Want this question answered?
the operation of a expansion tank?
No, an expansion tank is not required.
A fuel solenoid is part of the fuel tank in a Vectra B DTI vehicle. The fuel solenoid itself will be located directly inside of the fuel tank. Vectra is a car made by Opel.
It is situated inside the fuel tank itself. Vectra B that is. Do get to it you will have to lift the back seats up there is a plastic lid you can take off then disconnect the two outlet fuel pipes and electri plug then unscrew lid and ur inside the tank. Swirl pot is inside.
Allows for expansion and contraction of various systems
i take it you are talking bout expansion tank on a/c this is evaporation and is common on all vehicles if you are talking bout expansion tank on radiator, you have either got to much coolant in radiator,(check level when cold) or you have an air lock in the cooling system and need the system bled to remove air
It is just a expansion tank. Henry
There shouldn't be just water in the expansion tank. If the coolant (50% anti-freeze and water) appears to be boiling in the expansion tank, you may have a bad head gasket or cracked head.
to circulate water in fresh water tank to expansion talk.
Top up with correct water anty-freze mix, take cap off expansion tank, turn on engine and allow to idle for 3 minuets or so, you can watch the bubbles coming up in the expansion tank. strongly massage the return pipe, big pipe on the top of the rad left side as you face it, coolant should shoot into the expansion tank as you do this. once it is cool check if you need to top up coolant mix and off you go. ps do not take the cap of the expansion tank when the engine is hot.

Unless I have drained the block and radiator, I have filled the radiator from my expansion tank in every vehicle I ever had. If you have drained your radiator and it is cold, take off the cap and fill it that way. If you have drained the engine block and have not change your thermostat, you will need to keep filling your expansion tank until everything is filled back up. I recommend changing your thermostat.
