🌡️ EMP/Stewart Components 301 Modified High Performance Thermostat - 180°F | Varying Colors Review

My 55 was overheating so I replaced my thermostat with this high flow model. Works great as it can be. The peak reaches 180° and stays there.

Works so well, almost too well. Now it is difficult to heat to 180 because of the trickle hole. Likes to stay at 160 for a while. Cools the engine down quickly when accelerating.

Works well and the extra holes allows water to circulate in the cooling system where there is no bypass. I think it will work well in bypass cooling systems too.

Works great so far and no complaints. Fits snugly and flows well with my heavy duty pump installed on a Stroker 383. Expensive part and only time will tell if it's worth the extra cost but I hope it doesn't fail at the worst possible time like cheap thermostats.

We have used these thermostats for many years and will continue to do so! As long as they are available. Difficult to find/buy at any 'local' auto parts chain. Now exclusively via "Online" or "Mail Order". A note to potential buyers. The vehicle takes longer to warm up/reach normal operating temperature. If you live in a colder (winter) climate, suggest using a 195 degree thermostat.
