No heat after 5 minutes... Looking for some help.
I have a 97 f150 xlt 2wd with 69,000 miles 4.2 I have not had a chance to look in to it yet, but the last 2 days on my way to work I lost my heat. Ii have heat as soon as the truck warms up, but drive it 5 minutes and it starts to blow cold. any ideas? Just thought I would toss it out here before I go tearing in to it.
thanks

He might have a leaky headgasket issue... but theres a slight chance that might be the cause.
I am thinking along the lines of a thermostat gone bad or something clogging the heater core.
Now if it had a leaky headgasket, check the coolant for oil. Now if there is oil mixed with the coolant, it might be messing up the thermostat or clogging the heater core.

Not even sound advice? That's better advice than you have given here.
The hydrolocks were due to intake manifold gaskets, not head gaskets. There never was a recall, just an improved gasket set. Engines built before 1/15/08 were affected.

Does the temp gauge go to hot when the cold air comes out, then drop back down when the heat comes back? If so, you are losing coolant. Most likely from the intake gaskets. Look and see if the passenger gasket is a yellow color and the driver's side is black. If you have the yellow one, replace the lower intake gaskets NOW! You are at the mileage where these things go bad. Get parts from Ford only. Also replace both the IMRC bushings at the same time.
