why does my radiator 's crack "yes i mean 2.
i have replaced the radiator two times brand new from auto zone? new cap, thermostat. still cracks on
the right hand side looking at it. Temp reads a little over 240.
I had the same problem on my BMW but I changed it to All aluminum radiator and it solved that!
240 is rather hot, 210 is a more acceptable range. Over 240 is overheating and you will have more problems than your radiator soon. Maybe your water pump isnt circulating coolant anymore or there is a blockage.
just had that problem on a 2000 cherokee, problem turned out to be a head gasket causing pressure to build in the water system, had it fixed, now no problem,
