Coolant filter
To renew the canister of the coolant filter / inhibitor
Operation 12-1
Warning! Do not remove the canister while the engine is still hot and under pressure because dangerous hot
fluid can be discharged.
Caution: The canister contains a corrosion inhibitor that is circulated around the cooling system as the coolant
passes through the canister. It is important that only the genuine correct Perkins canister is used.
1 When the engine has cooled, remove the radiator filler cap to release the system pressure.
Notes:
l
Up to engine number N117199, when the system pressure is released, automatic check valves in the filter
head will close to prevent the loss of coolant when the filter canister is removed.
l
From engine number N117199, a manual valve is fitted and is shown open (A2). When the system pressure
is released, the valve lever must be turned counter-clockwise to the closed position (A1) to prevent the loss
of coolant when the filter canister is removed.
2 Thoroughly clean the outside surfaces of the coolant filter canister.
3 Use a strap wrench or similar tool to loosen the filter canister and remove the canister.
4 Ensure that the threaded adaptor (B2) is secure in the filter head and that the inside of the head is clean.
5 Lubricate lightly the seal (B1) on top of the new filter canister with clean engine coolant. Fit the new canister
to the filter head and tighten by hand. Do not overtighten the canister.
6 Turn the lever (A2) 90° clockwise to open the valve. This will allow the flow of coolant through the canister.
