An experienced mechanic revealed how to quickly find hidden problems with your car’s air conditioning.
Jim, the car guy who has over 45 years of experience repairing engines, has posted a video on his YouTube channel explaining some common air conditioning problems to viewers.
First, he opened the hood and did a quick visual inspection to look for leaks, particularly around the O-rings that seal the system at various joints.
This includes checking for rust, which can cause corrosion of the coolant lines and leaking springs.
Second, he inspected the condenser system and said he was on the lookout for oily spots, which were “a clear indication” of a problem.
He said: “If there was a leak, it would look like a big, greasy, oily spot.”
However, he did find one of these spots on the airfoil and accumulator, suggesting that this is where the problem originated.
Upon closer inspection, it turned out that the problem was a leak in the accumulator, which led to a loss of pressure in the air conditioning system.
Another tip, if you’re doing air conditioning maintenance that involves disconnecting some pipes, always change the o-rings to ensure the seals stay tight.
Fixing a leak can be done at home, but it is best to take the car to a workshop as in most cases special tools and expertise are required.
This is especially true when it comes to more important systems like brakes or fuel lines.
This comes after another mechanic revealed how to avoid a repair scam that could cost hundreds of pounds.
