Engine Temp LA 360

I would be worried if my engine hit 210 just cruising. The temp usually increases if caught in slow traffic & 210 doesn't leave much margin.....

There can be many reasons why the engine runs hot-ter:
- lean mixture
- clogged rad
- fan operation poor
- large gaps around pump impeller blades reducing pump efficiency.
- no shroud or not sealed to rad core
- retarded ign timing
- insufficient timing at idle
- & more
