Is your radiator really leaking? Surge tanks, and the components associated with them, are prone to failure. A leak in one of these components in applications where the tank mounts above or alongside the radiator can easily look like a radiator leak from the coolant dripping down onto the radiator. 

Perceived Leaking Radiators with surge tanks in these positions, regardless of plastic or metal construction, must have the tank and hoses inspected before determining the radiator to be defective, or at fault.

All radiators returned under warranty are checked and tested. If no leaks are found, credit will not be given. 

Please feel free to contact your Northern Radiator representative with any questions regarding this topic.
