Greased O-Rings for Ford DR3Z8566A (DR3Z8566B) & 2x BC3Z8590F, GUARANTEED FIT!
**We suggest replacing all the O-rings in this system at the same time since the others tend to fail soon after the first one****We stock all of the O-rings in our listings****Message anytime for installation tips**
Includes three O-rings:
*One O-ring used in Ford part # DR3Z8566A (DR3Z8566B) "T-Connector" where it connects to the thermostat and water pump. This O-Ring is not available from Ford but is easily replaceable. (see pic, circled in green)
*Two O-rings used in upper and lower radiator hose quick connectors. Replaces Ford part # BC3Z-8590-F (see pic, circled in purple)
The O-rings in these coolant quick connectors become flattened over time and must be replaced. It is a very common issue.
**The O-ring will arrive pre-greased with 100% silicone grease which is required for installation**
