rollingthunder1994 Posted February 13, 2005 Report Share Posted February 13, 2005 Last Monday my 94-STS started overheating without warning. Hoses were hot, but no heat just cold air blowing. I changed the thermostat, refilled the overflow tank. Still same problem. I took it to PEP Boys, which is two blocks away, only because i thought it need to be flushed. Pep Boys refused to flush the system, because they said Anti-Freeze was leaking through the overflow tube. I only took it to Pep-Boys because i figured a bunch of monkeys can do a simple radiator flush. Any way since they would not do it. I started driving the car around the neighborhood and the problem seemed to have fixed itself. Heat started working temperature stayed between 199-208 degrees. Today started driving the car started to over heat again temp went up to 250-degrees after i parked the car, i heard the antifreeze boiling and bubbling then it started pouring out of the overflow tube. Suggestions please!!!! New Thermostat, Cap, new radiator in April, electric fans working. Do you all think i should put in a new heater core? local shop want $40.00 for new one Link to comment Share on other sites More sharing options...
