Hose ID is 32mm. Stat is 42mm. So am going to try one of these. Stat can be changed when fitted and fits in line.

Failed !! New stat. Short hose off. Plastic pipe corre t diameter to push in. Silicone up. Spent 2 hours and couldn't get the thing in far enough. It needs to be 25 to 30mm clear to allow the T fitting back in. No way was it going. Managed about 10mm but nearly gave myself a hernia!!! What...

Modified mine. Removed fibre board. Made checker plate replacement. Fitted with 4 hex head self tappers into clips on the brackets that held the fibre board. 4 bolts and a lightweight ally sheet comes off.

High pressure pump.can blow vapour into timing cover and hence crankcase and burn it.

7,000 miles on Rears 6.7 Front 6.5 These are lowest measurements across tyre. Interestingly from the centre band. Must check tyre pressures for this size. Started at 32 psi all round.

Gates stat on order. Getting the lube prepared !! Ohh err... Thanks to all for input and help.

Thanks. So for reference the small arrow just above cold on gauge is 50 degrees C. When gauge is at 1/4 reading, so half way to vertical, coolant is 60 degrees C. Drove for an hour and reached 60 degrees in traffic !! Think it's time for hose mod !!

Automatic has a very short top hose from engine then hits a fitting. New thermo may just fit, anyone done it ??

These work well. Originals are 16mm top hole, 32mm bottom hole and 26mm depth. https://www.ebay.co.uk/itm/224001269669?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=zOkNuKe6QJO&sssrc=4429486&ssuid=b5qQSb6hQNK&var=&widget_ver=artemis&media=COPY Or these...

Beware! New arms have crap ball joint covers and it is still worth a poly upgrade for the work involved to re do them !!

Or if joints are good fit poly joint covers. They last longer than the rubber ones.

Many thanks. Wondered which way around it went! Am assuming once the original has failed it won't start working again or won't close permanently.

Thanks. FBH is working fine. Looking at the temp gauge with FBH off, the thermostat in engine has failed open. Never passes 1/4 way.

Am going to pull FBH and see what temp gauge does !!

Possibly. I am surprised that the stat has much part to play when engine fully warmed, but looks like it does. Temp gauge does go up and down at the moment so a working stat works hard on a TD4.

It appears there is nothing that Arctic has not photographed !!

Suggesting that maybe the engine thermostat has failed open??

thanks - or it is working correctly and keeping the coolant up to temperature !! Not had it with any other TD4 and FBH so not sure.

Rave suggests that there is a sensor in the heat exchanger that is used to measure coolant temperature - see extract: The heat exchanger transfers heat generated by combustion to the coolant. A sensor in the heat exchanger provides the ECU with an input of heat exchanger casing temperature...
