C5 X7 3.0 V6 240 HDI Coolant amount?

Post by marsalek »

Dear colleagues,

what is the amount of coolant in C5 X7 3.0 V6 240 HDI?

I found out I can use Glysantin G30. Any objections or suggestions on that?

How / where do I de-air the system? As usually on the thermostat housing and at the inlet to the passenger cabin / heater matrix?


Thanks a lot for all tips!
Regards, Karel

Hi colleagues,
does anyone know how much coolant exactly is there in the DT20C engine? I could only drain about 6 liters from the cooler hose. Then I flushed the system several times with water. I found only the air bleeding screw close to the heater matrix. Is there any other possibility to bleed air?

Thanks a lot
Karel

Karel, there's no specific volume in the service info. The system can be filled by 2 methods - gravity and vacuum. When filling by gravity, it must be filled until the flow comes out of the bleed screw with no bubbles. With the Vacuum method, the quantity drained must be measured + 20%. I suspect this is deliberate as it could be easy to overfill and cause major problems.

Both methods are detailed here, with the degassing procedure:

Hi Marc,
thank you very much! I filled pure water by the "gravity method" with a bottle upside down, but I will give it a try with the vacuum method when I fill the proper antifreeze in the next days.
