I need to change the alternator belt on my 93 mitz...3000 GT sl. I have no turbo. I do have manual tranny and standard air condition, and two wheel drive. How do I adjust the tension? Thanks for any help you can give me.

Sounds like a vacuum leak or open air filter box. Check all vacuum hoses are in good condition and make sure air cleaner is closed properly.

Hello Kim,

What type of vehicle are we discussing here? Engine? 2 WD? Transmission?

Is the whining noise present at idle?

Is your vehicle air conditioned?

I need some details to provide assistance.

Should just be the serpentine belt and then the alternator, it is a little tight to work area wise.

My best advice is to pay a mechanic to do it! Access to it is a nightmare! Jacked up with a wheel off and the wheel arch liners out!!
You will also possibly need to remove 2 auxiliary belts to do it. (Depending on if you have AirCon fitted). A longer, outer belt and the shorter inner 'stretch' belt.
The alternator itself is held in place with two bolts and the electrical connectors on the back of it. One large wire and one small connector.
One of the smaller pulley wheels will be on a spring loaded arm to give you the slack needed to remove the longer belt.
For the shorter belt you might need to slacken the mounts on the air conditioning compressor to release the belt. To get access to the alternator.

What ever reason you changed it for, the alternator had too much preload on it and now the alternator is bad.

Thanks for using FixYa.

Power Steering Belt

1. Raise and safely support the vehicle.
2. Remove the right front wheel and belt splash shield.
3. Remove the air conditioning compressor/alternator belt.
