What degree Thermostat?

Some people forget (or just don't know) that a thermostat controls the minimum operating temperature NOT the maximum operating temperature.

I love Dan's post and it is a great reply to all those "I have been running "X" part and never had any problems". Sometimes you never do see the problem but when you are rebuilding your engine at 85,000 miles and your buddy, with the same engine build, is refreshing his at 180,000 miles, that 160 stat could be the cause.

"It's like smoking: you won't notice any problems now or next week or next year, but eventually the gradual damage will make itself apparent. With your too-cold thermostat you're throwing away gasoline money and causing unnecessarily rapid engine wear."
