Fitting Decat..

[Pep]

Is it as simple as I think it will be?!

I take it I need no special tools, just my socket set and some brute force, or do I need to replace anything?
Going to fit a decat to my standard 182 system.

 

[DrR]

Hardest bit for me was getting the sensor out of the cat.

 

[MarcoB]

You might need a couple of gaskets and some exhaust paste?

 

[Brett]

WD40, an essential tool for any job where you are undoing tight or rusty bolts etc

 

[fossie]

Aye WD40 and some gaskets/paste and that will do the job... along with tools lol

 

[Pep]

Gaskets from where?
Sounds good.

 

[fossie]

Motor factors, renault and automotive place will do tbh

 

[Pep]

Not sure if i'm being stupid, but what gasket would I ask for at a motor factors? I know they all ome in different shapes/sizes etc, so just a 182 cat gasket set?

Sorry if the answer is blindingly obvious but I'm confused!

 

[DrR]

i didn't use any gaskets

 

[Henry]

you might need a grinder if the cat->system nuts/bolts are in a particularly bad way

worst case scenario:
- new manifold->cat fitting kit
- new cat->system gasket (best to renew this anyway)
- new cat->system nuts/bolts
- Loctite 5920 seems a good sealant if you still have blowing from the flange joint

got part numbers if you'd like them

 

[Pep]

Thanks Henry, part numbers would be awesome if it isn't too much trouble. From a quick peek earlier the bolts didnt look too bad, I'll get it up on my axle standas this week and have a look, might try cracking them off just to see!

 

[Henry]

no bother

- new manifold->cat fitting kit: cheapest from KTEC at about £20 (they're £40 from Renault at the moment..) but also check the link at the bottom of the post

- new cat->system gasket (best to renew this anyway): part number 7700823540 £4

- new cat->system nuts/bolts: bolt is PN 7703002949 (about £1); nut is PN 7703033132 (about £1)

- Loctite 5920 seems a good sealant if you still have blowing from the flange joint: about £5 from Halfords

A hammer for hitting rust?

 

[Nigel]

Hope you've got small hands. It's a pain getting a spanner and socket onto the spring loaded bolts from the cat to the manifold.

Rest of it is plain sailing.

 

[Mark One]

182, easy, 172 little harder (expect to bleed)

 

[Lagerlout]

It's a 182 so if all go's to plan it should be a piece of piss.

172's however....

 

[Cookie]

To seperate the cat from the mid section on my car, IIRC GDi had to get the angle grinder out

 

[Turkish]

Yup 182 = easy, 172 = right t**t.

As for WD40, when will people learn that it's s**t and it's not even a penetrating oil! you might want duck/mech oil on the lambda or some heat if it's stuck solid.

 

[Lagerlout]

Hot spanner FTW

 

[MarcoB]

Yup 182 = easy, 172 = right tw*t.

As for WD40, when will people learn that it's s**t and it's not even a penetrating oil! you might want duck/mech oil on the lambda or some heat if it's stuck solid.

+1
Btw ask for an exhaust gasket
You get a better seal and its easier to take off when a gasket has been fitted.

 

[Henry]

PlusGas is a better dismantling lube but it's expensive and not as widely available as WD40

 

[Pep]

Henry, legend!

Thanks for everyones help, hopefully I'll give it a go sometime soon!

 

[clio_rob]

a 22mm spanner will be needed for the lambda as well

 

[Christopher]

30 min job for me matey, the hardest bit is the oxy sensor.

I used a new fitting kit too... you can't go wrong!

 

[Pep]

Sweet, just topped up my toolkit today, some zip ties, superglue and epoxy resin, should be a piece of piss

 

[joebristolgym]

Easy for me when I did it -

22mm spanner for Lamda sensor
Socket and spanners to get off the 2 front bolts with the springs on them
2 bolts at the back with a band joining cat/de-cat to the centre section.

You might need a new gasket at the front, but you might get away with old one. It's like a wire mesh one that squashes down when you tighten bolts.

Suggest you will need exhaust past to join the back of de-cat to centre section.

That clamp was fiddly on mine, but just a matter of taking your time getting it off.

^ cheers mate, just pm'd you back.
