    Tank, overflow, polished stainless, 3" x 10", includes cap and bracketry

    This is the overflow tank we reach for when doing a conversion in pretty much any Jeep. We love the stainless steel construction, simplicty and ease of mounting. They take up little room and can tuck into a variety of locations. It will outlast all of those cheap plastic ones from the factory.

    Installation Requirements

    Fan clearance

    Typical mechanics hand tools along with the appropriate hoses, clamps and coolant required with a normal radiator swap. After installing this upgrade radiator, we recommend that the installer should verify fan-to-radiator clearance and engine mount integrity before operating the Jeep.

    Radiator Warranty Policy

    Our radiators come with a 1-year / 100% warranty for defects in materials or workmanship, which is prorated and Novak will cover the cost as follows:

    • 1 year, 100%
    • 2 years, 75%
    • 3 years, 50%
    • 4 years, 25%

    The above does not include incoming shipping of your radiator to Novak.

    Coverage can be denied if it is determined that:

    • Abuse has occured; no radiator can withstand shoddy installation or debris striking the radiator
    • Electrolysis has occurred due to failure to ground the radiator to the frame
    • Overpressured. We do not recommend exceeding 16psi on the cap

    Our overall warranty and other policies are found here. We strongly recommend you educate yourself about cooling and the related topics here before taking on this or any custom vehicle cooling project.
