M-4000-M8S diff cooler

[Jmk]

I've recently spoke to Mike at ford performance about the diff cooler for 15/16 base/tech cars. He told me about the kit ford has put together. The description on ford site is vague at best. Did anyone purchase this kit? Any first impressions/insights/pics that could be shared. It's kind of pricey at $2400 but if it's plug and play I might bite. Thanks for any info

I have it in my 2016 Tech Pack. You either need to have a good speed shop install it or have a lift. The most difficult part is replacing the diff cover and this requires partial rear suspension disassembly in order to remove the half shafts so that you can drop the diff. The second most difficult part is installing the cable harness.

Once installed it works great but you don't get the temperature reading on the info screen like on the Track Pack and R.

Mike sold me my kit for $1650.

You can use the existing differential cover, make your pump pickup from the drain port and pump into the fill port. I added an aftermarket pump and connected to the existing cover in this way and it works great. I need to note that all of my diff cooler components are aftermarket, I also added an aftermarket temperature gauge with the thermocouple mounted in the factory location. There are a few options to make a good aftermarket system on the 2016 cars.

I bought the kit and just finished the install today. The nice thing about the kit is it looks OEM when it's installed. If you have the ability, going with aftermarket parts like [MENTION=20343]GT_Dave[/MENTION] did is probably better in my opinion. I did end up modifying a few things with the kit that didn't fit together and my wiring harness had some undersized ring terminals on it. Ford Performance did fix my harness and shipped it back and forth for free, so they were good to work with.

Unfortunately, just like the instructions for the track pack transmission and cooler installs, the instructions say not to duplicate or share. Sorry. I'd love to share them but I don't want to risk potential repercussions with Ford.

That sucks

Would love to see a parts list!

You can still get the instructions with parts list from Ford Performance. No copyright violation needed.

After hitting a roadblock trying to get the halfshafts out, I considered using the stock cover like GT_Dave talks about. I then realized that I would need to drill out and tap the hole where the thermostatic switch goes (this is already done on the replacement cover supplied in the kit). The switch bottoms out in the existing hole (that doesn't go all the way through) in the stock cover. Drilling and tapping means I'm introducing metal chips into the diff so I decided to go all the way and actually replace the cover. I had to put my car back together and take it to a local speed shop to have them complete the job because I just couldn't get the half shafts out.

The temp guage socket in the rear diff cover is designed to be dry...
Good to hear you were able to get the job done!

Getting the half shafts out was the most difficult part of the job for me as well. I had to buy a better crow bar and still it was not easy. I think with the car on a lift it's probably easier to get good leverage.

Tank,

Unfortunately, the thermostatic switch is long and using the cover supplied in the kit, actually is immersed in the diff oil. Therefore you need to either drill out and tap the stock cover or use the new cover.

Dave can you share the details of your install

Thank you Brian. I did not know that. It's a 'wet sensor'? Do you know if it has part number 9L8Z-6G004-E? I haven't got to it yet but plan on getting my diff temp on my dash....
