Then, place the new battery in the vacated spot and connect the terminals to the new battery.

  1. Replacement of Engine Oil

DIY vehicle fixesThis is an easy job that even teenagers can do. You might want to place the front end of your car on a lift or portable stands to access the bottom of the engine compartment.  You’ll need to open the round tap that is present in the lower area of the engine and let the dirty oil run out.  Be sure to have a pan or disposable container ready – the oil drains quickly. After the old oil is removed, replace the round tap to keep the new oil in.  From the top of your engine bay, put a funnel where the oil enters and gradually put in the new oil.  Your owners manual will tell you how much oil to add, and may suggest other DIY vehicle fixes to keep in mind.

  1. Replacement of Air Filter

DIY vehicle fixesAir filters should be changed when the oil is changed.  There are two air filters – one in the engine bay and one within the car to keep bacteria from entering the cabin.  To change the engine bay, you’ll need to locate the pipe that exits the engine and flows to a large box.  If you disconnect the clips and open the box, you’ll find the air filter.

For the cabin, most filter are located inside the glove box behind a panel. You’ll need to remove the clips in order to access it.

  1. Changing Coolant

DIY vehicle fixesCoolant is a green, orange, or clear liquid that keeps the car at a steady temperature.  Without the coolant fluid, your engine overheats and causes more problems that you’d like. To change the coolant, simply detach the plastic bottle that has been placed beside the radiator (you may need to remove plastic pieces to reach the bottle). Filter out the old coolant and put in a fresh liquid.  You may want to run the car for a few minutes before driving, and refer to the owners manual again for any additional DIY vehicle fixes.

Did you know?The function of the fluid is to keep the hot engine and transmission cool when the vehicle is running. Anti-freeze is to keep the fluid from “freezing” in the cold weather

  1. Fuse Replacement

DIY change a fuseA faulty fuse can cause various functionality issues in your car. A fuse is fixed in a slot that’s within a compartment either in your engine bay or under the driver side dash. Some cars provide a pair of tweezers to help you remove a fuse. In most cases, you’ll need a small pair of needle-nose or standard pliers to get the fuse out of the box.

Once the fuse is singled out and removed, you need to determine if it’s blown. This is usually quite easy. For the older glass fuses as well as the new plastic ones like shown here, if the metal link inside the fuse is separated, the fuse is toast. If not, then it’s still good and can be reinstalled.  When replacing a fuse, the most critical element is using the exact same amperage rating as the blown one. If you use a fuse with different amperage rating, you risk either blowing the fuse again, or damaging the equipment the fuse is designed to protect.

Did you know?The idea behind a fuse is that it’s supposed to blow if there’s a surge or short in system’s electrical wiring. For example, if it’s a 10-amp fuse that needs replacing and you replace it with only a 5-amp fuse, the smaller fuse will blow much sooner than it needs to. Conversely, if you replace that 10-amp fuse with a 20-amp unit, it’s possible you’ll damage the part or system before the fuse has a chance to break and save the component

  1. Tire replacement

Woman changing a tireLet’s face it – you’re going to have a flat tire during your lifetime and it will need to be replaced.  Pull over immediately when you have a flat to a safe part of the road.  In your truck will be a jack and tools.  You’ll first need to loosen (NOT remove) the lug nuts using the tire iron also in your trunk.  Place the jack under the car and match the jack’s slot with the frame of your vehicle.  Use the two hand tools to make an “L” connection, then place the hook on the jack and begin rotating your arms.  When the tire has cleared the ground, remove the lug nuts and then the tire.  After that, place the new wheel and tighten the nuts. The last step is to bring the car down from the inclined level and remove the jack.  Don’t forget to tighten your lug nuts!

  1. Changing Wiper Blades

Changing wiper bladesA rusty or worn wiper blade can damage your windscreen. To change them, simply undo the hook (for older models) or slide the rubber blade off (for newer models). Next, insert the new wipers and tighten to secure. Be sure to run the blades before driving to ensure they are attached correctly.

Did you know?You should clean your wiper blades every time you fill your gas tank, and, never use your windshield wipers to de-ice your windshield. Instead, either use an ice scraper or use your defroster to melt snow and ice

  1. Changing your brake pads

Changing brake padsBrake the lugs on your tires, then use a jack to lift your car.  Remove the wheel from your car.  Remove the bolts that are attached to the break caliper so you can slide the brake pads out through the top. Don’t let the caliper hang loosely; secure it using a bungee cord.  Slide the old brake pads out and put the new ones in.  Using a c-clamp, compress the brake piston to the point where it is easy to put the caliper assembly back over the new brake pads.  Replace the bolts once you put the caliper back on. Press your brake pedal a few times to make sure you have good brake pressure.  Put your wheel back on and tighten the lug bolts.

Did you know?Nonasbestos organic brake pads are made from natural materials like glass and rubber, as well as resins that can withstand high heat. In fact, the high heat helps to bind the brake pad materials together. An advantage of organic brake pads is that they’re made of materials that don’t pollute as they wear and they’re easier to dispose of, too.
