What tool for the MAF screws?

[mrdavies]

Hi all so im going to clean my MAF at weekend as car seems to be hesitating and revs fluctuating .

but what device do i use on the awkward screws connected to the MAF housing ? and will i need a new metal clip?

 

[Guppsta]

I bought an anti tamper bit set from eBay,it was about £10 and it's got loads of dodgy bits in including the one you need

 

[Phillc]

Maplin also sell them.

It's a tamper proof torx bit iirc. Not sure what size though, maybe T15 or T20.

Which metal clip do you mean?

 

[sambryant]

get a hack saw and cut a slit in both screws, then use a flat head screw driver to undo them.

 

[andycupra]

screws as above. the other end you are probavbly referring to the once fit clips?
These usually get ruined when removed so get a large jubilee clip.

 

[rk696]

The spring clamp on the intake hose can be removed easily enough with a pair of mole grips or similar.

Just don't let it spring from the jaws as it's a major PITA to compress it again, as the tabs go really far apart.

Jubilee clip is better though.

 

[andycupra]

aha, yes it might be a spring clip. easy.

i used some mole grips on the screws. worked a treat. didnt have spring clips so maybe it was changed recently. it was very clean so probably wasted my time but had a sense of achievement after donig it!

ye its like a round circle clip that connects together just a standard metal clip so ye a jubliee will be better i suppose . are theese tools hard to buy? will look in maplin see what they have also only work round corner from a maplins.

good idea with the hack saw tho lol if i struggle finding a tool that sure is the next plan . thanks all for you quick input greatly appreciated . roll on friday when im off will get to work on it . thanks

Your welcome mate

ok got the tool , got the cleaner from maplin , ready to give it a clean at weekend and change my front discs n pads. how did you get the nig metal spring clip off ? really stiff or can the sensor and housing come off withought moving the big standard clip.

 

[mrdavies]

job done. seems a little better can not fully comment yet but easy job and no hesitation as of yet and steadier revs.

I did you go by the guide from what was from: http://www.seatcupra.net/index.php?option=com_content&task=view&id=517&Itemid=6
As I'm looking to clean my MAF as my LC's fluctuating on rev's as well any tips when I come to do it?

get a T20 anti tamper screw bit saves lots of time. by some electrical solvent cleaner from maplins 3.99 . when you go to unplug the sensor from the cable it was really stiff , just pull it you will not break it. i had to pull with some force to get it off. if you are cleaning the housing and the sensor i would still recommend taking the sensor out. spray all over it even in the grooves. wipe over with lint free cloth removing dirt. spray again and wait till sensor drys. as for the housing unscrew bolts from pipe , take clip off pull with small ammount of force it will come out eventually. spray all through the housing on both metal parts. same rule wait till it dry's. then put the housing back and re screw it all back in. then put the maf sensor in last. and re attatch cable/plug. then good to go . just be gentle when cleaning as it is very easy to break i belive.

Are we sure this is a T20 security bit. I have a set and none of them fit. I'm sure the screw is a 5 start when the torx are 6?

Anyone got a link to the extact tool they used?

Cheers

I just used a pair of pliers to grip the outside edge of the screw and undo it, granted it's by far the proper way of doing things but it worked fine.
