smoking / overheat

Have you been making sure to keep the coolant system full?

There are only a couple places where it is likely to be coming from if it's pouring down the exhaust and they're all right in front of the fire wall on the passenger side. On the up side, they're not all terrible to get to, on the down side, there is one 90? hose behind the head which is miserable. Hopefully it'll be one of the heater hoses, a crack in the heater control valve or the rubber plug on the metal pipe which peaks out from behind the engine. The Head gasket is a possibility, but I think a hose is more likely.

If you can't spot the source of the leak by hand or feel then go get a pressure tester and have at it.
