The Official Extinct Inline Thermostat Mod Thread

Hi Folks,
I had the majority of the cooling system replaced on my 2001 d2 by IE Rovers in Lake Elisornor. New Radiator (Nissen), water pump, fan clutch, upper and lower hoses and the inline tstat mod with I believe the 180ºf stat. On Friday I drove it home with no issues. On Saturday I drove it around my local area doing errands and glanced at the Scan Gauge II and it was reading 215ºf which honestly freaked me out. Ed at IE Rovers said I should be concerned at 211ºf and that's when the aux fan kicks on. I've noticed the Scan Gauge has a tendency to glitch. Glitch meaning it will get stuck on a temp and not move, when I shut the vehicle down and restart it will resume with the temp fluctuations which I believe are typical. Correct me if I'm wrong but the electrical signal from the factory temp sensor through the ECU to the Scan Gauge II has a time lag? I personally think a analog temp sensor from the tstat housing into the cabin is the way to go.
Any recommendations for a temp sensor that will fit into the Extinct's tstat mod housing? Obviously the cable has to be long enough and a means to mount the gauge.
Continuing with with the cooling issue. This Saturday I warmed up the rig and it idled at 140ºf for a while, I drove it on the flats and it rose to 209ºf before the tstat opened and the temp went down to 180ºf I took it up a sustained grade and it never went above 195ºf keep in mind the OSA temp was ~58ºf
ATM I going to try and get it up to 211ºf to verify that the electric fan kicks on? Have any of you wired that fan up to a manual switch to turn it on earlier?
I understand that the d2 runs hotter than a d1. I believe I read where Extinct said Land Rover increased the combustion chamber heat to pass at the time higher emissions standards. But I also know that overheating these rigs can be a death blow. Perhaps, I'm fussing too much and this is normal for the Discovery 2?
Thoughts are welcome.

Just about any of the manual guages work, I personally use the Innovate Motorsports MTX-D https://www.innovatemotorsports.com/...-specification Oil pressure and temp in one gauge. You should also keep a small IR pen
in the cabin, any time you see it go that high check the hoses, thermostat housing and water neck coming from the manifold. Several members have had their temp sensor glitch on them, I also had one go bad and stick at a high #.
After you verify the readings are accurate if the thermostat is not opening till 209 let me know and I will send a replacement, no way should it get that high at highway speed ever. At long idle in the hot summer maybe, but not driving.

Thanks for the prompt reply. I have plenty of IR temp sensors I can use, that's a good idea and one I will utilize. I think I'll go with a analog temp sensor. I appreciate the recommendations.

Let's confirm its not a sensor issue first, go ahead and remove the thermostat element from the housing and see if everything is good. Also, go ahead and message me directly with you order # or email so I know where to send it, don't necessarily know forum avatar relative to emails or thermostat order.
