5 Easy DIY Car Repairs

We all know that regular servicing and basic car maintenance are crucial to avoid unexpected breakdowns and expensive repairs. While you should always take your vehicle to a professional mechanic for servicing and major jobs, there are some basic repairs and maintenance you might be able to fix yourself. So as long as you’ve got some basic knowledge and all the right tools, these are 5 easy DIY car repairs that can typically be done at home in 30 minutes or less.

Swap Windshield Wipers

The rubber blades on your windshield wipers will regularly need to be replaced as they wear out over time. The good news is that replacing your old blades with a new set is one of the easiest DIY repairs. Just make sure you get the correct length and type of blades for your vehicle by checking the in-store reference manual or electronic device.

Some require different size blades, and others have rear wipers as well. Remove the old blades via the sliding clasp or button mechanism and follow the instructions provided on your replacement wipers to install them.

Exchange Battery

Car batteries always seem to die at the worst possible moment. All you need is a basic set of wrenches and the replacement process for a dead battery will be a pretty easy job. Once you’ve removed any battery covers, it’s important to disconnect the black or blue negative cable first and disconnect the red positive cable. Always make sure the cable clamps aren’t touching the battery posts or any other metal. Then simply remove the battery by undoing any securing screws or clamps, dropping in the new one, securing it in place, and reattaching both cables in the reverse order – positive first and then negative.

Replace Spark Plugs

Like the battery, spark plugs are pretty important because your car won’t work without them. While they should last for around 100,000 miles, spark plugs may need occasional cleaning and will eventually need to be replaced. The difficulty to remove spark plugs is typically pretty easy, but this will ultimately depend on your specific vehicle. All you should need is a specialized spark plug wrench, the correct replacement plugs, and possibly a torch or a mirror to help see where each one is located. Follow one of the cables back to a cylinder, unplug it, replace the spark plug using the specialized wrench, and then plug the cable back in. Repeat this for each of your 4, 6, or 8 cylinders.

Change Light Bulbs

As most state driving laws require headlights and taillights to be working at all times, you should be checking they work once every few months. If any lights aren’t working and the fuses are okay, all you’ll need is a wrench or a screwdriver to change the bulb yourself. It should be pretty easy to open up the back housing of your light to remove the broken bulb. Then to ensure you purchase the right replacement, check the bulb specs in your manual or look up the year, make, and model of your vehicle at the auto store. Then simply install the new bulb, replace the cover, and test it.

Flush Radiator

As your radiator is responsible for keeping the engine temperature down, it always needs to be working correctly. That means regularly replacing the coolant and flushing out the radiator to avoid buildup. Because when coolant wears out, you could end up replacing the radiator, water pump, heater core, or even the whole engine! Once you’ve removed the drain plug at the bottom of the radiator with a wrench or a screwdriver, use some specialized radiator cleaning product with a garden hose to flush it out. Use special sealant liquid to stop any leaks in the radiator, and you can use special tape to plug up any leaky hoses.
