1998 Marquis overheats on really hot days but not during an 80 degree day. I've flushed the radiator and cut out the middle of the thermostat so it would keep flowing. I dont know what to try next radiator replacement or a waterpump. (not leaking from weep hole) no fluid on the ground at all. Oil isn't milk shaking either but intake was replaced about 5k ago Any help would be great thanks.
 
It has an electric fan that turns on and off perfect but it over heats driving and sitting just worse when it's sitting
 
i would also replace that stat with one that is not drilled out, that will cause issues as well
 
Pulled radiator and was defiantly clogged up full of debris. Blew out and put back that looked like it's main problem. And put back it's stock thermostat. Thanks for the help
