Today I thought I would put the original temp thermostat back in my truck. What a pig of a job. After fighting with 3 bolts I couldn't see or touch the 4th. Looks like a radiator out or engine out job. Not impressed at all, especially when 1 bolt is so close to the housing you can't get a ring spanner or a socket on it. That was a half day wasted!! The F@!#er can stay in there and freeze it's ass off. Thermostat is fine....nothing to see here...move along. NO I DON"T HAVE ANGER MANAGEMENT ISSUES!!!!
