Squealing fan belt on start up VQ25DET

[conan7772]

Does the M35 have an auto tensioner?

Any tricks to fix..

cheers

Negative. And probably just needs new belts

[conan7772]

it has new belts, and started squealing straight after they were fitted.

only squeals for 2-3 seconds but it's really loud.

where is the tensioner ?

On cars I've worked on previously (Not Stagea) squeaking belt after fitting new one usually means not tight enough.  

On start up the alternator is placing a heavy load on the system that that usually causes the extra strain/slippage on the belt.

Both belts have manual tensioners that you tighten from underneath.

This link has some good pics (same as M35 Stagea). http://forums.nicoclub.com/howto-change-engine-belts-t529305.html

Try putting anti-squeal, soap, wax etc. on one to eliminate which belt is squeaking then try 1/4 turn at a time on the tensioner to see if it fixes it.
