Hey guys, newby by necessity here. I have a 1999 Jeep GC with I6. I lost heat a while back and learned how to replace thermostat from YouTube. All was well for two months. Last night on the way home, no heat and the low coolant came on. Reservoir was bone dry. I added coolant. When I got to work I noticed a small pool of antifreeze where I normally park which pooled under the radiator. I thought maybe I hosed up the gasket installation. When i got home,the reservoir was dry again. I added water, brought the engine up to temp (190), the thermostat opened..but no leaks. No drips...nothing. I let it run for maybe 10 minutes. Reservoir is dry again. Where could the coolant be going? I mean clearly there was a leak. It's not redlining, temp never goes above 220/230. Heater core maybe?
Obviously, I'm not a mechanic but can't afford one right now either. Any suggestions on how to proceed other than driving it off a cliff with me in it?
