Review on High Performance Stant 10231 Radiator Cap - Vented (16 PSI) by Jacob Seymour

This lasted about 2 weeks before it stopped holding pressure and started leaking. The part is too cheap to go through the hassle of sending it back. Get one at your local parts store for an additional $1-2 so warranty is easy. It gets 2 stars because I bought a few and the rest have held up well.
