Will the transmission cooler lines connect directly to my existing fittings?

Yes — this is an OEM radiator built for automatic transmission models, so the cooler lines match factory port sizes and thread patterns. Your existing hoses will bolt on without adapters.

Do I need to flush the cooling system before installation?

Flushing is always smart before dropping in a new radiator, especially if your old core was corroded or full of scale. Use distilled water and a flush kit to clear the block and hoses, then refill with OEM coolant and bleed air from the system per the service manual.

What's the return window if the radiator doesn't seal properly?

Contact customer service with photos of any leaks — returns are handled on a case-by-case basis. Inspect the core and fittings immediately upon arrival and document any visible damage before installation to protect your return eligibility.
