If you standing in front of the truck, the top radiator hose goes to it. Click this link, then click on the link posted, lots of info for you to get to know your motor.

Checked your coolant level lately? Low coolant = no or little heat

I'm having about the same problem with my 04', changed the thermostat, added more antifreeze, added quite a bit and the fluid level never changed. Yet when i'm driving it the gauge reads Hot... and yet still no warm air, and its in the middle of winter lol. So yeah i'd greatly appreciate any help with this forum
