Return PolicyDon't let your old flathead boil over – keep it running cool with new thermostats from Speedway. These thermostats sit in the water outlets on the top of the head, with the hose coming down over the water outlets, holding the thermostats in place. Remember, every flathead needs two of these!
Learn more about the importance of the thermostat with cooling systems and how they work by reading our tech article. Cooling System Principles.

Suggest that you drill two 3/16" holes in the flange to allow some coolant to by-pass.

What temp of thermostat do I need? since you offer two different degree's of t-stat... what is the correct one to get? the 160 or the 180? I have a 49 flathead in my car that I just bought, and I am unsure of what the original one is. We live in Kansas and it gets hot in summer (over 100 degrees# but it get cold in winter as well. #below freezing) I do drive my car all year round.
