I have had a problem with my 2002 Honda civic LX since I have bought it. It has brand new radiator, brand new thermostat, brand new radiator hose, and Brand new cooling sensor. I have had it in the shop twice to replace those things. I drove 3 hours the other day and it kept running hot on me. It ran more hot when I stopped or went slower speeds to the point where I had to cut it off for a minute. I cannot figure out what is wrong with it. No blown head gasket because no milky substance in my oil. My old mechanic suggested external transcooler for transmission, another mechanic suggested water pump or new fan. Help!!!

Not a 10th gen Civic...

You have a bad head gasket. Read some of the other threads in this section including the one linked below.

Head gasket, your mechanic doesn't know how to diagnose it properly on a Honda. Go read that link
