🖤 Black Stant Radiator Cap Review

I bought this for my 1987 Dodge pickup because I like to depressurize before opening the radiator. This is the perfect old style cap.

I converted a "sealed" system (13 PSI cap) into this cap and reserve tank. The cooling system works MUCH better now because all the air has been removed from the block. Before (with the lid closed) there was quite a lot of air in the cooling system.

I had a 7psi cap on a 66 C-10 and it was getting hot and losing water. cover succeeded with flying colors. My operating temperature is lower with less coolant loss. If I'm lucky I'll try a 13psi cap. Oooh! life is dangerous

Just what I needed. Pretty easy to take apart. I stole a spring from it and attached it to the top cover of my Subaru STi to allow air to escape from the cooling system. The head gasket has a slight leak and this workaround allows me to run the car in the summer so I can fix it when I use it for the winter.

Used on K1500 4x4 5.7L 90s with factory coolant overflow tank. After installing a new radiator with new top and bottom pipes and a thermostat, I wanted less pressure in the system. Due to the fact that the truck with high mileage is old. This 7lb cap reduces pressure over the factory 16lb cap. The regeneration reservoir works as it should, with hot and cold levels, and draws back some coolant as it cools. I'm also considering using it on an old classic V8 car for the same reasons to reduce…
