There are some conditions in servicing cooling module at Peugeot 807. Otherwise 807 made in 2010 won’t serve you long enough. It’s important to provide cooling for Peugeot’s engine with 2.0 liters volume. It’s better to choose fluid in combination of 2002 year, 2.2 volume of motor and engine code of 3FZ(EW12J4). It’s important to use 11.3 liters of coolant which has Red color.
Use your 2.0 engine longer in 2005 807 by keeping these rules. So better use Peugeot’s advice for servicing 2002 807. A lot of 3FZ (EW12J4) motors are used long in Peugeot cars but only with good service. To endure car life take only Red antifreeze and pour not more or less than 7 liters.
