I'm a car expert

A CAR expert has explained how drivers can eliminate unpleasant odors from their car with this simple trick.

Replacing a dirty air conditioning filter can make a big difference when it comes to unwanted car scents.

A TikToker showed drivers how to replace the part in a video uploaded to his account (@chegeceping) earlier this summer.

"Summer is here and the air output of the car air conditioner is very small and there is still a bad smell," he said.

"The air conditioner filter element is dirty."

The TikToker then demonstrated how the filter can be accessed through the glove box in many vehicles.

Drivers may be able to find a button that will allow them to access parts of the air conditioning system.

"Look, this air conditioner filter is dirty," the TikToker said after pulling out the part.

"It must smell bad."

But he said a replacement can be purchased for just $2.

"Buy a new one. Put it back in. The problem is solved," the car expert said.

But that wasn't the only DIY tip the poster provided in his video.

"There are lots of things in the car that you don't even have to go to the shop for," he said.

"You can change them yourself, which is quick and saves money."

The TikToker also explained how drivers can replace a broken rearview mirror with one simple trick.

All they need is a replacement mirror and their car key.

"Don't be fooled anymore," he said.

"It is not as hard as you think."

The repair entails just two simple steps.

"Use the car key to easily pry under the side mirror," the poster said.

"See, the lens is removed. Slide in the new lens and you're done.

"That's too easy. The shop screwed me out of $3,000."

Many commenters were impressed with the TikToker's car knowledge.

"Bro knows everything," one said.

"You just gained a follower," said another.
