REP-TAT-P-1362-01 Remove the coolant temperature sensor from the crankcase connecting bracket

WARNING: This page is about a different car, the 2018 BMW 340i, 2017 BMW 340i, and 2016 BMW 340i. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Hot surfaces.
Risk of burning!

Perform all work only on components that have cooled down.

NOTE: RISK OF DAMAGE
Electrostatic discharge.
Damage to or destruction of electrical components.

Leave electrical components in original packaging until just before they are installed. Use the original packaging only for any return shipments. Always package removed components straight away.
Read and comply with user information on using the associated special tool 12 7 060.
Only tap the housings of electrical components. Do not tap pins or multi-pin connectors directly.
Wear electrically conductive clothing and antistatic shoes (with ESD symbol).
For additional information see: NOTES ON ESD PROTECTION (ELECTROSTATIC DISCHARGE)

NOTE: TECHNICAL INFORMATION
Immobilization period-long fill of coolant!
Do not 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 emptied and refilled.
In the case of other removal work involving the draining of part quantities of coolant, the coolant level must be topped up with new coolant.

NOTE: TECHNICAL INFORMATION
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.

Unlock and loosen connector (1).
Loosen the coolant temperature sensor (2).
Catch and dispose of leakage coolant.
