Coolant is old.
An overflow tank is a bottle that holds coolant that expands and leaves the radiator under driving conditions. The Coolant will go back into the radiator as needed.
An overflow container prevents coolant loss. As coolant heats it expands. Without the tank, excess coolant would be forced from the radiator and be dumped on the ground. As coolant cools it is drawn back into the radiator so it always stays full.
in the overflow tank
how do I replace my 2005 fiesta expansion header tank
The overflow tank is either cracked or its overheating and leaking from the cap
The overflow tank for coolant will "boil" if there is air getting in the coolant chamber. This can be a head gasket going bad.
Its either in the coolant overflow tank or in the side of the radiator
Yes. There should always be some coolant in the overflow tank. Its level should rise when the engine warms up, and it should go back down when the engine cools.
Full to the level of the lower of the two lines that are molded into the overflow tank.
The system was overfilled and purged the excess coolant.
Add it in the overflow tank up to the max line.
Usually a blown head gasket.
coolant overflow/reservoir tank
Near the bottom of the coolant reservoir ( overflow tank)
coolant overflow tank. probably on top left side of engine towards the front.
The "check coolant level" message will come on when the coolant level is low in the overflow tank. If the message stays on after the tank is filled, make sure the sensor on the front bottom is connected. If the connection is O.K., then lightly tap on the side of the overflow tank with a soft rubber mallet. If the message persists after driving the car a couple of days, replace the overflow tank.
You add coolant to a C240 at the radiator overflow tank. This allows the radiator to suck in coolant as needed when hot.
You have to put it in the overflow tank.
thermostat or blown head gasket....
The coolant expands when heated, contracts when cool. The coolant reservoir gives the coolant a place to come and go as needed.
to the coolant recovery tank if so equipped - if no coolant recovery tank then not connected to anything - just an overflow
It will vary depending on the car. Coolant is in the radiator and the overflow tank is usually on one of the inside fenders. Usually on the opposite side from the battery.
