Servicing the engine
The VOLVO warranty for exchange engines (factory
new or overhauled) applies on the following condi-
tions:
1.
Fuel filters, oil filters
Both the engine’s fuel filters and both the oil filters
must be changed at the same time.
2.
Cooling system
It must be possible to make use of the cooling sys-
tem’s entire capacity. The radiator must be well-
cleaned both inside and outside, or new. Change
coolant filters, if such are fitted.
3.
Hoses
Use new hoses for both the cooling and heating
systems and new hoses for the oil pipes.
4.
Drive belts
Use new drive belts for the fan prop shaft, altern-
ator drive, etc.
Replacing fuel filters
Special tool:
(999) 6670 Filter removal tool
The fuel gauge pressure decides when the filter should
be changed, see also under “Service and maintenance”.
Replace both filters at the same time.
1.
Clean the outside of the filter bracket to prevent
dirt getting in when fitting the new filter.
2.
Unscrew and discard the filters. Use tool 6670 if
the filters cannot be unscrewed by hand.
3.
Screw on the new fuel filters. First by hand to
when the seal makes contact with the filter bracket
and then manually tighten a half turn more.
4.
If there is a relief valve mounted on the injection
pump then normally there is no need to bleed the
fuel system. Instead manually pump about 15
strokes with the hand primer and then start the en-
gine.

5.
Air cleaner
Thoroughly clean the air cleaner housing and con-
nections. Install a new filter and check the filter
housing and hose connections for leakage.
6.
Instruments and connections
Make sure oil pressure and coolant pressure
gauges show correct pressures.
Other measures
Components such as the alternator, starter motor, air
compressor and steering servo pump must not be faulty
and preferably recently inspected.
