This Is How to Install Your 6.0 Trans Cooler- My Detailed Write-UP

Haven't Posted over hear in a while, but here is a write up for everyone.

6.0 Trans Cooler Install on 7.3 Superduty.

I decided to make a detailed write up on my 6.0 Trans Cooler install. This is being performed on a vehicle with a water/oil trans cooler in the radiator. For those truck that don't have that cooler the install will be very similar, the routing of the new lines will be slightly different.

Here Goes.

Start by removing the Top rubber protector from new the radiator support. A door panel tool works great for doing this.


Next Remove the hood latch, this is needed because the 6.0 Trans cooler will not fix in without removing the latch, the 7.3 cooler will however come out with the latch in place.


Next remove the bolts on the upper supports for the AC Condenser, this will give you a little more room to play with, but is not 100 percent necessary.


Next Remove the Grill, this is very simple and will make the job much easier in getting to the top mounting bolts for the cooler. Remove the top screws that hold the upper part of the grill in place and then unclip the lower tabs that hold the grill on, a screw driver with a little persuasion is often needed. Here are the lower clips.


Now you can access the top mounting bolt for the cooler with an extension and a swivel, remove both bolts.


Next underneath the truck/cooler remove the rubber protector out of the way to access the bottom bolts, remove them.


Now find the original 3/8 lines that go back toward the trans, they are located near the passenger side tire.

Hear.


And Hear


Note that these lines are held in place by a plastic clip on the frame, remove them from the clip. Take note which is the upper and lower one coming from which side of the orginal cooler, you will be installing them in the same orientation with the new cooler


Next remove the clips that hold the rubber 3/8 lines to the hard lines and pull the lines back toward the cooler so everything can be removed, then remove the old cooler with the lines, you will be reusing the 3/8 lines later so save them. Note the lower hard line will continue to leak but not much, I lost only about 1/2 quart of ATF during one hour of the line being off.

Next Prep the 6.0 Trans cooler with 1/2 in Trans line, the easiest place to find it is at NAPA, they sell section in 3 ft which is perfect for this install, you can also get a 25ft roll but it is not necessary. Install hose clamps at the fitting on the cooler.


Install the new cooler in place, it can only go one way, with the 90 degree taps on the lower brackets facing the engine. Route the new 1/2 in lines as you go.

Reinstall the bolt on the new cooler, note the lower bolts will need an added washer due to the large hole in the lower bracket.


Next get ready to splice the 1/2 in lines to the original 3/8 lines. The fittings I used are the ones you see below. You will not find these at any automotive shop, home depot, hardware store, etc. They are hard to come by, they are a Barbed Reducing Union 1/2 to 3/8, this makes for no threaded connections in your splicing. You can find them here.
Brass Barb Fittings - PlumbingStore.com


Next Route Your 1/2 lines back toward where the original hard lines are, I found the most logical place to be under the passenger side cooler fitting shown here.


Next cut to fit the 1/2 lines and the original 3/8 rubber lines so that they are spliced together using the fittings, use hose clamps or the original clamps on the connections, make sure all the hoses are not kinked, install wire loom around all hoses is also a good idea. The final results looked something like this.

Driver Side Cooler Fitting


And a view of the splices, note the lines have some slack in them and there are not kinks, also zip tie the lines as needed to hold them in place, this view does not show the upper hose connection, but the hose of the right goes up toward the upper hard line and connects to it.


Next check everything for tightness, install everything you took off. And Start the truck for 20-30 or so seconds, this will fill the new cooler. Check the fluid level and add as necessary, I added about 2- 2 1/2 Quarts of trans fluid.

Drive the Truck and get it up to temp, mine only went up to 130 or so, check the level again and add if necessary, also check for leaks.

Enjoy Your new Cooler.

Nice write up, I did the 6.0 cooler install back in 2003 when the 6.0's first came out. I had a source to get brand new Ford 6.0 coolers for $60 each!! Of course that is before it was the "Mod to Do" the only thing I would add is to place a rag over the top of the AC condensor or your arm will look like it got in a cat fight!! Also I like to get rid of all the spring clip fastners and replace them with good quality hose clamps. You'll love the 6.0 cooler, my temps dropped 40 degrees and I don't have the OTW cooler.

If you're looking for prices on them, I really think ebay is the way to go, it didn't get a steal at 200 shipped to my door but I didn't pay an outrageous price either, keep an eye out on ebay and you can snag one.

Hey...is the FORD with tracks in you avatar yours? I'd like to see some pics of that!

I have my late father's 1966 Ford 2000 3 cyl. gasser. Doesn't get used much here in the woods!

I have a 1990 New Holland Skidsteer with steel tracks. Less than 900 hours on her!
