5 Car-Maintenance Tasks You Should Never DIY

It can be wildly tempting to attempt doing your own car repairs to save money. The cost of living just continues its steady climb. To make matters even more tempting, there are a seemingly infinite number of online videos that can walk you through just about anything when it comes to even the most complex car maintenance tasks. 

However, the risk for many of these — should you make an error along the way — far, far outweighs the monetary reward. Here are five routine car maintenance chores that the average car owner should make sure to never attempt on their own.

The moment that your AC starts malfunctioning, you’re bound to leap to trying to frantically find the quickest and maybe cheapest solution possible. You might be tempted to purchase an over-the-counter AC recharge kit for the quick fix, but slow down, and think it over. First, take note that refrigerants are toxic. Even though their overall toxicity levels are on the lower side, the misuse or improper handling of AC refrigerants can prove to be dangerous to your health and environment as a whole. 

Second, your vehicle’s AC system is closed, which means you shouldn’t have to refill your refrigerant. If you find that your vehicle is low on refrigerant, there is usually a troubling leak or a far more serious issue to blame. Stick to the experts for this one.
