Pontiac: '97 Bonneville coolant leak

'97 Bonneville coolant leak
I have a coolant leak on my '97 Bonneville (no supercharger) but I'm not
sure where. There is a spray pattern from the accessory drive belt on the
underside on the hood. The engine mount brackets behind and below the water
pump are wet, as well as the front and back of the ignition control module.
It didn't leak onto the garage floor overnight, and it didn't leak when I
observed the car running for a few minutes (the car was warm at the time).
Is there a hose hidden somewhere that I can check before replacing the water
pump (there was a little dinky one in that area on my '91 Ciera)? Is there
something I can do to help identify the leak?
Thanks,
Joe

There is a hose under the alternator connecting the pump to the
intake manifold. It has a "plastic" hose nipple threaded into the
manifold. These nipples often crack and leak. The hose can also
deteriorate, but the fact it does not leak onto the garage floor
overnight points me to a bad water pump seal.

Re: '97 Bonneville coolant leak
your water pump is bad. It has what is called a weep hole on the underside of the pump to let you know it's bad before it goes out completely.

How much longer could it last?
