Has anyone changed one of these?

Ok so whilst checking a top egr blanking plate as it was not tight I noticed a bit of coolant. Now discovered what it is, coolant thermostat housing, see pic. Wondering if anyone has changed one and the procedure. Thanks.

most disco owners have changed these Rolling with laughter

fairly easy to change,
the only silly thing is that the rear seal to the cooler isn't supplied with it and not easy to track down

Ok. Thanks to all. I presume I rings from local motor factors will do. Also do I need to drain down the coolant or not. Thanks.

Hiya

Oh wow, the cost of them for just 1 x O ring

Looked at the link that @sea raider kindly linked to and also see that @SteveNorman mentions the part number Citroen/Peugeot, part number 198171

https://www.disco3.co.uk/forum/water-conne...ght=O+ring

So looked on here , £6.71 each

https://www.autodoc.co.uk/bosch/707688

I then looked at the other part number and went through them one by one

OEM reference number(s) comparable with the original spare part number
OEN 1981 71 — CITROËN
OEN 1665178 — FORD
OEN W 700100 S300 — FORD
OEN 1981 71 — PEUGEOT

The Ford part number comes up at £1.30 each , alas seller is away till 20/1/22

https://www.ebay.co.uk/itm/224711867153?ha...SwVYBgabq0

Hope that helps and also that I’ve crossed matched them correctly in order to save u some money
