Frequently Asked Questions
Will this radiator work with my automatic transmission cooler lines?
Yes — this radiator is engineered for automatic transmission models and includes integrated transmission cooling passages. The cooler lines connect at factory ports without modification.
Do I need to flush the cooling system before installing this?
Drain the old coolant completely and flush the block and hoses to remove debris. Refill with fresh coolant and bleed air from the system per your service manual before running the engine.
What hardware do I need to mount this?
The radiator uses factory mounting brackets and fasteners at the original attachment points. Confirm all mounting hardware is present on your existing brackets before installation — replace any damaged bolts or clips.
Products received may vary slightly from images due to manufacturing tolerances or supply chain variables.
