Engine Coolant Reservoir:
A “see-through” plastic reservoir, similar to the familiar windshield wash-
er jar, is connected to the radiator by a hose. As the motorhome is driven
coolant is heated and expands. A portion of fluid displaced by this expansion
flows from the radiator into the reservoir tank. When the engine is stopped,
and coolant cools and contracts, displaced coolant is drawn back in the radia-
tor by a vacuum. Thus, the radiator is kept filled with coolant to the desired
level at all times resulting in increased cooling efficiency. The coolant level
should be at or above the appropriate mark on the reservoir tank when the
system is cold.
• Check the coolant level daily or when refueling.
• Drain and flush the coolant system every 60,000 miles or two years, and
refill with a heavy-duty coolant (50/50 mix of water and anti-freeze).
• If the coolant is below the MIN mark, the low coolant alarm will sound
and the low coolant light will appear on the dash. You will need to stop
and check for coolant loss before driving.
• The coolant level is to remain between the MAX and MIN level in the
reservoir.
Routine Maintenance Recommendations:
1. Check the SCA concentration level every 15,000 miles/6 months.
2. Change the coolant filter every 15,000 miles/6 months.
3. Drain and flush the system every 240,000 miles/2 years, and refill with
a heavy-duty coolant (50/50 mix of water and antifreeze).
4. Always use antifreeze. In addition to freeze protection, antifreeze is
essential for overheat and corrosion protection.
5. The supplemental coolant additive (SCA) is required.
6. Freeze point should be measured every 15,000 mile/6 months.
