Thought I'd wait till a really cold day to fit the new thermostat.....job done, fingers just thawing out! :) I shouldn't grumble too much though - I was only holding the torch for my mate! :lol:

What a pig of a job. The instructions, like they always do, made it look simple, but there's not much room down there and, of course, none of the pipes had been off since the car was new, so they were all well baked-on! The hardest one to get off was the one at the back near the temp sensor, the one shown by the red arrow. The yellow arrow shows a little plastic tang that a spring clip sits behind, not mentioned in the instructions and only spotted by looking at the new thermostat trying to work out why the pipe wouldn't pull off! Great fun. :evil:

My mate drained the coolant at the start, reckoning it would save spilling it all over the side of the engine. He checked it for 'strength' too - still good for Siberian temps apparently! Anyway, reassembly only took 15 mins, as opposed to an hour or more taking it off. Started up, let it tickover, opened the bleed valve on the thermostat, all good - took it for a drive, 3 bars on temp gauge showing very quickly, 4 bars when parked up on tickover, and (I think) I can hear the fan cutting in when stationary too....and a red-hot heater again! =D>

I took this screenshot about my X7 136HP hdi data on the motorway. In my opinion the 77 degree is not enough warm. What do you think?

This is very interesting, my 2.0HDi seems to be running quite cool in this weather, I was hoping to be able to just replace the thermostat itself for a 90-degree version, not the entire housing.

So, do we think that the original thermostat has just become slack over time?

Probably yes.

Do you think the thermostat house is dismantlable?

I find only complete thermostat house at the dealers.

Looking inside the housing, you can see what looks like a 'traditional' sort of thermostat. When my mate changed mine, it didn't look as if the old one could be taken apart - I might be wrong, but the plastic parts seem to be welded together, meaning that attempting to strip it down would break the housing.
