Frequently Asked Questions
Will this fit my cooling system without modifications?
Yes—this radiator mounts directly at factory points. No drilling, welding, or custom brackets. Bolt it straight in where the original sat.
Do I need to drain and flush the system before installation?
Flush your cooling system and replace the coolant as part of the swap. This is standard maintenance and ensures you're not trapping old sediment or corrosion in the new core.
What if the radiator arrives damaged or doesn't function?
Contact ModSupply directly with photos or a description of the issue. Damage claims or performance failures are handled on a case-by-case basis—don't attempt installation on a visibly compromised unit.
