basically my car has never had over heating problems. i would sit in summer traffic in arizona at just over 185 degrees. i did a cam swap, the car ran a bit hotter, put a new a/c compressor in, car would never get over 210 even sitting in standstill 112 degree traffic. lately now with no a/c on or with on the car will get to and sit at 235 degrees. before when i had no a/c it would hang out at 185 or lower just driving around on the highway. i am not sure what it is. there is no air in the system i am sure of that. i have a manual fan switch that is always on. i am thinking maybe a bad thermostat? what does everyone think?

oh yes, and the car has a 160 degree thermostat that certainly probalby has at least 100k miles on it that i know of. car currently has 136k miles.

 

You can remove the thermostat and test it in a pan of water. Make sure you have not sucked up any debris in front of the radiator.

 

isn't the thermostat designed to fail in the open position??

i say check it..

but it could be that you're waterpump is failing or that you have a blockage in your radiator.

 

Yeah check to see if she ate something, these cars are bottomfeeders. Also check to see if your primary fan is still working, the motor may have taken a dump. (I got a couple of extras sitting around )

i'll take a look at the fans, then i'll check the radiator.
