SPECIAL TOOLING REQUIRED
Mot. 1265 Pliers for removing quick release
unions
LOCATION
The fuel filter is located under the vehicle in front
of the fuel tank.
99214R
REPLACEMENT
Replace the fuel filter at each major service.
REMOVAL
Before removing the filter, take precautions to
catch the fuel which will run out (do not clamp
the pipes as they will be damaged).
Remove the clips (1).
Disconnect the pipes with quick release unions (2)
using tool Mot. 1265.
Remove bolt (3) and remove the fuel filter.
REFITTING
Observe the direction of fuel flow (marked by an
arrow on the filter).
Reconnect the pipes by hand (it is not necessary to
use tool Mot. 1265).
Ensure the quick release unions are correctly
connected.
Refit the safety clips (1).

LOCATION
Principle of the electric heater
The heater has heated studs. They are ceramic,
made from barium titanate which has a positive
temperature coefficient, meaning that its
resistance increases as its temperature increases.
