180, not 160. Do not buy the "fail safe" models, they will stick open. Align any jiggle device or weep hole at 12:00 position. Fan clutch should not spin more than part of a turn when warm after you release it. Freewheeling means it has lost the fluid inside.

 

Last week also had Fan Clutch "Viscus" replaced. No new core, just rodded and flushed. They said my heater core was pretty clogged and got a bit of that unclogged as well.

 

Sounds like once you do the the thermostat you will be ready for the chili dogs at the Varisty and a frosty orange. Plus two dogs walkin' and a bag o' rags. (two to go and some onion rings).

Note to others - The Varisty is the largest hamburger joint in the world, and has fed generations of North Ave Trade School engineering students and Atlanta fans of all sports. Big drive thru operation or seats hundreds inside.

 

I prefer the Chili slaw Dawgs myself. I, unfortunately live right next to the one in Alpharetta. My weakness

 

And a peach pie....

 

There is nothing wrong with running around 200*F.
I run a 195*F t-stat and I run high 190's to ~200.
Make sure your fan belt is routed correctly, it can be routed wrong but look correct.
If it is routed wrong your water pump and fan will turn to slow and can even turn backwards.
Tech section at the top of the page.

 

I don't know why but it scares me to see it occasionally go to 212 degrees under load on highway. When I back off accelerator, it comes back down. Will check belt but it has been at a well known land rover shop last week to put on the fan clutch. I figured they would of said something?? I'll look it up in the tech help anyway.

 

It is so easy to put the belt on wrong Rover techs have done it, it will look right, but it will be wrong.
Takes you 2min to check.
They wont be looking at the belt anyway.
Dont let the fear mongering that goes on about engine temps scare you, my truck spikes around 215* every day on the highway just as the t-stat is opening up.
Engines dont like to be ran cold, you need to keep them in their "sweet spot", 190-210 is the typical sweet spot for a engine to run.
You could replace everything cooling system related part and YOUR truck could still run at 212 under heavy load.

 

Funny, I have...... Water Pump, Radiator rodded out and flushed, new hoses, resevoir tank new....... Just scared about the Thermostat. Going down into the garage and gonna take a look at the belt and see real quick. I took a photo of the routing on my phone. Fingers crossed

 

See, you are falling into the "A" typical "call me and I'll tell you to replace everything on your truck" mentality that has been sold over and over on this forum.
If it ain't broke...
Some times to much information is a bad thing, like a electronic temp gauge.
