Review on Motorad 439 180 Thermostat by Chris Sandridge

Immediate help for my heater/defroster. Also, the engine now runs cooler and happier. You will also need to replace the head gaskets as this allows the water to flow freely. Too bad there aren't any microscopic elves here, popping up in the cooling system, fixing leaks and breathing 200-degree coolant. Ease of installation.
