What's in the Box

Info

Don'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!

  • OEM replacement
  • Two thermostats required for each engine
  • Available in 160° F or 180° F
  • Fits 1949-1953 Ford and Mercury flathead V8s

Learn more about the importance of the thermostat with cooling systems and how they work by reading our tech article. Cooling System Principles.

Keeping it Cool

February 01, 2016
As with all thermostats, there is always a little tolerance, Having a flathead with different temps can be a little unnerving, both thermostats opened within a degree of each other, and held 180 degrees solid.
Pros:
  • Temp On Target
Yes, I recommend this product.

Have purchased before and as always works like a champ.

July 28, 2015
As always, quick delivery. A very nice product but in my opinion gaskets should be furnished with the thermostat, not the goose neck.
Yes, I recommend this product.

Ford Flathead parts

May 25, 2014
I thought I'd do an overall rating on Speedway, as I've made many purchases of items for my 1949 ford engine. Every item from water pumps to offy heads and intake manifold, oil filter to chrome goodies. All items surpass my expectations in quality and performance. Your commitment to good customer service is second to none. I'm a very happy Speedway customer. Thanks, Gary Clarke
Yes, I recommend this product.

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.

If the car is the original either will work. However, if the car is modified, or the car does not have the amount of air surrounding the engine as the original, than use the 160.

The 160 degree thermostat is the more commonly used, I would recommend the 160 for the all around conditions you will be driving in.

These thermostats are for the 1949-53 Fords and are 2 1/8” diameter. If needing a thermostat for the earlier years we offer part number 91015801 and for the 1938-48 Fords measure 1 7/8”.

Yes, use part #91015801 for the '46 flathead
