Step-by-Step Guide
Step 1: Oil Change
The oil change is a crucial maintenance task that should be performed every 5,000 to 7,500 miles. To start, locate the oil drain plug underneath the car and use a 10mm socket to loosen it. Once loose, use a drain pan to catch the old oil as it drains out.
Sub-Step 1.1: Locate the Oil Filter
The oil filter is located on top of the engine and can be removed using an oil filter wrench.
Sub-Step 1.2: Install the New Oil Filter
Once the old oil filter is removed, install a new one by hand tightening it in a clockwise direction.
Step 2: Spark Plug Replacement
Spark plug replacement is another essential maintenance task that should be performed every 30,000 to 100,000 miles. To start, locate the spark plug wires and use a spark plug socket to remove the old spark plugs.
Sub-Step 2.1: Remove the Spark Plug Wires
Use a spark plug wire puller to remove the spark plug wires from the spark plugs.
Sub-Step 2.2: Install the New Spark Plugs
Once the old spark plugs are removed, install new ones by hand tightening them in a clockwise direction.
Step 3: Brake Pad Replacement
Brake pad replacement is a more complex maintenance task that should be performed every 30,000 to 50,000 miles. To start, locate the brake calipers and use a 12mm socket to loosen the caliper bolts.
Sub-Step 3.1: Remove the Caliper
Once the caliper bolts are loose, use a pry bar to remove the caliper from the rotor.
Sub-Step 3.2: Install the New Brake Pads
Once the old brake pads are removed, install new ones by sliding them into place and securing them with the caliper bolts.
Pro Tips & Common Mistakes
