Engine confirmation request

[moizeau]

Could someone (Marc) please confirm that the engine in my C4 is an RFN. I've got my mates 307 Revue Technique but this shows the procedure for the RFJ. I've compared the cam belt procedure in the Resources Guide to the book and although different variants it seems to be identical. From what I've read the RFJ is the same engine but with a VVT suffix, upping the BHP and Torque a tad while improving fuel consumption. I'm guessing VVT stands for Variable Valve Timing?
Thanks in advance

The engine code is part of the VIN 6th to 8th digits.

Hi Pete, yes for your C4 VIN ending 659, you have the EW10J4 engine and the RFN variant. The engine code variant is contained in the VIN (characters 6, 7 & 8).

VVT does indeed stand for Variable Valve Timing.

The RFJ variant has 105 KW Power and 143 HP, the RFN is a 100 / 138 version.

Be aware that some timing components are different between the engine variants.

If you want a guide on replacing the timing belt, let me know and I'll put something up in the Members Resources section for you.

Thanks Wheeler and Marc. Didn't realise that regarding the engine variant, very useful to know.
I think I've found the cam belt bit in the C4 2005, page 209 of the handbooks topic. Thanks for the offer all the same Marc.
What I would like to know is the size of the pegs for locking the engine. The cam pegs look like a couple of bolts would do but the flywheel one looks stepped. If someone knows the sizes I have a mate that could get one turned at work. Also it doesn't mention any other tool to lock the engine whilst undoing the crank pulley bolt so I'm guessing the flywheel locking pin is heavy duty enough to do both jobs? I suppose most mechanics just use rattle guns.
Cheers

Although I have a procedure up for the EW10A engine Pete, I think I will put a guide up regardless as it's a bit involved with the angular tightening etc., and the pins are slightly different for the EW10J4 engine, so I'll put a link here for you when I've completed it in about 30 mins or so.

Here you go Pete:

There are a couple of variants of the EW engines & if its the flywheel pin that has quite a big step in it just beware this engine has a floating crank pinion with no woodruff key if you loosen the crank pulley bolt without pegging it properly you can get in a right mess with the timing.
There is actually a separate heavier duty flywheel Lock for loosing the crank pulley that looks very similar to the setting peg.
EDIT: this kit has both the setting peg & the thicker loosening peg.

Thanks very much Marc, that confirms what I have read. The tool 189r seems to do both jobs, position setting and locking to enable the bolt to be removed. I'll have a word with a mate who has a garage and has lent me tools before.
I take it the pulley bolt is 'kin tight? Feasible lying underneath with a decent bar or borrow a rattle gun to get it started?
On the XUD9 and 10 I used to use the starter motor with a big rag wrapped round the socket.

I will mark the old belt, crank and cam pulleys, then transfer the marks to the new belt. Always done it, just gives me peace of mind and helps when you find yourself in the 1/2 a tooth that way or the other way scenario.
Thanks again
