Hi,
Before now, I’ve never had any problems with the cooling system in my jeep. Even on the hottest days, she would stay under 210 degrees. But for the last year, my radiator has had a minor leak that would cause a little coolant to come occasionally drip out. So, I recently replaced the original single row radiator, and installed a two-row all metal model from CSF. I also cleaned/flushed the cooling system, put in a new thermostat from napa and added 50/50 prestone coolant.
Now she’s running hot sometimes, and I can’t tell why. Most of the time, it still runs at the normal 195 degrees, but when driving through the mountains, or highway driving on very hot days, it’ll creep up to about 230 degrees.
What went wrong? Could it be the new radiator? Bad thermostat? Did I do something else wrong?
