Sigma Oil Change - Parts


Jim 123

Recommended Posts

I'm looking to do a first oil change on my 1.6 Sigma and would appreciate advice on 4 topics:

Ford service manuals state that the Sump Plug should be changed when the oil is drained down.  I know that the Caterham Sump is a different casting, but is the Sump Plug the same on our Caterhams as the part that goes into a Focus Sump?

Also does anyone know the Ford Part Number for the Sump Plug?

What is the tightening torque for the Sump Plug?

Lastly, can anyone advise the Ford Part Number for the Oil Filter for the 1.6 Ti VCT engine?

See my thread here asking pretty much the same questions:  http://www.lotus7.club/forum/techtalk/sigma-sump-drain-plug

I've never bothered changing the plug, and its really not necessary unless it is damaged..  I do however change the rubber o-ring/washer.

This article explains the different plugs. (Its the SP3 on my Sigma):  http://www.ebay.co.uk/gds/How-to-know-which-sump-plug-my-Ford-engined-vehicle-takes-/10000000178114024/g.html

I buy the washers from the same shop:  http://www.smartearlybird.co.uk/ford/

Oil filter is here:  http://www.fordpartsuk.com/shop/ford_focus_oil_filter_2011_onwards_f_1883037.htm

I've come to the conclusion that something like a sump plug is better done up by hand rather then torque wrench.  I've stripped far more threads trying to get them to some predetermined value rather than going by feel and using common sense.  It really doesn't need a lot of torque - it is the rubber that seals it.  If it leaks after you've filled it up then give it another 1/8th turn.  But I've never found that necessary.

The Haynes manual for the Sigma engine states 28Nm for the sump plug, and I've been using this for 5 years without problem.

I always change the rubber seals on the plug as they are cheap and it's a pain to have to sort out a drip afterwards.
