Glow Plugs Again

[NoDelie]

I know its warm out and it is not snowing, but i did change my glow plugs for the winter months to come. First thing is it did do the click once then crank, Second click set throttle. No problem on the old ones but how old where they, i did not know . The plugs where the green tops mitsu stamp . The paj came from Grande Prairie then Calgary. I am the third owner So how old where the green tops . Anyway took the old out put in the new easy as lemon pie bought from the store. But ha the joke on you , now no click and no second click . What has happened to the happy click can anyone get my click back . I hope the control panel is OK. I just got the plugs from the Greyhound express and like a kid in the candy store could not wait to put them in. The new plugs are Hyundai. Fresh from BC

Looks like the same problem. When I did my VW glow plugs only the bosh ones where worth putting in, the rest all sucked (lots of people had glow plugs for the VW only the bosh ones worked right).

Looks like the Hyundai do not work with the glow plug system.

which year is your pajero? you may not have the right glow plugs. you may need with 6.2 volts.

Pls read carefully this article.

Delica L300 (pre 1991) has 'Auto Glow Plug System' which uses 12V glow plugs with one relay.

Delica L300 (1991 - 1993) has 'Super Quick Glow Plug System' which was designed to shorten the glow plug warm up time. To shorten the duration, they used 6.2V glow plugs (on glow plug, it is written 6.2V [12V]) rather than 12V ones that they used earlier, with two relays (one for before-start and the other for after-start to prevent the burnout of glow plugs) and a dropping resistor. The main disadvantage of this system is that glow plugs were much easier to burn out because of the voltage. Hence, glow plugs needed to be replaced earlier than anticipated. Imagine the second relay is dead. That means your glow plugs will fail soon from overheating.

Delica L300 (post 1993) has 'Self Regulating Glow Plug System' which uses 11V glow plugs with one relay. If you understand what is written above, you will understand why Mitsubishi abandoned 6.2V glow plug system with two relays.

Delica L400 is the same as Delica L300 (post 1993) - 11V.

The key to understand the logic behind this is 'CURRENT' not the voltage. The range of current going through glow plugs on Delica L300 (1991 - 1993) is (80A to 40A). If you measure the current going through Hyundai glow plugs on the same model year, the range is (60A to 40A). This means, the glow plug warm up time for Hyundai 11V glow plugs is little slower than 6.2V ones. However, the most important thing is that there is no overheating problem. Hyundai ones have 'built-in resistor' (variable resistance versus temperature) to prevent overheating.

It is not caused by the glow plug itself, usually caused by the faulty glow plug control system.
If you don't know exactly, pls visit our shop as we will show you how it works.
Only Assiniboine can replace the faulty glow plug control system now as we know exactly what it is.

Also Hyundai and Mitsubishi has same OEM manufacturers in most part ( thus, same part numbers ) in 2.5 diesel engine.

The early 6.2 volt glow plug system is very sensitive to resistance from the glow plugs.The only glow plugs that i have found that work correctly is the Genuine Mitsubishi 6.2 volt glow plugs as stated in the thread linked by thedjjack.
I would put the Genuine glow plugs in and also replace the temp sensor.
Thanks

Give us an concrete idea how sensitive 6.2V glow plug system is.
Any analytical data?

Nice to see such a response. The info is great but i must agree i need the 6.2v green tops. Any other will just not do . The control system did work fine with the old green tops and started fine. The old plugs were fine just how old were they. So the prof is in the pudding no other will do in a double relay system . So back to the old ones Until i save the money for the next adventure in glow plugs.

Hey any one need any glow plugs.

[NoDelie]

Put the old ones back in all is well . Click is back . No more cold starts. This morning start was rough crank crank crank cough . crank crank cough. crank cough running rough then warm up click click click click control click off warm now you can get your Tim's now . The black and white smoke was as thick as London fog cough gage dam side pipe . Old glow plugs back in click start click set throttle .Wait ok go get Tim's now. All should be good . Rolling on

This thread and the other thread posted in the L300 section who have installed aftermarket glow plugs in to the early 6.2 volt system vehicles and then had non operating glow plug systems.
I have also sold aftermarket glow plugs for this system and then had to replace them with the Genuine Mitsubishi ones because of non operating glow plug systems when aftermarkets were installed.
I then tested the aftermarket glow plugs in my own vehicle (1991 2.5 Pajero) and found the glow plug system to not operate correctly.
I have collected this information through personal experience and being involved with Mitsubishi diesel vehicles for many years.
Thanks

I am not asking your personal experience or someone-said-like-that things.
As a part dealer, we need an accurate backdata or ability to prove that.
We tested our Hyundai genuine 11V glow plugs in all year delica/pajero/spacegear before commencing sale.
It completely fits any delica engine.
Why did mitsubishi abondon 6.2v glow plug?
Plz read throughly our posting.
If any doubt, bring your 6.2V delica/pajero with you. We can show you how it works.

Mitsubishi plug: works
Non-Mitsu plug: does not work

The data is fairly conclusive on this one, mate.

I have read somewhere that 2,5 and 2,8 engines use different glow plugs, also that "cold region" edition models equipped with "more powerful" glow plugs...Is it true?

Have noticed, when engine is well warmed up there are no glow plugs clicks at all and engine starts right away, even easier than gas cars. Are mine glow plugs so "smart" to know there is no needs to click for hot engine?


Thanks,

[NoDelie]

Up date on this topic. Was on holidays and picked up 4 plugs green tops at that, mitsu oem. And a temp sensor from Rocky mountain imports , located in Victoria BC. Great to hear the click again and starts easy. Just missed the HST ha ha. I think the temp sensor takes the smarts out of the plugs , click cold no click hot. Not sure but great to have my 89 rolling again.

[Pajerist]

Thanks for update.

Great to hear another Pajero is back to life!

Good luck,

The other thing I noticed with re-reading this thread was how skdelica kept going on and on about how "plugs in a Delica" this and "in an L300" or "the L400" that - I'm guessing they didn't read the fine print about how you're drivin' a Pajero.

Yes, I know, same motor, etc, but one thing I've learned with my glow circuit issue is that as similar as the motor is from the L300 to the Strada to the Pajero to the L200, the blasted glow circuit is not! Very similar, but usually just that little bit different that one can't just swappy-change things directly from one vehicle to the next.
