    I just noticed squealing noises with my Equinox this morning when driving...especially when I start to slow down for a light. At first I thought it was the brakes...but I'm not so sure now. Any idea what that could be?



    I haven't taken any steps yet...

Kore94, check the tension on the alternator belt. If it's loose enough to not turn the alternator,it won't charge the battery (i get nothing), but a battery will often 'recharge' (not exactly, but close enough) when left alone long enough to the point you'll get a few cranks. I am assuming that if you were to jump the truck it would start, although it might not run after the cables are removed.

If the belt is loose, tighten it up (don't get crazy, just snug enough to not slip), start the truck, and check the DC voltage at the battery. if it is under 13 volts, the alternator has turned to toast from the neglect. In it is over 13 volts, the alternator is ok. In either case, now would be an excellent time to change ALL your belts and water hoses, but it would be 'mandatory' to replace the belt that was slipping, since it will have lost it's ability to hold 'traction' on the pulleys over the long haul...

gbitondo, if your belts aren't slipping, take of the front tire(s) and look at the disk caliper. There should be a piec of metal that sticks out from the brake pads and hovers over the rotor (disc). If the piece of metal is on or near the disk, it has done it's job and annoyed you into discovering that it is past time for new brake pads. If not (but if it only happens when the pedal is pushed, it's almost a given this is it), keep looking and listening for the true source of the noise.

Good Luck!

Volvo engine wont start


Sounds like it's the pump. Did you turn the key (to on position) with the rear seat removed, and listen for the pump (when key is just turned to on / 2nd position without starting) . You should hear the pump make some fluid exchange / pump noise...

Starter motor noise


Sounds like the starter bearing is dried out,(very common on VW) you cannot lubricate them, only way to fix the noise is to replace the starter. I have seen VW starters make this noise for years and still keep working, so it is up to you if you want to change the starter, noise bothers you to much, then you can change it, it will not cause any damage to your engine.

CHEVY C1500 SQUEALING, IDLER PULLEY?


Without hearing the noise I can't tell you for sure but take a spray can of WD40 and with the engine running spray some on the belts if noise goes way that's your problem, if not check the A/C (if you have A/C) the compressor may be binding up causing the belt to squeal due to friction from the tight compressor. To check the compressor remove the belt and turn the A/C pulley by hand (should turn freely) next turn on the key (do not start engine) turn on A/C then turn A/C pulley by hand again. It will be harder to turn but still relativity easy. If it is hard to turn it is beginning to bind.

Turn the AC system off, this includes defrost settings as well. I think your AC compressor is locked up on the engine.

remove the AC relay to shut the AC off all the time. Not sure why it wont start but you may havea security lockout. Fully charge the battery to proceed.

1988 5.7 TBI Nightmare This is the start of what the problem was and is, I had a RV cam installed when the engine was rebuilt a year ago. the cam was not a computer friendly cam so after a round with the rebuilder and discovering the specs weren't the correct ones for the cam I installed a 3702 edelbrock cam and lifters with a 7800 timing chain and gear set after I had tried two chips from Jet and no improved performance and the 3rd chip was to be for the cam and that is what is in the ECU now and I have tried about 5 different BCC chips and the bottom line is the power is there but something is happening its hit and miss the idle will sometimes lope, is stalled when first started and acts as if its starving for fuel or its bogged with to much fuel. the fuel pressure is 10 - 13 psi and I have R/R the TPS, IAC, ESC and knocks device , EGR and Solenoid, MAP, Temp sensor, and the Dist is a Procomp 10001 with a MSD-5526 coil. the Throttle Body was rebuild and the ECM was replaced with a Rebuilt ECM. it will smell rich etc. but with the things that goes on it does not show any codes?? I have no clue just feel stupid this is been a simple thing that is kicking my **** and now its a challenge but still loosing the fight too far in and too much spent to stop,. LOL Help !!!! The BCC is a california vehicle AFBX, 5.7TBI TH400 A/T P.S. the key can be turned of and back on as the engine not dying and seems to correct the power and run problems but will not last goes back to running bad or with problems. ?
