Traveling with Your Car
The following tips are from the Better Business Bureau.
Preparing your car for travel is very important. Make sure your car is ready for the trip by checking all vital fluids such as the oil and coolant, and by visually inspecting your car for anything that looks out of place. It is always a good idea to double-check the coolant hoses and all belts on your car. Failures of these items are among the most common reasons that cars break down; but fortunately, they are inexpensive to replace.
