Any DIY tips out there on replacing a 2016 LR4 SCV6 Thermostat Housing?

I have a fairly stuck clamp. Worked couple of hours on them with WD-40, zero movement.

Did you lose one of the lower metal clamps to get the thermostat with the lower radiator clamp out first and then separating them outside the car?

I was contemplating putting the thermostat back and try pushing from the top with a flathead, but get a good angle seems impossible. I just can't seam to find a good position to put force on them.

There's a metal retaining clip that holds the plastic coupling to the lower thermostat, just pop it out with a flat head screwdriver. With the thermostat bolted down in place, I used a single paracord and tied constrictor knot around the top side of the lower tube and with the other end another constrictor knot on the opposite side. This leaves a loop hanging just below the bottom of the frame, and I used my breaker bar for leverage pulling down on the paracord's loop. The constrictor knots on each side evenly pulls the pipe out of the thermostat.

In my case, the adapter on the bottom of the thermostat did not come off and I needed to purchase the entire hose assembly that goes from the thermostat down to the radiator, that hose assembly was about $250.

It's a standard brutal plumbing problem, just 2 little tips, there is a T-30 bolt that attaches the thermostat to the body, best way to get to that is several feet of extensions placing the socket wrench up at the fender rather than down in there.
And when you get the entire lower hose assembly, check from underneath to be sure you have contained all the bits and bobs in that provided retaining zippy tie, otherwise you can have things rubbing on the serpentine belt if not properly secured.

Here is my video for that entire project.
Skip to 44:37 for the bit about the thermostat and watch to 50:45

Yes, that's it. The part number is also in the video in the beginning in the parts list.

If you can actually get that old thermostat/hose bit please let us all know how!

I replaced the entire lower hose, no sense spending the money and then not replacing.

Note that Rover hoses come with the camps pre-positioned and locked open, that is very helpful.

Depending on your schedule you could try to take it apart and then purchase only if necessary.

I see AB is $150 and I paid, as I recall $250 at the dealership, but then I did not have time to wait and the dealership is literally 2 miles from my place...

Just a quick note about AB, if you are clicking around too fast it is easy to mistakenly purchase after-markets rather than genuine Rover parts.
Always double check !

txfromwi,
I really appreciate your step-by-step video and you meticulous attention to detail. I referred to it often as I replaced my thermostat. What did you do about the small zipties attached to christmas-tree fasteners? I had to cut several. The air-filter box mounted fasteners are not reusable. Thanks for any help.

The part numbers for Christmas tree zip ties are in the video - you probably caught a nap in that bit!

I make videos so I never need to figure it out again - I hope to keep these vehicles until I do my final check out.

I'm glad you find it useful!
