I have a '99 Nissan Frontier 4cyl. p'up and the air
conditioner kept going off. The truck has three
drivebelts, all inline. The first is Crankshaft to the
Power steering pump , the second goes from Crankshaft
to the water-pump & the alternator and the third one
goes to the air-conditioning compressor; the one that
keeps coming off my truck & shutting down the A.C. I
replaced it three times and the last time it went off
within a couple of miles. I know the crankshaft and
the A.C. compressor pulley's are out of line and
believe that's my problem. A mechanic friend of mine
looked at it and said he thought it was something
called a belt-leveler that keeps all the belts from
slipping off. He wanted $550 to fix it. Does anybody
have a clue as to the problem because if it's the
crankshaft pulley I don't see a way to fix it & nobody
else has ever heard of a belt-leveler?

Keith,

The Pulley's have to be in alignment. Maybe the Slack Adjuster Bearing's have worn out,, and throwing the Belt out of alignment

Is this a Truck that you just got?

Nissan would be the best place,, but if you don't want to take it to them,, then I might go to Firestone, or a professional AC Specialist.

Good Luck

Rubble,

What are the slack adjuster bearing's exactly? I've
never heard of that but I'll check it out. The thing is
that only the third belt, that controls the A.C., slips
off, the other two keep turning & I can still drive the
truck but with no air. I've had the truck for 12 years &
fixed everything myself until this.
