Problems with your Upper Water Pump neck leaking on your 7.3L Powerstroke??
This is your Fix:
New Thicker O-Ring
Black Powder Coated Stainless Steel Seal Plate
New Longer Bolts
If you own a 7.3L Powerstroke Engine you are probably familiar with the leaky Thermostat housing. The thin metal used to produce them can cause an uneven set when tightened down. The "THFR" was designed to pull down evenly on the factory housing to create an even seal. Built with stainless material then powder coated to give it EXTREME durability for your truck!!This kit works equally well on the 94-97 "OBS" and the 99-03 engines.
