Novak Conversions K-XJ11H KryoFlow HD Radiator for 87-01 Jeep Cherokee XJ & MJ with GM Gen I-II V-8 Engine

Quadratec Part #: 12521.1904
Novak Conversions Part #: K-XJ11H

Novak's KryoFlow XJ Cherokee radiators are the final word in cooling for these Jeeps. Their all-aluminum construction and thick, 2 rows x 1-1/4" cross-flow core will shed heat faster than any XJ radiator we've ever encountered.

Note: For the 1984-96 Jeep Cherokee that currently feature the remote fill pressure bottle, this new radiator will convert to a significantly improved system that places the filler neck in the upper radiator hose. The engine bay will be less cluttered and there is less risk of engine damage due to due to air pockets inherent to the complexity and design flaws of the earlier models. Giving a more reliable cooling system.

Modification Required: These assemblies are designed to fit the 1987-2001 XJ & MJ models with engine conversions. The 1984-86 XJ feature a grill support assembly that will not work with this radiator (nor V8 engine conversions, for that matter) and will require that the installer fit the later style grille/radiator support from a salvage Cherokee for this radiator and the conversion to succeed.


This radiator is intended for conversion engines, including the classic Chevrolet Small Block V8's
Every radiator is rated at Heavy Duty to take maximum advantage of the Cherokee's narrow nose and subsequent limited airflow. The radiator features an integrated heat exchanger to cool either your engine oil, or your transmission fluid, according to your choice upon installation.
