The Superstat has the added features of a heavier frame, spring and heat motor for more control and longer life. Its unique, patented valve promotes extremely fast flow as the thermostat opens to reduce cycling. This thermostat offers a longer life so you do not have to change the thermostat as often, promotes improved engine efficiency from better temperature control and provides high flow.

I bought this to replace the stock type thermostat as preventative maintenance in my 1973 Chevy small block 350. Before installng, I tested this thermostat and my old one in hot water with a candy thermometer. Both started to open at 180F as they should, but this one reached full open at a much higher temperature than the old/stock one. I believe this is due to the stiffer spring. As a result, when installed it kept the temperature over 210F, a good 20 degrees higher than the old one. I do not believe it flows more as claimed, based on looking at both thermostats at full open and comparing the open flow area. It is definitely well built well but runs too hot for my liking. I pulled it out and put the old one back in.

                  Great question, Jay! This part does not include gasket or water outlet o-ring. The size of the gasket depends on the application, but a common gasket number is the Stant number 25138. Currently, this product is unavailable online. I would suggest that you visit your nearest Advance Auto Parts store to check the availability of this part.

                  The best temperature rating thermostat is the one that originally came in your vehicle. Unless you are doing extreme racing, there really is not a need to change the temperature rating on the thermostat.
