A couple of months ago I installed a new radiator, thermostat/housing, water pump, and upper & lower radiator hoses. I used AC Delco parts. A few days before I did the work I flushed the system with distilled water until it was running clear.
I believe most of the coolant was removed while I had the pump and thermostat out. After I installed new parts I filled the radiator with 50/50 mixture of distilled water and DEX-COOL and then filled the recovery reservoir to the "Fill Cold" line.
Over the course of the next several weeks I have noticed that the reservoir level rises to the point of overflowing. Each time it does this I siphon out enough to bring it back down to the "Fill Cold" line. Thus far I have removed approximately 8 quarts of coolant! Each time I siphon fluid from the reservoir I check to ensure that the radiator is still full.
Alldata specifies that the coolant capacity for this vehicle is 13.9 quarts. I am perplexed at how I could have removed this much coolant from the system. I have not had any issues with vehicle performance. I have put about 1500 miles on it since doing the maintenance and engine temperature is always stable at about 210 (as indicated on dash gauge). Heater and A/C are functioning correctly.
What the heck is going on?
