Title: Heater not working!
Post by: Chief on January 27, 2005, 06:16:37 AM

OK, here's the deal. Truck warms up to normal operating temp, and I turn the heat on, full blast. Nice and warm for about 20 secs, then blowing BARELY warm air/cold air.

So what's the deal? Heater core blocked up or what???

Heater hose collapsing?

An easy way to clean out the heater core is to disconnect both heater hoses and flush the whole thing with a garden hose.  Low pressure and low volume shouldn't damage the heater core even if it is a little weak.

I'm beginning to think I have
a blocked or plugged with dirt
heater core, it blows warm, but
I changed the thermostat back
to the stock 180, and it didn't
blow as hot as it used to  :(

How bad is it to open up and
pull that critter out ???

Possible. When I drain coolant to clean the core, I'm poppin a new one in.
