Cooling
System
Frost
Water expands when it freezes, and if precautions are not taken there is consider-
precautions
able risk of bursting the radiator, cylinder block, or heater. The heater unit
cannot be drained with the cooling system; it is therefore essential to use anti-
freeze in the cooling system in freezing conditions.
We recommend the use of
Bluecol U universal
anti-freeze to protect the cooling
system.
If
Bluecol
U
universal is not available any anti-freeze conforming to specification
B.S.
3151
or B.S.
3152
may be used. Anti-freezes to these specifications are
compatible with Bluecol
U
universal and can be used with it. Bluecol
U
universal
should not be mixed with other universal anti-freezes.
After filling with anti-freeze solution, attach a warning label to a prominent
position on the car stating the type of anti-freeze contained in the cooling system
to ensure that the correct type is used for topping-up.
Anti-freeze can remain in the cooling system for two years provided that the
specific gravity of the coolant is checked periodically and anti-freeze added as
necessary. The specific gravity check should be carried out by an authorized
Distributor or Dealer. After the second year the system should be drained and
flushed by inserting a hose in the filling orifice and allowing water to flow through
until clean. Make sure that the cooling system is water-tight, examine all joints
and replace any defective hose with a new one. Refill with the appropriate
anti-freeze solution.
The recommended quantities of anti-freeze solution are given below.
Do not use radiator anti-freeze solution in the windscreen-washing equipment.
Use the correct washer solvent, which will not damage the paintwork.
