I had to go to the dealer for one. I used an aftermarket water outlet that leaked at the bleeder o ring and 1 month later the outlet o ring leaked as well. I ended up buying oem ac delco and no problems. I ended up putting some teflon tape around the bleeder tube about 6 wraps an that was enough to swell the o ring to get a good seal.
