Thermostat housing
Found that I only had a leak since the sensor clip wasn't holding the sensor in tightly. But since I had the bright, new, shiny part in I figured that I'd install it and give myself a peace of mind over having the original plastic housing in place!

The product was accurately described. It fit perfectly and is way better than the original! Your videos are very helpful and l use them as needed. Thank you!

No problems thus far
Haven't had any problems in the past several months, don't tighten too much if installing it yourself & place it down evenly or it'll leak.
