It is recommended that the heater tap feed hose is changed at
40,000 km. (24,000 mile) intervals. It is important to ensure
that the flow through the heater hose connecting the engine to
the heater tap is completely unrestricted.

Restriction can be caused by a sharp radius or bend in the hose,
contact with other adjacent pipework, or poor alignment.
DESCRIPTION:
During seasonal servicing which franchise holders should now be
reconunending, ensure that the heater hose is at least 12.7 mm,
{0.500 inches) clear of any other adjacent pipework. If
necessary carefully re-align the hose to ensure these clearances
are correctly maintained and the hose is free from any sharp bend
or radius.
