Tips for Cold Weather from MCI

“Inspections are an integral part of a preventative maintenance program to ensure your coaches run smoothly in every season,” says William Pfeifer, Technical Solutions Manager, MCI.

Follow MCI’s maintenance “to-do” list to keep things running smoothly when the weather is not.

Keep coolant mixture strength and P.H. levels as specified by the coolant manufacturer.
• Pressurize the engine cooling system and check for leaks. Cooling systems may develop “cold water leaks” at lower temperatures.
• Check the main blower, defroster motors, brushes, and amperage draws.
• Unclog heater cores if needed and clean or replace air filters.
• Clean battery posts and check water levels for the proper State of Charge.
• Verify that all electrical cable connections are tight and corrosion free. Apply protective coating to prevent corrosion.
• Inspect engine and lavatory holding tank immersion heaters and connections.
• Make sure the windshield washer solvent is at the right concentration level to prevent freezing.
• Turn on the windshield wipers to ensure the motor and washer are operating properly, and look for cracking rubber on the wiper blades to determine if replacements are needed.
• Replace cracked or chipped windshields.
• Install valve stem caps on all tires and keep tire pressure at recommended levels.
• Refer to auxiliary heater maintenance manuals for pre-winter preparation instructions.
• Inspect the spare tire and fire extinguisher and keep a belt and bulb kit on board.
