I'm guessing it would be fine if it's been used like that before.

If I were you though I'd try and run it how it was originally. I picked up a load of extra pipes from a local motor factors to plumb mine in :)

Hello... ^^^^ any answers to my question?

just found this thread after searching around about my coolant hoses so sorry about bringing up an old thread...

the hoses from this joint on the throttle body


one goes to the rocker cover, the other two on my engine (by previous owner) have be chopped and blocked with bolts.

then the bit on the manifold near the alternator has been chopped and blocked also like so


as for the last one from the throttle body, this thread says it goes to one of the upper expansion bottle ports but i have a hose there which joins to the big hose going to the bottom of the expansion bottle

is this bad/important?

yeaa i took my plug out the end of the hose tonight and blew down it and it bubbled back up in the header tank so yea thats got to be connected back up, and yea iv got both i did have the one with two but then swapped it to the one with one as didnt know where it went but now i'l have to swap it back, i'l do it now as iv found a few more problems with my engine, cracked sump so im in no rush but cheers anyway for the info very helpfull

One of them goes to number 1 in this pic mate, and the other goes to the header tank :thumbs:

It should go to the tank yea. If there isn't one on there ya.

Do you have to 16v header tank with the 2 outlets? Or 1?

ah right, hmm god knows what im thinking of then, i'l have a look 2moro afternoon when i get back from work, but iv got two pipes at are joined togeather as such side by side that come from the under side of the manifold somewhere, and the one pipe is connected but dont know where the other one goes to so i plugged it up with a bolt, is this the other water pipe thats supposed to go to the header tank then?

There water cooled inlets anyway?

ah right so thats where that goes? but one question water breather pipe to inlet manifold?? that doesnt sound a good mixture....

Yea that's the one. Should have 2 pipes coming from the iirc.

Cheers for the info mate, think I know where it goes now, think the previous owner has plumbed it up wrong which is whats confusing me :facepalm:

Someone on Mig gave me this pic,

The pipe your referring to Jamie that you have to the heater matrix is the water bar (Long black pipe the runs on the back of the block)

The pipe your after leads onto the back of the inlet tucked up underneath iirc. My pipe looks different to most because I hadn't been assed to tuck it back under the inlet again. Because I needed to take a few bits off. But it does go round the inlet bud.

No Dan I couldn't find anywhere for it to go in the area you said, starting to confuse the hell out of me now.

Darryl the pipe that goes around the block, there's two outlets on that, I have one of them going to the heater matrix and the other is going to the bottom of the expansion bottle.

Kieran's in the first pic has had wires hidden and hoses rerouted if I'm not mistaken, quite far from standard anyway

Take it where Ash's went yours didn't?

I don't then Jame.

Kies looks different to mine. On mine it goes to the pipe that comes round the block and the other goes to the top of the rad :boggle:

edit you can see mine vaugely in the direction it goes here

on the inlet manifold in the centre there will be a breather that goes to the rocker. either side of that will be 2 hoses. one goes to where u said the other goes just above the alternator

Left hose on the expansion bottle, goes along the bulkhead. Then where?

Done the plumbing on my Corsa XE, got one pipe left that I can't find where it goes, its the left outlet on the expansion bottle. I've looked all over the inlet manifold but can't find its home, can anyone shed any light?
