This. Plus, did you overfill the expansion tank? Cold it should be 1-2" over the min. line.Need more info. Spits out coolant where? Does the fan work? Is there enough coolant in the system? During normal operating temperature is there coolant flowing through the upper radiator hose? It'll be hot so be careful but you should feel the coolant flowing through it when the thermostat opens. If nothing then your thermostat could be clogged or stuck.
Are your radiator fins clogged with mud?Mi car is parked a my cousin place right now. He tel me if the ac is off it runs fine gets up to 3/4 on the temp, on the highway it rides fine, and it hasn't leaked fluid, I'm thinking its thermostat I bought it but haven't placed will probably do it tomorrow
That's a good thing to check. Any clogging of fins or bent shut fins will reduce cooling.SilverSport said:Are your radiator fins clogged with mud?
