to the coolant recovery tank if so equipped - if no coolant recovery tank then not connected to anything - just an overflow
the top hose on top of the tank is to allow any overfill to escape. Any fluid will just flow from the hose fitting and down the side of the tank.
On a 1995 Cadillac Eldorado, the hose from the overflow tank typically connects to the radiator or the coolant reservoir. This hose allows excess coolant to flow back into the system as it cools down, maintaining proper coolant levels. Ensure that the connections are secure and free from leaks to prevent overheating issues. Always refer to the owner’s manual for specific routing and connections.
Follow the small hose from the radiator. It goes to the recovery tank.
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.
remove the two 10mm nuts. dissconnnect the coolant level sensor plug and remove coolant hose's
1. raise gas tank, the radiator cap is there, below the gas tank, open the cap... 2. remove the drain bolt on the water pump cover and drain the system coolant.. 3. disconnect the hose from the reserve coolant tank, end empty the coolant from the reserve tank, and after that connect the hose . 4. re install the drain bolt n fill the coolant from radiator cap, the drain bolt potitions on left side under the engine.
a crack or a hole in the tank. or hose for that matter
The gas tank.
drain out coolant to a point were hose is clear, remove hose then replace,add coolant to bring up to normal level...will loose a bit of coolant but not much!!
The plastic tank is held on with a single bolt.It's below the tank toward the front of the car. Use plyers to slip hose clamps off.
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.
