RAM 2015 1500, Operating Information Manual, Page: 439 / 998

To check the coolant level:
1. Open the coolant reservoir.
2. Lift and remove the plastic dipstick from the
reservoir neck.
3. Check the coolant level on the dipstick.
The radiator normally remains completely full,
so there is no need to remove the radiator cap
unless checking for engine coolant (antifreeze)
freeze point or replacing engine coolant (anti-
freeze). Advise your service attendant of this.
As long as the engine operating temperature is
satisfactory, the coolant bottle need only be
checked once a month.
When additional engine coolant (antifreeze) is
needed to maintain the proper level, it should be
added to the coolant bottle. Do not overfill.
Checking Coolant Level — 6.4L Engine
The level of the coolant in the pressurized

“MAX” range on the bottle when the engine is
cold.
