2000 wrangler sport i6 5spd 130k. Water pump and radiator replaced less then 3yrs ago
I was driving down the highway yesterday when my heat went ice cold. Knowing what would probably happen next. I pulled over and bam 240 degrees. I can't find a coolant leak. But it's all over the motor, fan, hood etc. I started with checking the radiator. Still had coolant. Checked all the hoses. Seemed like a small blockage in the upper heater core hose because well. The hose is hot at the water pump and cold back by the heater core, so I replaced it.
Now, it isn't overheating (as much . . Running at like 210?) but I still don't have heat?
Any suggestions on where to start looking ? I'm thinking the thermostat is probably stuck closed.
