Question about 2001 Ford Expedition
The heater for my 2001 Ford Expedition (4.6 engine, 2 wheel drive) blows some heat but not much. I just replaced the thermostat and notice that the replaced one was not stuck open (replaced it anyway). Problem still exists. Any ideas? Someone said that the temp gauge needs replacement; however, not sure where it is. Any ideas on any issues or route to tackle? thanks.....
I would flush the whole system with radiater flush then replace with new coolant. But make sure the heater is set to full heat when you flush it ( while driving around the block with flush in it) so the small radiater that has the hot water flowing through it gets flushed too. It may have some build up in it stopping the full flow of heated water/coolant through. If it is bad enough may need to remove and spray out the rubber hoses from the motor to the heater core, and possibly remove the heater core and hose it out to make it flow better and therefore increase the heating ability. Hope this helps.
