Glow plugs.....glow plugs.....

[MardyDelica]

sometiem relay is the problem.
and some time the glow plug is the problem.
most common problem on this L300 and L400 is the glow plug ecu module on the older model.
i guess the 1997 has a new upgraded one

HKT CP-06 is the 6.2V so you are safe. Do not install 11V plugs in your 92 Delica or you may risk burning the tips off and causing piston/head damage.
.

Hey Jfarsang can you elaborate on this? how is it that a 11v plug is an more likely to burn and break then a 6.2??
Do you have an alternative to replacing/repairing all the factory stuff that will be as reliable as the method I have suggested?

Trailmaster and I had the same issue installing HK Cp-06 Plugs in both our machines,After swaping the ECU's testing relays ETC we determined through deduction it was the plugs them selves!!Put the old ones back in and Voila!!

I had bad luck with the HKT glow plugs as they only lasted for 6 months after I put them in. I was having a hard time starting checked the plugs and two were dead. Then checked the old ones that I had taken out the time before, and found that two were HKT and two were OEM ones and guess what the two OEM one were still good and the HKT ones were dead.

Not sure if its just my bad luck but I won't use HKT Glow plugs again!

Good Luck

Hi CJ

My mistake. 6V plugs in a post-1992* (1993 or newer) with the watercooled head-turbo using the 11V glow plug system is the bad combo.

This is what can happen if the incorrect glow plug is used leading to piston/head damage. In this case, it was an owner who used the correct glow plug as per the manual recommendation in the delica wiki, but because they have a 1992, they assumed that they use 6V glow plugs. Unfortunate for them, it was the wrong glow plug for the engine/production month.

*Some Nov/December production 1992 L300 models come with the 11V system/water cooled turbo.

that picture makes me cringe hahahaha

You wouldn't want to see the #1 piston. top looks like a black golf ball.

Sorry to dredge up an old thread...

I can confirm that on a 1991 Delica with the super-quick glow system (6.2V glow plugs, two relays and a dropping resistor under the driver's seat) HKT CP-06 glow plugs do not work.

The issue is with the glow computer. The computer monitors the resistance of the glow plugs to determine how hot they are, and so set how long they need to be powered for. Resistance changes with temperature and HKT glow plugs have a slightly higher resistance than genuine Mitsubishi ones, so the computer thinks they're already hot and doesn't do the initial glow.

(This is of course when the engine coolant is cold, if the engine coolant is hot the coolant temperature sensor takes precedence and disables the initial glow.)

If you get the engine started with the HKT plugs, you'll find the computer still does the after-start glow plug pulsing (that clicking that goes on until the engine is a bit warmed up). I presume that this is because the after-start relay is powering the glow plugs with their rated 6.2V through the dropping resistor, and monitoring their temperature isn't necessary because you can't overheat them.

I ended up biting the bullet and installing genuine Mitsubishi glow plugs, and the whole system works perfectly again.

Anyone want to buy a set of almost brand new HKT CP-06 plugs?
