Citroen C4 - Video tutorial

Model: Citroen C4 MK 1 - Years 2004-2010
Part: Engine
Operation: Valve guide rubbers replacement

When replacing the cylinder head gasket or carrying out a repair which in any case involves the latter, it is a good idea to replace the valve guide rubbers as well. It is therefore necessary to use the special arc clamp to squeeze the valve return spring, separate the fixing shells and extract the valve itself from its seat; then remove the old rubber and insert the new one after lubricating it; also lubricate the valve before inserting it in its seat and reassemble the spring taking care to accurately position the fixing shells. Repeat the same steps for all valves.

How to reset the Renault Master AdBlue warning light

If when you turn on the ignition you see a strange warning relating to AdBlue, do not worry because it is nothing serious. Everything is solved in a few minutes and with a very low cost. In fact, it is a particular additive used in Diesel engines to reduce the environmental impact. Before continuing with the various steps it is therefore necessary to purchase a tank of AdBlue. Furthermore, all the various operations must be carried out with the engine off. The AdBlue tank is located on the passenger side, between the door and the tailgate. Unscrew the blue cap present and pour in the new AdBlue with the help of a rubber hose or an appropriate funnel. Once this is done, you can close the tank and the flap. Switch on the ignition again and the warning light has disappeared.
