We're going to show you how to drop the oil temps of your JK Wrangler.

If you're looking to keep your 3.8 liter Jeep Wrangler engine cooler today we're going to be installing this Mishimoto Oil Cooler onto our 2008 JK Wrangler.

This Mishimoto Oil Cooler is going to fit all 2007 to 2011 JK Wranglers equipped from the factory with a 3.8 liter engine. This is going to dramatically reduce the engine temperatures by reducing the oil in your engine. It simply attaches with all the included hardware, includes braided lines and a TIG welded aluminum oil cooler. With that said, let's get it installed on our 2008 Wrangler which is already equipped with some Mishimoto products and see how much it lowers that temp.

Tools you need for this installation: 8 millimeter socket, 10 millimeter socket, 27 millimeter socket, 3/8th inch ratchet, trim removal tool, 10 millimeter box wrench and a 1 inch box wrench.

Now to be safe with this installation make sure that you disconnect your battery first. I use a 10 millimeter socket to get our negative terminal off. We've got our hood up, and now the first step is to get your grill off. We have an aftermarket hood, but you're going to remove the six push pins on top by using a trim removal tool, make sure you hold on to them. With all of them removed just go ahead and pull off the grill. We want to pull it straight forward and get those clips detached. Just set it out of the way. Go ahead and remove your air box. Now, you're going to do so by loosening the clamp on the throttle body there, as well as removing that electrical connection. Pull the red safety tab back and the black part underneath and it'll disconnect. Then you use an 8 millimeter socket, or a flathead to get this loosened up. With the clamp off pull up on the air box and it'll pull right out. Make sure you remove that PCV hose, it falls off, you just set this aside.

As you can see we've got our Jeep up in the air. You can do this while it's on the ground, the only difference is you're going to go from the top down through, grab your oil filter and remove it. Now, I would plan to do this the same time that you're going to do an oil change. That way you can replace all the oil, drain it at the same time and get a new filter on there. It'll work out a lot easier for you guys.

Start by removing your oil filter by twisting it counter-clockwise. I'm going to let some of this oil drain out, that way it doesn't go everywhere. Make sure you have an oil pan or something to clean it up. Now we're going to put this sandwich plate into place by putting that rubber gasket end towards the engine using this piece of hardware here. From what I'm seeing, this is about the orientation that you're going to want it. This is a 27 millimeter socket, and they want you to torque it down to 35 foot pounds. So I'll go grab that, get that torqued down. Find a 27 millimeter socket, get this nice and tight. Grab the included banjo bolt, get them tightened down. Might be a little bit hard to grab that thread at first. But you'll get it. We're not going to tighten these all the way down yet. Still leave them a little bit loose, that way we can get both sides in and started and snugged up.

Either re-install your old filter or go ahead and grab a new one and thread it on. Make sure you oil up that seal in the back. Then just get it nice and hand tight. What we're going to do is attach the 45 degree ends to these banjo bolts. You're going to have to find the threads and just twist these on lightly by hand. We're going to with a wrench, get them all tightened up. It also has banjo bolts, but as you can see I've ran them up through here right next to the radiator hose. They're going to pop out right here. They run right along the radiator hose and they're going to pop out right next to the radiator. You can see we've got both of the 45 degree angled ends right here and we're going to do some assembly on that oil cooler before we can get it mounted up.

We've got the oil cooler on the table. This is the back side, it's going to be facing the radiator. This is the bottom right here, and this is the top. Now you're going to grab this specific bracket, you can see there's two slotted holes right here, and set it on the outside. Use the included silver hardware, put one there, then one at the top. The other bracket goes up here, and it's going to face like so, so you can put a pushpin through it. Put the hardware through the outside. Now we can go back and tighten them all down with a 10 millimeter socket and ratchet.

We've got it in the proper location. Now as you can see the brackets overhang over this radiator support down here. And up top it's going to match up with that hole so we can put a pushpin. Now, underneath we're actually going to put a bracket that clamps these two down. What we have to do is put the bolt in the bracket so let's do that. Grab this bracket and the included hardware. Slide it underneath. Just take the bolts, and run them through. Repeat the same process over here. Get them tighten downed with the 10 millimeter socket.

This top section is going to get a pushpin. It'll go right through and we can get the hoses attached. Doesn't really matter which side they go on. This is a universal cooler. So you can just go ahead and put them on either side. Go ahead and get these nice and snugged up. We're going to go back and make a final check on everything before we fully put that grill back on. That way we can get them all tight. Use a 1 inch box wrench to get them tightened up and we'll go back underneath, get all those tightened as well. We have to go crazy on these to get them nice and snug. We'll check for oil leaks once everything's properly all put together.

Re-install your factory air box. Tighten down the hose clamp right up here with your 8 millimeter socket. Reconnect this sensor here. Then depress on this red safety tab. Put in your grill and your installs complete.

We just wrapped up the installation of this Mishimoto Oil Cooler on our 2008 JK Wrangler. Now, hopefully this oil cooler will decrease the temperature on our engine, make it last a little bit longer and increase the longevity of our oil life span. Now you can find this oil cooler as well as a large line of Mishimoto products for your Jeep right here at CJPonyParts.com.
