I have had cooling system problems since January. The system overheats. The low coolant light comes on, the gauge needle usually climbs, sometimes to the top, I have no heat, and when I shut the engine off I hear the thumping noise of water boiling in the engine. When cool the overflow tank usually takes about 3 quarts of water. Sometimes when I add water to a warm running engine it comes right out the overflow tube all over the ground. On a few occasions boiling water and steam came pouring out of the system.
There is no sign of water mixing with the engine oil, nor is there any white smoke coming out of the tailpipe. The system and heater core have been backflushed a few times, and bled for air pockets thru the coolant air bleeder multiple times. The surge tank cap was replaced. Nothing has worked. What do I do?
