Delica Canada | Mitsubishi Van Club

Hi again guys. Was planning on replacing my glow plugs this weekend (among other Delica related maintenance/repair) and ordered the NGK plugs listed on this site - however I remembered that my glow plug system uses a manual switch which introduces 12V to the plugs.

So - my questions is, can anyone recommend 12V glow plugs by part number for the Delica? Is there such a thing?

I also noticed that I have 2 green tops and 2 blue top plugs currently installed - interesting. She still starts up ok when plugged in, but stutters pretty good if not plugged in and it's below +5 Celcius. I would like the peace-of-mind in replacing all 4 at once.

Thanks guys
Steve

what makes you think that the ones for the deli are something other than 12v? I would think that they are 12v as they run off the same 12v as everything else in the van, maybe I'm assuming too much?

Hey Loki - By reading all the other posts it looks like the ECU steps down the voltage from 12V to 6V for the plugs when they're engaged during startup.
My manual switch sends battery power directly to the plugs, so I don't want to burn them out with 12V direct if they're manufactured/rated for only 6V....?

The glow plugs get 12V for the first "click" and then 6V for the second "click(s)". They are 6V plugs that get over-voltaged for the first cycle, so I believe they heat up faster.

That is my understanding....not very helpful for the 12V part number you were looking for though.

Correct.

The green top (original Mitsubishi one's) get hit with 8V which is why they are hotter = better startup/cold (and cost more) than the NGK's.

Better quality, however the NGK's are darn good enough.

hi the correct one is 6.2 volts with the green tip on the top.
pls dont mix up with the 12 volts. it has all 6.2 volts on delica prior to the newly design delica engine like june 1993 -1994 water cooled engine. its a different one. stay on what on it before not 12 volt. as you can see in the tip.
hope this help,
cheers;

Correct 6.2 V's Don't remember why I thought they we're 8's.

Original Mitsubishi glow plugs for the 4D56's (Pajero/Delica) :

This is what they look like.

And the part numbers for the Mitsu green tops are MD092392, available through any Mitsu dealer. Price is atout $140 for a set of 4.

I know that this will be resurrecting a dead post but..... Got back to the vehicle last night way back in the bush at about -20odd... small weak 1st click from near the glow plug control unit but no second click, no "strong" click like there usually is. No glow plug action. Ended up going direct from the battery as an emergency to get her going and it fired first try. I know the temp sensor recently got replaced along with all of the plugs. I have a guess that it is either one of the relays or the ecu that has decided to crap out. I don't really have the electrical knowledge to test each of these and being out in Canmore Alberta it's a bit tricky taking it into CVI or the like.

I have done a lot of reading on the site here and elsewhere and think that the best/simplest/most cost effective method is to wire up a manual switch with a starting relay from napa and just disconnect the current glow plug starting/monitoring system.

I know that the plugs are 6.2V and do take an initial overload. But you have to be careful and not over use the system or hold too long. Reading on some ford diesel sites, people seem to deal with 6V plugs by adding a resistor to the circuit to drop the voltage to the plugs increasing their lifespan.

While I understand the the "best" or "recommended" method is to go diagnose the whole system and remain with the automatic starting and OEM 6.2V plugs; would their be anything wrong with changing to a manual 12V system. I've searched the forum and haven't found an answer to this question. I understand that some of the cargo delica's went with a 12v plug system. Could you run a wilson switch, instal the 12V plugs and not have to worry about not having adding a voltage drop to the system? Does anyone have the part number for 12V plugs if they do indeed exist?

The desire for the manual system goes beyond the current problems as, for what I use the van for, there are times when it has to start and the extra control is beneficial.

Thanks everyone!!

When I use manual switch, I use this kind of plugs:



Those time to get warm is 7sec.

Don`t know if you can get those there, but mayby similar ones...?

We carry the HKT one shown the photo for Delica with 6.2 Volts. Call me if you need a set. They are Made in Japan OEM quality price $25 each.

Do you know what is warm up time those 6,2V plugs? And what is part number?

I dont know the exact warm up time, we have 2 different brand now for 6.2 volt glowplugs.

Another thing to remember when using a manual switch is that if you are wiring directly from the battery (as some have done) you are better off with 12V, no matter what year your vehicle is. If you are wiring through the relay / drop down resistor (the safe way to wire the system) then you want to stick with the 6.2V and you will have to hold the manual switch for about 15 seconds per cycle to get them warm enough. You can also wire through the 12V relay which I've been told you can do with either 6 or 12V plugs but you will be more likely to burn out the 6V ones just as would be the case wiring directly from the battery but with an added 'click' to tell you they're getting power... If you are putting more voltage into a lower voltage plug you will want to be very careful not to hold the switch on for too long.

Please correct me if this information is not completely accurate as in this matter a mistake can be costly!

If you have a manual switch due to faulty 6.2 V control system, 11V glow plugs are way better than 6.2V GPs.
There’s no way to know the optimum engine temperature for perfect starting in primitive manual switch.
That means GPs are getting too hot for extended time , that leads burning too quickly and buying new ones frequently.
You may need GPs every year or even faster due to hard starting.

We have too many threads for restoration broken ECU ( 6.2V super quick glow plug system ) in this forum.
Try to restore that one and go to Mitsubishi OEM GPs, or you may think conversion “11V self regulating glow plug system”.
Fortunately we have a Mitsubishi OEM GPs group buy opportunity ( $70-80 for 4 ) here and still on going.

I'll post them in the first thread and the people on the list can vote on which price point/shipping is the most cost effective/convenient. Once that's sorted, I'll get the funds from everyone, wire it over and then wait patiently until they arrive. I will be shipping them across Canada as well to those that cannot pick them up.

Here are recent debate for related topic.
