This system is often neglected and stops working. If you have an idle afternoon why not get it going.
You will need:
- Silicon based oil (Tip: You can use shock absorber oil for a radio controlled car such as made by Tamiya)
- Toilet Roll
Instructions
Don't use brake fluid whatever you do !!!
You need to take the adjuster next to the drivers seat apart, it is quite obvious how to do this when you look at it. Inside there are two plungers, like little pistons, which push the fluid down the two pipes. The weight of the headlamps / springs on the headlamps will push the fluid back.
What you need to do is get both pipes full all the way to the headlights. If you raise the lights and remove the covers (three screws on each) you will see a rubber connector where the white (usually) tube connects to a piston chamber behind and below the headlight. This is where you can bleed the fluid.
The fluid used is a silicon based oil and you can use shock absorber oil for a radio controlled car such as made by Tamiya. This is available from any good model shop and is not expensive. If they have several grades get the lightest weight one. It's usually green or gold colour.
All you need to do is get the pipes full of liquid with no airlocks. You can use the little plastic bottle that the oil comes in to squeeze it slowly through until it emerges the other end and moves the headlight. Can be a messy job - have a roll of toilet paper ready, you don't want that oil on your carpets / seats.
