3. Use of incorrect fuel will cause the fuel to wax/thicken. This will block filter elements and increase wear in
the fuel injection pump and injection systems. At extremely low temperatures trace heating may also be
required to prevent the fuel from thickening and waxing.
4. If the engine block heater is not used then the engine may have problems in cold starting. Combined with
incorrect coolant mixture will lead to cracks and damage to the engine crankcase or cylinder head due to
freezing of the water mixture.
5. Freezing of the condensate within the CCV filter and breather pipe may also occur if the combined
extremely low ambient temperature and subsequent air flow wind speed reduce the temperature around
the components to a level that the condensate freezes. Moderating the airflow using actuated louvers on
the air intake and raising the under canopy temperature helps prevent freezing.
6. For the main alternator, if Anti Condensation Heaters (ACH) are not installed, then in cold climates
condensation can form on the windings and electronic AVR boards.
7. This condensation can cause tracking and short circuits of components and subsequent failure. The same
can happen inside the control panel and related circuits.
8. To prevent condensation on the alternator and control panel, an Anti Condensation Heater (ACH)/auxiliary
canopy heater may be required.
9. Failure to protect the batteries from the cold climate can also cause premature discharge of the battery
voltage and give problems with the engine cranking speed.
