Frequently Asked Questions
Does This Oil Cooler Require Modifications to the Stock Mounting Brackets?
No, it does not require modifications to stock mounting brackets; the direct-fit design preserves mounting options and promotes installation ease, allowing straightforward replacement with included hardware, seals, and components for a leak-free, reliable setup.
Can the Mmoc-F2d-03 Be Used With Aftermarket Oil Filters?
Yes. He notes aftermarket compatibility is generally fine; the unit accepts common oil filter options that match Ford 6.0L specifications. Proper thread size and filter clearance should be confirmed to guarantee leak-free fit and performance.
What Is the Warranty Coverage and How Long Does It Last?
Mishimoto provides warranty details covering defects in materials and workmanship; the coverage length is typically limited lifetime for the oil cooler itself, with specific terms, exclusions, and registration requirements detailed in the company’s warranty policy.
Are There Torque Specs Included for Installation Hardware?
Yes — though some may doubt completeness, the package provides installation guidance and explicit torque requirements for hardware; the detached reviewer notes torque specs accompany seals, O-rings, and cooler mounting to guarantee correct, leak-free assembly.
Is This Cooler Compatible With 6.0l Powerstroke Trucks With Lift Kits?
Yes, it is compatible with 6.0L Powerstroke trucks; the responder notes compatibility concerns are minimal. Lift kit effects rarely impact fitment, though verifying clearance and hose routing on raised suspensions is advised prior to installation.
