3. Operation

Important: Read the Health and Safety information
before attempting to use this product. ALWAYS allow
the radiator to cool before removing the cap.

To avoid separation of the coolant solution, test the
solution while hot, after bringing the vehicle up to
temperature and then allowing the radiator to cool.

1. Run the vehicle engine to normal temperature if
necessary to mix fresh coolant.

2. Carefully remove the radiator cap using a cloth and
gloves.

WARNING! ALWAYS allow the radiator to cool
before opening it. The cooling system may still be
pressurised when opened and emit hot steam,
which can cause burns.

3. Insert the tester tube into the radiator reservoir and

squeeze the rubber bulb to draw uid into the tester

so that it is almost full.
Important: If the coolant solution is dirty or rusty,

drain, ush and rell the radiator, then clean the
tester and redraw the solution to the uid line.

4. Remove the tube from the reservoir and squeeze the

bulb lightly to expel any air bubbles from the uid.

5. Allow the discs to settle and observe the number of

discs that are oating (see below).

6. Flush the tester with hot soapy water and rinse clean
with warm water after use.
