The One Item Every Land Rover Discovery Owner Needs And WHY! | 4K 

After years of owning a Disco, here is what I know.. 1. 160 degree Buick thermo and a s-10 thermo fan clutch help(engages sooner) 2.CLean between the rad and the A/C condenser (always fills with bugs/leaves/mud) 3. Most factory temp gages don't show real time info and by the time they show "hot" its too late for system to cool itself when under a load(Ford trucks do this also) 4. Aftermarket Alum larger core rad solves most issues.

Ultra gauge is the first and most important thing to install on a D2. It’s a must have!! Life saver on my D2’s. No Bluetooth. Direct connect is the way and no brainer.

Thanks for the shout out! Appreciate it.

An alternative to the ultra gage is the BAFX OBDll reader and the torque app, it will allow you to monitor all the engine parameters in real time at a substantially lower cost. Use your current android phone or an old one for a more permanent display. You can set high and low warnings for any parameter your ECU can output. The display looks way better than the ultra gage as well. 👍

Yes. That is a fact. 1st thing I did while signing paperwork during my Disco purchase - ordered an UltraGauge 👍🏼

Great advice and enjoy the channel. For those interested there is a cheaper alternative that works in the same way that I run on my Disco 1. Purchased a Veepeak OBD scan tool and the free car scanner tool for iOS. Can do the same thing and much more with a cellphone for under $20.

I never knew these existed! That’s a must have for an older rig and can save you a ton of money in the long run. I can see one of these in the Jeeps future 👀

Word. Thanks man. Imma get one today.

Most land rover discovery 1 people fail to clarify the huge difference between early D1's and late D1's. Specifically the Early NAS D1 vs. Late NAS D1 *2HO **DOES** mention 1996 and later OBDII in this vid, about 2/3 the way through (~6m stamp or so). I know this is about cooling and though may this may help some DIY'ers on the fuel side as well: Early (1994 - 1995, in the US & Canada [aka: NAS]: 14CUX - 14CUX ECU (engine computer module): Bank fired fuel injection; meaning that all four injectors on one bank would fire and then the other bank would follow (e.g.: 1/3/5/7 then 2/4/6/8). This contributes to poor idle, shorter-lived O2 (lamba) sensors, quicker catalytic burnout (shorter life), etc. - NO OBD2 [aka: OBD-II) .. it is an OBD1 [aka:OBD-I]... which is a huge difference (especially for this video) - NO evaporative recovery fuel pump assembly! The pump is different. - Most of the fuel system related sensors are different (or are specified differently) Late (1996-1999, in the US & Canada [aka: NAS]. GEMS *Note: the D1 was produced through EARLY 1999 and the D2 was ALSO produced in 1999 (call it late '99): - GEMS ECU (engine computer module); This is a true sequential fuel injection system (each injector fires independently of the other 7.. though at higher RPM I am pretty sure these gang fire in similar manner as the 14CUX (Bank Fire: 4 odd then 4 even... gang fire: all 8 fire together). - OBD2 [aka: OBD-II) ..an actually useful sensor port that is highly relevant to this video :-) - Evaporative recovery fuel pump assembly! The pump housing is different than the early NAS D1 - Most of the fuel system related sensors are different (or are specified differently) ...and many more :-) I add this, not (at all) to besmirch 2nd Hand Overland! I add it because my own searches for 1995 NAS (early) D1 wisdom so often falls into the Late D1 hole :-)) Hopefully this helps someone else too. :-) There is a great little document that provides the specs for the fuel system that can be found here (it says p38 but it covers all 1987 through 1999+ D2): p38arover.com/rover/p38a/Engine_Management/LR_Fuel_InjectionSystems.pdf

2003 D2 and a few things I did are Inline thermostat mod New expansion tank Ultragauge 180 degree thermostat hayden heavy duty fan clutch, and fan blade for that. Temps do not exceed 210 on the hottest of days and im in Miami Florida. eternal summer and traffic jams

I've got mine and still need to install it! I also have a inline thermostat kit I am planning on installing after my first winter with my D2! Thank you for this video!

Agree. 04 Disco. Best purchase besides re-doing the t-stat to make it inline

Jerry Arizona sent me over. Good review, I like the channel. Subbed.👍🏻

There is an australian produluct called a tm2. I use it on all my landies. It works of block temp eg bolt that threads into block/cylinder head. Best product!

Only thing that concerns me is that if you have an issue with anything plugged into the obd, you could possibly take out your ecm. Maybe not likely but possible. Same with those big brother insurance snoopers.

just received mine! very helpful information. Earned my subscription! Also i plugged it in for the first time without turning the ignition and it turned on right away. is this a sign that it will not turn off after using it for the first time on a drive? worried about it draining my battery.

I used to run an Ultragauge in my 3rd gen 4Runner. Great little gauge and I chose it over the Scan gauge was price and size of gauges. You can also use the UG Temp which shows the temperature of the gauge itself - so that would be an interior gauge.

Sold, thanks for the vid. We just picked up a Disco 2 and on the long ride home form getting it blew a head gasket. At what temperature should you start being concerned and let it cool?

Thank you for the advice have purchased a ultra gauge , what is the normal operating temp for a 1998 v8 D1 thank you

I run ultra gauge, 180 thermo, and a nissens rad. I'm cruising at 188 and idle at 198-210. When it hits 210 aux fan kicks in doesn't go any higher. Oh yea I add water wetter by royal purple as well.

Fed. First step before the 'ultraguage' is to use the correct grade engine oil for your climate in a D1 Rover 242 cu in. V8 ! This should be Castrol 20w40 mineral lubricant for the pre-cat versions and full synthetic 20w50 for other V8 models ? V

good info as always Matt! i actually just replaced my thermostat on my xterra recently! i might invest in a ultra gauge just for the extra features, specially the water temp feature. i got the door prize sticker and super cool of you to send a personalize thank you card! you rock brother! 😎🙌👍

So! My dad has a disco 1 with a blown engine and a totally eaten up low range transmission. Other than that its at a decent condition. Should I put it back together?? Love your videos a ton!

wow crazy good info!! Thanks

Sounds like an interesting addition. I wonder how it would work on a Tdi 200. Something to think about in the future.

Would you say there was Panic! .... at the Disco. all BS aside ill prolly get one on these for the WJ since heat likes to make things ventilate the heads fairly easy. informative and great content as usual.

Best piece of kit that I ever purchased for my disco. Once I had it I knew I was driving around too hot and got the 180ﾟ thermostat. It's not rare for me to see anything over 205 After the thermostat was installed.

The D2 temp gauge is similar. The needle climbs and the light goes on at 120C. Generally too late. The head gasket will be cooked. Much better if it started to rise at 110C. You can get a Nanocom for the D2. Does a whole lot more than measure the temp. Also you can set a coolant temperature alarm on a Nanocom. BTW, this happened with my son driving home. He filed up the reservoir with water and drove slowly i.e. 80kph, the 50km home. That was back in March. Car is still going well.

Ordered

Do you recommend the Ultra-Guage EM or MX?

Is there anything I can do on my 1995 land Rover discovery 1? I wasn't sure if I could get one of these as mines older.

Hello, I have a Discovery 1 300tdi auto with EDC, which Ultragauge is the best to order, the MX or the EM? Thanks, Bart

Im planning on doing an electric fan conversion for this very reason on my d1. Also the fan clutches on these ive found are temperamental. Especially at idle.

These plastic expansion tanks have been known to crack at the worse moments. And I have had a new one crack in less than 200 miles. I highly suggest replacing the plastic tank with an aluminium tank.

First!! I got my door prize stickers!! and i thank you for the Card as well, i appreciate the hand written card.

it does have an external thermometer, just push the EXT button on the climate control unit

Did the thermostat stop the overheating problem? I have the Ultraguage (Bluetooth) and love it- but all it does is worry me since my truck routinely gets to 212 even with the T-Pipe Thermostat conversion that eliminated the factory system (D2). I hate my truck running that hot- why can't we get these to stay at 180 degrees all day? I'm Wondering if electric fans and an upgraded radiator would do the trick.

I am really interested in a Disco series I, i am about to go inspect one in a few days so i am doing tons of research on the cooling system, head gasket issues, etc, would you say you were unlucky and had a premature thermostat failure??

Just curious, Matt… the 160 degree thermostat you mentioned. What other options are there and why did you go with this one?

Hermosa la disco... Al termostato de mi disco de 88 grados celcius, le perfore con una mecha un pequeño agujero para que tenga una pequeña entrada adicional de agua....(muy pequeña) Es TDI 2.5

Hi, what’s the temperature I should set up the ultragauge

I bought the 180F thermostat from the link when I did my head gaskets too, should I switch to the 160F thermostat in the link after seeing a spike of 215? How are you liking the 160F?

Acá en Argentina, fabrican para los defender y Discovery un radiador con una fila extra 😉😉

Hey! Will this work on a 1995 discovery?

luck you for having a normal tstat instead of that weird disco 2 one lol

So this Guage is telling you the motor is hot, but what are you doing to mitigate the actual over heating issues that our discos have?

How has the Rover been running with a 160 temp sensor in there? No issues getting up to temp I assume?

what do i do for a 95 to get this?

How about us folks with 95 OBD1 disco. What is our solution:)?

In the 300TDI D1 the water pump and factory water temp sensor are high up in the engine, so if you don't have enough coolant in the system the water pump starts to spin air! The reason the gauge give various readings is because the coolant isn't passing the sensor all of the time. The gauge will drop when when at the engine isn't working hard as the coolant isn't passing the sensor then soon as you accelerate (up a hill) the now super hot coolant will be caught by the pump and pass the sensor sending the gauge skywards. This normally happens after you drained and then refilled the cooling system after some maintenance work. I believe the V8 has the water pump in the same too high engine position. Of course the moral of the story is to keep checking your coolant level!

Does this work with TD5?

I swear by my Ultragauge.

Whoa... I literally came to your channel to ask you about my overheating issue, then I see this video lol (You can see our comments over at ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-68hbnFXrZpk.html) - Are you guys on Instagram?

Sitting in traffic Rover gets hot...within the first 2 minutes of this video I would suspect FAN clutch, restricted clogged radiator. The temp guage on dash is only an idiot light telling you its too late way after the overheat destroys the engine.. I use GLOW SHIFT GUAGES oil water and battery voltage.
