OPERATING AND MAINTENANCE-C.4 6. Drain the cooling system, see below. To give protection against corrosion, it is better to fill the cooling system with a coolant that has a corrosion inhibitor, see 'Engine Coolant' below. If frost protection is needed, use an antifreeze mixture. If no frost protection is needed, use water with an approved corrosion inhibitor mixture. 7. Run the engine for a short period to send the lubricating oil and coolant around the engine. 8. Clean out the engine breather pipe and seal the end of the pipe. 9. Remove the atomisers and spray POWERPART Lay-Up 2 into each cylinder bore.
If this is not available, clean engine lubricating oil will give a degree of protection. Spray into the cylinder bores 140 ml L1- pint) of lubricating oil divided evenly between the four cylinders. 10. Slowly turn the crankshaft one revolution and then install the atomisers complete with new seat washers. 11. Remove the air filter and any pipe installed between the air filter and induction manifold. Spray POWERPART Lay-Up 2 into the induction manioold. Seal the manifold with waterproof tape. 12. Remove the exhaust pipe. Spray POWERPART Lay-Up 2 into the exhaust manifold. Seal the manifold with waterproof tape. 13. Remove the lubricating oil filler cap.
Spray POWERPART Lay-Up 2 around tne rocker shaft assembly. Fit the filler cap. Where the oil filler cap is not on the cylinder head cover, remove the cover to spray the rocker shaft assembly. 14. Disconnect the battery and put it into safe storage in a fully charged condition. Before the battery is put into storage, give the battery terminals a pro- tection against corrosion. POWERPART Lay-Up 3 can be used on the terminals. 15. Seal the vent pipe of the fuel tank or the fuel filler cap with waterproof tape. 16. Remove the fan belt and put it into storage. 17. To prevent corrosion, spray the engine with POWERPART Lay-Up 3. Do not spray inside the alternator cooling fan area.
it must have an ethanediol (ethylene glycol) base with a corrosion inhibitor. It is recommended that the corrosion inhibitor is of the sodium nitrate/benzoate type. The antifreeze mixture must provide cooling/corrosion protection at least as good as the requirements of the standards below: UK: 8S.6580: 1985: "Specification for corrosion inhibiting, engine coolant concentrate (antifreeze)". U.S.A. ASTM 03306-74 'Ethylene Glycol Base Engine Coolant'. Australia AS 2108-1977 'Antifreeze Compounds and Corrosion Inhibitors for Engine Cooling Systems'. When Perkins POWER PART antifreeze is used, the correct mixtures of antifreeze and water are as given below.
Perkins POWERPART Antifreeze fully passes the above standards. Lowest Temperature of Protection Needed %Volume of POWERPART Antilreeze Mixture Ratio by Volume POWERPART Antifreeze:Water -12°C ( 10°F) -18°C ( O°F) 25°C ( 13°F) -37°C (-34°F) 25 33 40 50 1:3 1:2 1:1.5 1 :1 The quality of the antifreeze coolant must be checked at least once a year, for example, at the start of the cold period. 3. When frost protection is not necessary, it is still an advantage to use an approved antifreeze mixture as this gives a protection against corrosion and also raises the boiling point of the coolant.
A minimum concentration of 25% by volume of antifreeze is necessary, but it is our recommendation that 33% concentration by volume is used. If an antifreeze is not used, add a correct corrosion inhibitor mixture to the water. Change the water/corrosion inhibitor mixture every six months or check according to the inhibitors manufacturer's recommendations. Note: Some corrosion inhibitor mixtures contain soluble oil which can have an adverse effect on some types of water hose. If the correct procedures are not used, Perkins Engines Ltd., can not be held responsible for any frost or corrosion damage. NOTE:
Before the engine is started after a period in storage, operate the starter motor with the engine stop control in the 'off' position until oil pressure shows on the oil pressure gauge or the oil warning light goes out. If a solenoid stop control is used, this will have to be disconnected for this operation. If the engine protection is done correctly accoding to the above recommendations, no corrosion damage will normally occur. Perkins Engines Ltd. are not responsible for any damage that occurs in relation to a service storage period. To Drain the Cooling System 1. Ensure that the vehicle or machine is on level ground. 2. Remove the radiator filler cap. 3.
Remove the drain plug from the side of the cylinder block (see engine views) to drain the engine. Ensure that the drain hole does not have any restriction. 4. Open the tap or remove the drain plug at the bottom to drain the radiator. If a tap or plug is not fitted to the radiator, disconnect the bottom radiator hose. 5. Where necessary, flush the system with clean water. 6. Fit the drain plugs and radiator cap. Where necessary, close the radiator tap or connect the radiator hose. Engine Coolant 1 he quality of the coolant used can have a large effect on the efficiency and life of the cooling system.
The recommendations given below can be of assistance in the maintenance of a good cooling system with frost and/or corrosion protection. 1. Where possible, use clean soft water. I 2. If an antifreeze mixture, other than Perkins POWERPART, is used to prevent frost damage,
