1999 ford ranger coolant troubles
I have a 1999 Ford Ranger with a 3.0 Flex fuel engine. I runs fine but blows antifreeze out of the overfill tank. Also the temp. guage seems to move a lot and very fast. The antifreeze is rusty brown. I have flushed it out and put a new thermostat in it. Is it a blown head gasket or is there something else I can try.
