97 f150 xlt 4.6l just replaced thermostat still have no heat

 

heater core is probably clogged.

or do you mean that the engine temp gauge shows colder then normal operating range?

 

temp gage is fine shows proper reading how do you unclog the heater core?

 

usually you get to replace it, which means you get to remove the dash. Its between the firewall and the front face of the dash.

I would take it somewhere and have them look at it tho, dont trust my E-Diagnosis 100% :o

 

thanks for the info will get it checked

 

I have the same problem with my 2000 5.4. Can I use pressure to try to force water through the core?
