Frequently Asked Questions
Will this install with the factory hoses and fittings?
Yes — this radiator uses OE connection points and hose sizes. Your existing transmission cooler lines will bolt up directly without adapters.
Do I need any gaskets or seals before installation?
The radiator core itself is sealed, but you'll want to inspect the mounting gasket and line connections for wear before reinstalling. Grab a new transmission cooler line gasket kit if your existing seals show age.
What's the return process if it doesn't fit or arrives damaged?
Contact our support team with photos if there's a fit issue or damage — we handle warranty claims directly from our Florida warehouse and process replacements or refunds based on the condition of the unit.
