The OEM paint coating on the disareator is known to flake off. Fortunatly, an easy and cost effective solution is to repaint using the correct black wrinkle finish.
Here’s a pic of a sorry looking disareator, you can see that most of the paint has come off the top:
A small amount of engine oil must be drained from the system. Open the rear drain plug under the gearbox and drain out some oil.
The disareator is held in place by three 13mm nuts located at the base. You also need to undo the two breather hoses and the thick oil line that goes to the oil cooler. Access is improved by moving the coolant tank out of the way but this is not necessary in order to remove. Here is a picture of a disareator on the bench – you can see the mounting points.
As the oil system is now open to the elements it is good practice to cover the opening.
The paint is easily removed using a chemical paint stripper.
Once all the paint is off, the inside and outside need to be fully cleaned and degreased. The surface should be keyed by rubbing down with wire wool.
Mask up the threads and parts that you don’t want painted. The wrinkle paint is best applied warm so let the disareator bask in the sun for a while.
It requires three thick coats:
After a few minutes in the sun the wrinkles start to appear.
For the best results, leave the paint to cure in a warm place for a week. Here’s what you should be left with once the masking has been removed. Re-fit to the car and don’t forget to top the oil up.
