Today on this 2006 Dodge Grand Caravan we are going to install Derale Transmission Oil Cooler, part number d13502. To start our install we need access behind the grill. So to make things easier and a lot of working room we will go ahead and remove the front bumper cover. Were going to remove these five screws, and also each side is going to be this bolt and plastic grip we have to remove. Now there are some fasteners we have to remove at the fender well here one, two, and three there is one pointing up this way. When finished on the drivers side, lets go to the passengers side and repeat the same process.
Go ahead and get underneath the vehicle and remove the five plastic ribits. Alright now were going to get behind the bumper and disconnect the fog light wiring as well. This little tab right here you just pull back a little bit and it pops apart. Theres one fastener that is located in this area right here, and to get to it we have to remove the headlight, three bolts on top, and then we just disconnect the wiring harness. This little plastic lock right here, you pull up, and then you squeeze it, and it comes apart.
Then if you pull on this tab right here you can rotate this ring, that will also give you access to it, but the bulb will come out too, so kind of be careful there. Theres a nut right here that we have to remove. Alright at this point we can take off the bumper cover, and you definitely want to have an extra set of hands to help you do it. With the top shroud off now we have plenty of room to do our work. Alright now we have a view of where we are going to install.
This is the transmission cooler right here and this is our transmission line. We are going to take one of these lines right here, we will use a tubing cutter and a pressure fitting to make our connections between the two lines and the transmission cooler. Alright to make things easier on the line, were going to remove a line from the radiator here, and theres also a clip on the bottom that we are going to remove as well. You pull this collar back, and theres a wire clip we can pull out. Make sure you dont lose this wire, and then we can remove our line.
Use a tubing cutter to cut the line. The compression fitting that we are going to be using is part number d13032. Alright before I put our pressure fitting together, take a couple of seconds where we put some Teflon tape on the threads. We put tape on the thread side that will go to our barb fitting. Go ahead and tighten these two together. For our line we will slide our compression nut on first then the barrel, run it down as far as possible onto the line, and then tighten it up. And repeat the same process on the other half of the line. Lets go ahead and reinstall our line onto our factory cooler. Now when we install our cooler on top of this cooler, were going to have to get our fasteners behind it, and theres really no room so were going to loosen up the cooler and pull it away. Very simple, just take a screwdriver, twist it and it snaps on each side. When we start work on the transmission cooler we are going to add a line to it, and we are going to put some transmission fluid on there to make it a little easier to slide on. We are also going to slide on a clamp, and we will put it on there and tighten it down. Alright we are going to find a spot for our transmission cooler. You could put it anywhere you want as long as it gets good air flow. So once you have determined that we will go ahead and start installing our fasteners, and the thing works just like a zip tie, just go through the center of it. Thread it on through, then theres a pad that goes between the two coolers, and the adhesive on one side will help keep it in one spot. And go ahead and push it through the other one, and when you have one side done go ahead and do the same thing with the other side. Okay we have two top ones and I have two on the bottom to do the same thing. Now we will take our button and put it on the backside and thread it on in. You dont have to get these super tight just enough to take up slack. The next step is going to be to take a hose and measure the length. This hose right here will go to this fitting. You will actually have to tip it over a little bit, and theres a little bit of extra, and we will cut the hose. Again we will go ahead and dip the hose in transmission fluid to make it easier to push together. We will also slide on another clamp, dont push them together, put it on there and tighten it down. We will go ahead and take our line, again make sure we have plenty of slack and then cut the length. Then we are going to take our line and re-attach it. Take the factory cooler and push it back into position. Lets go ahead and start reassembling the front bumper cover. And there you have it for part number d13502. .
