Re: Overheating problems 93 ford ranger
I bet you just need a new fan clutch for the fan behind the radiator. I had this same problem once changed everything, thermistat, coolant, and it just turned out to be a bad fan clutch. I changed it in 2005 and the truck was a 1989. Could be an Air pocket as well, but I bet it is a fan clutch, because it cools when you are moving doesn't when sitting.
