Very pleased to see you carefully collected and disposed of the old coolant. I am not sure of the modern products, but the early cooling conditioners, particularly Glycol based, are very palatable and totally deadly to cats. I have noticed that you have a furry friend that comes in and checks your progress on his vehicles from time to time.
You make it seem so easy, I spent a couple of hours battling with clamps and hoses that seemed glued on. Most of the green coolant is finally out, a lot on the garage floor and some still gurgling inside... But the refilling (and repeat) is for another day. Every. Single. Job. on this car takes me 3x longer than advertised!
Generally, "lifetime" = "how long the original owner has the vehicle" or "until the original warranty runs out" - so definitely get changing all those fluids every few years!
I also replaced my water pump on principle. I have also heard that the plastic vanes can disintegrate, so after 130.000 km, I thought it was time to change it. I chose the metal vane replacement pump, although the story goes that if the bearing on these go, they scrape and junk the cases, so it's six of one and a half dozen of the other. I prefer my chances with hearing the noise if the vanes touch the case with the metal pump... There is some sound missing around the 7:30 mark in case you want to add subtitles there.
I am in the process of replacing my coolant expansion tank and some rubber hoses on my 997 and would like to flush the system like you did. What did you attach your air hose to where did you attach it to? Sorry for the basic question. cheers
The way I changeover coolant type is to run the garden hose rather than air as it’s a hydraulic seal. Then I blow with air to make some space. Then fill with concentrate to the correct quantity and finally top off with water. Saves all that coolant flush procedure.
A hello from France :) thanks for all these tutorials Jeff, they are great. One question, is there a reason why you don't empty the coolant (like at 16:33) before changing the water pump?
From one plumber to another Jeff did you check the coolant flow in liters per minute. The minimum flow is 10 liters per minute at 500rpm. O have also found that Liquid Intelligence is a far superior coolant because there is no water in it. Water causes problems. There is a chap in Deniliquin that replaces the plastic impellors with stainless steel and he tests the pump and brings it to the minimum liters per minute performance. And what a difference that makes.
Do you think I can point a pressure washer nozzle into the coolant cap and fire it slowly to purge the water out of the lower hose like you did with the air compressor? I dont have an air compressor in my garage.
Jeff I think you should have done more research into water pump impellers. The reason you do not want a metal one is that when the bearing fails with the metal impeller it will destroy the engine block. Someone said they lost an engine with a plastic impeller, the only reason that can happen is when the mechanic does not clean out all the water passages and the engine will overheat. Also with an air lift tool you can get all your fluid back in the system in 10 min tops with no air issues
Instead of compressed air to evacuate coolant, I remove the thermostat and use a Milwaukee 18v cordless blower to blow it out. I prefer this method as it moves a high volume of air, but at very low, if any, pressure. But if you prefer the compressed air method, a pressure regulator connected before a radiator flush gun with the water inlet capped off makes a good adapter.
It looks like you used 100% new product when you finally filled the system! I'm pretty sure my owner's manual says to use a 50/50 coolant/water mix. Just curious that, if you mixed it, you didn't mention it, and if not, Why?
I love these lifetime products, I had a Vauxhall Astra with the sealed gearbox, never a need to change the fluid or top it up 6 months from new they had to change the fluid for a better one as the gearboxes were made in several places and they noticed lots of complaints, rather than do a recall if the customer was having problems with gear changes they changed the fluid yet I had to tell my local Vauxhall Stealer-ship what the problem was and what fluid Vauxhall recommended, they looked it up and agreed to do the change and some other bits while they had the box open, strange they didn't know what was needed yet they had everything in stock, another chap on the Vauxhall owners site booked his in the day mine was done as his local main Stealer-ship had been telling him the computer says everything is fine.
Unfortunately it already has it, but I agree it is fantastic. It is the best sounding exhaust I have heard on a 996. Not too quiet, not too loud or droney. Just right.
Loose AC bolt, typical VAG failure just like the water pump failure (plastic does cause less damage than the metal impeller!) signs of internal seizing if the AC is still blowing cold your lucky, budget for a pump Jeff, AC service with extra pag oil might extend life Great video 👍👍
@@BarnesysBuilds No, more to create a vacuum in the empty system and then draws in the fluid to avoid all of the air locks. Heidi and Fannys garage use one on their 996 turbo.
A tip for next time, when doing a job like this get the idler and tensioner pulleys and new belt, for the small cost and little extra time it just stops the need to revisit this again 👍
next time when you bleed your coolant system you can use your carlift to jackup the rear. Just put the left and right arm under the rear of the car and lift it, that is how i did it when i was working as a mechanic.
When I come across a broken spring-type hose clamp like that, I find it’s easier and faster to just take a cut-off wheel and gently cut a grove across it so the clamp bends easily at that spot.
Great job, Jeff! But don't perpetuate the IMS bearing hyperbole. Internet has made it out far far far worse then it actually is. The actual failure rate is less than 8%, and failure is often due to poor maintenance. Ofcourse 8% isn't great, but it is significantly better than people make it out to be.
You should look into one of this. It makes filling the cooling system easy plus also lets you know if there are leaks. www.summitracing.com/parts/otc-75260
Life time fluids means they will last until a few years past the warranty expiration date then the vehicle will DIE!!!! Anyone who wants to keep their vehicle from dying a premature death changes all the fluids regularly. For an average suburban driver that means between five and seven thousand miles for engine oil ten to twenty thousand miles for auto transmission fluid twenty to thirty thousand for manual transmission differential and transfer cases and fifty thousand for coolant and brake fluids every second set of pads or fifty thousand miles. These are generally good intervals for any vehicle except those that are subject to harsher conditions or have CVTs or other expensive nightmares to look after.
plastic impeller...right up there with fiber timing gears and timing belts. Why do they always try to save money on the wrong pieces? Even the Japanese are doing it now.
The compressed air trick was brilliant. Never thought about it. Thanks for the helpful tip!

Jeff Alfarrai, Alfarrai, Alfarrai please please. I'm 3months into a lockdown here and your build is one of the only things keeping me sane!
Generally, "lifetime" = "how long the original owner has the vehicle" or "until the original warranty runs out" - so definitely get changing all those fluids every few years!
Your pump looks like the Nurburgring !
was just about to say this, that water pump was the nurburgring
Hey Jeff They make a universal green coolant now that replaces red yellow and old green so it probably wasnt wrong coolant

Brilliant video mate, thanks for sharing and joined your channel as well, can now do things on my 997.1 C2S

Great timing, I need to do this as well 👍

When draining coolant, a wet vac is often the easiest way particularly if you take out the thermostat while doing it.
Try FCPEURO also.
Jeff, really great detailed video. Well Done. Quick question, would you know how much to torque the water pump bolts? Thank you

,Don’t forget to coolant flush Harry as well :-)
Haha
6:25 I dont have one of those blue taps to push the air, how do you recommend doint it? is straight in to it worse??
Do you think I can point a pressure washer nozzle into the coolant cap and fire it slowly to purge the water out of the lower hose like you did with the air compressor? I dont have an air compressor in my garage.
What is the blue plastic attachment piece you used to funnel the air in to flush out the heater core?
Hi Jeff, did you keep the reservoir cap on or off while warming the car up with water ?
At what point do you replace the vale by the fill reservoir
Good tip on not mixing coolant-regardless of colour. Mix the wrong ones and you can cause it to congeal and then you are in another world of pain.

Your note on the coolant being red, isn’t the 996 considered an older car now-a-days?
What’s different about the red one?
Different additives that don't mix.
Have you made a video on coolant change on a 986 Boxster?
No, but I have on the 996 which is basically the same.
thanks for that.
1:35 I salute you, fellow Bonds wearer

How long would it have taken to re and re the water pump only?
Jeff mate, you need to get yourself a cooling sytem 'burp funnel' gets air bubbles out.
Great vid Jeff!!
When you going to do the "Gundo" hack on the exhaust? The easiest cheapest exhaust mod you can do yourself on the 996.
+1
GUNDO GUNDO GUNDO GUNDO!
Unfortunately it already has it, but I agree it is fantastic. It is the best sounding exhaust I have heard on a 996. Not too quiet, not too loud or droney. Just right.
Oh yes! - th-cam.com/video/lFF0Wnx9-NI/w-d-xo.html
@@HomeBuiltByJeff Ok I didn't recall it already had it. I agree it sounds great on the 996.
Smart choice going metal, I lost an engine from plastic impeller blockages.
I’ll vouch for this coolant draining technique on the 996.
How much coolant did it take?
Loose AC bolt, typical VAG failure just like the water pump failure (plastic does cause less damage than the metal impeller!) signs of internal seizing if the AC is still blowing cold your lucky, budget for a pump Jeff, AC service with extra pag oil might extend life
Great video 👍👍
Ooooh coolant flush, looking forward to watching this one.
Ahh, I was hoping for some magic tricks with the flush but it just seems hard unless you're using one of those fancy vacuum systems.
Unfortunately you are spot on with the filling. A few short drives helps get air pockets out though.
@@NeilConnor I caved and bought the vacuum system. It works!
Nice work mate, im glad you have a 996! Its convinced me to have a crack as well now! cheers.
Get a cheap vacuum filler if you can first. It would have made the job much easier ;)
@@HomeBuiltByJeff I take it that creates a seal and then draws all the fluid out?
@@BarnesysBuilds No, more to create a vacuum in the empty system and then draws in the fluid to avoid all of the air locks. Heidi and Fannys garage use one on their 996 turbo.

A tip for next time, when doing a job like this get the idler and tensioner pulleys and new belt, for the small cost and little extra time it just stops the need to revisit this again 👍
I replaced the belt around 2000kms ago (and it only takes about 5 mins to swap them :D ).
next time when you bleed your coolant system you can use your carlift to jackup the rear.
Just put the left and right arm under the rear of the car and lift it, that is how i did it when i was working as a mechanic.
Good Video and nice Job a Lot of Work and you have cool trickes Love it 👍❤️👍

Now that you’re experienced, please come do mine. I’ll supply the beer.
Great job, Jeff!

Ofcourse 8% isn't great, but it is significantly better than people make it out to be.
Thanks Jeff for Covid virus vid' on Archie could you check air/oil separator?
That may be a future video I think
Thanks mate
Great video Jeff. Does not look as easy as working on Harry....
Harry definitely has less water pump issues ;)
Pretty sure Porsche coolant is yellow/green?
How much of the 20lt of coolant went in in the end?
It took a few short drives to get out all the air pockets, but the whole 20 went in eventually.
Incidentally my 997's water pump failed a while ago. No engine damage, but still unpleasant.
Hi Jeff, do something with this rusty exhausts...
It is not rusty, and it sounds fantastic. Nothing to do.
@@HomeBuiltByJeff little bit polishing is always good 🤟 best regards to Sydney 🤟
Yep they are ferritic stainless so they might look a bit grubby but they aren't going to get any worse.
@@colinartus1897 but it could be polished :-)
Excellent Work A+++

Does anyone else think the water pump outline kinda looks like the Nordschleife?
I was going to say the same thing.
Subliminal messaging :D
This pump drawing looks like Nurburgring? Coincidence? I think not 😉
Only one Alfarrari video a week? 😔
