7.9 Coolant Circuit, General, High-Temperature Circuit

7.9.1 Engine 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 engine coolant level

Read off fuel-optimized (→ Page 27) or emissions-optimized (→ Page 31) system filling pressure at pressure
gage.

Top up with treated coolant as necessary (→ Page 175).
