Engine Cooling problem
2001 Buick Century 6 cyl Two Wheel Drive Automatic 98000 miles
My Buick had the low coolant light on intermitently. After three times in the shop (the catalytic convertor also went out) it is still on. Problem is the mechanic replaced the head gasket on that third trip, an expensive repair as oil was leaking into the coolant from the engine. He actually gave it back to me with the light still on. I gather he did not replace the sensor which was gummed up, so I took it elsewhere and they switched out the sensor. Now after a month the sensor is back on solid.
So my question is, since the sensor was replaced, could there have been residual oil still in the coolant which is now gumming up the new sensor? Is it even possible to replace the head gasket without draining off the old coolant? I hope it would be very unlikely that they could have screwed up the repair in such a way as it is still leaking.I can't afford any more repairs. I would appreciate your input.
have the same problem?
