cadillac. Headlamp need 8 new headlamp adjuster and 4 springs…..then the lamps you can adjust and looks better…one new sealed beam…one better headlamp door…..
Omg can I send you a picture of my 1979 Sadan de ville I don't have the car no more but it was and still is my favorite vehicle. I got it when i was in my early twenties It was all green with a white top and green in the inside hey anyways let kno if you want to sell or maybe give it away
You’re more than welcome to send some pictures of it. I’ve got my instagram linked in the profile, if that don’t work, I can give you the email. Thanks!
Hello Nice to see somebody work on Cadillac..Im Cadillac driver fore 30 years 1977 Fleetwood Brougham de Elegance. The problems with bad start I think not batterie and no starter. Your engine have bad ground. Bolt on a thick wire from batterie minus direct to Bolt on upper generator holder…bracket. then you wonder how fast starter will turn the Engine. Inigtion make it also better. Bad ground bad spark. Original is a twisted copper groud tape from frame to transmission. Meby sombody forget on engine shwab. The engine block is the same 425,472,500. All oilpan and valve cover fit all engine. The exhaust manifold is 425 different to 472 and 500. 425 have the reticted Manifold. That’s bring less Power. 472 and 500 better! ….a you have the space problen with the bolt first cylinder and upper control arm. this normal. Cut of a space of control arm….than will it work. I have had 12 year a 500 in….self problem. The generator and starter you can rebuild fore smal money. All parts are give seperat.
That's probably the original 425. You can tell because it looks too good to have been swapped out and plus, if it really was a 500 they would have kept it. I don't understand this thing about a "swapped out engine" being a selling point.
Yo great video my guy tho ur audio is a bit quiet on the talking side and very loud on the noise side cuz I can't hear you unless I turn it up yk I'm just saying that cuz bad audio drives a lot of ppl away
Thanks for the feedback, I definitely have some learning to do on the editing and filming side. I'll try to get the audio better on the next one though.
vice grip garage knockoff huh.. nice car though, i had an 84 with a ht 4100 in the same firemist color.. currently have a 76 coupe with a 500 that came from the factory with customizations from encore
even if it "runs" ... the brakes are shot - shocks are shot - tires are shot - engine manifold gaskets are shot - exhaust manifold gaskets are shot .... belts / hoses / seals are also shot ... it's going to cost THOUSANDS of dollars to fix !!
Hey cool car I love caddilacs but if it shakes at a 100 then don't go that fast and I don't know why someone needs to drive that fast and becareful these classics cars are not made to be beaten up like trucks ...
Here’s the link for the battery terminal things I talked about in the video. www.ebay.com/itm/224378718753?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=B6Qd1yJfRKG&sssrc=4429486&ssuid=V0l3okqQT3u&var=&widget_ver=artemis&media=COPY
Go ahead and replace the whole exhaust system and get a vintage tag they're exempt from inspection and never run ethanol gasoline in that car will destroy the fuel pump. It's not worth a few cents a gallon you save your pump will dry out the diaphragm and then all of a sudden the car won't start and it's cuz the diaphragm is torn. And the fuel sender will rot off and then you won't know how much gas you got. Find non-ethanol gas that they put in boats. 87 octane is fine and then you're not going to have fuel system problems trust me I know from experience. And get a brand new fuel pump to keep in the truck with a half inch wrench so when it does happen because that one is old then you got a new one to replace it but never run ethanol gasoline in that car
EBay and RockAuto. The hubcap logs are several different color keys that fit those but you might be able to hammer a 16-point socket onto them and turn them, they only turn about an inch to unhook from inside the steel wheel that's all they are hooks. Once you get the Caps off you can actually remove the locks, there are different hubcaps that are a lot lighter I use the vented ones in summer and the non-vented hubcaps in Winter on my Cadillacs.
Get the dual post battery where you have the top posts and the side posts because you'll be connecting your blower motor wire to that top positive post and having that light switch under the dash to turn the blower motor on and off with an inline 40 amp fuse. It's an l78 battery I think
The fuel filter is a 1-in wrench you'll want to cut the pipe just after that because it's not going to unscrew for you. Then unscrew and change the fuel filter screw it back in and then join the two pipes together with a rubber ethanol resistant piece of hose and two clamps. It makes changing that filter easy if the car starts to sputter going up a hill after driving it a while it's time to change the filter again that debris in the tank is clogged it up. Do not add an inline filter and delete the one in the carburetor that thing you can only use the factory filter.
And run 20w50 Castrol non-synthetic with some Lucas in it. Do not run synthetic lightweight engine oil in that car you will Spring leaks everywhere 20w50 and Lucas additive and you'll have no problems.
To empty out the fuel tank disconnect the two pipes from the fuel pump and pump air into the tank using a shock absorber bushing and a nozzle from your air compressor and pump all the fuel down the pipes out of the car when you're done to take note the metal pipe just in front of the frame open the left rear door and then look straight down under there's a corner Bend in that pipe and it's prone to rust in that corner and get a hole in it and then your fuel won't make it to the pump and you won't notice it and you'll get stranded so always check for a wet spot on that part of the fuel line. You want to lower the fuel tank and replace those three rubber pipes. The Junction the fuel lines to the tank. If you're real industrious you'll pull the tank in line it with red coat. And refit the tank. Hopefully that car has rear drum brakes the disc brakes in the rear are always a problem and gave you a low brake pedal. The Fleetwood version of that car had rear disc brakes and aluminum Hood. It is possible to buy the aluminum Hood paint it the same color as your car and replace it and always oil those hood hinges if it's stiff to close stop and get some spray oil and oil every section of the linkages of those hinges. That's crucial so that they won't Bend and in the hood doesn't close right. There's a whole lot more things I've done to these cars to make them like new I drive a 78 Coupe DeVille as my driver car
Unless you have paperwork in the glove box about the engine, I seriously doubt that motor was pulled out. It was an h e i, distributor still there, and those tail fins in the floorboard those are for an 80s Cadillac they won't fit that bumper. The rear plastic panels need to be replaced with plastic or fiberglass they come in two different kinds. For 1977-79 Coupe sedan DeVilles or fleetwoods. The air conditioner programmer always shuts down the blower motor so I run a devoted wire from the blower motor to a light switch under the dashboard to turn the blower on and off. Yes the heat even the air May blow out the defroster vents but at least you're able to get the blower to work the programmer is hard to get a rebuilt one and are spendy. How to replace the brake hoses on that car, the belts, the shocks, the headlight adjusters, get a set of H4 H1 halogen conversion headlight replacements. You do have to change the arrangement of the three wires on the low high beam to use the H4 bulb but it's well worth it cuz you can see it night. You simply remove the three wires from the plastic plug change the arrangement until they function properly and then put them back in the plastic plug with a small Spike tool and then you're able to use H4 halogen bulbs. There's a wire under the floorboard next to the floor dimmer switch that sometimes gives a problem, and it suddenly you'll lose your headlights and that's what it is and has to be repaired. I like getting the 1977 front turn indicator lenses that are white not yellow and then use the Switchback bulbs 1156 1157 that are yellow white. You can actually see where you're going with the white parking lights on and when you put the blinker on they changed to Yellow like the modern cars do. A simple bulb Swap and a lens swap. You get the lenses from the salvage yard say you want the clear 1977 version. Why I know these things I have eight Cadillacs. 1976 to 1979 I won't buy one after 1980 because of the aluminum engines. There's a water neck that's made out of cast iron from Four Seasons you can replace the water neck that's on the engine block that steel that rusts and begins to leak with the cast iron version. And I changed the thermostat to a 160. The fan clutch probably needs to be replaced on that car because it's so old if it begins to overheat.
You're shaking in the front end is a bad tire. It probably has a bulb on it separation in the tread I always know when I get a really bad shake that one of the tires has gotten air between the belts and is about to blow . don't drive too far on that change the front tire change all the tires. And definitely get rid of the catalytic converter. It should be already gone
It's got Eight Track on the stereo! That bell sound when you turn the key is beautiful!
I wish I had some Eight Tracks to see if it worked!

Thanks for the info! I’ve definitely had to do a lot of reading and research on it since I’ve got it.
Nice ride keep it coming sounds good a little tune up fresh gas u in there nice 👀 🍿 watching an learning 💪
Thanks! This car is turning out to be a learning experience for me too.
I had a '78. Loved watching you work on this car.
Thanks 👍
Very nice! Would be cool to see a follow up video cleaning and polishing the paint too. She’s a beaut!
Thanks! I’m planning definitely planning on trying to polish on the paint and see what it looks like!
The interior could use some love but the exterior is in amazing condition. Good luck with the mechanicals, it's a fine old car worth saving.
Thanks! Definitely wanna fix up the interior some more
Man ol son your commentary throughout this video is stellar, truly funny
Thank you!
You put out some good content. Back in '79 that was a small Cady.
Thanks!
That car brings back a lot of memories, especially after hearing the chime going off as you were starting it.

Thank you! Love hearing the stories like this!
A 1979 would have had a Steering Wheel Lock
Good video bro 👍🏻 if you make some more I'll be watching. Old Cadillacs or square bodies will get you lots of views and subscribers.
Thank you!
CB? That's approved.
Very cool.
Edit: good job on the video.
Thank you!
You are doing an absolutely fantastic job sir very educational and family friendly definitely subscribing which Is well deserved
Thank you very much!
Great video, thanks! Engine is 472 or 500 but horsepower could be anything depending on year.
Thanks! I definitely need to run the numbers and find out more on the engine
Actually 79 came with 425 engine lots of torque you have no problems with this big block 💪
The way to tell the difference between the 425 and 472 is that all 425 for the 3 year production have corporate blue valve covers and the 425 on the left valve cover is flat on top until you get to the last 4 inches in where the top slopes down
Thank you!
Those Phaeton variants are really cool. The extra bumper fin pieces you have in the back seat are actually for newer models and appear to fit the 1980-84 Devilles and 1980-1992 Fleetwood Broughams/Broughams (though the same car, Cadillac removed the “Fleetwood” name between 1987 and 1992 so they were just called “Brougham” as to avoid confusion with the FWD Fleetwoods of the late 80s, which were very different from the RWD models).
Good to know! I really wasn’t for sure how much I would like the Pheaton package at first, but it’s really grown on me and I love driving the car!
I’m such a big fan 🙌
❤❤❤ you got my car lol 😂 same color and all just a year apart I also did a full restoration and is still currently going thanks for the help and tips
That’s awesome! You’re welcome!
Love your videos! Please make more cold and first starts and show us what you do with the gas pedal when doing it. Love seeing that in carbureted cold starts
Hi! I got a 79 coupe deville. Of its stock it has a 425 engine. Last of the big blocks. Pulling about 180 to 200 hp.
Love the look of the coupes!
That hood would make a great tonneau cover for a long bed pickup truck .
😂
Vice Grip Garage -esque
Awesome Cady! cool video!
Thanks!
The extra battery tray on the other side is most likely for the diesel version. My dad had a 1981 Cadillac diesel and it had 2 batteries.
That’s kinda what I was thinking!
my favorite car
Looks and sounds like the 500 8.2 liter that's in my 76 Cadillac Fleetwood Brougham lol. Great cars nevertheless ❤
Definitely need to run the numbers to see exactly what this one is.
Hey go ahead and replace exhaust system 😊 thanks a lot
That's the plan!
This is the coolest video I’ve ever seen
I've been working at a body shop for a bit now and extra tips I learned was if you're painting the door, it's better to take off the mirror and belt molding (the trim at the bottom of the window) for a better paint job in the end.

Thank you for the info!
Awesome video man🤙
Thanks man!
Awesome Vid! More more more!
More to come!
Love it ...I think it's awesome for as old as it is..Great video new subscriber..
Thanks for the sub and welcome!
Love these type of behemoth cars. Good luck with channel I’m your 15th sub can’t wait to watch you grow! And feature the chickens!! 🤘🏼
Thanks for the support! There's just something about these old land yachts that I love. You got it on the chickens.
@ 12:30 I thought them chickens were the car trying to crank over 😂 he wanted camera time
Haha! They definitely get loud and want attention😂
The windshield wipers are the original Trico windshield wiper made from stainles steel. You can change only the rubber lip. This a little bit tricky work, however better than ugly new black windshield wipers. I see the black cable for the boot electromagnet hanging down on trunk lid. It must be fixed on the left hinge with a hose fore protect and then with a plug together made with the cable what comes from the front…..thre is somewhere one.
Then the boot release „will function only with ignition on“. The engine for the hook is on the right in the boot behind the disguising. There is still a fuse. Look whether power there it comes and then look whether the fuse is okay. If then the plug on the switch is something would have to happen. The Blackcable from the Switch Must be on Ground. It’s not got the Trunk Lid Shot down Servo dosent work. it Can Destroy the the Switch. Good luck
You should do a vid on fixing the exhaust leak
It’s already in the works lol
Engine runs good. If it is not shaking its good. New exhaust with a quite muffler like " Quiet-Flow SS # 22317 from Walker“ then sounds like a Cadillac. Headlamp need 8 new headlamp adjuster and 4 springs…..then the lamps you can adjust and looks better…one new sealed beam…one better headlamp door…..
the engine number is rear side near oil pressure switch
Thank you for all the info! I’m definitely still learning on this thing. Hopefully the exhaust will be fixed in the next month or so.
Omg can I send you a picture of my 1979 Sadan de ville I don't have the car no more but it was and still is my favorite vehicle. I got it when i was in my early twenties It was all green with a white top and green in the inside hey anyways let kno if you want to sell or maybe give it away
You’re more than welcome to send some pictures of it. I’ve got my instagram linked in the profile, if that don’t work, I can give you the email. Thanks!
New sub. Awesome vid bro. Looking forward to seeing more of your content
Thanks man!
Hello
Nice to see somebody work on Cadillac..Im Cadillac driver fore 30 years 1977 Fleetwood Brougham de Elegance.
The problems with bad start I think not batterie and no starter. Your engine have bad ground. Bolt on a thick wire from batterie minus direct to Bolt on upper generator holder…bracket. then you wonder how fast starter will turn the Engine. Inigtion make it also better. Bad ground bad spark. Original is a twisted copper groud tape from frame to transmission. Meby sombody forget on engine shwab.
The engine block is the same 425,472,500. All oilpan and valve cover fit all engine. The exhaust manifold is 425 different to 472 and 500. 425 have the reticted Manifold. That’s bring less Power. 472 and 500 better! ….a you have the space problen with the bolt first cylinder and upper control arm. this normal. Cut of a space of control arm….than will it work. I have had 12 year a 500 in….self problem.
The generator and starter you can rebuild fore smal money. All parts are give seperat.
Great video!
Nice! It'll pass everything except a gas station!
Haha! You ain’t wrong!
Mate you should read for children’s audio books , very mellow voice😎👍
Thank you! Never read for any books, but I did used to sing.
Would love to see you do a cold start on the first vehicle without any choke. Will it start if you crank it over a few times?
We’ll have to see if it will
That's probably the original 425. You can tell because it looks too good to have been swapped out and plus, if it really was a 500 they would have kept it. I don't understand this thing about a "swapped out engine" being a selling point.
Hello how are you doing? I would love to own this Cadillac! Are you going to sale this Cadillac?
A 425 would be the same size block as the 472 or 500, even the 368 was the same size
Good to know! Thank you!
I'll buy it
I don't know if I wanna sell it yet. But for the right amount it could be for sale.
Do repair videos on this car
Those th400 like to leak from seal change fluid that transmission is strong
Will do, thank you!
There are little plastic adjusters that usually break and make the headlights go cross-eyed like that.
Thanks, I've gotta get some and fix these things, they're horrible going down the road at night
The trunk button wont work unless you have the key in the on position.
Love the car wish I had a car like that
Yo great video my guy tho ur audio is a bit quiet on the talking side and very loud on the noise side cuz I can't hear you unless I turn it up yk I'm just saying that cuz bad audio drives a lot of ppl away
Thanks for the feedback, I definitely have some learning to do on the editing and filming side. I'll try to get the audio better on the next one though.
vice grip garage knockoff huh.. nice car though, i had an 84 with a ht 4100 in the same firemist color.. currently have a 76 coupe with a 500 that came from the factory with customizations from encore
Not at all trying to be anybody’s knockoff. Just documenting what I’m doing to a car I like that I was able to find at a reasonable price.
even if it "runs" ... the brakes are shot - shocks are shot - tires are shot - engine manifold gaskets are shot - exhaust manifold gaskets are shot .... belts / hoses / seals are also shot ... it's going to cost THOUSANDS of dollars to fix !!
🎉
She's a 472. 7.7 litre.
Hey cool car I love caddilacs but if it shakes at a 100 then don't go that fast and I don't know why someone needs to drive that fast and becareful these classics cars are not made to be beaten up like trucks ...
I’ll keep it under 100!
@Youngsrepairshop thank you sir and I hope to see more videos of your vehicles and this caddy too ...
@@andycomella1726 they’ll definitely be more coming
How do you get it to pass inspection
Luckily no inspection in NC for anything 30 years old or older. And if it’s newer it’s only a safety inspection where I live
What do you want for it I have the coupe
I don’t know yet, I’m really enjoying it so far. Can always shoot me an offer though.
Here’s the link for the battery terminal things I talked about in the video.
www.ebay.com/itm/224378718753?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=B6Qd1yJfRKG&sssrc=4429486&ssuid=V0l3okqQT3u&var=&widget_ver=artemis&media=COPY

Thank you very much for all the info! I’ll definitely reach out if I run into anything.
Get the dual post battery where you have the top posts and the side posts because you'll be connecting your blower motor wire to that top positive post and having that light switch under the dash to turn the blower motor on and off with an inline 40 amp fuse. It's an l78 battery I think
The fuel filter is a 1-in wrench you'll want to cut the pipe just after that because it's not going to unscrew for you. Then unscrew and change the fuel filter screw it back in and then join the two pipes together with a rubber ethanol resistant piece of hose and two clamps.

Yes the heat even the air May blow out the defroster vents but at least you're able to get the blower to work the programmer is hard to get a rebuilt one and are spendy.

You get the lenses from the salvage yard say you want the clear 1977 version. Why I know these things I have eight Cadillacs. 1976 to 1979 I won't buy one after 1980 because of the aluminum engines. There's a water neck that's made out of cast iron from Four Seasons you can replace the water neck that's on the engine block that steel that rusts and begins to leak with the cast iron version. And I changed the thermostat to a 160. The fan clutch probably needs to be replaced on that car because it's so old if it begins to overheat.
You're shaking in the front end is a bad tire. It probably has a bulb on it separation in the tread I always know when I get a really bad shake that one of the tires has gotten air between the belts and is about to blow . don't drive too far on that change the front tire change all the tires. And definitely get rid of the catalytic converter. It should be already gone
