Oil in coolant overflow tank?
Usually a blown head gasket.
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.
Does low coolant level and no pressure in the overflow tank mean coolant is leaking into the engine in a 98 olds intrigue?
Technically, there is no fill cap on the radiator. To add coolant, open the overflow tank. It should be on the Passenger side fender, next to the windshield fluid tank. The coolant tank is pressurized when the engine is hot. Be very careful removing the cap to the coolant overflow if the engine has been running, since the scalding hot coolant can burn you.
It has a tube between itself and the radiator. As coolant heats up, it expands. The expanding coolant goes through the tube into the overflow tank. Later, when the vehicle is shut off and the radiator cools, the overflow is pulled back into the radiator. The system is "closed", hence the coolant does not just "dribble away" when it expands like it did in vehicles many years ago.
coolant recovery tank? Mount recovery tank in location as to not interfere with any engine moving or heat producing parts - perhap on fender well or firewall. Take overflow tube from radiator neck to bottom of recovery tank Fill recovery tank with coolant Run overflow from recovery tank to atmosphere making sure it does not interfere with any moving engine parts
Don't worry about it, just close the lid and the automatic filler will prime it eventually. Most newer cars are self-purging. Keep coolant in the overflow tank and it will 'burp' out the extra air once the engine comes up to temperature. When it cools, the system will suck coolant out of the overflow tank to make up for the air that got 'burped' out. You'll know it is working because the coolant level in…
It could be a couple of things. The coolant system could be over full. There could be a clog in the radiator. Or possibly the thermostat but not likely. also, the ford coolant tank is pressure sealed, if the cap to the tank has a defective seal, it WILL overflow when you stop your car, or whenever the pressure builds
If starting from empty pull the top radiator hose off the engine and fill the radiator until coolant starts to flow from the engine hose bib. replace and tighten hose. Fill the overflow tank with coolant. Locate the vent on the coolant hose bib (brass fitting), start the engine and allow coolant flow to purge the air from the system. When coolant flows steadily close the vent. Re-top up the overflow tank.
