Frequently Asked Questions

Do I need to flush the cooling system before installation?

Yes. Drain the old coolant completely and flush the block and hoses to remove sediment. Refill with fresh coolant rated for your vehicle mixing old and new reduces heat transfer efficiency.

Are the transmission cooler lines the same as my original?

This radiator is configured for automatic transmission cooling. Verify your hose sizes and line routing match the factory layout before final assembly some manual conversions may require adapter lines.

What tools and hardware do I need to install this?

Basic hand tools: wrenches, socket set, coolant drain pan, and hose clamps (if reusing original hoses). Mounting hardware and hose clamps are not included use OEM fasteners to match original torque specs. Refer to your service manual for bolt sequence.
