Generally, there are two levels on a dipstick. With the car level and the engine hot, the fluid should be up to the "hot" mark. With the car level and cold, it should be to the cold mark.
To check the power steering fluid on your 1991 Caprice remove the cap on the power steering pump fluid reservoir and check the level on the fluid level indicator. If the fluid is warm(about 170 degrees)the fluid level should be at the "Full Hot" mark. If the fluid is cool(about 70 degrees) the fluid level should be at the "Full Cold" mark.Always use the correct power steering fluid to avoid damage to the hoses and seals which will result in fluid leaks. It should be noted that the reservoir (pardon my spelling) is located under the alternator (On my '91 with the 305, that is) - So you can't do it while the car is running.....Kenny
1. Low steering fluid level. 2. Incorrect software version in steering ECU. 3. Failed steering ECU. Some Early Vectras (of the Vectra "C" model) had a fluid level switch in the fluid bottle. This switch is well known for giving false "low fluid" warning messages, and was deleted from later cars. There is a software update available from Vauxhall dealers, that deletes the "low fluid level" function. If the software update does not fix the problem, and the fluid level is correct, a new steering pump/ECU/fluid reservoir assembly will be needed. (or just ignore the massage)
check the power steering fluid level. I would have to say your low on fluid.
did you bleed the system properly when changing pump.have you got correct level of fluid in pump. is it the correct pump for that vehicle
Look at the level in the power steering reservoir...
check the power steering fluid level and the power steering belt
check power steering fluid level
Have you checked your power steering fluid level..?
Denise, the fluid goes in the power steering pump resovior at the same place you check the level. Make sure to check the level when the fluid is hot.
If it making a loud squealing sound when you turn the steering wheel, the power steering fluid level is low. The reddish fluid you are seeing on the ground is power steering fluid. It is probably leaking and that would be why the fluid level is so low.
Power steering pumps are self bleeding, fill the reservoir, start the engine and turn the sterring wheel from stop to stop. Add fluid to correct level.
