Looks like a very good place. Wish there was similar around here.I just took it to the local rad shop

Do you have thermal imaging camera?
Remember that three will always be a delta between the actual water temp inside, and the outside of the hose or housing, also due to the way IR guns work different surfaces will give different readings you can see different temperatures on reflective or dull surfaces.Hi guys.
Took the land rover out this week, and got it to just under 100 degrees again on the gauge. Stopped and popped the bonnet and pointed my cheap infa red gauge over the engine around the areas of the water ways. The max temp reading on the Infa red gun was showing 85 to 90 degrees.
So I cleaned up the main battery earth and tried it again. A slight improvement, it's now showing a max of 92 degrees tonight. However the infa red gun is showing 82 degrees. So both times the IR gun is showing 10 degrees lower!
I then got my jump leads, put one end on the negative battery terminal, one end to the block, no difference on gauge. Same result when touched on stat housing.
I then put the jump lead on the bulkhead earth post, which also made no difference.
I'm not 100% sure the chassis earth is good enough. But if I've done what I have with the jump leads. It shouldn't matter should it?

ah you need to sort the earth out first then.
i like to have a separate earth strap between the chassis and engine/gearbox. i don't like the clamps.
whip your dash off and stick a wire from your bat neg directly to the temp guage earth and see if that helps. if so go and redo the dash earth point on the bulkhead, body to chassis and all that.
If you have a voltmeter, it's worth checking the voltage supplied to your gauges - it should not vary with engine revs. If it goes up and down with the revs, the voltage regulator may be faulty.
yup, to the right of the brake servo it is, but the connectors/wire behind the dash to that earth point might be corroded/brokeCheers Trax. Isn't the gauge earth's that post on the bulkhead? Just wondering as I've already connected my jump leads to there and it made no difference.
The annoying thing is, the gauge doesn't read too far wrong on tick over.

where are you btw? anywhere close to me / north east?
Ahh I see. I'll investigate that then thank you.
I'm West midlands, Wolverhampton based unfortunately.
Do you think an M10 washer is enough contact for a good earth? Providing both contacts were spotless?
Just doing some reading... and apparently the alternator needs to earth through the engine? I didn't clean the mounting points up for the alternator when fitting?
yeah m10 will be fine.
get your multi and stick it on resistance, then start testing all your earth points/alt/engine etc to your bat neg
ah,I'm not sure how to do that trax. I'll have a look online. I'm only familiar with using the multimeter for voltage
ah,
it'll make things a lot easier
also look at volt drop; which will come in useful
didn't someone make a guide on here covering this?
here we go, have a read https://www.landyzone.co.uk/land-rover/cowasakis-electrical-tutorial-part-2.285354/
