Hi everyone

I have just bought a y reg 1.9jtd multipla and want to do an oil change tomorrow.

Got the oil, flush and filter but i cant seen where the drain plug is?

Any help on the following would be greatly appreciated:

1. Size of tool needed for drian plug?

2. Location of drain plug e.g. 50cm back from centre of bumper and 50cm towards the passenger side??

Many thanks

The drain plug should be (if it's like my W-reg) on the back lower edge of the oil sump. It's a relatively large hexagonal affair with a big allen key (hexagonal) hole in it.
You could use a socket to undo the drain plug or a large allen key. I purchased a Fiat drain plug key from my local accessory shop. It has 10 and 12mm allen 'keys' on each end.

Tip - run the engine for a few minutes first to warm the oil up or take it for a drive for a mile or so. It'll run out faster than if it's cold and more sludge will run out with it. Have plenty of newspaper/rags handy for any spillage though and wear rubber/latex gloves. Diesel oil stains very well!

sorry if i'm being stupid but.....the sump being the big silver lump on the drivers side just back from the oil filter?

thanks for the help

also........as i'm lying on the floor facing the underside of the engine does the drain plug jurn anti-clockwise to undo?

thanks again

Yes the sump is the one on the driver's side with the flat (sloping) bottom. The uneven one on the passenger side is the gearbox.

If you're laid on your back looking up at it - the drain plug will undo anti-clockwise. Just turn it with the socket enough to loosen it and then do the rest with your fingers. Keep pressure on the head of the bung while you're undoing it. When the plug stops coming out of the hole and just turns without doing anything - whip it away - don't drop it into the bucket or you'll end up fishing around for it. A new sealing washer is usually recommended but not always neccessary if the old one looks Ok - but for a few pence - replace it.

Really appreciate the help

Many thanks

10 or 12mm Allen key ?

Will a T40 Torx do it as well ? Chimpanzee I bought the car off has overfilled the oil and I need to drain ift off

Slightly wary of a sump that looks overfilled. Do the oil change as recommended, check the oil level using the dipstick after running the engine to fill the oil filter (let the engine rest for a couple of minutes before checking the oil level). Make sure it's approximately halfway between the low and high marks (add more oil if it's low) then use the car for a month or so. Diesel engines have a problem that petrol engines don't have. Worn piston rings can allow unburnt fuel to find its way into the sump, especially on cold starts and diesel fuel doesn't evaporate the way petrol does, so a build up of diesel in the sump can make the oil level rise. I'd check the level again after a month or so; if it's higher it indicates worn piston rings. Not a major problem for cars used mainly for long runs as the hot engine tends to seal the rings but if the car is mainly started cold for short runs, worn rings can let quite a lot of fuel into the sump.

What to do depends on how deep your pocket is. To cure it properly, worst case could be a major overhaul (engine out, cylinders re-bored then oversize pistons and rings fitted) but if you're lucky the rings might be OK; just gummed up and sticking in the grooves in the piston, again this can be caused by a lot of short runs. There are solvents that you add to the fuel, available from both D & A and Halfords; be worth a try? Even if the rings aren't gummed up, used occasionally these additives do no harm..................

Decided to get it serviced rather than pee about with it myself, neither got the time or the patience

Hopefully I haven't bought a pig in a poke and it is just simply overfilled

Thanks for the advice, I'll let you know what happens at the service!
