Where's it leaking from?

Usual culprit on V6s is the HBV at rear of plenum.

Heater Bypass Valve - sits behind plenum drivers side - you can just get your hand down to feel for wetness - there are 3 water hoses connected plus a vacuum pipe on top.  Looks like Starship Enterprise!!

On TC card I paid just over £30 for genuine Vx one recently.  Do NOT buy the cheapos off ebay - they will leak.

Fiddly to swap - look here for howto - http://www.omegaowners.com/forum/YaBB.pl?num=1193594464
