1992 Isuzu PU Overheating. I have the V-6 in the 4x4 model. I put in a new radiator, changed the hoses and thermostate and it started running hot. Was fine before I did all of this. Changed out the fan clutch. Made it a little better , but still runs hot espically at low speeds or stop and go driving. Any suggestions? It's been like this for about a year now. Is there a coolant rely switch somewhere that I should know about?
Thanks
