WARNING: This page is about a different car, the 2010 BMW 135i, 2009 BMW 135i, and 2008 BMW 135i. However, it is still accessible from the selected car via links, so may be relevant.

Special tools required:

00 2 030

See MAINTENANCE AND GENERAL INFORMATION - SPECIAL TOOLS .

WARNING: Danger of scalding!
These tasks on the cooling system should only be carried out on an engine that has cooled down!

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 partial quantities of coolant, replace these quantities which have been drained with new coolant.

Installation:

Use only recommended coolant. See COOLING SYSTEM - OPERATING FLUIDS .

Observe mixture ratio .

Protective measures/rules of conduct:

Wear protective goggles
Wear protective gloves
Observe national/country-specific regulations

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

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

Recycling:

Observe country-specific waste-disposal regulations.
