10 tips to maintain a diesel engine RV

Regular maintenance is absolutely imperative if you want your diesel recreational vehicle (RV) to serve you for some good number of years. Diesel engines require no ignition tune ups or major repair to last longer; they only entail regular low cost-preventive maintenance that can pay big dividends in the long run. Here are 10 maintenance tips that will help to keep your diesel engine motor home at top-notch condition.

1. Replace the air, fuel, coolant and hydraulic filters in your RV

To maintain the health of your RV’s engine, you need to change the air, fuel, coolant and hydraulic filters of your vehicle on a regular basis. Changing the same is recommended by the manufacturer in order to prevent condensation from building up and getting into the fuel injectors. The fuel tank should always be kept full to avoid moisture formation.

2. Warm the engine up, slowly

Turbo diesel vehicles can surprise you with its performance, but it is better not to start your motor home too fast. You are not out here to compete in a car race. If you want your motor home to serve you well for years without any major complaint, you should give some time to the engine to warm up slowly. After igniting the engine, drive slowly on medium speed for a few minutes, and don’t rush or apply the brake too frequently.

3. Check the glow plugs regularly

Regular inspection of glow plugs is very important to ensure proper maintenance of a diesel engine motor home. The ignition of this engine depends upon compressed heat but it often fails to produce enough heat for the fuel to burn. As a result, the glow plugs are used to heat up the cylinder before the cold engine gets ignited and therefore, these glow plugs require frequent inspection especially during the winters.

4. Replace the oil filter

While a gasoline engine RV gives less mileage or performance with a dirty fuel filter, this can be more serious in the case of a diesel engine, where this dirty fuel can entirely damage an engine’s fuel injection system. The oil filter should meet or exceed the standards suggested by the manufacturer so that Sulphur and Carbon residues can easily be removed. Manufacturers suggest using synthetic oil for diesel engines.

5. Avoid short distances

Driving on a cold engine, especially at low speed is very unhealthy for diesel RVs as these are equipped with particulate filters and this can be subjected to clogging. It is also worth remembering that the filter replacement is associated with high cost.


6. Check the warning system of the engine

The early signs of an engine overheating should be attended to immediately. A gasoline engine if overheated can be shut off, cooled down and restarted. However, if a diesel engine gets overheated, it will get damaged and has to be replaced.

7. Control the temperature

While driving a diesel engine motor home, pay attention to the temperature of the engine and keep it at around 90 degrees. It is an optimal temperature which indicates that the engine has already warmed up.

8. Drain the water separators

Most diesel engine RVs have water separators that collect water from fuel. This water needs to be drained out regularly from the separator using a drain valve called petcock.

9. Check the gaskets of your vehicle

Gaskets should be checked and replaced on all critical areas especially in the combustion mounting areas to avoid further complications.

10. Install an engine heating kit

Installing an engine heating kit for diesel engines play an important role especially in winter when diesel powered vehicles take much time to start. This kit saves fuel and prolongs the life of a diesel engine while cutting down on exhaust emission.

By following these 10 tips, your Diesel RV will serve you well for many years. It is also worth devoting a bit of attention to your vehicle if you want to have only good memories from your journeys.
