🔥 Four Seasons 74662 Heater Valve: Efficient Heating Solution for All Seasons Review

As my tests showed, this valve is the perfect replacement for my old one. It functions smoothly and accurately regulates the flow of coolant in my car's engine, keeping the temperature at a constant level. The installation process was quick, and the valve seems very durable. The only drawback is that it's a bit more expensive than some other models on the market, but I think the quality justifies the price.

The lower intake is not the same as the stock but I don't care. You need to make a clamp for the control cable jacket, the AMC clamp will not fit. Works perfectly. Some attention has been paid to the design so that at very low flow rates (small orifice) accurate heater control is achieved. Cheaper plastic valves tend to be linear proportional, which is not suitable for temperature control.

As a warning to those using this valve for repairs/conversions, you can grind and pry the actuator minimally, bend 4 tabs and then reposition the valve to fit it conform to factory specifications, reinstall the valve body, and reinstall the actuator to its original function. a very flexible use is possible, which is not immediately apparent. Otherwise it works great, just as if not better than the original.
