i got my 5L TUNED UP at the ford dealer and i noticed after driving it for a few miles i had no heat the car should have heat coming out after 5 km or more. the temp guage says it fine in the NORMAL area. they did put a new themostate in. what do you think could be the problem

 

Maybe an air lock or something?

 

hope it's minor, good luck

 

Could be air...

Or the retards put it in upside down...

 

^ what he said!! Or could just be a faulty part...it happens.

 

I agree with the above.

 

thanks guys i found out the problem it was the dial for the heat itself it was stripped and would not turn all the way went to junk yard and got another one now its perfect thanks for the help

 

It always seems to be those little things that we wouldn't suspect LOL!Glad you figured it out.
