NO HEAT 4X2 SUPER CREW 5.4 V8

2001 Ford F-150

I had no heat blower works. I looked under the hood at the reservoir and it was empty so I filled it up and started the truck and I had heat. Can you help? Ok so I keep driving for a week and had to fill the reseroir again.

Normally your mechanic would perform a pressure test to see where the leak is, but when it's this small, it is more effective to add a small bottle of dark purple dye, then search a couple of days later with a black light. The dye will show up as a bright yellow stain that you can follow back to the source. Be sure to check at the inside of the tail pipe. Dye there indicates a leaking cylinder head gasket.
