hey,

I have a 01 f150 supercrew larait, 5.4 v8. I think the heater core is going out. The heater will work but it sure takes a while to get warm, and once it is warm it is not really hot air blowing out. I was wondering if anyone has replaced there own heater core? If so how hard was it?

 

id check out the thermostat b4 u dive into a heater core.. its not really a small job.. u have to pull the whole dash out..

 

what thermostat? where is it located

 

its not the thermostat for the engine tempature correct? that wouldnt make since to me..must be a thermostat in the hvac system

 

It is the same!
