How to renew the canister of the coolant filter / inhibitor
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 which 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.
Note: There are two types of coolant filter head:
Type 1
1 When the engine has cooled, remove the radiator filler cap to release the system pressure.
Note: When the system pressure is released, valves will close in the filter canister and in the housing for the
canister. This will prevent the loss of coolant when the filter is removed.
2 Thoroughly clean the outside surfaces of the coolant filter assembly.
3 Use a strap wrench or similar tool to loosen the filter canister and remove the canister. Valves in the filter
head will prevent the loss of coolant when the canister is removed.
4 Ensure that the threaded adaptor (A2) is secure in the filter head and that the inside of the head is clean.
5 Lubricate lightly the seal (A1) on top of the new canister with clean engine coolant. Fit the new canister to
the filter head and tighten, by hand only. Do not overtighten the canister.
Type 2
1 When the engine has cooled, remove the radiator filler cap to release the system pressure.
2 Turn the lever (B1) fully counter-clockwise, to the close the valve. This will prevent the loss of coolant when
the canister (B3) is removed.
3 Thoroughly clean the outside surfaces of the coolant filter assembly.
4 Use a strap wrench or similar tool to loosen the filter canister and remove the canister.
5 Lubricate lightly the seal on top of the new canister with clean engine coolant. Fit the new canister to the
filter head and tighten until the seal touches the filter head, tighten a further one rotation by hand only. Do not
overtighten the canister.
6 Turn the lever (B2) fully clockwise, to the open the valve. This will allow the flow of coolant through the
canister.
