Routine Inspection and Upkeep

Here, we’ll focus on the essential monthly checks and tire maintenance you should perform to keep your car running smoothly.

1. Monthly Checks: Oil, Coolant Levels, and Air Filters

1. Check the Oil Level: It’s essential to check the car’s oil level monthly to ensure the engine is well-lubricated and running smoothly. To check the oil, park on a level surface, turn off the engine, and wait a few minutes for the oil to settle. Use the dipstick to check the level. If the oil level is low, top it up with more oil as required.
2. Inspect Coolant Levels: Overheating can cause significant engine damage. Check the reservoir’s coolant level to ensure it’s between the “min” and “max” marks. Never open the radiator cap when the engine is hot; it can lead to severe burns.
3. Examine the Air Filter: A clean air filter improves engine efficiency and performance. Take out the air filter and hold it against a source of light. If you can’t see the light coming through, it’s time to replace it. Generally, this should be done every 12,000 to 15,000 miles, but a monthly inspection will catch any premature clogging.

2. Tire Maintenance: Pressure, Tread Depth, and Seasonal Changes

1. Check Tire Pressure: Check the tire pressure monthly, including the spare. Refer to your vehicle’s manual for the recommended pressure, and use a reliable tire gauge. Adjust the pressure when the tires are cold for an accurate reading.
2. Inspect Tread Depth: Tires with insufficient tread cannot grip the road properly, especially in adverse weather conditions. Use a tread depth gauge or the penny test (insert a penny into the tread with Lincoln’s head upside down; if you can see the top of Lincoln’s head, it’s time for new tires). The minimum legal tread depth requirement is 2/32 of an inch.
3. Prepare for Seasonal Changes: If you live in an area with severe winter conditions, consider switching to winter tires for enhanced traction. Conversely, when warmer weather returns, switching back to all-season or summer tires will provide better performance and may help conserve fuel.
