Disconnect the negative pole from the battery before starting work.
NB:
Before disconnecting the battery, make sure that the owner knows the code for the car radio.
Do not use the wedge pins to block the engine when unscrewing or tightening the crankshaft pulley.
Never use the belt as a holding tool to block or remove the camshaft pinion nuts.
Never exert pressure to force on the pulleys and rollers at the point where the distribution belt arrives in position.
Do not fold the belt or turn it inside out or bend it less than a 25mm radius.
Do not use lever or force to put a belt in place.
Check the belt idlers, stationary rollers and water pump through rotation.
Check the alignment of pulleys and rollers.
Check there is no oil leak or seepage. If so, remedy the problem.
When replacing the distribution belt, check that the new belt is fi tted with the right kind of tooth.
Comply with the belt tension
Comply with the tightening torques.
Comply with the rotation direction indicated by the arrows on the distribution belt
Never re-install a worn distribution belt, but replace it.
Never re-stretch a distribution belt, but replace it.
Replace the belt if it shows signs of wear and tear - friction, cracking, damaged, cut, eroded or worn teeth, worn wall, worn edges or clogged with oil.
Any damage caused to the belt must be thoroughly investigated so as to defi ne the causes before re-assembling a new belt.
Never use solvents (Diluent, petrol, etc.) to clean the oil deposits on the surface of the belt. In case of doubt replace the belt.
Any cleaning must be carried out with care using a soft, dry brush.
Never turn the belt inside out to clean it or for inspection.
Always run the engine in the normal rotation direction, failing contrary instructions from the maker of the vehicle.

ALFA ROMEO and FIAT 1.9JTD/2.4JTD engines require the following timing tools from DT.FIAT-D
DT.4776 Camshaft Setting Tools (Pair)
DT.4543 Crankshaft Locking Tool
DT.4528 Flywheel Holding Tool (crank pulley removal)
Alfa Romeo/Fiat 1.9JTD diesel variants can be single camshaft 8valve or twin camshaft 16 valve engines.
2.4JTD diesels are 5 cylinder and can be single camshaft 10valve and twin camshaft 20valve. All these engines are common rail diesels – BELT DRIVE.
The timing belt confi guration is the same for all engines with the belt from crankshaft driving the camshaft and high pressure pump. On the twin camshaft
engines the belt drives only the exhaust camshaft which in turn drives the inlet camshaft, via gears.
DT.4543 Crankshaft Locking Tool is required for all variants, to 'lock' crankshaft position.
On the single camshaft engines the camshaft is aligned by timing marks, but on twin camshaft engines DT.4776 Cam Setting Tools are required to 'lock' the
camshafts in timed position.
NOTE: As it will be necessary to remove the engine mounting/brackets to remove and fi t the timing belt, the engine must be supported from below.
