Warning: Installation of accessories should only be undertaken by those with mechanical knowledge and are familiar with working on
vehicles. Always use eye protection (goggles, safety glasses or shield). Park the vehicle in a well lit area, on level ground and apply the
parking brake. Only work on a cold vehicle that has been sitting overnight, failure to do so will result in severe burns and injury. Before starting
the vehicle, make sure no tools or any other items are left under hood that could interfere with or be drawn into moving parts of the engine.
Failure to follow instructions can lead to severe damage and personal injury.

INSTALLATION CONTINUED
Locate Transmission Lines
Hose Connections
Note:
1. Find the two transmission oil lines that run from the transmission to the
radiator, usually steel lines connected to the bottom radiator tank or on
a cross-flow radiator the passenger side tank.
2. We recommend using the cooler in series with the factory radiator cooler.
To do this you need to determine the return line to the transmission. Warm
up vehicle & feel the trans lines, the colder of the two lines will be the
return line.
1. Disconnect the return transmission cooler line from the radiator.
2. Take the supplied Insta-dapt Adapter fitting and install onto radiator using
the appropriate Male or Female end.
The Insta-dapt fitting has a 1/2”-20 Thread and fits most vehicles
with 5/16” transmission cooler lines. For vehicles that are not compatible
with the Insta-dapt Adapter, please reference the Radiator Adapter Fitting
Guide included or go to www.derale.com for alternative radiator fitting
options.
3. Carefully route the looped hose now attached to the cooler to the
Insta-dapt Adapter now connected to the radiator. (See diagram #5 & 6)
4. Using the supplied Hose Clamp, cut hose and attach to the Insta-dapt
Adapter.

5. Route the remaining hose to the disconnected transmission line and cut hose to length.
6. Using the supplied Hose Clamp, attach and tighten.
When routing hoses, be sure to keep all hoses away from sharp edges, moving parts and hot engine components.
Hoses should be routed carefully and should not be bent in less than a 3” radius.
A kinked hose will restrict flow and could cause transmission failure.
