I finally got my autometer gauge hooked up, and it says my motor runs between 200 & 210 degrees. I think it should be running between 170 & 180, but not too sure. if it sounds like it's running too hot, what can I do to cool it down? it's an H23, by the way. thanx!

 

190-220 is normal operating temp depending on local weather conditions and motor age, condition, and useage.

over 220 is pushing the limits of the stock cooling system.

 

well, the motor has 160,000 miles on it. should I upgrade my radiator & fans?

 

why? it's worked fine for 160,000 miles so far.

 

get your radiator flushed, or flush it yourself

 

through some redline water wetter in there.
