Peugot 406 Coupe V6 - Changing the plugs - TimR
Hi folks,

Has anyone tried changing the plugs on the Peugeot V6 406 coupe themselves? It is a fortune to take it to the dealer to have the work done and I would really like to have a go myself - but being a V6 and with not a lot of space it looks to be quite a complicated job. Can anyone give me some pointers? Also I know most plugs are pre-gaped these days but what should the correct gap be for this car?

Many thanks,

TimR

Hi

Make sure you use the propper Peugeot spark plugs in this engine, unless you want problems later on.
See the parts man at your friendly ( HA! HA!) local Peugeot dealer.
Using non Peugeot plugs can mess up the engines running & make you speedo have a fit too!
And im not pulling your leg!

yeah, I read your post about that - very odd!

I'm more concerned with making sure I can get to the plugs at the back of the engine - seems like you have to dismantle half the engine to get at them!

Unless you have all the tools and are really confident let someone else do it.If you go ahead allow plenty of time their is a lot to remove and difficult to get at the rear bank.Citroen ,alfa ,volvo use the same engine and they are all pigs to work on.

I'm happy playing with engines and unless there is a specialist tool required I should have all the necessary tools. I just wish there was a workshop manual available the V6 engine (or is there?) I presume I need a new gasket though?

No its not, the engine you are thinking of is the old 90 degree PRV V6. Volvo now uses its own straight 6 engines. Alfa uses its own engines also. This engine is shared with Citroen. Renault use(d) a similar version of it.
