I am trying to help my computer challenged father in law with his 2000 Intrigue. I love this forum, I use it regularly for all of my vehicles. The father in law can't figure these out. Anyhow, he has a 2000 Intrigue that developed a sudden and massive coolant leak. He shut it off one night and woke up the next day to find coolant all over the garage floor. I would suspect a head gasket, but there is absolutely no coolant in the oil. If it was a head gasket, wouldn't there be coolant in the engine oil? My next guess would be the intake manifold. It's difficult to find the source of the leak as there is coolant everywhere now. This engine never ran hot or overheated in the last few weeks, or at all for that matter. Any past experiences?
