I've just fitted a combined SPA water temp and oil temp gauge to my Defender, and it has the option as well as displaying the respective temps to 1/10th of a degree, to set alarms for overheating.

So...what should these be set at respectively?

It's a Disco 200Tdi engine in a 110SW. Standard viscous fan but no shroud. As the gauges are so accurate I'm happy to keep an eye on them and I don't want alarms going off every time I tow something heavy up a big hill in mid summer, but a warning if something's going badly wrong and I'm about to cook the Tdi would be a good idea.

Thanks
 
At a guess I would set the water temp alarm to 100 degrees, should run around 85 - 90 in normal use, I believe at 1 bar pressure (most caps blow off pressure) water will boil at about 115 degrees. As for oil temp something around 120 mark, when towing with my Audi (big van in summer) Highest I've seen is 115 on the oil temp display while the water still remains at 90. Normal driving water and oil temps are pretty close match, no idea if the landy is similar as I don't have oil temp gauge fitted
 
200 std running temp will be mid 80s, work it hard and it will see low 90s, when cold outside and engine working light it drops to mid 70s and the heater is utter crap at them low temps.
If you need any form of extra cooling on the road you most likely have an issue, off road low speed working hard the temp can get up towards the 100 mark quite easily.
The above temps are the same on two 200 engined land rovers, both on capiliary gauges.
 
Thanks for the advice guys.

I finally got it wired up properly tonight...sender into an adaptor into another adaptor and into the thermostat housing! The good news is the "constantly buried in the red" old gauge, was, as I thought, knackered as it was nowhere near running hot. In fact, quite the opposite...a fairly good thrash on open roads had it going no hotter than 65.

It's a new thermostat, so unlikely to be stuck open, and the temp climbed fairly quickly to start with, but just stayed lower than I would have expected. Was the cool running due to the fact that I was taking full advantage of the Disco 2 transfer box ratios and doing 70mph (officer) and the cool night air flowing through the rad would keep things chilled anyway, and it would be a different story in summer with a bit of stop/start traffic?

What was interesting was how long the oil takes to warm up...you really need to wait much longer than you might think before it's up to temperature!
 
New stats can and do fail, especially cheapo land rover ones, apparently waxtstat is the make to get.

Hi Hard drive I have been looking at the Spa guages for quite some time...would you mind telling what adaptors you used for your 200 tdi oil and water and where you bought them?

Did you have any other issues setting it up?

Many thanks
 
Sure. I needed this...

"ERC8973 Temperature Sender Adaptor Fine Thread Land Rover late Series 2A and Series 3" because my thermostat housing was the fine thread (M16x1)

...and then a couple of others, which were all available from Steve Parkers, they were Durite adaptors, to get down to the 1/8 NPT thread of the sender units. So my water sender screws into a Durite adaptor which in turn screws into ERC8973 which in turn goes into the 'stat housing.

Oil temp was a lot easier...one adaptor into the top of the oil filter assembly...there's an obvious "plug" doing nothing on top of the housing.

In terms of "setting it up" I've not really done much in terms of alarms etc yet, it shows the numbers which works for now and at some point I'll tinker around in the menus. It was very easy indeed to wire in...positive, negative, senders and menu button.

I have to say they are pricey...I got mine second hand for £50...new they are £200 and that is a lot, however I guess it's piece of mind. Seems a bit daft in many ways having 1/10th degree motorsport spec gauges on a glorified tractor engine that you tune with a hammer and can run on chip fat ...but as I said it was cheap!
 
I'll take some pics if you want?

Bit worried about my temps...water is in the mid 60s which is low, and although my stat isn't a waxstat it's a reputable one. Interestingly the oil is at a very similar temp too. I could test the 'stat on the hob with a thermometer I guess? Or could it be that with a properly accurate gauge these engines it just shows that these run cooler than we think they do?
 
thanks, that would be great, pics are always good...it does seem that these engines are overcooled ....my guage seems to never get very high even with a fully covered grill...hence the reason to fit a super accurate guage to find out for sure where I am

The 200 is known for running cooler and that's why I like mine. Try running it hard off road, you'll probably notice the temp rises a bit more than 60 with no airflow and the engine being worked hard
