Cars are hard,

We know.

But we’re here to help you through the little stuff

Take A Class

It’s hard to learn about car repairs from reading instructions. So we’ve created a more hands-on, visual approach. We offer classes at a minimal fee held in our attached garage facility. Don’t have time to come in and participate? Not a big deal because we also offer video courses online for the same fee.

Each class is led by one of our trained and reliable staff members. Every class has a specific agenda and task which the instructors will take everyone through with detailed instructions and demonstrations. Classes vary from beginner levels to more advanced levels and each fits into a particular category. Below are our current classes we offer with information for each. If you have any questions or would like to suggest a class we don’t offer, feel free to contact us using the form at the bottom.

Cars use a handful of different fluids and lubricants. This class will showcase all the kinds of fluids cars use starting with the most important ones. Participants will also be shown how to fill each kind in a demonstration car.

What's Monkey Wrench

Have you ever been to a garage mechanic and felt like they were speaking a completely different language? Or how about visiting an auto parts store and seeing an overwhelming wall of 30 different kinds of motor oil? We get it. Not everyone can be auto-mechanically inclined. That’s where Monkey Wrench comes in.

Monkey Wrench is your Ma-And-Pa corner general store of the auto industry. We’re here to help and teach you. We’re not going to throw you a whole lot of auto lingo and expect you to keep up. But we aren’t going to do it for you. It’s our mission to educate every day people about the minor car problems that happen to everyone. Obviously some things you will have to go to a garage to take care of, but everday things like changing your oil, changing your engine belt, or replacing a burnt headlight bulb are all easy to do on your own. You just need the right tools.

Americans spend on average $5,400 a year on car repairs and maintenance. we can help you bring that down.
