DIY Car Repair

Car repair can be scary but sometimes you just don’t need a mechanic.

In the past we've discussed how long it takes to repair a car and how major car repairs should always be handled by a professional for the sake of your car’s health. However, there are a selection of simple fixes that people are bleeding money on by sending them into the garage, rather than getting down and dirty with the work themselves.

And that’s what it’s all about! Yes, of course, there’s a financial benefit to performing some simple home repairs- you’ll save money. Lovely. However, that’s not what this is about here. It’s about the satisfaction you will get personally from knowing that your prized ride is thriving because of the TLC by your own hand.

A simple B&Q tool kit is all you’ll need to perform these repairs, in addition to the replacement parts themselves. With links to guides, the tools you'll need and a few due safety concerns, it’s time to get hands on with your car and our guide towards how you can best repair it yourself today.

1. The Car’s Battery

With a bit of care, changing your car’s battery can be a far simpler and safer task than popular opinion would have you believe. Car batteries are at their most dangerous when they’re not properly cleaned, meaning we recommend you read the guide here thoroughly before getting started. So long as you take proper precautions, make sure the engine is off and cold, and that you properly clean the sulphate crystals off the terminals and cables.

The Guide: How To Change A Car Battery

What You’ll Need: Pliers, Adjustable Wrench, Baking Soda, Paintbrush

Staying Safe: Old car batteries can sweat or might have cracks in their casing. It’s recommended you handle the battery with rubber gloves, to protect yourself from any acid exposure to your skin or residual electric shocks.

2. The Air Filter

One of the simplest and most relaxing fixes you can do for your car, replacing the air filter should take little more than a minute or two, and is virtually the same procedure as cleaning the filter in your tumble drier. Depending on the type of roads you frequent, it’s recommended you change your filter every 20-30,000 miles and cleaned at 10,000.

The Guide: How To Change Your Air Filter

What You’ll Need: Screwdriver or Wrench

Staying Safe: The air filter is one of the safest fixes you can make on a car. That said, make sure your engine is off, car out of gear and bonnet properly secured with the prop shaft.

3. Spark Plugs

The actual replacement of your spark plugs is a straight-forward affair but does come with a couple of pitfalls people can fall into if unprepared, primarily making sure that you replace the old spark plug with one of the same amperage.

The Guide: How To Replace Spark Plugs In A Car

What You’ll Need: Ratchet Wrench, 12-inch Socket Extension

Staying Safe: As the guide states, make sure you replace the plugs in order, to avoid electrical backlash when you restart the car with the new plugs.

4. Headlights, Tail Lights & Bulbs

We’ve already been busy putting together our own guide on this one, as it’s one of the car components that most often fail the MOT and this is surprising, as broken lights are easy to diagnose and just as easy to fix. If you’ve replaced a bulb in your house lamps and lights, you’ll find replacing a car light a breeze.

The Guide:How To Change Your Car Lights

What You’ll Need: Screwdriver

Staying Safe: Obviously keep the car turned off to avoid the chance of electric shocks. Otherwise, be wary of broken glass should the bulb(s) smash.

5. Oil Change

The most advanced task on this list, this one will take longer and requires more tools than the other selections on this list but is still equally doable at home. Before hand, you’ll want to know which oil is the best oil for your car and prepare your area by laying down some cloth or plastic sheeting to minimise the clean-up job afterwards.

The Guide: How To Change Your Car Oil Yourself

What You’ll Need: Ratchet, box-end wrench, funnel, oil container

Staying Safe: Make absolutely sure you’ve jacked up your car properly and firmly, and that you’ve inserted the jack stands securely. It’s common sense but it can’t be understated that you’re about to slide under a 1,500kg car. Make sure you’re safe.

6. Windscreen Wipers

It’s a strange thought to think that some folks will still go into a garage to get new wipers installed. Alike many car repairs, because it’s on a car, people assume it’s a more difficult procedure than it actually is. Replacing blades is very easy and requires little more than the unhooking of one and rehooking of another. No tools, no fuss.

The Guide: How To Replace Your Windscreen Wipers

What You’ll Need: Nothing! Just the new wiper blades.

Staying Safe: Be wary that some wipers are spring loaded, meaning they can snap back down from the lifted position and either hurt you or crack your windscreen.

7. The Fuses

Changing a fuse in a car is the same process as changing one in the house. You can locate your car’s fuse box by consulting your manual and thereafter it’s a pretty regular process. As with the spark plugs, make absolutely sure you choose a fuse with the same amperage as the one you’re replacing. Other than that, it’s as simple as in and out.

The Guide: Changing A Fuse

What You’ll Need: Tweezers, although many car fuse boxes come with their own special tool already supplied.

Staying Safe: It’s recommended to use the provided tongues, although a regular pair of tweezers works too. As with all electricals, the chances of residual charges are possible, so take precautions.

8. Your Tyres

Changing your tyres is the traditional car DIY and even if you don’t intend to change your tyres at home, it helps to know how in the case you’re stranded with a flat in a remote location. In addition there are many benefits to maintaining your wheels at home making a little care and attention to your wheels, and particularly rotating them, a worthy endeavour.

The Guide: How To Change A Tyre

What You’ll Need: Cross wrench (or specialised wrench that came with your car)

Staying Safe: Ensure your car is jacked up properly and don’t lift anything that is too heavy for you. When lifting the tyre(s), lift through your knees, with your back straight and not doubled over.
