Direct replacement cooling core for automatic-transmission X3 models. This is a factory OEM radiator engineered to match your vehicle's thermal and pressure requirements. Built to restore stock cooling capacity without modification.
Do I need to flush the cooling system before installing this radiator?
Yes. Run a coolant flush to clear old sediment and debris from the system before dropping in the new core—especially important if the old radiator failed. Fresh fluid helps the new radiator work at full efficiency.
Will this radiator work if I have a manual transmission instead?
This radiator is spec'd for automatic transmission models only. It includes integrated transmission cooler passages designed for automatic gearbox cooling. Manual transmission models use a different core design.
What if the radiator arrives damaged?
Inspect the unit immediately upon delivery. If you spot damage to the tanks, fins, or connection ports, document it with photos and contact ModSupply within 48 hours—we'll handle a replacement or return at no cost to you.
