Owners FAQ

BX 4TC owners frequently asked questions

Replacement of the waterpump
When you need to replace your 4TC waterpump please check for the waterpump used for the Peugeot 505 Turbo or the Talbot Tagora 2.2l engine. That is almost the same version. This is the same part but with a shortened axle on which is mounted the cast iron pulley of the water pump from the Matra Murena.
Be aware that you need to adjust the setting because there is no space enough between the pump and the radiator. For the rest it will work fine!
Replacement of the clutch
Replacing the clutch is not easy, BX 4TC clutch disk ref : 95 597 359
How many litres of oil inside the gearbox?
The gearbox is the same as inside Citroën SM.  The SM owners always use 3 litres of oil. This way the 5th gear wheel is better lubricated!  Officially it is 2,2 liters. PLEASE NOTE : Do not use GL 5 oil but GL 4 oil. Otherwise the gearbox will be damaged after a while.
Where can I find the technical (after sale) manual of the BX 4TC?
