Installation Requirements

Novak Radiator in a Jeep Wagoneer

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:

  • 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
