Jeep Story: I had bought it at the end of December. The Previous owner only had it for a year. It Needed some work when i got it. The water Pump was Bad So i replaced that. The jeep Also Needed a New Master Cylinder so i flused the system and replaced the Dot 5 with Dot 3. I drive the Jeep back and forth to work eveyday It's a Short drive but i let it warm up in the mornings or purposley drive it around till i get hot air coming out of the Blower. On weekends i will drive it all day long on various errands. When i found the goo under the cap it had been after driving the jeep at abotu 45-50 mph for about 45 min to an hour.
In regards to your thermostat question i do not know for sure what's in it. I am guessing that it is not the 195 thermo because it seems to take a while to generate heat.
Other cases really noticed and loss of coolant but the oil was Odd Colored so i rather error on the side of caution i mean the jeep is 30 years old. When i tore it down i noticed that 1/2 the gaskets on the way to the head were bad anyway. Also When i removed the Head Bolts the front bolt on #1 Cylinder was badly rusted. I wonder if this could have caused problems. Also the head gasket was rusted at that bolt hole. The Head and Exhaust ports are Caked in Carbon From 30 years of stop and go driving. I guess even if the head gasket wasn't bad It's a good oppurtunity to go in and clean it all up. I don't really mind the Head set is only $50 I am goign to take te head in and get it pressure tested and surfaced. I am wondering if its worth me putting the Valve stem seals in and lapping the valve seats. My only concern is that by doing so i may wipe the piston rings out. On the Other hand the Amount Of Carbon build up on the top of the combustion chamer was so thick it maybe have been under higher then normal compression. In the Future i will run a compression test.
