Gonna need some help here. Long story short, something happened while my son was driving to school. Coolant light came on as he pulled into the parking lot. I went over and topped it off with coolant during the day, and told him to just drive it home and park it. On his way home the coolant light came on again, but he just drove it the rest of the way home since he was only a mile away. I got home and the reservoir was empty. Looked with a UV light and a lot of coolant was in the valley and had spilled down the front of the engine. I don't get it... All those parts were just replaced. So now I am having anxiety trying to figure out if something deeper is going on like a head gasket. However, I changed the oil this weekend and I see no signs of coolant in the oil. Also, its not blowing smoke, overheating, or throwing any codes (I have GAP tool). As of now I have the intake manifold off and I guess I will do a pressure test again, but should I check compression or do a combustion gas leak test? I guess I will shine the UV light down on the intake valves (I just thought about that)... but, any thoughts on a methodical approach? Wife may divorce me over this thing as our garage doubles as our home gym.
