I would like to offer some simple preventive maintenance procedures you can follow to not only help prepare your RV for cold temperatures, but to also help prevent untimely breakdowns as a result of the colder weather.
Here are my top 5 RV Cold Weather Maintenance Tips
1) RV Tire Tips: During the warmer months of the year I constantly remind folks not to check tire pressure when the tires are hot, meaning after the RV was driven more than one mile. Hot weather and hot tire temperatures cause tire inflation to increase. But something seldom discussed is what happens to your tire pressure when the mercury plummets? The answer is, when it’s cold outside the air pressure in your tires drops 1 to 2 pounds for every 10 degree drop in temperature. This means if you have not checked the tire pressure in your RV tires since that trip you took last August your tire pressure could be dangerously underinflated when you head out for the holidays. The best advice I can offer is to get in a habit of checking and adjusting tire pressure monthly, so it is correct regardless of the temperature. This applies to your automobiles as well.
2) Automotive Antifreeze Tips: When you talk about RVs and antifreeze most folks think about the RV antifreeze used to protect the RV water system from freezing. We will talk about that type of antifreeze in a minute but first I want to talk about the automotive antifreeze used in the RV or tow vehicle engine coolant system. Glycol antifreeze does several things to help protect your engine:
a. When it’s cold out it helps lower the freezing point of water.
b. The corrosion inhibitors that are added to the antifreeze help prevent scale and rust build-up in the cooling system.
c. It provides protection against boiling during the hot summer months.
d. It helps keep the engine operating at its most efficient temperature regardless of operating conditions and outside temperatures.
Just like engine oil the antifreeze in your RV or tow vehicle automotive cooling system needs to be replaced at regular intervals. If you have not had this service performed in the last few years check your vehicle owner’s manual for the recommended intervals and schedule an appointment to have it done.
