- Thought i would spend my saturday tinkering with the power steering belts to see if i could get the squealing to stop and to figure out why i'm getting no power from it.
Thanks for watching.

As always, you're videos are my 'go to' channel for things like this. My power steering was chattering for a while, last night it started leaking fluid (running fluid really) now starts the job of troubleshooting and likely more to come... as always seems to be the case with our P30 motorhomes! Never a dull moment!! Be safe Nathan!

Not sure about yours but that pump you were working on is the ac pump !
Power steering is below that and much harder to get to !
Looks to me like you tightened your ac pump belt. There are three separate belts . Alternator/fan that runs to your crank pulley. Then your power steering belt , next is your AC belt .
The diesel sounds like timing with the hard start , but if you start it up for a few and don’t kick down the choke or high idle , it’s going to diesel
Omg this just happened to me. It s making that noise when i turn it to the end ,left and right.
NOW I CAN'T EVEN TURN IT. I WILL TRY TO TIGHTEN BELTS AND COME BACK to see what progress you made.
The dieseling is a timing plus the idle speed adjustment on the carb. I had to replace my carb as the previous owner attempted to adjust the idle mixture setting. In doing so he ran the idle mixture jet screws in HARD to the point of cracking the base plate of the carb. This resulted in no matter the setting the idle could never be adjusted lower than 1800 rpm. and would diesel on shut down.
As to the hard start after running that is "heat soaking" this is a common problem with ANY of the GM's or Chevy's with the Big Block V8 engines. What happens is because the starter is so close to the exhaust manifold, about 1 1/2" away, the copper windings in the starter increase in resistance when they get hot and must wait sometimes for 15 -30 minutes to cool enough for proper operation. Also the main power cable from the battery suffers "heat soaking" too.
Correction is to add a starter shield, also the power cable to the starter should be 4 guage and heat shielded with in a 1" tube as the cable runs under the manifold to the starter. There is also a heat deflector shield for the right side of the engine that blows airs down the right side of the engine to assist in removing heat.
Hope this helps.
Because it was a problem with hot start I think you are right about starter getting heated. When it bogs on cold start I would check timing...could be too advanced.
Or even a flat spot in cam, or a cracked valve, had similar issues, allowed manifold vapors to seep past the week cylinders on mine, messed with timing for a week before doing leak down and compression check...
i have one steering is lose found steering box is bad i put new air bags on front and tie rods and upper and lower ball joints . and tune up and distributor. runs like a champ and rides like a dream
I have the same problem on my '86 Fleetwood PaceArrow it is on a P30 chassis with a 454 or 7.4L V8 engine. Along with the pump running the power steering it also runs the power assist for the power brake system. You will also notice soft or spongy brakes where you need to pump a time or two to get them to fully work.
Any update on your fix I replaced pump Still have issue Exact issue you mentioned. Any help would be appreciated.
@@dwightmcammond5597 Same here!
@@chrisbaker4475 I had the same problem. Mine would not turn at all. It ended up being a bad hydroboost. It was actually pretty easy to do. Once the shield is removed there is plenty of room to do the job.
Remove the left wheel and the shield that is mounted to the frame. Once the shield was removed I removed the lines and hoses to both the hydroboost and master brake. Remove the master brake cylinder from the hydroboost. Remove the bolts that support the hydroboost and remove the hydroboost bracket, the hydroboost.
@@lisah6451 I very much appreciate the reply! Just today I brought it to a local RV repair shop, I needed a NYS inspection as well anyway. I really don't have the ability to do this kind of engine work. I'm a plumber/electrician/carpenter.
Sounds like he's tiring box is gone . It's not a bad fix just make sure your wheels are seat along with your steering wheel. The hard start is defamatory a tuneup and timing issue but I would also save up and convert it to fuel injection wither one of the numerous kits online from holly and such company's. I did my rev and it started the first time every time and my gas Mileage went way up and payed for itself in 2 years
I love old motorhome! Got character!
MAY WANT TO GET SOME AIR IN THOSE TIRES AND MOVE THE COACH SO THOSE TIRES ARENT SITTING IN THE SAME SPOT. TIRES THAT ARE LOW ARE MUCH HARDER TO TURN. A GOOD TUNE UP PLUGS PLUG WIRES AIR FILTER AND SOME GOOD HIGH TEST GAS. DID YOU ADD ANY FUEL STABILIZER WHEN YOU PARKED IT?
Nathan, were you able to get the power steering / hydro-boost pump belt tightened? How did you do it? I was thinking from below by removing the bottom section of the fan shroud which gives access to the lower front of the engine. Any thoughts?
Great video.. Keep up the great work
My girlfriend and i fulltime RV, we just upgraded from a small 78 dodge minnie Winnie to a 33ft coronado (p30 chassis) ive only driven it once due to the power steering AND brakes not working properly. I believe its going to be the hydroboost in mine, the guy we got it from saod it jad a new power steering pump installed at one point but didnt fix the issue, any idea how hard it is to replace the hydroboost in a class a? I cant even see the thing from in the hood
I just got done replacing my hydroboost. It was actually very easy. Remove the left wheel then remove the shield. Once you have the shield removed it is easy to get to the hydroboost. You have to remove the master brake cylinder off with the hydroboost.
I actually found it easier to leave the hydroboost mounted to the bracket and remove the hydroboost, the bracket and the master brake all in one piece.
Where can you find the location to out power steering fluid in?
I have an 87 Winn that looks exactly as your RV. Stupid question - Where do you put in the fluid for brakes and steering? Just bought RV and trying to do some maintenance. Any advice would be great. Thank you!!
The brake fluid goes in the brake reservoir which is located in the drivers wheel-well behind a shield that has a square hole cut in it so you can access it. I have also read some of these motorhomes come with a small hatch on the floor near the driver's seat so you can get to it easier, mine unfortunately does not making it a little difficult to get to but you can still do it.
The power steering reservoir is under the hood, it is black and cylindrical and has a little cap on the top
I thought I found for the steering but it only states to use proper fluids and not to over fill.Didn't want to risk putting in the wrong stuff.
You are a blessing! Looks like the tire and I are going to become very close friends tomorrow. haha
Thank you so much!!
Class A Living I'll be keeping you around. I just know I'll find something else that will boggle me. lol
Thank you again! ~ Blessings to you and your loved ones!
Love reading these. Great Channel. GOD Bless
You have to check the fluid levels as well ( you probably already have) power steering uses fluid to assist in ease of turning(if you will). check your hoses too ,, a supply line or pressure hose is about 20 bucks. the return line is cheap as well, one could be split or leaking.
Use a vacuum pump tester to check and apply vacuum to rid air pockets in pump via reservoir. Air in steering pump causes cavitation of centrifical force causing sharp whining sounds.
Did you ever figure out what the issue was?
how to bleed power steering & parking brake on 1994 Winnebago class a RV motorhome
Hi bro, you may want to check your tire pressure on the left side.
+Santos Vega Thanks! It does look pretty low im going to check it as soon as i get a gauge :)
@@ClassALiving The belt may need more tightening since it might be slipping silently at the new tension. Maybe see if it gets hot. It may be designed to be stiff when sitting still on dry pavement, which is the hardest condition, and an ageing pump might want a thick fluid additive, especially if it behaves better when cold. Lucas makes them.
Didn’t check power steering fluid. Why not? Cavitation in power steering pump is caused by air getting in. Replace seals at pitman arm if pump won’t hold steering fluid. Check pully for excess play if so replace pump. Hard start after warmed check ground connection. Make sure both battery connections are corrosion free.
Thanks for Video
Mine is making that noise and also the breaks. Any ideas. Please 🙏🏻🙏🏻🙏🏻
My issue fixed itself when I took the steering centering springs off, seems as though they were too much for my power steering to handle when turning.. tightening the belts may have helped too
@@ClassALiving i guess my power steering and brakes are the same system and when i turn left or right pr apply pressure to the brakes it makes the same noise. Mine is currently stuck in park.
Mines a 454 and it tires to run after being turned off but I have to find out how the belts go
Timing advanced to far, hard starts and dieseling.
Cant diagnose the power steering with the info available.
Hey people. I just finished troubleshooting the same problem. I found out there was a belt completely missing
I think my ‘87 Itasca Sunflyer has the same issue. I cracked ‘er open today to tighten the power steering pump and there’s no belt attached, but not sure if it’s by design or not. I mean i solved my “whirling” sound as in this video and pump is working fine.
Mine don't have a hard time rea starting but it dose like to keep running after key is pull for like 7 seconds
Check powersteering pump psi should be 1400psi if 1200psi replace pump
You have air in the lines. You need to bleed them.
Radiator hose is routed incorrectly.
new pump
Question ?
