            Great Addition/Replacement

            I purchased this cap for the Moroso aluminum overflow tank for my 88, still need to modify the harness to work but is what's needed to make it work on my year. Good product, fast shipping as always.

            Rad Cap with Sensor

            Perfect swap for factory unit. Plugs right into factory harness. Old unit had my low coolant light showing in the dash. This solved my problem. Product arrived quickly.
