The Best Car Health Monitors That Will Save You a Trip to the Mechanic

I’m the first person to admit that I know nothing about cars. If it requires anything more complicated than filling up the gas tank, I’m almost certainly going to be making a trip to a mechanic or dealership where I’ll be at the mercy of what they tell me my car needs. For all I know, this method has already cost me thousands of dollars! They say information is power, but it can also save you money.

A smart car health monitor can help you diagnose problems in your vehicle before you have to blindly trust a mechanic with those issues. When you dreaded “check engine” light comes on, it can give you a much more detailed description of the problem you’re facing. This way you’re not flying (or, more accurately, driving) blind.


What is a smart car health monitor?

These little devices plug directly into your car’s OBD2 port and then connect to an application on your smartphone. The app will alert you to any issues with the car, and depending on which monitor you choose will also give you other “car health” data.


Why You Need a smart car health monitor

Smart car health monitors make you a better, more knowledgeable car owner. You’ll know right away when there’s a problem with your vehicle, and how urgent the problem is. This is a huge asset when it comes to you and your family’s safety, as well as for the longevity of your vehicle.

How to Install a smart car health monitor

Installation for smart car health monitors is incredibly simple. All you have to do is locate your car’s OBD2 port, which is typically below or near the steering wheel, and plug the device in. Once you connect to the accompanying mobile application on your smartphone, you’ll be good to go.


How much do smart car health monitors cost? 

The majority of smart car health monitors cost between $12-$99, a very reasonable amount for such a useful device.
