V6 PROBELMS

[bennyboy200]

Hi,

I just brought a Pug 406 V6,

I think I have made a big mistake. its got 153k on the clock, i c\an hear a slight knocking noise when i pull away and stop sometimes. I think its an engine mount. Is this an expensive fix???

seems like the engine is running well which is a good thing :-)

Also the heater dosent work!!! big problem as its winter. any ideas what this could be? will a peugeot garage charge me a fortune to get it fixed?

I wish i didnt buy it, i can see it costing me a lot of money. any ideas on the above problems?

Thanks
Ben

Hi Ben, welcome. First up, what year is the car? What's up with the heater, totally dead, doesn't blow, doesn't get hot?

Slight knocking noise could be a mounting, I'd look at the one on the back of the engine first.

Welcome along!

Knocking might not be the engine mounts; it could easily also be the front anti-roll bar drop links. Easier and cheaper to replace than engine mounts. It happened to me, and I thought it was brackets for my exhaust having failed (and the exhaust then knocking against the bottom of the car - a proper metallic "clunk" noise when going over any bump or making any kind of sharp turn - most unsettling!). The parts are cheap and any independent mechanic or small family-owned garage would be able to do that for you without it costing the earth.

You can check if it is the engine mounts fairly easily though - open the bonnet and look at the engine while you get somebody to sit in the car and rev it. If the engine moves around a hell of a lot, then yeah - one (or more) of the engine mounts could well be your problem.

Not sure about the climate control / air con / heating systems on board the 406 as mine have just always worked (touch wood) - no idea how to sort those out. There will have been other people with similar issues. It's quite possibly very simple, like a burnt out heating element.

Don't worry too much about it - the 406 is a nice choice. This is almost certainly a car you'll find it worth spending money on - the 406 is a comfortable and stylish car, and the V6 is a nice lump to have under the bonnet. As long as you maintain it well (as you would with any other car), you'll have many more miles of happy motoring to look forward to.

Some pics would be cool; show us your car!

Thanks alot for the info. really appreciate it.

I will check these things out when i get home. The car is nice really smart looking and the engine sounds very good.
but i am worried it has been thrashed and no proof of service for 40,000 miles. i will try and upload a pic when i get a chance

the heat comes out but the fan is not blowing it. i think it maybe the fan.

Is this is hard job to fix?

Cheers Ben

what year is the car as i have a spare fan here
if its a early model

[bennyboy200]

Its a 98 S reg

Knocking might not be the engine mounts; it could easily also be the front anti-roll bar drop links. Easier and cheaper to replace than engine mounts.

£30 for a pair of drop links, £20 for a top engine mount
1.5 hours to replace drop links if you've got an angle grinder, 5+ hours if not. 20 minutes to replace the top engine mount


bennyboy200: change the top engine mount. If it's the original part it's WAY overdue replacement

[bennyboy200]

Thanks alot for your responses.

I will have a good look when i get home.

the heater moter is under the passenger side glovebox just give the wires a wiggle as sometimes they work loose,and if you want one i have a spare here.

[bennyboy200]

Just drove it at lunch and the heater was working!!!! maybe there is a loose connection.

I will let you know if i'll need the motor.

Lovelly car to drive.

Is 153k a lot for a 406? am i likely to get another 20k out of it?

Thanks alot

As long as the car is properly maintained, there's no reason you couldn't keep it going a lot longer than 20,000 extra.

Big important thing is to check the timing belt history - was this ever changed? If not, that's one thing you'll want to have done, and the water pump should be changed at the same time. It's a bit of maintenance you'll want to do every 8 years or 80,000 miles - gives you peace of mind.

[bennyboy200]

do you have a ruff idea of the cost to get the belt changed??

Thanks
Ben

[highlander]

The kit is cheap enough, I gather; it's just a labor cost thing, so your best bet is to ring around as many garages as you can (even if you have to travel a bit).

I'm picking up my 406 Coupe on Sunday (if all goes well), and the cambelt/water pump change is the first major thing that will be done to it.

Probably the main power connector burned... common fault on D8s. Easy DIY fix - there's 3 philips screws holding the blower in under the passenger footwell (bit of a back breaker I'm afraid) and have a look at the connector on the end of the big thick red wire

Easily. Mine's up to something like 183k, and it put up a sterling performance on the Nurburgring a few months ago, and drives beautifully despite slamming it into the crash barrier at 90 PSA petrol engines tend to last forever no matter how much abuse you give them (as long as you don't start trying to increase the power output of course...)!

You are however coming up to the sort of mileage where a clutch change may be required. It's about £300 in parts and a good mechanic with the right equipment could just about get the job done in a working day to give you an idea of labour. I've done the job twice in my garage and would struggle to do it in 12 hours.

The kit is cheap enough, I gather;

Not on the V6 it ain't However it's not that much of a difficult job. The crankshaft pulley is even held on with little (13mm?) bolts instead of one huge ~25mm jobbie so you don't need several thousand NM of torque available to remove it

bennyboy200: make sure the crankshaft pulley is in good nick - the rubber bits tend to perish at this sort of age. I managed to get a replacement off ebay for £5 but I think the going rate is 30-50 quid. Also check the aux belt tensioner moves freely.

While I'm dishing out advice... There's a large metal oval in the air filter box, by where the oval inlet pipe attaches to it at the back. Remove this metal oval before it gets jarred out and sucked into the throttle body, jamming you at full throttle
