I have a newly imported PD6W, and want to have the cam belt replaced. The vehicle is very low mileage for its age, 1998 and only 40,000 miles, but without a service history it makes sense to play safe.

Can anyone who has done this job recently advise me about which parts are necessary, and where to get them?

Milners only supply a belt, 187 teeth.

Mitzi Bits list two belts, 187 teeth and 259 teeth. Is there a simple rule for which one?  
They show a "kit" which includes two pulleys, but is out of stock. The only parts they list are the Belt and a Drive Sprocket.

The obvious parts are Belt, Tensioner Pulley, Idler Pulley.
Is the Drive Sprocket always necessary?
I am hoping the Adjuster doesn't require replacing because it's an expensive item.
It makes sense to do the Water Pump while everything is disassembled, and that isn't expensive.

I don't have a local Mitsubishi dealer with experience of this model. The garage I intend to use are specialist engine guys, but haven't done this one before. They've asked me to provide the parts, and it would help to get in advance what I know will be necessary.

One more question:
I cannot find the 6G72 Engine in the TerraMonkey pages. Am I missing a trick?

Had mine done last year and bought parts from Mitzi Bitz. Gave them the registration and they supplied the right bits. I had plugs and leads done at the same time as they are apparently a sod to do so whilst it was in bits it made sense to do it.  Mitzi Bitz leads didn’t have a collar on them though so I took them back and bought them from main dealer (about £150).

I suspect different teeth numbers is to do with whether 12 valve or 24 valve. As they are both SOHC per bank, I wouldn't know which has more teeth!

Thanks for your contributions. I agree that it makes sense to do the Spark Plugs at the same time. I don't think my leads need replacing.

MitziBitz don't hold all the parts at the present time.

I can add to the post for the benefit of others in the future:

By a stroke of luck, Milners have just researched this job for another customer and found good information on an Australia website.....the petrol Delica is more common out there. The recommended kit is:
Belt
Adjuster
Idler Pulley
Tensioner Pulley
Camshaft Oilseal x2
Crankshaft front Oilseal
Water Pump.

The Crankshaft Drive Sprocket offered on the Mitzi Bitz website is an unknown at this stage (have to wait and see what my garage say after inspection).

Milners can obtain all the parts OEM (2 weeks order lead in) at considerably lower prices than quoted over the counter by Mitsubishi.
Water Pump is the one part I would opt for aftermarket as Mitsubishi is 3 times the price.

Hope this helps, and hope the job on my vehicle goes okay.

As matter of interest, Andyman - while thia topic is live:

The information I have seen says that the 6G72 Engine, described as SOHC, can be 24-valve or 12-valve (confusing, but there you are). My Chassis Number on the Mitsubishi database used by the local main dealer shows a drawing with twin camshafts on each bank of the V6. The DOHC 24-valve Engine was more powerful and used on the 3000GT (with or without turbo).

It would be really helpful to know where I might find more information on the 6G72 Engine. I don't think it is there in the Terramonkey Files. Does anyone have a reference for the relevant Workshop Manual having been tracked down and posted on the Forums?

[andyman]

My old Haynes Pajero manual (up to 1996) shows both SOHC and DOHC V6 engines. It should be easy to tell which you have by the shape of the cam covers, As usual with a DOHC engine, the Cam belt cover(s) reflect the shape of the two cam sprockets, being a lot wider than the round topped single cam sprocket/belt cover. Hope this helps.

It is still something of a puzzle, thanks Andy. I too have that Haynes Manual, Pajero 1983-1996, and I refer to it alongside Pocket Mechanic by Peter Russek. I'm still hoping that someone will post a link for the relevant Mitsubishi Workshop Manual.

The 6G72 block is set further back in the engine bay than with the 4M40, and mostly obscured. I don't think cam covers are exposed until disassembly for the cam belt job. All will become clearer in due course, I guess.

The point which I have been trying to clarify is this matter of 12 and 24 valve variants of the 3L engine, which are both listed as SOHC. This doesn't immediately make sense, because 24 valves presumably uses twin cams, as described (over the telephone with a main dealer parts department) from Mitusbishi drawings based on my Chassis Number. From what I have read the DOHC engine is a considerably more powerful unit, which isn't used in the Delica.  

Hey ho.

[andyman]

Yes, I read that the DOHC unit wasn't used in the Delica, but perhaps it was in the Pajero? Strange. I have seen double valve motors where rocker arms work the second set of valves, working off the same camshaft that operates the first set directly.

Not much help, but I had mine replaced at SVS in Verwood. He did all the belts and waterpump, and was able to source the parts before starting the job very quickly.

They must have the secret garage computer that tells them exactly what they need for the model.

I should have asked myself whether it was dohc or sohc, but had a lot going on.!

You could always remove the cam cover and see if there is one or two cams under it.

No time yet.

Well, I haven't got my vehicle outside at the moment, it's parked at a friend's place (awaiting dvla registration). But, when I've looked in the engine compartment....and I'm still familiarising myself with it.....the cam covers are not accessible until quite a few other things have been taken off or moved. Am I missing a trick, or going senile?

I've found a thread on the General Technical Forum from November 2018, Subject 3.0L V6, where Gypsy offered "a full service manual for this engine". The link doesn't exist or has expired/been removed. Is there any way to recover it? Green Grouch found it at the time....can he be asked to share it again?

Many thanks....I'm an oldie.

[JimmyG]

There you are, Green Grouch......I am going senile!

[Green Grouch]

I didn't get involved on the part search I'm afraid.

She was good as new when I got her, so wasn't going to even attempt to take the v6 apart in an afternoon off, being my work transport.

My garage sourced the parts, apparently quite easily, but as said they seem to have special access to something special.

Agreed on taking the cam cover off. It's not a five minute job on a v6, hence my comment.

I struggle to find time to give mine a bath at present!

Now, I'm just concentrating on getting to retirement with the health I need to enjoy doing these thing's properly,and actually have time to acknowledge the neighbours who hold you up with questions, about why I don't get a cheap small car that I can put in the garage, as they leisurely put their kia in the garage after collecting their newspapers for the day!

Sorry, I'm bitching. Had a stressy day on that front.!


The 4m40, was quite simple to fiddle with.

I was confident enough to play with that, with good instruction on here that is.

For all belts, Inc auxiliary, cam, water pump, idler bits, ( I can't remember how many of those), it was best part of £500. 😄

Thanks ArthurArthur.
The balancer pulley sounds expensive/hard to get hold of.
Were there symptoms of a problem with it?

[JimmyG]

I have posted previously on the parts break-down for this job.

It is good practice when renewing the cam/timing belt to replace also (parts with bearings under tension),

1.Belt Tensioner (the clever bit, and not cheap)
2.Idler Pulley
3.Tensioner Pulley (look very similar, but one of them revolves off centre)
4.Water Pump
5.Belt (of course) (some recommend being prepared to replace Camshaft Oilseal x2 and Crankshaft Oilseal Front, if required)

Milners obtained all these parts for me in June, genuine Mitsubishi, at prices approximately 40% less than OEM. The order period was four to six weeks.
I opted for an aftermarket Water Pump (less than half the price of Mitsubishi).

The job was listed in a trade workshop bible as four hours, my engine specialist allowed himself five hours. SVS know their stuff, worth paying for their expertise and experience, if you are fortunate enough to be in that neck of the woods.

So, in answer to the original question I paid around £250 for all the parts and £250 for labour....this includes vat and allows for the cheaper water pump.

I had the spark plugs replaced while things were a bit more accessible (another £75 plus and hour-or-so labour, would otherwise take two hrs).
