Don't let that flattie 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!

  • OEM replacement
  • Two thermostats required for each engine
  • Opens @ 180° F
  • Fits 1937-1947 Ford/Mercury flathead V8s in cars & trucks
