Frequently Asked Questions
Will this radiator work with my current hoses and fittings?
OEM radiators are sized and configured to match factory hose connections. Verify your existing hose diameter and inlet/outlet port placement before install. If hoses are cracked or hardened, replace them during the swap — old coolant lines often fail around the same time as the core.
Do I need to flush the cooling system before installation?
Yes. Drain the old coolant completely and flush the block and heater core lines to remove sediment and corrosion buildup. Installing a new radiator into a contaminated system reduces its lifespan and cooling efficiency. Fresh coolant rated for your vehicle is required.
What if the radiator leaks after I install it?
A new radiator should arrive leak-free and pressure-tested. Before you assume a defect, confirm all hose clamps are tight, the radiator cap seals properly, and hose connections are secure. Run the engine and feel for weeping at joints. Leaks almost always come from fittings, not the core itself — tighten everything first.
