Citroen Saxo Engine Compartment Bolt Sizes

[raunchz]

Hiya guys,

I've got a bit of time to kill, and have noticed that a lot of people on here are having a bit of a nut and bolt fetish so thought I'd put up a listing of the engine bay bolts for the VTR/VTS - these are mostly the bolts that you can see in the engine bay plus a few others.

Let me know if you want me to add any bolts and I can do - maybe try and build up a nice list for people.

[bluenotesmiley]

Good info! This needs to be stickied really.

[141chris141]

vtr any chance

[raunchz]

vtr any chance

What year vtr?

You'll find you can't really replace too many of the bolts/nuts as they are all pretty special. Like the cambelt cover bolts are m6x1.00 but they have a smooth ring under the bolt head to helipad locate and hold the cover tight.

If you let me know what year vtr I'll see what bolts there are - howevervthe majority will be the same as above

[-Alex-]

2001 vtr, silvertop?

Cheers raunchz

[raunchz]

I've got a pretty intensive 2weeks of exams coming up but I'll see what different bolts the vtr has.

Everything will be the same apart from rocker cover (x2 M6x1.00 nuts with washers) and inlet (TBC)

when I'm done with exams I'll do one for 1.1,1.4 and 1.6 8v's although they'll all be basically the same so will prob do them all in one

[BobC]

[raunchz]

Good shout on the bolts.

[raunchz]

First post updated

any other bolts wanted?

[Lippy]

dude this is a fecking awsome thread! I asked you for this info only a little while ago iirc?

Could include links to companies that make Stainless, BZP, aliminium and titanium replacement items??? I like the pro bolt place you linked me!!! shiney shizzle!

On the bolt replacing fetish side of things I replaced the...
windscreen wiper nuts
nuts on the MC
the one holding the alternator power cable on
and the Strutt top nuts

they are all the same nut bit I dont know the dimensions...

I appologise in advance if some of these are included, i didnt read everything in the first post :)

[Lippy]

pro bolt are offering 2 different diameters of M6 washers on their site, im sure it will be 12mm diameter needed for JP4 covers though il be measuring tomorrow before ordering

EDIT : 12mm does the job fine for all of the bolts in question

[Olly]

Any idea on alternator bolt sizes mate? One long one short for vts

Wouldbe awesome!:D

[raunchz]

I know that the posts below were done a little while ago, but for completeness sake I thought I'd reply.

ProBolt are the only place that I know of that have such a huge range of different types of nuts/bolts/washers in different materials/colours etc. I'd stick to buying them from there tbh.

I've added the nut sizes above, all standard M8 nuts, just fit them with a washer if getting some fancy nuts.

Thanks mate, 12mm does seem a little large, but if they fit fine then all's good :)

I've got to re-install the Citroen software on my computer, once I've done it I'll update this post with the dimensions of them (even though you're probably sorted now :))

EDIT - LONG BOTTOM BOLT - M10x1.50 - 90mm long
SHORT TOP BOLT - M8x1.25 - 35mm long

[heyheyhey]

yeah sounds good

[J222JRA]

Very helpful guide Ross!!! Thanks

[jaym1806]

hi do you know the size of the bolts for the front seat subframes,rear seat belt bolts and lower rear engine mount

cheers mate

[StreetDragon]

Hello mates!!
You know a size the bolt on the exhaust manifold that attaches on the trasmission??

[JOEVTRR]

Rocker cover stud - Citroen 0250 60 - £0.29 + VAT each - x2 needed
Rocker cover cap nut - Citroen 0250 62 - £1.05 + VAT each - x2 needed

Just wondering the prices are on these but where do i get them from? citroen garage?

[NickB4]

This is a handy topic!

Maybe you could also add the bolt size for the knock-sensor on a TU5j4.
As the previous owner of my tu5j4 engine also made this mistake
The original bolt is a M8x1.00! not m8x1.25
I have repaired it with a helicoil because i hate it when the thread is damaged.

For the aluminium tu3jp (1.4 8v right?) it is m8x1.25 (not 100% sure).

[mangojace]

very handy

[azzasaxo]

cheers has helped

[Jim-Bob]

Ross do you still have the Citroen software,

If so could you find out what size the bolt is that attaches the seat belt to the a pillar high up?

I've stripped the thread and need to repair it, so if anyone can help it will be greatly appreciated!


Thanks

James

[raunchz]

I dont have the software anymore - might be worth phoning a citroen parts as the software normally told you the thread pitch and diameter alongside the part number.

I have a huge problem with one screw in the engine compartment.
I have a 1.1 Saxo and on the radiator there is a heat shield.
