It's steam from boiling coolant (or water) coming out of the overflow hose connected to the top of the radiator just below the level of the cap.
The hose that goes from the overflow to the bottom of the radiator on a 2002 Windstar is the bypass hose. It allows coolant from the overflow to return to the radiator as it cools.
Spilling water from where? Then it has a leak or is overheating. Find the location of the leak.Mine needed a hose clamp on the overflow hose at the radiator,
This is probably an overflow pipe from the cold water tank in the loft.
That device is called the refill tube. This allows water to go down the overflow tube to refill the water closet bowl while the tank is filling.
too much water added the overflow is designed to let out water.onece the radiator reaches the required pressure,the excess water is exhausted thru the overflow
Turn the hose off
Actually, this is an overflow hose. The hose shouldn't connect to anything. When the radiator warms up the fluid level in the reservoir tank may rise. If it gets too high, then the coolant will pour out of this overflow hose. If this is happening too often, you may have a blockage in your radiator.
On a 2003 Bonneville, the hose to the water pump that is the heater inlet hose is the top hose coming from the radiator. This is also the hose that holds the thermostat.
water pump (has a pin hole overflow if goes bad) , water hose connection, overheating, damage to the radiator causing a crack?
the drain hose is plugged
the reason for water coming out from under the dash is that a hose could have broke or you have a problem with your heater. your heater works off of the water in the radaitor and since it gets hot from the motor well it serculates threw the heater and that's who your heater works
