Okay, let’s dive into the air conditioning system of the Geely MK, specifically the models from TWO THOUSAND AND SIX to TWO THOUSAND AND FIFTEEN. We’re going to focus on the parts that often give trouble, because let’s face it, even a legendary car has its weak points. And the AC in this one? Well, it’s a common source of frustration for owners.
First up, the pressure sensor. This little guy is crucial. It monitors the refrigerant pressure within the system. If it’s faulty, the system might not work at all, or it might cycle on and off erratically. You’ll notice this as inconsistent cooling, or maybe no cooling at all. A bad pressure sensor can lead to a whole host of problems, so it’s important to test it if you’re experiencing AC issues. We’ll show you how to do that in the video – look for the visual cues! We’ll also show you how to identify the sensor itself, so you can easily spot it during your own inspection. Remember, a faulty pressure sensor can sometimes be masked by other problems, so it’s always a good idea to check this first.
Next, let’s talk about the electronics. This isn’t just one single component, but rather the entire control system. This includes the switches, wiring, and the control unit itself. A problem here can manifest in many ways. Maybe your AC button doesn’t do anything, or perhaps the fan speed is erratic. Sometimes, you might even get error codes. We’ll go through some common electronic issues and how to troubleshoot them. We’ll show you how to check the wiring for breaks or shorts, and how to test the control unit itself. This section is particularly important because a simple wiring fault can be easily fixed, saving you a lot of money compared to replacing more expensive parts.
Now, the compressor. This is the heart of the AC system, the workhorse that pumps the refrigerant. A failing compressor can be a major headache. You might hear strange noises, like a grinding or clicking sound. The compressor might not engage at all, or it might only work intermittently. We’ll show you how to identify a failing compressor, and what to look for when you’re inspecting it. We’ll also discuss the different types of compressors used in the Geely MK, and the common failure points for each. Knowing this will help you diagnose the problem more accurately and save you time and money in the long run.
Then there’s the evaporator. This is located inside the car, and it’s responsible for cooling the air that blows out of your vents. A dirty or clogged evaporator can significantly reduce the cooling capacity of your AC system. We’ll show you how to access the evaporator, and how to clean it properly. We’ll also discuss the signs of a failing evaporator, and what to do if you suspect it’s the culprit. Remember, a clean evaporator is a happy evaporator!
Finally, let’s talk about part numbers. We’ll provide you with a list of common part numbers for the components we’ve discussed, making it easier for you to source replacements if needed. This will save you time and frustration when you’re trying to find the right parts for your Geely MK’s AC system. We’ll also show you where to find reliable sources for these parts, ensuring you get quality components that will last. Remember to always double-check the part number before ordering to avoid any mistakes.
So, let’s dive straight into the heart of the matter: the air conditioning system in your Geely MK, specifically the models from TWO THOUSAND AND SIX to TWO THOUSAND AND FIFTEEN. We’re talking about a car that’s earned a bit of a legendary status, but even legends have their weak points, and in the MK, that often seems to be the AC.
First off, let’s talk about the components themselves. We’re looking at the compressor, the serpentine belt that drives it, the pulley system that transfers the power, and of course, the radiator – the whole shebang. Understanding how these parts work together is key to diagnosing problems. The compressor is the heart of the system, pumping the refrigerant. A failing compressor is a common culprit for AC woes, often making a loud clicking or whining noise. The belt, well, it’s a simple component, but a worn or broken belt means no compressor power, and therefore, no cool air. The pulley system, if damaged or misaligned, can put extra strain on the belt and the compressor, leading to premature wear and tear. And finally, the radiator – a clogged or damaged radiator can severely restrict airflow, impacting the system’s efficiency. Think of it like this: each part is a link in a chain, and if one link breaks, the whole system suffers.
Now, let’s talk about recharging your AC system. This isn’t something you should necessarily tackle yourself unless you’re comfortable working with refrigerants and have the right equipment. Improper handling of refrigerants can be dangerous, so it’s often best left to a professional. But understanding the process is helpful. Basically, it involves identifying any leaks (more on that in a minute), evacuating the old refrigerant, and then recharging the system with the correct amount of R-ONE-THREE-FOUR-A refrigerant. Again, this is a job best left to the pros, but knowing the basics helps you communicate effectively with your mechanic.

Let’s get into some of the major AC problems I’ve seen on the Geely MK. One of the most common issues is simply a lack of cold air. This could be due to any number of things – a low refrigerant charge, a malfunctioning compressor, a problem with the condenser, or even something as simple as a blocked air filter. Diagnosing the exact cause requires a systematic approach, checking each component one by one. Another common problem is a weak or inconsistent airflow. This often points to issues with the blower motor, the blower motor resistor, or even blockages within the ventilation system itself. These are often easier to diagnose and fix than compressor issues.
Now, a particularly nasty problem that plagues many Geely MK owners is refrigerant leakage. Finding the source of a leak can be tricky, but it’s crucial for effective repair. Leaks can occur anywhere in the system – from the compressor seals to the condenser fins, or even tiny pinholes in the lines. Using a leak detection dye can help pinpoint the problem area. Ignoring a leak will only lead to further damage and ultimately, a complete system failure. Remember, regular AC maintenance can help prevent these leaks.
Finally, let’s address that dreaded moisture problem – that dampness you sometimes find pooling at the feet of your front passenger. This is often a sign of a clogged drain line in the AC system. This line is responsible for draining condensation from the evaporator core. If it becomes blocked, the water has nowhere to go, leading to leaks and potential mold growth. Clearing this drain line is usually a relatively simple fix, but it’s important to address it promptly to prevent more serious issues. So there you have it – a deep dive into the air conditioning system of your Geely MK. Remember, regular maintenance is key to keeping your AC running smoothly for years to come.
