You should be careful at choosing liquids for Citroen especially for vehicles having 1.1 motor. Before choosing fluid note that engine code 109/5E and volume of 1.1 were installed to your car in 1984. For 1985 LNA engine it’s necessary to get normal temperature balance. Only exact type of antifreeze will suit Citroen LNA cooling system. For filling up the system you will use 6.5 liters of special Green coolant type.
Produced in 1984 the 1.1 engine in LNA model will serve longer by this. It’s obvious that every 109/5E motor needs good service as stated by Citroen in instruction. So better use Citroen’s advice for servicing 1985 LNA. So, don’t choose different from Green coolant and obey the number of 6.5 liters.
