Engine Cooling problem
1997 Ford Taurus 6 cyl Front Wheel Drive Automatic 125000 miles
We purchased this car 3 years ago and found that the intake was leaking, allowing coolant into the oil. The intake and heads were removed. The heads checked OK at the machine shop. We replaced the intake gasket (with RTV where called for) and the head gaskets. We also replaced the heater core, radiator, hoses, and a complete AC system. Other than a heater problem (not getting hot very fast), the car has ran great from that point on with no overheating problems. The other day, my wife drove home from work via the interstate as she has for the past 3 years. When she exited and came to a red light, the temp gauge started to climb. She drove 6 blocks to the house and stopped. When she turned the car off, coolant began pouring out from under the cap on the coolant bottle. My first thought was a stuck thermostat. I replaced the thermostat and checked for any leaks throughout the rest of the cooling system. After refilling with antifreeze, I let the car run for about an hour with the cap off to help purge any air. The coolant released an air bubble about every 30-60 seconds for about 30 minutes before settling down. It ran for another 30 minutes with no further bubbling. I replaced the cap with a new one and drove the car about 2 miles on the interstate before exiting. When I exited, the damn gauge started climbing. It never pegs out since it immediately returns to about normal when the car starts to move again. When I got it home and opened the hood, the coolant was pouring from under the cap again. With the car off, the coolant pours from the bottle for several minutes before stopping. The fans do come on and off as they should. I really need help with this one. She needs this car for work. Please respond! I have donated in the past and will again when money isn't so tight. Thanks.
