My 07 Ion runs hot when I get to way speed. I've flushed it,

Customer Question

My 07 Ion runs hot when I get to hi way speed. I've flushed it, replaced the coolant, new radiator, tried 2 new thermostats. The fan comes on when it should, but the lower hose never gets as hot as it should. No external leaks. Is there a way to test the water pump? Might the head gasket be bad? Theres no oil in the coolant or vice versa.

Does it ever loose coolant?

Customer: replied 1 year ago.
Doesn't seem to. If so, very little.

Hello!

Sorry for the delay...

If its not loosing coolant then the head gasket is still good. Diagnosing the water pump includes seeing of both hoses are hot and in your case they arent making the water pump the only thing it can be thats wrong.
