Hello All,
I am moving/continuing from https://www.pajeroclub.co.za/forum/view ... 573#p21573
started as a desperate overheating problem that I have with a car before paying it in full.

The reason I am shifting this thread from Engines and Engine Management to Electrical and Electronics is DON'T OPEN THE CYLINDERS HEADS, DON'T BUY NEW GASKETS, DON'T TAKE OUT THE THERMOSTAT, DON'T BUY A NEW WATER PUMP!!! Until you check the temperature gauge.

The simplest way to check is to swap the dashboard with one from another similar car or from your garage, second hand parts etc.

Please don't take me wrong... It may seem naive and obvious what I am saying.
But this is not a specialist advice.. Its a analytic Pajero owner experience who went over the internet desperately looking for a solution to a problem that proved to be far smaller than I thought.
Moreover I found out (and Dave can confirm) there are many people having the same problem out there. So many that smells like a factory defect for certain series of Pajero...

Now: The question I am throwing over is - Has anyone changed the temperature gauge from the dashboard? Is there any blue print? Can we get to a good practice together?

Thanks or that bit of advice, too often we depend on the instrumentation in our vehicles as being correct............wrong.

I have found them to be generally good looking bits included in the dash to enhance appearance rather than being functional and accurate instruments. I have always relied on after market units as I don't trust the factory ones a bit.

IMHO overheating is a tricky one and not to be taken lightly, it can cause some expensive damage, and the more common issues noticed are as follows in $my opinion:

Anothe members issue with overheating over the same time was a radiator cap and the other replaced the radiator on a gen2

Starting from cheapest

Radiator cap
Check for leaks and at all joins and T pieces - Gen2, not sure if same applies to Gen3
Clean, flush and rod radiator - never done often enough and a lot of concerns around gelling in the forums
Test Thermostat and replace if necessary
Test for gases in radiator water
Temp gauge check and test
Water pump
Temperature sensors in engine bay

Sure there will be others

I don't believe there is 1 perfect solution to this but the right questions and checks can save a lot of time, effort and money.

Hope this helps someone as well when having these issues, start small and work bigger methodically, making sure you eliminate the issue without doubt, then move to the next most likely issue

Cheers

Hello and Happy New Year!

Done over 5000 Km with my "new" Gen III 3.5 GDI Pajero.
Replaced the dash board and all problems gone as mentioned.
But the one I have is also used and on stand by because of Fuel indicator problem (hehehe...)...

Anyone can advise where can I buy a good dash board from?

Again thanks everyone for your kind assistance in the past year with my past issue...

Hi guys,

There is a simple way of testing the temp gauge in the car. The price of such a test will be the cost of a cheap electrical temp gauge that you can get at your local spares shop plus the time that it will take you to rig the gauge. If you want to do the test, here is the way:
a. Buy a cheap electrical temp gauge and some tape from the local spares shop.
b. Connect a long piece of flex to the outside of the temp bulb - remove a long piece of insullatation from the flex (this is to act as the earth wire so make sure that it makes good contact with the bulb).
c. Connect a long piece of flex to the positive terminal of the bulb.
d. Press the bulb tightly against the top hose and wound some tape around it till it is tight and in good contact with the hose. Use some extra tape to ensure that there is no outside air reaching the bulb to cool it down.
e. Connect the earth wire from the bulb to the car battery.
f. Connect the positive wire to the positive on the gauge - remember wire to be log enough so that you can get it inside the car.
g. Connect the earth of the gauge to the earth terminal of the battery.
h. Make sure that the wires in the engine bay are out of harms way!!!
g. Start the car, drive and compare the two temps - the gauge in the instrument panel and your extra gauge. The readings should give you an indication of the accuracy of the car's gauge.

Hi Guys, 3 weeks ago one early morning i started my 3.5GDI Exceed and started driving from Walvis Bay to swakop and just after approximately 1 km i noticed my temp guage climbed completed up to over boiling point and then started coming down and going up again etc, i turned back and opened the bonnet but all was normal there was no overheating, i then searched through Pajero sa and Pajero Australia and found quite a couple of the same problems , i removed the dash, cluster and removed the board instrument panel and had a Tv repair technician look for dry joints and he soldered 2 or 3 suspicious sections and then i replaced all and yes my problem has been solved but now i have a new problem since the dash was removed, my speedo is sticky it jumps as i accelerate and when i come to a stand still is stays on 20 kms/ph and after i have tapped the dash it goes down to zero, any assistance on this problem would be appreciated
regards

[4ePikanini]

do you have a gps to measure the accuracy of the speedo? Maybe he removed the needle to do his work and put it back in the wrong place?

Or there is dirt in the mechanism?

Or there is still a dodgy connection?

[calvinc]

Marius i removed the instrument board (pc Board) from the cluster as per the pics you downloaded for me, their is no mechanical parts in any way its all electronics, i did connect my gps and the speedo and gps speaks the same language maybe 1 km/ph difference, the needle jumps up as you accelerate and even when you slack down as well it jumps from say 60 to 50 to 40 and so on.

Your problem, after reading around many others similar, only makes me think Factory Defect (!) But these are 8-1o years old cars and I doubt Mitsubishi would bother...
I'm also sure the 3.5 GDI Dash Board is different then the DID and a bit more complex.
As u may read in one of my prev post I have solved my temp gauge problem but I got myself a jumpy fuel gauge on the "new" dash board.
Just wrote to Japanesesvehicles.com website guys and waiting to see if they can sell this dash board. Mine is 5 speed.
I think u should stop trying to fix it and just find another one and replace the naughty-faulty. Will be a time saver. But its just my opinion (owning a GDI for jus 1 months)...
Stan
BTW, what's ur fuel consumption? Mine goes 17-18 l/100Km in town and 15 l/100 Km on highway... Huge hey? (Correction Sorry!)

[calvinc]

Hi Stan
You mention you are getting 17 kms/pl , that is tremendous as my 3.5 GDI only gives me approximately 7 to 7.5 kms/pl, this is my 3rd 3.5 petrol pajero and have never got more. regards
