Hayden Automotive 205 Thermostatic Sandwich Review

Thanks to my knowledge gained in practice, i was able to install this sandwich adapter with ease. The thermostatic feature keeps my engine running cooler and the double design allows me to add multiple accessories.The only downside is that it does add a bit of weight to my engine..

It uses a small coil spring that folds when heated so the oil pushes on it too, sort of like a back door. The problem is that it is a bypass for cold oil flow and the hole is about 1/4 inch in diameter. When working with 5w30 synthetic and around 16 degrees outside temperature, it takes 3 minutes for the oil to reach the upper limit. Motor reports full pressure. I was wondering where the squeaking came from after fitting the top, which explains that. It actually allows the use of an oil cooler.
