JEEP RADIATORS
When installing a larger engine into any Jeep vehicle, the radiator is normally an area that needs attention.
We offer conversion radiators for just a few of the Jeep applications. For CJ7 models, we offer a Part No.
716685, which is a 3 row copper/brass radiator. It measures 24-3/4” wide, 20-1/2” high, and 3” thick. For
YJ & TJWranglers, we offer P/N 716687. This is a 3 row copper/brass radiator that measure 20” wide,
22” high, and 2-1/2” thick. Both radiators utilize the factory mounting holes and work well with either the Chevy
V6 & V8 conversions. On early model Jeeps, we recommend having a custom radiator built or your stock radiator
modified.
Mounting a radiator for offroad use is critical due to rough offroad conditions. Be sure you secure your radiator properly, since any
slight damage could cause severe engine overheating problems. The Jeep radiator is normally mounted to the grille area by a flange
that is part of the radiator. This type of mounting keeps the radiator independent of the chassis. On some early Jeep, it may be
necessary to shorten the grille cowling. This will allow for the radiator to be positioned further forward, providing more room for the
new engine.
If an engine-driven fan is going to be used, a fan shroud must be installed. This will allow proper protection
from the rotating fan, but will also create an effective airflow through the radiator for maximum cooling. We
have seen many electric fans used with engine conversions. They are normally mounted directly to the
radiator. They offer great cooling characteristics and come with their own shrouding for safety. Sometimes
they can provide additional clearance for the engine when necessary.
If an automatic transmission is going to be used, you might consider incorporating the transmission cooler
inside the radiator. Since most conversions are limited on space, a separate transmission cooler might not
be feasible.
If you are retaining your stock engine temperature gauge, we suggest that you verify its calibration. The gauge can sometimes read
10-15 degrees different than what the Chevy or Ford engine is actually running.
Our trademark named “Rad-A-Kool” aluminum radiators cover Jeep applica-
tions from 1970 to current Jeep models. On earlier model Jeeps, we recommend
having a custom radiator built or your stock radiator modified.

a Ford or Jeep 6 cylinder radiator are the same as our Chevy radiators.

Our radiators can be ordered with or without a transmission cooler. The radiator has two 1/4" NPT fittings welded into the tank. We
also include two 1/4” Male NPT x 5/16” inverted flare fittings. A benefit of the transmission cooler in the radiator is the heat exchange
between the radiator and the tranny cooler. The radiator brings the transmission fluid up to a safe and constant operating
temperature.
