Hey Guys,
 I changed the coolant in my car recently, and now have the top air bleed valve leaking coolant all over the darn place.  it's definitely leaking out the front radiator coolant air bleed valve (the one on the top next on the passenger side). Being a 21 year old car I'm fairly sure that the o-ring would be toast (and maybe the sealing surface too).
 
Does anyone know the parts I need to replace? Ie tap and o-ring?  I can't seem to find an EPC (or just a straight PDF one) for help :(.
 
thanks in advance.
H.

edit - I'm mega short of time atm - and driving with a leak is bad. sorry if I'm missing something particularly easy to find. :(

ok I'm a bit retarded found a guide and looks like it's a standard toyota part - http://opc.mr2oc.com/online_parts_catalog/Cooling/radiator-water%202.GIF
 
but toyota call it "packing" is this an o-ring? do I need one or two?
 
blah I think I need to go home and look at this :\

I just got an misc o-ring pack from Repco. Had a few that did the job.

awesome - thanks - I'll get dad to pick me one up during the week.... :) (I'm off to QLD for the next 4 days.) 
 

Yeah a repco, burson, supercheap one that comes in various sizes in a box will do it, thats what i did one of them will fit lol.
mine also broke/cracked when i tried to bleed the coolant the first time.
might as well change the bottom one but for you it will ahve to next time you drain the coolant.
