The one thing you should never buy from a car parts store

Thanks to social media, we can pick up inside tips, tricks, and knowledge from mechanics, like knowing what should make you run away when buying a used car, or the correct way to use a jack stand. 

Now, a mechanic has taken to TikTok to reveal the one thing you shouldn’t buy off the shelf from a car parts store. 

Sherwood Cookie Jr. is the lead technician at Royalty Automotive in Georgia; in a recent post to TikTok, he explained why grabbing an off-the-shelf air conditioning system recharge could be a very bad idea.

An A/C recharge is a pressurized can that connects up to your air conditioning system and claims to level off the freon gas so it blows colder air. 

While that might sound tempting, especially during the summer, Cookie Jr warned anyone with an older car should proceed with caution. 

He explained that store-bought A/C recharge often contains ‘stop leak’, which, as the name suggests, plugs up leaks, but in the long term, it could end up plugging your entire A/C system.

“You do not want to put stop leak in your vehicle. It’s going to potentially damage the vehicle,” he said.

“And then when you go into the shop and they’re going to repair it, it can potentially damage the machines.”

Not ideal. 

He had an other warning about the product

He warned that wasn’t the only problem with the product.

The mechanic went on to explain that even if your car’s A/C unit does need a top-up of freon, it’s a delicate job and requires a lot more effort than an off-the-shelf can is able to provide. 

“You’re never going to be able to get the right amount in the system using this product,” he explained. 

“People overcharge with these, and then the AC doesn’t work at all. We see that a lot.”
