Checking the Coolant Level (Hot Check)
Checking the Coolant
Level (Hot Check) - Ops
Check the coolant levels as follows:
- Allow the engine to run for approximately five minutes at a moderate speed.
- After the coolant temperature reaches 50°C (122°F), recheck the coolant level in the surge tank.
- Add more coolant if necessary. Open the heater valves before adding coolant.
- Do not close the heater valves until the engine has been running briefly and the coolant level is again checked and corrected as necessary.
Warning: HOT COOLANT
To avoid scalding from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Wear adequate protective clothing (face shield, rubber gloves, apron, and boots). Remove the cap slowly to relieve pressure.
