What Is This ?

[Guest rambo]

hi all,

noticed on my car today 2.0 galaxy 1996 a plastic cylinder with 2 pipes fitted to it and the bottom of it has come off seems to just clip back into place but it wont stay connected i could super glue it on i reckon, what is it for ??????

 

it all joins to a round plastic unit, which is below and to the left of the water bottle (battery) i think it has something to do with the egr system but i dont know ?

 

dam hard to explain

 

1 pipe leads to another round plastic looking canister with a filter in the bottom of it, the other pipe goes to the egr valve (this is the one where the bottom of the canister has come off, has a rod in the centre when i press hard to try to clip it back on you can hear air being pumped :lol:

Errr? Can you post a photo??

desparate guess - anything like this

 

[Guest 3.5bullet]

The large round unit you describe sounds like the secondary air pump? so you the part that has fallen apart does indeed sound like a valve for the erg system?

[Guest rambo]

thanx for the replies so far, i will post a pic this evening

NIKPV looks something like your pic, probably is that but an older version ?

[Guest HairyPlateEater]

Niks photo is of the cruise control vacuum pump and is located in the n/s hollow wing cavity on the mk1 or by the radiator on the mk2 IIRC

[Guest bigal]

On my mk2 its still between the wing, but mine is an early one.

[Guest rambo]

this is the offending part

between battery and coil pack

Could it be this

 

 

Secondary Air Injection Switching valve ???

WELL DONE NIKPV :lol:

thats exactly what it is, shall i just super glue the bottom of it on then as it just wont stay clipped on, i dont know why none of the clips are broken off, what does it exactly do ??? does it affect performance or fuel consumption ?

 

cheers all :wacko:

I think it reduces the amount of unburnt hc's in the exhaust by pulsing air into it so stops the cat being 'poisoned' allows enough oxygen for oxidation. and I think has something to do with cold starting
