Thanks for the guide, but I am not sure about this torque value.

For the Punto Evo 1.4 8v VVT:

Fiat Elearn says 1.8 to 2.2 daNm (this is 18 to 22 Nm) + 55 degrees.

and the new Punto Evo Haynes manual says
stage 1) tighten to 20Nm,
stage 2) tighten a further 55 degrees.

my / sealeys mistake ive just checked on elearn

However i was going by the figures on my cam locking kit from sealey and it does give 180-220nm me thinks i avoided a very expensive mistake by the skin of my knuckles...


i have amended the guide accordingly

They certainly did. I would have expected better from Sealey.

Glad you break anything

Re: 1.2 8V EVO 2 Engine Cam Belt replacement

Does anyone have an Amazon / Ebay link to where I'd get the Cam Lock kit from for the 1.2 8v 2006 Grand Punto? or is it a Universal Jobby?

Re: 1.2 8V EVO 2 Engine Cam Belt replacement

Thanks for the guide as i will be attempting this soon.

I have a question though - what is the need to slacken off the cam pulley - i.e. this bit;

"next slacken off Cam pully
FIRST REMOVE CAM LOCKING TOOL or you can damage your camshaft end

loosen using a 24mm spanner on the flats on the cam shaft and a T55 torx socket)
"

Surely if the you've managed to get the locking tools fitted to the cam and crankshaft there is no need to touch the cam pulley as it should already be set?

Or am i missing something?

I have done a Vauxhall 1.6 engine before but i would just like be sure before i start.

Cool Re: 1.2 8V EVO 2 Engine Cam Belt replacement

1. Yes, that doesn't make sense, to "slacken off the cam pulley". No need for that.
Some folks do it (probably) just because it is inconvenient to put new belt on ("thread" it around all pulleys).

2. You don't need special tools. It still can be done classic way (marks, magic marker/sharpie, paint), a bit harder, but doable. Also no need for "special" alignment tool for camshaft cover.
Russians do it like this (part 1, belt removal):
and part 2 (fitting new belt):
don't listen just watch carefully.

3. And no one even tried to copy timing belt tools? Looks like an easy bolt hole pattern, and linear dimensions are not critical (angles are - that's the main purpose of locking tools/jigs).

Camshaft locking tool seems to be exactly 10 degrees (most important number here), rest you can figure out by yourself...

Reverse engineering based on pictures works pretty well. Nice round numbers pop out.

You can also guess accurately dimensions if you try.

To make yourself a copy, use flat-bar, no need for "lollipop" shape. Holes can be slotted (so you don't worry about accuracy, at least in terms of linear dimensions - but mind the "clocking").

Guess what. It's a FIRE family. Some things ain't change. This is crank pulley/cog from Punto 1. Same dimensions. Only number of tooth differs.

Everything fits, same numbers (Punto 1 = Grande locking tools dimensions extracted from pictures).

Bolt hole pattern is...you guess...the same. Measurement and some math.

So, you get the idea. Using basic metalworking/machinist skills (layout/scribing, drilling, filing) you can attempt making your own "timing belt kit" set. No rocket science.
