Review on High Performance Stant 10231 Radiator Cap - Vented (16 PSI) by Matt Welch

This is a radiator cap. There isn't much more to say here. I have a coolant leak problem. There is no leak but when the engine is warm I can smell coolant in the engine bay. I thought the bearing cover is 18 years old, let's buy a new one. The old one may open at a higher pressure than recommended. That got me on this path. I can't tell yet if this is the end of it all.
