At reduction of temperature viscosity of diesel fuel increases, due to hardening of the paraffin which is contained in fuel. Therefore additives which reduce viscosity of diesel fuel are entered into fuel and allow to make start of the engine at low temperatures. On the Vectra cars the electric heater of the fuel filter which, warming up fuel, excludes hardening of particles of paraffin in fuel is established.
The heater of the fuel filter is located between the fuel filter and the holder of the filter. The sensor constantly takes temperature of the fuel passing through the filter.
Disconnect the electric socket from a heater, remove the fuel filter and a heater of the fuel filter.
Installation is made in the sequence, the return to removal. Before installation grease a sealing ring of a heater with pure fuel (see the drawing).
