2.2L and 2.4L engine belt routing diagram.

Question: How do put back on the alternator belt on 03 Oldsmobile Alero? I know what it looks like I need to know how to loosen the tension. 2.2 liter Ecotec.
 Answer: You will need to pull up on the serpentine belt tensioner. It is located just above the large crank pulley. In the center of the pulley is either a 15 or 13 MM Bolt head. It is very hard to access from under the hood. The best way is to remove the inner fender splash shield. Or purchase a serpentine belt removal tool from a parts store. It is a very long and thin bar with a socket end to get onto the tensioner.

Question: There is the plastic shields behind the wheel that helps prevent water and mud from splashing on the engine. So I will have to get under the hood to do this job. What if I can get under the hood ?
 Answer: You can do it from under the hood or from through the fender splash shield. Either way it is very tight and hard to get to you with an open end wrench. There is a special serpentine belt tensioner tool you can buy at the parts store. It is long and very thin so you can get down to it.
