Coolant Level
Check
WARNING
Do not remove the radiator cap from a hot
engine. Wait until the temperature is below
50C [120F] before removing the pressure
cap. Failure to do so can result in personal
injury from heated coolant spray or steam.
Remove the filler cap slowly to relieve
coolant system pressure.
NOTE
Never use a sealing additive to stop leaks in
the coolant system. This can result in coolant
system plugging and inadequate coolant flow
causing the engine to over-heat.
The coolant level must be checked daily, refer to
TM 5-3810-307-10 for correct procedures for
checking coolant level.
