no holes as standard , you would need to get a hose adaptor then cut the hose you wanted to fit too
something like this eBay item number: eBay Item No. 131174368994 but in the size you want |

Interesting read, even more if you understand South African as I do
 , but the core message is there for all.
Seems the Puma even under normal circumstances and not high engine loads operates at already pretty high water temperatures, so risk of it reaching +100°C temps seems pretty high. http://www.4x4community.co.za/forum/showthread.php?t=122395 You never actually own a Defender.

I regularly see 101C on my coolant temperature, esp when doing 120kmh on a very hot day.
Usually it sits at around 91-93C. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Ehmmmm
 sorry Ericvv ......
am I late? 
By the way, all modern engine works closer to 100°C (or little higher than). It is needed for increase the combustion efficiency. Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Thanks Daniele, had seen that explanation already, yes. But it still does not make me happier, because it means that the gauge needle nicely stays fixed in the middle section until coolant water reaches 115°C, and that seems a bit too high to me.
So still would like to install a VDO gauge which will show the real water temp, and would allow to reduce engine load if I would see the water temp go higher than 100 or 105°C,................ without waiting until the needle flashes to red when the temp reaches a point above 115°C and maybe something pops at the same time. 
Right now with the factory set-up the water temp gauge gives us the same visibility on temp as swimming in a mud bath. Eric You never actually own a Defender.

Hi Ericvv
All modern cars uses the same water gauge strategy, Audi, BMW, Opel, etc. Also remember that the oil temp is already (very) important. For example, during the winter when the water reach the "right" temp, the oil may still be cold, causing cavitation on the bearing if you drive at high revs..... Right "way of driving" is: 1. engine warm-up : up to oil temp reach 70 °C 2. engine normal operations : water T °C from 85 to 110, oil T °C from 90 to 130 (race engines oil reach 150-160 °C normally) I like the gauges used by MD5 (Mario) forum member:

I would do something like that, but I do prefer the traditional analog black VDO gauges look. But in the SVX Mario's solution is not possible as the Garmin mount already occupies that place on the dash.
I will see if I can find a specialist here (think I know one) who can install a VDO water temp gauge, and who knows, maybe even a VDO oil temp gauge in the side panel of the black plastic panel left of the center console. I think it can fit nicely there and with my smaller than standard steering wheel, there is enough place left to give good visibility on the gauges. Eric This VDO series (Viewline) seems the best to match the Puma instruments (white needles) 52mm water temp gauge with alarm
Sensor for above giving alarm signal at 105°C
52mm oil temp gauge (maybe, vertically under the water temp gauge) You never actually own a Defender. You merely look after it for the next generation.

Now it would be nice to get the tdci gauge redone to use a td5 gauge

I was once told that the reason that temperature gauge readings were "manipulated" as described was to mask the effect on water temperature of DPF regeneration cycles and the excessive amounts of heat they generate.
The manufacturers don`t want eagle eyed customers reporting "overheating" when they see the gauge rise. Their attitude must be "Ignorance is Bliss" Don`t drive faster than your angel can fly! |

As a sufferer of too maany limp modes I tend to be agree with Eric.
Will be nice to have in the current gauge something between "normal" and "too hot". In fact any time that I suffered a limp mode by temperature, the needle just going direcly to the top without any advice no giving any time to reduce the speed or change th gear to avoid it. I already solve the problem usind a OBDC reader that gives an audible alarm if the temperature going over 105°C, but the position of the screen is outside the view of the driver, so you cannot see really the temp. The current gauge is already in sight. So why not use it? Cheers Eduardo MY 2007 110 SW PUMA 2.4: Big Fog of 64' MY 1994 Jayco 1207 Folding camper: "El Tremendo" Click image to enlarge |
