Review on Dorman 902-313 Engine Coolant Water Outlet: Ultimate Cooling Solution for Optimum Performance by Jeremy Choi

I needed to replace the radiator on my van (2007 Dodge Grand Caravan SXT with 3.8L engine) and decided to replace the hoses and thermostat at the same time , because I hate draining and refilling cooling systems. I didn't trust the existing 12 year old plastic thermostat housing so I bought it while I was at it. It fits and seems well put together. Problems I encountered during installation: - I wasn't sure whether I needed a gasket around the thermostat or a gasket between the housing and the engine. The Stant website (I used a Stant thermostat) only lists the gasket. Other brands of thermostats mention a seal. This body came with a rubber gasket, which is what my van needed. No replacement mounting hardware was shipped with this chassis. My screws were rusty and I had no intention of reinstalling them. I got a set of hex head screws from my local parts store to install it. The screw size on my van is M6-1.00 x 30mm. I don't deduct a star for missing hardware, but that's only because of the price I paid.
