🔥 Heater Valve for Four Seasons 74781 Review

Thanks to my knowledge gained in practice, I can guarantee that the Four Seasons Heating Valve is a top-quality addition to any automotive cooling and climate control system. The valve fits seamlessly into the system without any issues, providing optimal heat circulation even in extreme temperatures. The build quality is outstanding and ensures long-lasting durability. One downside is that the price may discourage some budget-conscious buyers, but overall the Four Seasons Heating Valve is worth

Perfect for my '99 Chevy Suburban K1500. The original had a small tear around one of the tube ridges, but it has lasted almost 18 years. This replacement turned out to be identical in all respects, it was easy to install and immediately started working.

I've ridden this valve less than 500km and used it as a heater bypass valve. Today one of the pipes ripped off the valve and poured all my antifreeze on the track. I went to get it out of the car and the other nipple broke. The plastic was so brittle that it crumbled easily.
