Hello all. Scanned the faq and not seeing my pair of problems exactly. I replaced thermostat gaskets on both cars today and it didn't help either one.

A week ago, stuck in rush hour highway traffic, car started spewing steam. pulled over and saw coolant shooting from a hole in the upper radiator hose like a geyser. it did not overheat though was getting close. I moved the clamp over the hole, got home and replaced the hose and thermostat (but not the gasket until today). Thought I was back in shape, but I'm still losing coolant at rate of maybe a gallon a day, enough to knock out the heat. can't tell from where except seems the drivers side. radiator and water pump look fine. coolant dripping under engine when running. any thoughts on how to track this down? oil on the stick looks normal.

coolant has been seeping from thermo housing (or very near it) for a long time. I finally scraped away the alien gunk that looks like it came out of a bat cave, and replaced gasket. no better. maybe even worse. I cleaned the mating surfaces. should I replace the housing? is there sealant/liquid gasket in a tube for the mating surfaces? I've got those nuts cinched very tight.
Sorry to go on so long....this is a 2-in-1 deal. Thank you in advance for any tips.
