Hello group, I fear the worst of things, My 99 Park Avenue has 114k miles, I
had the Radiator flushed and refilled with the DEX Collant, SInce then It
seem like the Antifreeze disapperars, I filled it up to the coolant
line.Within 3mnths time its empty. I check the radiator its full. I see no
leaks, no change in cars driving or idling. I assume the guys would tell me
if there was something found in the oil when its changed. This cars has the
3800 engine. My mother inlaw has the Lesabrea 2000 model hers the same way..
Does this engine use coolant in such a way.
