RE: Getting hot on freeway but not idling in city |

Lets start from scratch. What kind of car is it in? Does it have a crossflow or downflow radiator?
Crossflow radiators have a bad habit of clogging in the lower rows. The way to tell if you have a clogged lower section of a radiator is simple. After the engine is up to operating temperature, shut the engine off. Feel the radiator core from top to bottom. The core should be hot all the way down. I have found clogged radiators with as much as the lower 1/3 of the core cool to the touch. When replaced with another radiator, the overheating problem was solved. |
