About a 8-10 degree improvement over stock t-stat temps before install. My temps are not as low as some folks have reported, so I plan on removing the radiator for a radiator shop deep cleaning & reconditioning at some point since I do not know the complete history of the cooling system and am at 142K now. I have also not back flushed the heater core yet, so that is on my list as well for general maintenance. But I think I am in pretty good shape now with head gasket job last year, recently new belt, all hoses, Motorad t-stat, belt tensioner, water pump this past summer, and alternator last year, and new bearings for both idler pulleys now in hand to be installed this weekend, I hope. I also have the Torque app on my phone to monitor the engine temps now. Hoping all my maintenance will keep the belt running well and not having any problems with pulleys freezing up and causing an overheating situation. Does anyone know if the Motorad t-stat's fail safe is the open position?


FYI, this is how I now fill my coolant reservoir to minimize air in the system. I pour it slow and this gets it well above the heater core, and allows me to cap it off and run the engine while I can see all around the reservoir and inspect the clamps and hoses that connect directly to it. Give this method a try if you are having issues with air always in your system.
