Gasoline engine Diesel engine
Only ethylene glycol based coolant with a
corrosion inhibitor suited to aluminium alloy engine components should be used in thecooling system. No further additives or inhibi- tors should be used. The coolant specific gravity should be checked as prescribed inthe maintenance schedule to ensure adequatefrost and corrosion protection. In addition, theengine coolant must be replaced at the speci-fied interval since the corrosion inhibitor prop-erties deteriorate with time.
It is important to note that whilst an increase
in the concentration of anti freeze gives anincrease in the level of frost protection, asolution which is in excess of 65% anti freezewill result in reduced frost protection andengine overheating. Therefore the recom-mended concentration of 50% should not beexceeded for general use.
The use of methanol based anti freeze com-
pounds may result in engine overheating andwill invalidate the vehicle warranty.
4. When the oil has drained from the sump,
replace the drain plug using a new washerensuring that the plug is not over tight-ened.
5. Remove the oil filter by rotating counter- clockwise, using a proprietary oil filter re-moval tool if necessary. Note that the oilfilter will contain approximately 0.5 litres ofoil and this should be collected in a suit-able receptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotatingclockwise until the filter contacts the mount-ing and then a further one half turn. Do notover-tighten Tightening torque: 2.3 ~ 2.5 kgf.m
7. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure thatno oil leaks exist. Turn off the engine andafter a couple minutes, recheck the oillevel.
WARNING:Prolonged and repeated contact with used
engine oils may result in serious skin dis-orders including dermatitis and cancer.Avoid contact with skin as far as possibleand always wash thoroughly after any con-tact. Keep used oils out of reach of chil-dren. It is illegal to pollute drains, watercourses and soil. Use only authorized wastecollection facilities including civic amenity sites and garages for the disposal of usedoil and oil filters. If in doubt, contact thelocal authority for disposal instructions.
