where is all the genius?

 

I had the same problem.....I just dont run it now...

 

Check for air in the coolant.

 

Your A/C puts alot of load on the engine which generates heat. You could replace the thermostat and make sure to use a 50/50 mix of water and coolant. If it does not freeze were you live you could use 40/60 or a 30/70 mix. Water transfers heat faster than coolant. Just make sure you buy a Honda thermostat. The aftermarket ones suck.

 

thanks.....
my friend will check it for me we will see what the problem...

If you run a/c and your aux. fan is not working your eng temp will run hotter then normal.

 

Also ensure that the fan comes on, that the shrouds are all in place and that there is no blockage in front of the radiator.
