Chrysler 300M, LH (USA / CAN)

Coolant capacity & service interval

Chrysler 300M, LH (USA / CAN) coolant capacity ranges from 7,8 to 8,9 liters. Service intervals include checking every 1 months, changing every 160000 km or 60 months, and changing every 102000 miles or 60 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Chrysler 300M 3.5 cooling system holds 7.8 liters in the Canadian configuration, while the USA configuration lists a capacity range of 7.8 to 8.9 liters, indicating a variable fill volume depending on the specific service or drain condition encountered during the procedure.
  • The 0.9-liter spread in the USA capacity figure suggests the lower value represents a partial drain refill and the upper value reflects a more complete system evacuation, such as when the block is fully drained alongside the radiator.
  • The Canadian specification carries a normal use condition tied to a 160,000 km or 60-month change interval, meaning the interval applies to standard operating conditions rather than elevated stress or short-trip driving patterns.
  • The USA specification is assigned an initial service use condition, which means the 102,000-mile or 60-month interval applies specifically to the first coolant change rather than to subsequent recurring service events.
  • Both the Canadian and USA configurations share the same 60-month time limit, meaning five years serves as the maximum service life of the coolant regardless of whether the distance threshold has been reached first.
  • The Canadian specification includes a monthly check interval, meaning the coolant level and condition are to be inspected every month as a routine maintenance step separate from the full change interval.
  • The 102,000-mile distance threshold in the USA specification corresponds to a long-life coolant formulation, as conventional coolants typically carry shorter mileage limits well below that figure.
