thanks, I'll go and see exactly when my father purchased the F150, I know it's a 2009. I'll first check to see if the coolent is flowing thru the core.

I do not trust his Ford dealer. That's my main problem. They've got the New Car market all to themselves, and they know it [when it comes to service] I'm pretty shrewd when it comes to this dealer.

And if it's covered...I'll make sure it's covered.

Thanks!
