PROBLEM 92

1992 Buick Regal • 200,000 miles

92 Buick regal. Low coolant light comes on very dim as soon as engine is started. Coolant is not low. After only a few minutes, low coolant light goes out and overheat light comes on very dim. Engine does not seem to be really overheating. Radiator cooling fans are not running at that time, but will run if engine is revved considerably, or if AC is turned on. Changed thermostat, water pump, and flushed radiator, no change. Any ideas? Thanks, Ken

May just be ban earth problem, ensure all engine earths are clean and tight, start here.
