Hi Gang, 1993 Non-Turb, 138k miles, owed now for 15 years. Had a coolant hose under the belly split so replaced all of them and bleed the system including the heater as described here, many thanks for that. Anyway now about every 300 to 400 miles the car will suddenly over heat. Been fighting this for better part of 6 months. i
