Question about 1994 Dodge Grand Caravan
I have installed a new thermostat but still not getting any heat.
Pretty common on those. I used CLR and disconnected my heater hoses & with a small pump, I ran CLR only, through the heater core, and let it sit in there overnight, flushed it through again next day, back flush as well. re-connect hoses, run engine with heater on, and rad cap off until the rad fan comes on 2 or 3 times, then put cap back on, to bleed air out of system. Cleaned it out enough to get the heat flowing again. If you changed thermostat and didn't let it run with heat on, and rad cap off for a while as described above, then do that first, just to make sure you haven't just got an air lock in the system.
