Do I need to drain the entire cooling system to install this?

Yes. Plan to drain coolant into a clean container, disconnect upper and lower hoses, unbolt the radiator from its frame, and reverse the process. Refer to your vehicle's service manual for torque specs and coolant refill capacity.

Will this fit my van without any modifications?

This radiator uses factory mounting points and connection locations. It's designed as a direct replacement, but test-fit before closing everything up to confirm clearance in your specific vehicle condition.

What if the radiator leaks or fails shortly after installation?

Contact ModSupply customer service with photos of the failure point and installation date. Each radiator ships pressure-tested, so document the condition upon arrival in case a claim is needed.
