Good day to all... I'm looking for the correct way to get the lower water pipe into the pump housing. When I took it out, it had two rings - one at the end, and on in between the extrusions - where does it go really, and is there a trick to getting the pipe in?

You're likely to get varied answers on this one as this seems to be one of those questions that everybody seems to have there own take on.



Myself, all I do is push the 'O' ring onto the tube up to the first bulge, slap on a little water based lube or silicon grease and just push the tube into the coolant pump.



Clean inside the coolant pump's neck first and polish it with steel wool or a green scourer if need be.

Getting the water pipe into the water pump die-casting is one of the most difficult things to do on a CX/GL500. As Shep mentioned, use silicone or Plumber's grease to help get it back in. Also, if you use new o-ring(s) and they're not the exact proper size, they'll really fight going in.

My water pipe was fitted to the pump cover by a PO and wont budge !

gawd knows what they used to fix it on, but it doesnt leak so I leave it be

The down side of course is I have to remove it with the pump cover

but as its usually a related task its no big deal.

I had a hell of a time getting it in properly until I took the advice of others and used a bit of steel wool in the hole. Can't remember if I put the oring between the ridges or not.
