2001 Chevrolet Cavalier By-Pass Filter System Install

We found this in our customer archives. I wanted to repost (Dec, 2025) as it’s a great example of what you can do to preserve one of these good reliable compact cars of the time. Not yet a classic but it will be one day. Why not protect that engine even more and with the dual system oil changes are made easier. Plus you have a port right on top for oil analysis.

Cavalier Special Install Instructions:

It was a relatively easy install once we knew where we were going to put it. Two sets of the 90 degree angle fittings were used. A BE90 and an SDF34 fit quite nicely in this space. I installed the bypass with 51,118 miles on the engine and 15,000 of those 51,000 miles were with AMSOIL Signature 5W-30.

I now use AMSOIL Series 2000 (now Signature) 0W-30 with the bypass and have gone almost 5,000 miles with no problem.

The bypass kit increased oil capacity from 4 quarts. to 5.5 quarts. and put the oil filters in a much better position to change. We look forward to using this car for several years and based on others results, we expect over, 200,000 miles of life on this one.

This makes the Chevrolet Cavalier even more economical!
AMSOIL offers the best wear protection to compact cars such as the Chevrolet Cavalier.
