    Temperature warms up at 70mph in '74 2002

    Test drove a '74 2002 today. idling and driving around town, the temp gage stayed low as anticipated. Then I hit a country road where I pushed it 70mph and the temperature climbed. Also could smell the heat. I slowed back to 55 and the temp dropped. got back into town and it stay low. Ideas?

    Im guessing the radiator may not have good enough flow to keep up with the RPMs... or maybe the water pump is suspect... I looked under the hood afterwards and everything appeared OK, nothing leaking.

    It's all stock. I want to buy this car so your help is welcome.

    Hello and welcome to the forum! Big fan of the 2002s man! In addition to the radiator and pump, check the thermostat to make sure it's working properly - if that's the fault, take a look at the link below on the procedure to replace it. Please let us know if you have any questions!
