Speaker: Today on our 2006 Chevrolet Uplander well be installing the Derale transmission cooler kit with barbed inlets part number d13502. Well begin the installation by removing the under carriage air dam. There are four bolts holding it on. After removing it well undo the clips holding the wiring harness here to move it out of the way. You can then see the two transmission oil cooler lines running on the inside of the radiator. Well now move underneath the hood here on top.
Well undo the C clip here to remove our transmission oil cooler line from the radiator. With it removed we can move back underneath the vehicle where well undo the clip bringing our transmission cooler line down to make it easier to cut and add our flare ends. With the line down well cut a chunk using a tubing cutter. With our line cut we can now double flare the ends. You can rent a double flaring tool from a local auto parts store.
Refer to the video on our website on how to double flare if you have any questions. With our ends flared were now ready to put our hose on. Its a good idea to go ahead and wet the inside of the hose down with some transmission fluid. This will help to make it easier for you to get the hose over the flared end on your line. With the hose over the flared end we can then take the hose clamp and slide it over the hose and down to our flared line.
When clamping the hose clamp down you want to make sure youre on the inside of the flare towards the line. Now we can go ahead and clamp the hose clamp down. With that end on we can now go ahead and put the other side on. With our rubber hose now on the transmission line well take the other end that we removed from the radiator and fish it back up to its mounting location. Back under the hood here we can go ahead and reinstall the clip into the fitting before we install the line.
Now that our clip is in place all well need to do is push the line in, securing it to our fitting. With that done well move back underneath the vehicle where we can route our rubber line that well use for our transmission cooler between the radiator and the core support. You may need to bend the core support slightly to avoid crimping your rubber line. Now here in front of our evaporator were ready to mount our transmission cooler. Well first need to dry fit our cooler to make sure that the line is long enough as well as make sure that your cooler will have sufficient air flow. Now that weve dry fitted the cooler well go ahead and cut our line in half and slide our hose clamps on. We can then install the hoses onto the cooler. Again its a good idea to go ahead and wet the hoses down with some transmission fluid just to make it easier to get it onto your cooler. With the hoses on we can go ahead and clamp the hose clamps down, making sure that the flared end of the cooler line is on the inside of the hose clamp. Now that both hoses are connected to the cooler well go ahead and use self-tapping screws to mount the cooler to our core support here. With our cooler mounted we can go ahead and reinstall our wiring harness back onto the core support and then reinstall the air dam. With that well then start the vehicle and check our transmission fluid as well need to add some to compensate for the added space in the cooler. After ensuring that there are no leaks weve completed our installation of part number d13502 the Derale transmission cooler kit with barbed inlets on our 2006 Chevrolet Uplander. .
