I have an 86 Ranger, 2.3 liter 4 cylinder, and i have been having trouble with me overheating. I have changed the thermostat, water pump, and have took the head off and got it pressure checked. The head checked good for warps and cracks. What else could be my problem? I have doubted the factory
radiator because its only like 1/2 inch thick. Im needing some imput BAD!
