Hi all I have question. My gf car starts making this noise. The noise would go away as the rpm rises but when I let go of throttle the noise come back. Two of the belts (AC/ alternater and PS) are pretty tight. I was wondering if anyone has any ideas of what it could be. Could it be a loose timing chain due to bad tensioner?
Okay so the hose will kinda filter the other noise away right? Say if that weird noise is coming from the pump, i would hear the loudest noise from that location. I will hit homedepot this week. Thx Dane.
Alternator check: Check Voltage of battery with power off. The turn car on, check voltage and watch to see if it slowly drains and goes below 13 volts. Also, check the voltage drain with all accessories on
A/C: Cycle A/C switch on, and if the noise changes, it may be the compressor
nope no overheating or anything. It drives perfect and has lights. Its just the noise that bugs me. I decided to go buy new belt and will be put it on sometime next week when I have a chance. I think its prob the belt since the noise change when accelerating and increase acc. load.
AC blower cold also. The noise doesnt really change when I turn AC on and off but it does when I turn fan switch on and off, so Im not sure if its the compressor. IS there any other method to test the compressor?
