gatorback install now have a problem maybe??

[4.6boy]

well i installed my new gaterback blet (6rib 93.5 in)on my 02 gt. i diffently got it right. i drove about 20 miles and i noticed when i would hit the gas i would here a clunk soundcoming from the front. then i noticed the oil gage was move back and fort just one point (it does it only idling) the car is running good and the belt is on good what can this be?

also my intera lights were diming when this was hapening

maybe the belt is screwing up your Alt.

installed correctly? the oil pump is crank driven, so the only think that should cause the gauge to act funky would be an electrical fault.

Check the belt tensioner and idler pulleys. My 02 GT vert had an alternator issue where the battery light would turn on at high rpm when I was really getting on the throttle hard. The lights would dim and then return to normal (sometimes) when the RPMs fell. I assume this was the alternator/voltage regulator going bad.

I replaced the alternator, tensioner, and belt and problem solved.

If you have to replace your alt, check out rockauto.com Really great prices! TIP: don't buy a remanufactured alternator, buy a NEW motorcraft unit. I bought a reman and it doesn't put out enough juice to feed my stereo amps.

As for your oil pressure issue, who knows? The sending unit is electrical, if I am not mistaken. If your electrical system takes a dump, it seems logical to find a correlation between the oil pressure symptom and a deeper loss of power issue.

I would check/replace the tensioner first, then the idler pulley(s), then the alternator. Start with cheap fixes first.

Another thought, you said you hear a CLUNK sound?

Make sure all belt-driven components are torqued down properly.

Check the alternator mounting bracket, tensioner, power steering pump, etc.

Torque them down to service manual specifications before you go buy anything.

i never had any problems with the oild motorcraft belt also the clunk only happens when i would get on the gas and then let it go and then hit the gas again also the tensioner was ez to move over when i was taking the old one off

also when the car is idle and i rev it up there is no nosie or anything and now of the pullies vibrate or move side to side ( is there more the then one way this belt could go on)
