I have a 2001 Tacoma V6 (PreRunner) that is leaking coolant in such a way that's leaving me puzzled. There doesn't appear to be any coolant in the oil, no smoke from the exhaust, nor any visible coolant leaks. The water pump / timing belt were replaced 62k mi ago, with 185k on the truck. The one strange thing that has me confused is there is a noticeable amount of water leaking from the AC drain hose in front of the passenger firewall / wheel well area. However, this appears to be just water, and not coolant. Still, I find it odd that so much water (perhaps a cup) is draining over nearly an hour once parked since I'm not running the AC (only the fan), and only drive 10 or so miles. The coolant appears to leak as the vehicle sits (over the next 30 to 1 hour) after driving. I was curious if anyone had any ideas, or could lead me in the right direction. Thanks.
