Re: No Heat :hot water valve?

Sounds like your thermostat may be stuck open. Hoses to heater core
should be too hot to handle. The flap in the dash doesn't control
water -- only allows air to flow over heater core (a little radiator).

Do your big hoses get hot? If not, thermostat's definitely stuck.

Note that engine needs to be WARM to operate efficiently (that's why
thermostat's there rather than just a giant hose barb).
