Mount the cooler / bracket assembly into place at the lower factory mounting locations with the previously 7.
removed factory bolts. (see Detail A)
Mounting the upper portion, some models may require drilling a 7/32” hole into the support and using the 8.
provided self-tapping screws to mount. Note: Caution!! Do not go ALL the way thru the cooler support; this
could damage the A/C condenser. If this is not required, use the factory bolts for installation.
(see Detail B)
Re-Install temperature sensor: Use the bracket contained in the kit to sandwich between the bolt and the 9.
new cooler bracket in the lower driver’s side. Attach the temp sensor with proper side facing the grill.
Connect cooler line 10. s:
For 4118GMT: Splice into the factory lines coming from the transmission. Use the hoses, barbed reduction
couplers (3/8” to 5/16” hose I.D.), and hose clamps provided in the kit to connect the lines to the new cooler.
For 41186GMT: Splice into the factory lines coming from the transmission. Attach line with 6AN female
fitting (

cooler.
Routing these lines to the passenger side is ideal. Trim hose length as necessary to provide clean fitment.
Use provided nylon tie straps to secure routed hoses. Inspect hoses to be sure no rubbing occurs on sharp
edges.
Note: BE SURE that all moving parts of the engine, cooling fan and transmission cooling line
/ hoses (where applicable) are clear of each other before proceeding!!
We suggest following the vehicle manufacture’s recommended transmission fluid level checking and filling 11.
