Works fine for my old truck.
It works and it fit.... couldn't ask for much more
Good fit, I believe the water outlet gasket was sold separately though.
I did the boiling water test on it before install. It passed just fine. I have bought dud thermostats from other distributors before. With a big grin, I unbolted the housing, cleaned it up and installed the new (working) thermostat.
Using on a '53 Chevy. Looks like a good replacement, but I have not road tested it yet.
The thermostat was stuck open when we bought it and installed it. We had to return it and purchase another one.
Nice to get a high flow t-stat for my big block -- need to increase flow
Have not used yet but as always a great value. Thanks Advance
Nice thermostat for the price. Works as needed
