Frequently Asked Questions
Everything you need to know about upgrading your 6.0 Powerstroke oil cooler
Is this a direct replacement for my factory oil cooler?
Yes, our oil cooler is designed as a direct bolt-on replacement for the factory unit in all 2003-2007 Ford 6.0L Powerstroke engines. It uses all the original mounting points and connections, requiring no modifications for installation.
What's included in the kit?
The complete kit includes: the aluminum oil cooler assembly, all necessary gaskets and O-rings, installation hardware, and detailed instructions. Everything you need for a professional installation is included in the box.
How difficult is the installation?
The installation is moderately difficult and typically takes 4-6 hours for a skilled DIYer. You'll need to remove the turbocharger and intake manifold to access the oil cooler. We recommend having a service manual and proper tools. If you're not comfortable with this level of work, professional installation is advised.
Will this prevent EGR cooler failure?
While our oil cooler significantly reduces the risk of EGR cooler failure by maintaining proper oil temperatures, we recommend also upgrading the EGR cooler for complete protection. The factory EGR cooler is another known weak point in the 6.0 Powerstroke.
What's your warranty policy?
We offer a 2-year unlimited mileage warranty against defects in materials and workmanship. This doesn't cover damage from improper installation, accidents, or neglect. Proof of purchase is required for warranty claims.
