Review on Optimized Heater Valve by Four Seasons - Model 74795 by John Miller

I agree with the other 1 star reviewer. In my opinion this product is poorly assembled leaving the top vulnerable to leaks and potential catastrophic failure. As a result, your coolant will splatter onto the exhaust manifold and grind up fairly quickly as the top/inlet separates from the rest of the valve body. I first bought the Dorman version of this valve locally but found it must have been assembled incorrectly. makes it totally undesirable to use. Since the 74795 valve was available locally and seemed to be the right design, this was the first valve I tried; However, due to a leak and possible catastrophic failure, I also chose the Delco AC version of this valve and have had no problems since. Instead I would recommend a Delco AC valve or an OEM valve. If Chrysler could manage its supply and make it readily available, it would simply use an OEM valve. Waiting months for an OEM replacement is ridiculous.
