17 00 039 Venting and filling cooling system with vacuum filling unit: Notes

WARNING: This page is about a different car, the 2011 BMW 750xi, 2011 BMW 750Lxi, 2010 BMW 750xi, and 2010 BMW 750Lxi. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required 

IMPORTANT: Lifetime coolant filling: 

Never reuse used coolant!

When replacing and removing components which rely on the corrosion protection effect of the coolant, it is essential to change the coolant. The cooling system must therefore be drained and refilled.


In the case of other removal work involving the draining of part quantities of coolant, replace these quantities which have been drained with new coolant.
IMPORTANT: You must protect the alternator against contamination by coolant when carrying out repair work on the cooling circuit.

Cover alternator with suitable materials.


Failure to comply with this procedure may result in an alternator malfunction.

Note on ordering:

IMPORTANT: Risk of slipping due to coolant on the floor.
Danger of injury! 

Catch and dispose of emerging coolant in drip tray (1) and if necessary special tool 00 2 030 (universal hydraulic lifting equipment).

Recycling: 

Observe country-specific waste disposal regulations.
