Hey Jeep guys, I had some heat yesterday but last night and today nothing, I've got a slow leak on the radiator, don't have the $ for a new one right now, checked fluid, filled it and ran to town and drove it around to different stores approx 25 miles, temp was right when I left, after I put distilled water and full strength anti freeze in to fill it up ran back home approx 10 miles, temp was low, approx 180 it has the stock195 T stat, no heat. I'm in Mid Lower Michigan 18 degrees cardboard in front of half the radiator. I'm thinking T stat? Or heaven forbid getting a plugged heater core.
Any thoughts would be appreciated, I'm changing the T stat since it's cheap and easy to do.
thanks guys.
