8.16 Low-Temperature Circuit

8.16.1 Charge-air coolant – Level check

Preconditions

☑

Engine is stopped and starting disabled.

☑

MTU Fluids and Lubricants Specifications (A001061/..) are available.

WARNING

Coolant is hot and under pressure.
Risk of injury and scalding!
• Let the engine cool down.
• Wear protective clothing, gloves, and goggles / safety mask.

Checking charge-air coolant level at filler neck:

Turn cap on coolant expansion tank counterclockwise to the first stop and allow pressure to escape.

Continue to turn cap counterclockwise and remove.

Note:

Charge-air coolant must be visible at marker
plate.

Check charge-air coolant level.

Top up charge-air coolant as necessary
(→ Page 120).

Check that cap is in serviceable condition.

Clean sealing surfaces as necessary.

Fit cap and close tight.

Checking charge-air coolant level by means of level sensor:

Note:

Coolant level is automatically monitored by engine control system.

Switch on engine control system and check readings on the display.

Top up charge-air coolant as necessary (→ Page 120).
