A diesel pusher motorhome requires a more specialized maintenance approach compared to regular gasoline RVs due to its complex engine and other unique components. Here's a comprehensive maintenance checklist for your diesel pusher motorhome:
The Checklist
Monthly/Before Each Trip:
- Inspect Tires: Check for wear, damage, and ensure they're inflated to the proper psi.
- Check Lights: Ensure all interior and exterior lights are functioning.
- Examine Belts and Hoses: Look for cracks, wear, or any signs of degradation.
- Battery Check: Ensure terminals are clean and that the battery holds a full charge.
- Fluid Levels: Check engine oil, transmission fluid, power steering fluid, brake fluid, coolant, and washer fluid.
- Inspect Brake System: Make sure brakes are responsive and there's no unusual noise.
- Check Wipers and Washers: Replace if worn out.
- Test Emergency Equipment: Including fire extinguishers, smoke detectors, and carbon monoxide detectors.
Quarterly/Every 3,000-5,000 Miles:
- Change Engine Oil and Filter: Diesel engines require specific oil, so make sure you're using the correct type.
- Fuel Filter Replacement: Diesels have primary and secondary fuel filters – both need attention.
- Air Filter Inspection: Replace if dirty.
- Inspect Exhaust System: For leaks or damage.
- Transmission Fluid Check: Look for unusual color or burnt smell.
- Check Cooling System: Make sure the radiator, hoses, and coolant reservoir are all in good shape.
Semi-Annually/Every 6 Months:
- Clean Battery Terminals: Remove any corrosion.
- Lubricate Chassis: Including suspension components and any other moving parts.
- Inspect Drive Belts: Adjust tension if necessary.
- Test Generator: If equipped, run it for at least two hours under 50% load.
- Inspect Roof and Seals: Check for cracks or leaks.
- Slideout Maintenance: Clean and lubricate mechanisms. Check seals.
- Flush Water System: To prevent algae and bacteria build-up.
Annually/Every 12,000-15,000 Miles:
- Transmission Service: Change fluid and filter.
- Coolant System Service: Flush and refill.
- Brake Inspection: Check pads, rotors, and fluid.
- Inspect Air Brakes and Tanks: If equipped, check for moisture in the system.
- Replace Air Dryer Desiccant Cartridge: For air brake systems.
- Differential Fluid Check: Refill or replace if needed.
- Inspect and Lubricate U-Joints.
- Check Radiator and Intercooler: Clean out any debris.
- Inspect and Test Dash Air System.
- Replace Cabin Air Filters.
- Inspect and Clean A/C Units.
- Deep Cycle Battery Service: Check water levels in lead-acid batteries.
Every 2 Years:
- Replace Engine Coolant.
- Replace Hydraulic Fluid and Filters: For leveling jacks and slide-outs, if hydraulic.
- Inspect and Repack Wheel Bearings.
Every 3-5 Years/As Needed:
- Replace Tires: Depending on wear and age.
- Replace Drive Belts and Hoses.
- Inspect and Possibly Replace Brake Lines and Hoses.
- Replace Suspension Components: Such as airbags or shocks if they show signs of wear.
Remember, while this checklist provides a solid guideline, always refer to your diesel pusher motorhome's owner manual for specific recommendations related to your model.
