406 v6 cam belt

I don't know what the manufacuter says but my local peugeot specialist says that if it has done 60000 standard running it should be changed, if it has done stop/start running it should be changed at 40000. Or if it is 5 years old. I had mine changed at 45000 I also had to have the three guide pullies change as they had a lot of play in them. It might be worth having these checked at the same time. They were £150 for the set of three. The timing belt change was the same price.

If you get it done as part of a main service then you can save some of the labour costs as they have to take off the inlet manifold to change the rear spark plugs. (remember to get them to change the inlet manifold gasket at the same time). It's not related but there is so little room that it helps.

As the mechanic said, "It's an expensive engine to neglect". So I guess yours is over due.

Cambelt replacement seems to be a scheduled service with Pugs. But poking through Haynes, this group and other sources throws up conflicting information on when it should be done (and whether the tensioner should be replaced as well).

Haynes say nothing about the V6 but say 72k miles (115km) for other engines. In this group 160k km has been quoted as the recommended interval with, as i say, some controversy about the tensioner.

Does anyone know what the recommended intervals are for the various engines?

Hi,

Tensionners should be changed at the same time. I've seen and heard of many cases of tensionners which were worn a few hundred miles after the new belt was fit (which means another belt replacement, if not head / valves).

In theory should be written in the servicing handbook's provided with the car... BUT information may change with years & belts technology : for example first XUs were given for 80,000km then a belt tech upgrade (to HSN, which is 3rd generation, IIRC) makes it jump to 120,000km (or 5 years, this hasn't changed). Better thing is ringing at Pug's to know - they sould have the most recent specs.

HTH, G.T

I've had mine done at 80k miles

Had mine V6 done at 120000km.

My 2001 210bhp V6 engined 406 Coupe, lists the exact service items and intervals in the Owners Manual.

Service interval is 2 years / 20,000 miles, spark plugs are every second service (ie, 4 years, 40,000 miles) and the cambelt is specified every fourth service (ie, 8 years, 80,000 miles).

Note that this will NOT be the same for the earlier cars with the one-year service intervals.
