Motorhome Maintenance

Keeping your motorhome in good shape will help ensure that you enjoy your travels on the road or in the great outdoors. Sitting in a repair shop is never fun, especially when it is in a shop far from home.

Fluids

Here are the regular steps you should take for maintenance of fluids in your motorhome:

Check all fluids at least monthly when the motorhome is sitting and weekly when you are on the road. Top off any fluids that are low.

Change the oil and filter at the intervals the owner's manual advises or even slightly sooner. Use the weight and type of oil the manufacturer advises. Always change the filter at the same time as the oil, as a dirty, blocked oil filter can cause overheating problems.

Check the level of brake fluid without removing the top of the tank. It is rare that you will need to add fluid, but a loss of brake fluid can signal problems.

Check your coolant when the engine is cold and top off as recommended by the manufacturer. This is one fluid you should carry with you, especially if traveling in very warm climates with steep grades. You can also use tap water in an emergency, if your engine boils over before you can get to a service station.

Have the cooling system drained, flushed, and refilled yearly or as recommended by your dealer.

Transmission fluid should be changed yearly in a newer motorhome. Check with an expert at a transmission shop if you have an older RV; it may be better to rebuild the transmission rather than just change the fluids.

Power steering fluid should not have to be changed or added unless there is a leak or a problem with the power steering system.

Change the fuel filter every two or three months. This can help your engine run more effectively and be more fuel-efficient.

Air Intakes

Change the air filters every 2,000 miles, or more often if you are traveling in dusty areas.

Air Conditioning

Check the temperature of the air the air conditioner is blowing out every three to six months. You can get a thermometer at an auto parts store for a few dollars. On max, the reading should be between 45 and 55 degrees. If the temperature is over 55, the air-conditioning units need to be serviced by an auto air-conditioning shop.

Tires

Tires should be checked regularly, including the air pressure. Looks for cracks, embedded nails, evidence of tread separation, or uneven wear. These are all indications that you need to have the tire repaired, replaced, or rebalanced. Check that the lug nuts are tight. Be sure to check your spare tire at the same time.

Brakes

Unless you change the oil yourself, you should have your mechanic check your brakes at the same time you have the oil changed.

Body

Look over the outside of your RV for any signs of leaks or rust. The best thing you can do for the outside of your rig is to keep it clean. If you have traveled in northern areas where they use salt on the roads, or have camped near the ocean, keep your RV rinsed off to prevent rust and corrosion. Be sure to get underneath. You might want to find a truck wash to do a good cleaning.
