Part: 7.3 Ford OEM Cylinder Head Freeze plug

Part Number: F1TZ6026A

Manufacturer: Ford

Description:

The OEM Cylinder Head Freeze Plug for the Ford 7.3L Powerstroke Diesel engine is a crucial component in the engine’s cooling system, designed to seal off the coolant passages within the cylinder head while also providing a built-in safeguard against freeze-related damage. Also known as expansion plugs or core plugs, these parts play a dual role: they help maintain a sealed coolant system under normal operating conditions, and they provide a pressure relief point in the event that coolant freezes and expands—helping to prevent the cylinder head from cracking.

In a 7.3L Powerstroke, where proper engine temperature regulation is essential for both performance and longevity, a compromised or leaking freeze plug can lead to serious issues. Coolant loss, overheating, and internal corrosion can all result from a faulty plug. These problems are especially dangerous in colder climates, where frozen coolant can exert extreme pressure inside the engine block or head if not adequately protected by functional freeze plugs.

Whether you’re performing a top-end refresh or prepping your Powerstroke for the winter months, the OEM Cylinder Head Freeze Plug offers peace of mind by protecting your engine’s vital cooling passages and structural integrity. Seal it right the first time—keep your 7.3L running cool and protected with a genuine OEM freeze plug designed to do the job for the long haul.
