Frequently Asked Questions
Will I need new coolant hoses when I install this?
The radiator uses factory connection points, so your existing hoses will fit. Inspect them for cracks or soft spots while you have the radiator out—if they look worn, swap them now rather than later.
Do I need to flush the cooling system before installing the new radiator?
Yes. Old coolant can carry sediment that clogs a fresh radiator. Flush the system, install the new core, and refill with fresh coolant to protect your investment and get proper heat transfer.
What if the radiator leaks after I install it?
Contact ModSupply with photos and proof of purchase. Defective units are replaced—just make sure all mounting bolts are tight and hose clamps are secure before you assume it's a factory flaw.
