Mr. Gasket 2476BK Domestic Thermocap

Looks good and it's definitely accurate, unfortunately it doesn't hold tight enough, it leaks through. But it holds the pressure enough to not pop off. It didn't work for me but it might work for someone else.

Easy to read dial Only thing I don’t like is the dial can move and make your reading incorrect. I had to use a laser thermometer to set the temperature correctly after accidentally turning the dial removing it from the radiator.

It's only been a few weeks, but it is working great and accurate. Main thing is this has the proper PSI rating for my radiator, so no leaks. I had to muscle it on a little to make sure it fit tight. I put this on a 1965 Impala because it only had a dummy light before.

I am not sure of its accuracy. It will take more time. I bought one for my Camaro which seems to be accurate but the one for my Jeep needs further review. Camaro dash gauge is known to read high by 20 degrees or so. The gauge on the Jeep just does not have a good scale on the gauge. So I bought it for when I tow to see how high is high.

It works for me an my 1982 el Camino

I thought it would leak antifreeze

I have run one for years, but that one started to leak around the glass on top of the cap. I became spoiled by it and had to get other one.Love these caps!!!!!

Good fit on Champion Radiators, great design and durability. It does seem that the thermo cap is approx 12-15 degrees higher than the running temperature. I would use this cap as another tool but i wouldn't rely on it.
