Heating problem
Hey guys maybe you guys can help me out,. I've been having a problem with the car heating up past 220 (half mark). When the ac is on the car tends to overheat for some reason, and yesterday I was driving up a hill no AC on and the car started to heat up so after the hill I threw it on neutral and the cars temp returned to normal, I've changed the radiator, thermostat, the water pump, checked the hoses, and the antifreeze but I still keep having that problem. If I drive around in the summer just on the streets with the AC on I have no heating problems but If I take it on the freeway it goes way past 220 almost to the red I haven't let it climb that far. Hopefully you guys have an idea on what the problem could be. I'm thinking it may be the headers gasket but before I dive into that mess I was hoping to get some ideas on other possible problems, I think the pressure returning to the engine from the radiator is too strong and when it goes to the radiator it's not enough, Thanks guys
