How do you change the spark plugs ona V6 Shogun, 1999

[paulcooper]

Any bright spark (pardon the pun) out there knows how to change the spark plugs on a 3000 V6 24V Shogun 1999 pretty please.

My spannerman changed my plugs (97 3.0 V6) in December, it's a hell of a job requiring the removal of all the injection/induction system in the V for acess. Plugs are also @ 100 quid a set.

At a guess as it will be similar to my Legnum

Remove teatray/engine cover

Remove any pipes under that/over the manifold

Remove inlet manifold, throttle cable etc

Should just be able to see the plug leads, you will then need a long and decent small spark plug socket, it needs to be the smaller 10mm one I think and it MUST be slimline as a chunky one will not get down the hole, also make sure it is a decent one, and doesn't drop the plugs, when lifting them out, otherwise you need seriously long needle nose pliers and some patience to remove the plug out the hole.

As its a Mitsi V6 its worth check the sparkplug oil seals, ie if the plugs are covered in oil on the ceramic part, you have a crap job coming up and expensive.

Anyways remove all three plugs, check to see they are the correct plugs, on the rear three make sure you put the longer lasting platinum plugs in, as they cant withstand the temperature and you know you wont be changing them in a few thousand miles.


Check the leads over make sure they all look good, I put the phone down laughing when I rang up Mitsi for a set of spark plug leads, only three of them, £198 rings a bell.

then of course putting it back together, reverse of removal, in theory, be careful you dont destroy any gaskets and get the leads on the wrong way around.

Front is the same just remove the coil packs, take them out, dont break them either, they are also expensive, but be careful with these that you dont drop the two bolts that hold them in, down the tube for the spark plugs.

Sounds daunting, but its not really that hard, and buy the plugs online, can get them cheaper £100, just make sure the three at the back are those platinum iridium thingamajigs

Dave Angel - how much did your spanner man charge you re labour?. Thanks everyone for your replies. Before I try it myself I am just trying to find out how much it would cost me. My Shogun runs on LPG and I have seen Mitsubishi LPG spark plugs on eBay for 33 plus 2.50 pa and p. I have also been quoted 70 quid to fit them so at the moment 105 for the whole job, supplied and fitted sounds quite good - don't you think.

How long is a piece of string? Spark plugs on my car is quote as a 1.5 hour job I believe, plus parts around £100-£150 could be anywhere with in that region maybe more

I think the labour time was around 2 hours although it was done as part of a major service, new belts/tensioners kit etc. I always tell my mechanic mate to use genuine Mits parts even though they are a tad pricey, my Shogun spends a lot of time around Europe so the peace of mind is worth it to me.

I wonder if you'll tell him that if you need a new radiator!

Mitsi wanted £515 plus VAT from memory for my 3.0 V6. The motor shop at the end of my road got me an aftermarket one for £208 including VAT.

Bloody hell, it'd be the shop at the end of the road for me too at that price!!

Apart from normal service items needing replacing, I've had 2 new rear calipers and 1 rear suspension arm in 4 years and 55k miles so not so bad.
