G 20 3/4 Ton Van V8-379 6.2L DSL VIN C FI (1984)
Figure 1 - 1984 6.2L DIESEL FUEL FILTER
A fuel heater is an integral part of the fuel filter (Figure 1). The fuel heater is designed to come on when the fuel temperature is less than 4~C (40~F). It
warms the fuel and helps stop wax flakes from building up in the fuel filter.
If the vehicle is driven in temperature of less than -18~C (0~F) and Number 1-D or "winterized" Number 2-D fuel is not available, kerosene can be
added to reduce waxing. Kerosene should be added at a ratio of 1 gallon of kerosene to 2 gallons of diesel fuel. Because of the lower energy value of
kerosene (and reduced fuel economy), it should be added only when anticipated temperatures are less than -18~C (0~F). Once kerosene has been added,
the engine should be run for several minutes to mix the fuel.
NOTICE:
DO NOT try to use home heating oil or gasoline in the diesel engine. Either heating oil or gasoline may cause engine damage.
The addition of kerosene will not unplug a filter plugged with wax. Warming a "waxed" filter 0~C to 10~C (32~F to 50~F) will return the wax to
solution. Filter replacement is not normally required.
Also refer to the vehicle's owner's and driver's manual for additional information on diesel fuel and cold weather operation.
