1979 Leocraft motorhome / 454 chevy / power steering pump brake booster issue

On the freeway it through the belts(3 belts not serpentine). I was able to limp it home using one belt from the balancer to water pump to alternator. The power steering/brake booster and air pump were left off. Now that the belts have all been replaced there is a loud screaming sound - belts are tight. I think its coming from the power steering/brake booster. Any thoughts ?

I would suspect the water pump, power steering noises are usually grinding sounds. Also if the belts shredded check behind ALL the pulleys for the reinforcing strands from the belts. Basing this on general car problems , not any actual Chevy.

The chirp is from scale or a glaze on one of the pulleys. If not black or shiney in color clean it with brake cleaner and spray some belt dressing on the pulleys

SOURCE: Power steering went out on

Have you checked your tie rods? Possibility one is either bent or broken, I've seen it before on TB's. That pulley shaft is a common problem to break, especially when cold out. PS pumps/pulley shafts and tie rods will snap if doing donuts in the snow with the steering wheel cranked, or off-roading. The PS is completely mechanical, no fuses or relays.

2003 Jeep Grand Cherokee. What is wrong with my steering wheel?

That is strange because they are unrelated.

The power steering works using a pump that has a pulley and is turned by the Serpentine belt. Where you put the fluid, did it look like this?

https://www.google.com/search?q=2003+jeep+grand+cherokee+power+steering+pump

The Brake Master Cylinder has a similar reservoir and also has a brake booster that uses vacuum power from the engine to give you a mechanical advantage. Both are shown here

V-belt routing for a Chev 454 (7.5l) engine

This is the routing diagram for a 454 engine using v-belts only, not a serpentine belt.
The following abbreviations are used :
  • C - Crankshaft
  • S - Smog pump (A.I.R.) system
  • W/P - Water Pump
  • Alt - Alternator / Generator
  • A/C - Airconditioner
  • P/S - Power steering(In some installations also includes the brake booster pump)
This particular setup is most prevalent in motorhomes. Refer to the diagram.
Diagram 1 is for the first groove on the crank(closest to the block), and utilizes the 1st groove on the power steering.(belt no : 15415)
Diagram 2 is for the 2nd crank groove and utilises the 1st groove on the water pump pulley, the A/C pulley and the 2nd groove on the P/S pulley.(belt no 15590)
Diagram 3 is for the 3rd groove on the crank

http://c.fixya.net/fixya20/uploads/images/724c369.jpg
If your motorhome uses a serpentine belt it replaces the belt in track number 3. (serpentine belt no : 6K560)
The upper smog pump(not shown in diagrams) is powered from the powersteering (Hydraboost) pulley (V-belt no : 15450)

1979 Leocraft Motorhome. With a 454. When the engine gets hot it stops receiving fuel. Any ideas? Changed fuel pump and collapsed fuel line section.

Sounds like vapor lock. Vapor lock happens when the fuel in the lines gets way to hot and boils/vaporizes and causes stalling . Have the fuel lines wrapped in an insulated wrap or relocate them away from heat sources. Sometimes winter grade gasoline will cause this also.

1978 chev motorhome brakes are hard to push down to stop

If they are standard power brakes, check the vacuum booster. The diaphragm may be broken. If it holds a vacuum it's OK. If the brakes run through the power steering pump, make sure the belt is tight and the steering is smooth.

Power steering leak

Lingo is o.k., but I think you may be confusing power steering with power brakes. Power steering has no master cylinder (brakes do) and no power booster (brakes do). The power steering pump is mounted on the front of engine and run by the fan belt or the serpentine belt. The p/s hoses are 2- a pressure line and a return line, and run from the pump to the steering box or to the rack and pinion steering gear.
It just sounds like you have a brake fluid leak at the master cylinder. If it is, you need a new or rebuilt brake master cylinder.
Good luck. Post back for more.

I need to top up the power stering fluid and need to know what tipe to use 1988 chevy silverado C3500 454 The power steering looks like it is incorperated into the brake booster

power steering is at the front of the engine and runs on the belt. The reservoir cap looks like this:
73b4b95.jpg To top off steering fluid, use standard steering fluid.

The reservoir in front of the brake booster is the brake master cylinder reservoir. To refill, use standard brake fluid. If it the truck is using brake fluid, check for leaks at the back of the master cylinder and at all wheels.

Please let us know if you have more questions.

Lost power steering and brakes on 96 Astro

Hello altgraph1: My name is Roger and I can help. The power steering and the brakes are directly connected. If the power steering pump fails you will also loose the brake assist. This vehicle does not have a vacuum booster you have a hydro-boost brake system. This unit uses the power steering pressure to assist the stopping of the vehicle. You will need special tools to determine if the power steering pump failed or if the hydro-boost system failed. Most likely the power steering pump failed. How ever to be sure it should be tested first. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger
