Hi all. I have a 99 expy XLT 5.4 4wd 105k with front & rear heat. I get perfect "Hot" heat out of the rear vents. The front vents blow cool. Fan is fine. As I adjust the front heat range from cool to hot, it only goes from cold to luke warm. The radiator is full. Reservoir is full. No major leaks, though I smell Antifreeze quite often when outside the truck. I just added a tube of bar's stop leak last week just to be on the safe side. Still smell antifreeze but dont see leaks. The engine temp runs right in the middle with no "Spikes" and drops. So, i'd say the thermostat is Ok. Any ideas on why the front heat isn't warm?
Thanks!
Thanks!
