I just bought a 96 2wd ram 1500. 97k miles. 318 runs good. It does however squik i guess at idle. Just kind of noisy at idle under the hood. It also has a psst (like an air comprssor going off) when the truck is turned off. The noise sounds also like a noisy belt but a new serpentine has been put on recently. It is uneffected by turning the a/c on and off.
This is my first Dodge so I'm new to any dodge qwerks.
No codes have been generated. Also noise only appears after truck has warmed up. I replaced belt and checked tensioner (looked ok) Also spun all pullys that can spin and all felt pretty good. I'm starting to lean tword fan clutch and or water pump. THe pump shaft had I guess 1/8" or less play in it but I guess could be going bad. any thoughts?
OK ive replaced the water pump and fan clutch and i thought noise went away. It has come back but louder. It is definitely something belt driven but I cant seem to isolate. it is driving me crazy. all belt driven accesories work fine (ps pump-ac-alt) I'm leaning tword the ac bearings? the noise is still there wether ac is on or off.
Noise only starts once engine has warmed up
goes away above 1500 rpm
lastly it kind of sounds like an air pump turning off -when engine is turned off (like a pffst sound?)
I really dont want to start replacing everything need help
Im glad to hear your not having any more squeaks. The tensioner is usually the first to cause issues. I was going to point out a cheap way to isolate noise locations is to use a form of stethoscope, staying off any moving parts and away from them as well, but you can get close enough within a few inches of a pulley safely and should be able to hear it if its squeaking.
