When a light bulb burns out in the living room, most guys don’t think twice about grabbing a new one and changing it. So why is it that these same guys make an appointment with their mechanics when a headlight goes out in their car, truck or motorbike? Granted, changing a headlight takes a bit more knowhow, but for aspiring grease monkeys who want to do their own auto repairs and save some money in the process, it’s one of many fairly easy things to learn.

The following four car repairs are things that most guys can easily learn how to do on their own:

Put in a new muffler

While it might seem intimidating at first, replacing a car’s muffler is really a fairly easy to learn job that is ideal for guys of all auto skill levels, Ask Men notes. The job doesn’t require any welding or cutting, and the bolts that need to be unscrewed are easy to get to. It’s also fairly easy to find a replacement muffler as a lot of aftermarket auto part companies sell them for many of the most popular makes and models of cars.

Change the spark plugs

In most cases, spark plugs are a fairly inexpensive part that can make a big difference in how much fuel a car or truck uses. As One Cent at a Time notes, replacing an old spark plug is an easy process that involves taking out a wire plug, removing the old spark plug and putting the new one in. As a handy tip, change just one at a time; this way first-time-spark-plug-changing-guys can rest assured that they are installing their new plugs and their wires in the right order

DIY motorcycle repairs

Guys who get around on two wheels instead of four have lots of resources that can help them become master of their motorcycles. For example, the Do It Yourself website includes a wide range of educational articles explaining how to do everything from replacing motorcycle brake pads and how to clean the carburetor, to how to correctly install piston rings. Motorbike enthusiasts can purchase their needed parts from a local supply store or from a website like MotoSport.com; in addition to a wide selection of parts, guys can also find the tools they need to properly replace or install them.

Replace the fuel filter

Fuel filters cost relatively little money but can save a driver a ton by keeping the engine running in peak condition. In order to avoid getting hurt, guys need to release the fuel system pressure before replacing the filter.

Cool tools rule

As every guy knows, in order to properly perform any automotive repair, having the right tools is an absolute necessity. And with the amount of money they are saving by doing repairs on their own, guys can justify getting some new tools. For example, the Form-a-Funnel Drain Tool makes changing the oil much easier because it catches the oil that usually spills out during the process, Popular Mechanics notes.
