How to Install a 22R Alternator

When installing a 22R alternator, it is good idea always to check the clearance between the main positive wire terminal and the block or cylinder head. The alternator post will always have clearance, but the wire connector can bend or installed where it could make unfortunate contact. This could easily cause a fire. Make sure to relate the year, make, and model and engine size to the parts supplier to ensure you get the correct alternator. This has always been a problem in the industry -- getting the correct alternator the first time.
