Bullet Proof Diesel 90201157 Heavy-Duty Oil Cooler Upgrade with Gaskets

Keep your 6.7L Powerstroke running cooler under load with this heavy-duty oil cooler upgrade from Bullet Proof Diesel. This larger-than-stock cooler replaces the OEM HC3Z6A642A unit and delivers improved cooling capacity when towing, hauling, or driving in hot conditions.

The upgraded design uses a greater surface area and additional heat-exchanger layers for approximately 10% better heat transfer. Larger coolant passages also help reduce the chance of clogging from debris, supporting longer cooler life.

Key Features

• Heavy-duty construction, larger than the factory oil cooler
• Direct-fit replacement for 2011–2019 Ford 6.7L Powerstroke
• Includes gaskets for installation
• Improved heat transfer and larger coolant passages
• Straightforward bolt-on upgrade

Benefits

Many owners report noticeably lower oil temperatures (often 10–15°F or more) during heavy towing or hot-weather use. The extra cooling capacity helps protect the engine when the stock cooler is working hard.

Fitment

Fits 2011–2019 Ford Super Duty trucks with the 6.7L Powerstroke diesel (F-250, F-350, and similar applications). Confirm compatibility with your specific truck, especially F-450/F-550 models.

Note: If your truck has a lift/level kit or other steering/suspension modifications, check for possible interference between the front driveshaft and the cooler. External damage from such interference is not covered by warranty.

What’s Included

• Heavy-duty oil cooler
• Gaskets

Warranty: 1-year parts-only limited warranty.
