grinding whining noise
hi
this morning on my1998 v4 wrx sti started overheating badly and only cold air came out the heaters. so i thought airlock in the radiator or thermostat problem. so i went to autosave and bought a new thermostat. when i went home i took out the radiator to get access to the thermostat and changed it out and put back in the radiator. it solved the overheating problem and hot air blows out of the heaters but i i think when i disconected the 2 hoses to the power steering reservoir that go over the radiator some fluid came out and the car makes a whining noise while driving and when steering round a corner the steering wheel judders a little bit and i opend up the reservoir and checked the dipstick and it was reading ok. when i disconected the two hoses could there be a air bubble in the system that could cause this noise and how do i resolve this problem. thank you |
did you bleed the pas system after?
Think you are supposed to got lock to lock a few times |
hi the pas system is self bleeding,top up the resivour to max on the small dipstick when cold with -auto transmission fluid/atf/dexron 2(all same stuff) if you overfill it will blow it out due to expansion. turn it lock to lock and whine should dissappear as the air comes to the top.
pas level could be low, if you checked when was hot it would read higher. |
cheers lads i will try that in the morning
if there is air in the system would it make the whining noise which is a little bit loud. also do i take the cap off the reservoir for the air to come out and do i have the car running when i turn left to right. thank you |
:) Hi theres no need just top it to max and refit cap and go lock to lock gently
you may actually need to top up further if theres lots of air in system Id make sure the pas pump drivebelt not loose either ,the belt should deflect only a small distance when moved sideways. loose drivebelt will cause judder and noise. edit ,yes car running mate :thumb: |
hi classicgc8
i think the the belt is fine as it didnt have this problem before i took off the radiator and disconected the pas hoses and as soon as i put everything back on it started to make the noise but i will check it just to be sure.:thumb: there was some fluid came out the pipe that i took the hose from. do i need to take the reservoir cap off when doing lock to lock and does the car need to be running when i do it.:) thank you for your help:thumb: |
all sorted now bud ????
|
Annoying given you don't have to remove the rad to do the thermostat :(
|
I had to take the fans off to do mine. But only to make it more accessible.
|
yea all sorted guys thanks for the help.
i have found out it was the head gasket that was making the overheating problem tho. lol |
