If you are going a road trip, these four fluid levels should be checked prior to getting on the road.
Engine Oil
If your car's engine oil is low, it needs to be replaced or changed altogether. Lacking engine oil can cause serious mechanical problems that will be expensive to repair.
Coolant
Engines get very hot while in motion; however, coolant will prevent them from overheating.
Transmission Fluid
Transmission fluid is a multipurpose liquid whose main objective is to lubricate parts of the transmission. However, it also aids with cooling, conditioning and cleaning.
