Recommendations
When diesel fuel is subjected to low
temperatures (below 21°F or -6°C), par-
affin wax particulates will form within
the fuel which will eventually create
blockages in the fuel system. To mini-
mize the risk of fuel
‘waxing’,
it is rec-
ommended that the following
precautions are observed:
• The use of winter grade fuel will
give added protection to the fuel
system during cold weather condi-
tions. Ensure that the vehicle is
using winter grade fuel in anticipa-
tion of cold weather conditions.
• In the event of the fuel waxing, it is
recommended that a replacement
fuel filter is carried to enable a
blocked filter to be replaced; wax
particulates cannot be dissolved by
the application of heat.
• For extreme and prolonged cold
weather conditions, it is recom-
mended that the vehicle be
equipped with a heated fuel filter
and that all fuel pipes and fuel
tanks are adequately insulated;
refer to your dealer for further infor-
mation.
