Do I need to flush the cooling system before installing this radiator?

Yes. Drain the old coolant completely and flush the system with distilled water to remove debris and sediment. Refill with fresh coolant to OEM specification after installation. This prevents contamination and ensures proper heat transfer.

Will this radiator fit without any modifications to my engine bay?

It mounts at the factory attachment points with no drilling, cutting, or bracket work needed. Check that your hoses and transmission cooler lines still reach the new core before final tightening.

What's your return policy if the radiator leaks after installation?

Contact ModSupply customer service with photos and details of the leak. We'll evaluate the cause and work with you on the next step. Most radiator issues are caught during our in-house quality check before shipment.
