just a hollow plastic/brass tank, that joins the radiator tubes to the bottom tank. they hollow so water can flow in and out of the tubes in radiator.

what the top hose joins on to..

know where i can get one cheap but good?

the fixed pipe on the top of my radiator came off inside the flexi-pipe. dunno what to do about it ?

[kingcorolla]

easy! dont get a new tank.. just take it to a radiator specialist, and get them to weld it back on!

If its a plastic you cant weld it and you need a new tank $200+ or get a s/h radiator.

would plastic welding not do the trick???

[blitza]

can do, not many ppl would be keen to do it but, can't provide any warranty.

[Sanxta]

yeah, prolly keener to do it properly with a replacement brand new.

what do you mean by "s/h radiator" ?

second hand

[Sanxta]

oh yeah *duh* @ me

um yeah, pretty dodgy considering cooling system water skankiness . . .

[kingcorolla]

.. just drop it off at the doctors before u put it in then..

save ureself from getting a R.T.D (radiator transmitted disease)
