got 175K with no issues runs great! but lately my check engine keeps coming on,my mechanic keeps reseting cause is just something related with the gas cap " he says" . Then everytime i hit a puddle my A/C light flashes and it stops cooling,all i do is turn the A/C off,wait and then turn it on and it works.I also wana go bigger in tire size.I have 225/40/R18,and want to go with 45's tire.Anyone have the same issues? maybe it could help.

A slipping belt will cause your AC problem

Replace your serpentine belt and adjust the tension properly.

and replace your gas cap, if thats your check engine problem, its a real inexpensive fix. if that dont fix the light, you can check it off your list and go to the next common cause. be sure to clear codes after replacing the cap, then check the, if it comes back on.

Why would going over puddles cause it? so the squeak after i hit a puddle must be cause some play in the belt? i was thinking maybe the bearings on the pulley.The check engine light was reset by my mechanic,let's see if it does it again.thanks guys

lol everything you mentioned seems like your Mech suxs.....but you mention tire size....you do understand there is a simple search function that may get your info faster then waiting on others to reply...also get the codes from Mech to better answer your concerns...I say follow the responses by the forum members so far.

I assume you mean the engine belts, especially the one that drives the AC compressor. This car does not have a serpentine belt.

A single, continuous belt used to drive multiple peripheral devices in an automotive engine is called serpentine (like a serpent) belt...

Often when people speak of "Serpentine Belts" they are referring to the flat ribbed style of belt having the idler pulleys and automatic tensioner running on the back side of the belt.

VS .......the "V" belt that normally uses a static tensioner -- they normally need to be quite tight also.


I'm not sure what kind of AC clutch that vintage has. Many AC compressors have an RPM monitor to disengage the clutch if the compressor seizes up -- so any discrepancy in the RPMs -- like a belt getting wet in a puddle -- will trip the system to turn off the clutch.

Yup.

This engine has TWO belts. Neither has an idler or tensioner pulley. The PS belt is tensioned by rotating the PS pump (and it's a PAIN to reach). The other belt drives the alternator and AC compressor, tension is set by rotating the alternator.

No serpentine belt.

If having an idler and/or a tensioner pulley was a necessary condition to characterize a "serpentine belt" then I would agree with you. However, this does not seem to be the case ("The belt MAY ALSO be guided by an idler pulley and/or a belt tensioner..."). Of course this is just a matter of definition.

Thanks for the advice guys.I'll have my mechanic take a look at the belt and tension.
