Complete Performance Thermostat Fix – 7.3L Powerstroke (TF-7.3)
Tired of dealing with a leaking thermostat housing on your 7.3L Powerstroke? You’re not alone. The factory upper water pump neck is notorious for leaking due to thin metal that warps and doesn’t clamp evenly when tightened. This kit is the proven fix.
The Complete Performance Thermostat Fix is designed to evenly distribute clamping force across the factory housing, eliminating leaks for good—whether you’re running an OBS or Super Duty 7.3.
🔥 What’s Included:
-
Thicker upgraded O-ring for improved sealing
-
Black powder-coated stainless steel seal plate for even clamping pressure
-
New longer bolts to properly secure the assembly
💪 Why It Works:
-
Factory housings can flex and seal unevenly
-
This stainless seal plate pulls the housing down evenly
-
Eliminates repeat leaks and coolant seepage
-
Built from stainless steel and powder coated for extreme durability
🚗 Fitment:
-
1994–1997 Ford OBS 7.3L Powerstroke
-
1999–2003 Ford 7.3L Powerstroke
✅ Proven Solution:
If you own a 7.3L, chances are you’ve fought this leak before. The THFR (Thermostat Housing Fix Repair) was engineered to solve it once and for all—no more bandaids, no more coolant mess.
