my truck tends to want to over heat when going up hill to about 3/4 and then comes back down after coming back down. sometimes also when temp gauge is at normal running temp i can hear boiling in the overflow. i have replaced thermostat,water pump, flushed radiator and engine. new radiator cap. any clue as to what it could be?

 

head gasket could be a possibility. mine kind of started out that way. how long has it been doing that?

 

about 2 weeks now. i dont have a choice to not drive the hill. its about 2 miles and the only way home.

 

what motor is it? tranny, miles, year

 

A 3vze which is notorious for head gasket failure, I would perform a test for exhaust gases in coolant (block tester). Any auto parts store has them.

 

it's a 95 3.0. 180,000 miles automatic
thanks I'll check out that block tester.

 

do you think it's a good idea to remove the ac condenser in front of the radiator to get more cooler air to that radiator?

 

nah. unless its like really plugged up it shouldnt matter.
