Well, I had my compressor & PS belts replaced. Now, they squeal on start-up, which I understand from reading other posts means the belts are probably too loose. Does anyone know the deflection specs for the belts?

Also, my mechanic said I needed a new tensioner pulley bolt (he probably damaged it). When you buy a replacement bolt does it comes with all the needed hardware (spacers, washers, nut)? I read in a post that you can buy kits to replace the belts- other than the belts and bolt(s), is there anything that I am missing? I want to make sure I have good hardware to minimize the noise.

Thanks!

I dunno about the parts but for deflection,

at the bottom on the main belt, set it to 90 degree deflection...

 

Thanks for the info . . . I have learned that there is a kit assembly that one can buy from a Nissan dealer for $40 or you can buy parts individually, like a tensioner pulley bolt for $11.

 

Belt Deflection is as follows:

Limit After Adjustment New

Alternator with A/C 7 4.2-4.6 3.8-4.1
Alternator w/o A/C 10 6.3-6.9 5.8-6.2
Power Steering 11 7.3-8.0 6.5-7.0

Applied pushing Force 10 Kg or 22 lbs
This is measured from the bottom of the car pushing upward on belt, pushing midway between pulleys.

 

That didn't format properly
There are three measurements
Limit, Deflectection after adjustment, Deflection of new belt.
The numbers below represent these three headings. The first number is a whole number ie 7,10, 11 the others are ranges.

 

Forgot one thing the reading are in milimeters.

My only regret in life is that I can't remember everything I know.

 

Thanks for the info.
