MAINTENANCE
EXTERNALLY CHECK INTERCOOLER FOR
OBSTRUCTION - Tdi
Clear any trapped dirt or flies from vanes of
intercooler
CLEAN INTERCOOLER ELEMENT - Tdi
Remove
1.Remove intercooler element.
2.Flush intercooler with ICI 'GENKLENE'or
à oD-SOLVE' propriety cleaner, following the
manufacturer's instructions.
3.Dry the intercooler completely ensuring that no
liquid remains in the element.
Refit
4.Refit intercooler element.UNDER VEHICLE MAINTENANCE
Vehicles operating under severe conditions of dust,
sand, mud and water should have oils changed and
lubrication carried out at more frequent intervals than
is recommended in maintenance schedules.
RENEW ENGINE OIL AND FILTER - Tdi
CAUTION: Serious damage to the
turbocharger will result if engine is run
above idling speed before oil pressure is
restored.
RENEW ENGINE OIL - V8i
RENEW ENGINE OIL AND FILTER - V8i
CAUTION: To prevent an airlock occuring
after removing filter, fill new filter with oil
and fit immediately after removing old
filter. If airlock does occur fill oil pump with
petroleum jelly.
