Display coolant temp Volvo D2-50F

[CaptainRivet]

Hi all,
Is there a reasonable priced solution to display coolant temp on a Volvo D2-50F.
The MDI data seems to include that and a coolant sensor is build in too but I cannot display it anywhere.
Option 1: Volvo easy connect interface cost 510 Euro, 2 engines so 1020 for coolant temp…no
Option 2: yacht devices nmea to edc interface, works but is 190, 2 engines 380Euro…well still too expensive for just coolant temp.

Does anybody know what oil temp sensor fits and what display works with it.
Thank you

I have just done this job on a Volvo D1-30
I purchased a temperature gauge (Kus) and sensor replacement with overheat alarm.
However I did find that connecting the Kus gauge to the original sensor gave me the correct reading for temperature.

Thank you
On the D1 its easy as coolant temp is not part of the MDI bus but onthe D2-50F it is.
So which sensor can l use to get temp displayed and MDI doesn't complain?

The MDI unit just monitors the temperature and if it goes out of range for more than 10-20 secs it will sound the alarm and put a graphic on the lcd display on the tacho. There is nothing in the programming of the MDI to allow temperature display.

There are all sorts of electronic gadgets out there for putting all your engine data and water tanks etc. on the chart plotter but they are not cheap, and some require an awful lot of setting up and jigging.

I was just pointing out a cheap and reliable method for getting the information you want.

Or are there some blank threaded opening which i can use with a standard water and oil temp (or better oil temp+pressure sensor)?
What thread size do they have and where do i find them on the engine?

Thank you, yes i know and don't need them as the mdi doesn't put out anything useful...
On d2 the the watertemp is shown in mdi, on d1 not.
So you unpluged the sensor from the MDI and connected it directly to the Kus?

What I know D1-30 has just a threaded and blanked off opening next to the original sensor so you can just screw in a standard 20Euro sensor next to original and connect that to your Kus or whatever you wanna use. Thats what i am looking for.
I don't have that, maybe some other location?
Should be there as you can get extra sensor for the MDI but where are they on the engine? That's where i can also put a standard sensor...

I don't understand this discussion. The D2 series uses an instrument bus from the MDI to the (EVC) tach with display, and can be daisy-chained from there with a 3-conductor pigtail on the tach. Add-on instruments have a male and a female 3-pin connector so can be added on to the previous instrument. One of those optional instruments is a coolant temperature display, from 40°F to 200°F. So why not just buy an EVC temperature display and add it to the tach? Am I missing something or do you just like doing things the hard way?

Greg is exactly right. We’re installing new D2-50F’s next week, and purchased optional Volvo EVC temp gauges to be installed alongside the standard EVC tachometer. The temp gauge simply daisy-chains off of the tach using a short (included) cable. I have the hardware sitting in my salon at the moment, and can send you the part number when I get back to the boat tomorrow.

Didn't know they exist... Well its Volvo so lets see how much they cost. Assume not under 150Euro...
The part numbers would be welcomed
Are there EVC sensors for oil temp and pressure available from volvo for the d2-50F too? I know only a warn sensor for oil pressure is fitted.
If yes then the yacht devices dongle volvo to nmea would make sense too.


From KUS a temp gauge is 25 Euro and the sensor is 14 Euro. Running a cable from engine to helm is easy on my cat and I install a 2nd autopilot and Lithum battery anyway, so need to root some cables there anyway. Just need to know if there is a blanked of threaded opening to install a 2nd sensor. And if yes what thread size does it have. Not really hard way but much cheaper way.

And i wanna have oil temp and pressure too, no sensor on the engine anyhow, so need to retrofit that too. On d1-30 i would know where they are located but not on d2-50f...

[CarinaPDX]

In addition to coolant temperature there is voltage, fuel gauge, and an error indicator (with 6 or 7 idiot lights IIRC, so don't have to read the small LCD display in the tach). There is no oil pressure gauge: IIRC there is an oil pressure switch on the engine so no raw data. (I suppose you could add a pressure sender with a tee off the pressure switch, and a generic pressure gauge.) The instruments are available in black and white so order the matching ones.

Edit: example of temp gauge: https://www.ebay.com/itm/264810688260 You still need to order the bezel separately.

Thanks, I would have chosen Beta instead of Volvo but I bought the cat with the new Volvo engines+saildrives+ exhaust+…basically both engine rooms are new

Thanks Greg for the link and prices…the usual Volvo pharmacy
Just look at those ridiculous prices for the temp gauge…162$ + another 163 for 1,5m cable if you wanna mount it somewhere else then next to the instrument panel which is in the foot room mounted on my cat. And that’s just for 1 engine
A Kus temp gauge cost 25Euro, the sensor 14 Euro=39Euro+Max. 20 Euro cable…just need the Location where I can mount the sensor

Plug&pray solution for 189$ For all available engine data at once:
https://www.yachtd.com/products/engine_gateway.html

Just daisy chain in and you have all available D2-engine data and on nmea and on your chartplotter with proper warnings. I additionally have their NMEA to wifi dongle already installed and so all NMEA data is on the boat WiFi readly available for e.g. all iPads
Have 3iPads, 2x Mini and 1 ipad2 fixed installed at the salon Nav station. Ipad2 is mirrored/remotely connected permanently with the Raymarine chartplotter on the helm/in parallel ISailor installed which can remotely control the autopilot too, the 1st mini shows all sailing relevant nmea data on gauges and the 2nd mini monitors my Electrodacus BMS of my LifePo4 house/in parallel the Victron BT Network to monitor all Victron stuff. You can get the iPad mini used for 50-100Euro on eBay or local platform. Is a perfect smart display on the always shaded nav station in the salon. All have ISailor and Navionics installed and connected to a 10Hz Garmin Glo2 BT gps puck as backup chartplotter and Nav device.
No drilling holes and installing another gauge on the already crowded helm station.

Perfect that’s what I needed.

Do you know if I can add oil temp and pressure like this too?
Should be M18*1.5 too for the sensor but are there mounting holes additional available to the Volvo Oli pressure switch?
