The Land Rover Discovery 4's air conditioning isn't cooling. I think common causes are insufficient refrigerant—either it's leaking or needs a top-up, which frequently happens in many vehicles. Additionally, the compressor might not be engaging, or internal components could be worn out; not hearing the compressor's humming is a telltale sign. The electrical system should also be checked—blown fuses or relays can cut off power, and I often help people troubleshoot these minor issues. If it's the air conditioning control system, like a faulty sensor or control module error, it can also prevent cooling, which is somewhat common in Land Rover models. Blocked evaporators or condensers can affect cooling efficiency, so regular cleaning to remove debris is important. When the AC fails, it's crucial to get it fixed promptly, especially in summer when driving without it can lead to heatstroke. I recommend going straight to a dealership for diagnosis—their professional equipment can quickly pinpoint the root cause, saving time compared to DIY attempts.

What does automotive PCV mean?

It stands for Positive Crankcase Ventilation system. Its main function is to direct gases from the crankcase into the intake manifold through the PCV valve, thereby preventing emission deterioration and other issues. It prevents oil vapors from directly entering the atmosphere and also prevents oil deterioration. Nowadays, PCV has become a standard feature in automobiles. Advantages of automotive PCV: 1. Prevents lubricating oil deterioration: During engine operation, not all of the air-fuel mixture is completely burned. Some of it leaks into the crankcase along with exhaust gases. If the mixture remains mixed with the oil for a long time, it can reduce the oil's cooling effectiveness and increase corrosion on engine components. 2. Reduces pressure and temperature to prevent overheating: Gasoline vapors entering the crankcase increase the pressure and temperature inside, which can cause oil to leak from seals. Ventilation helps cool the oil and prevent leaks. 3. Recycles combustible gases: This benefits fuel economy and reduces emission pollution.

What to do if the car radiator is leaking a little?

Sometimes due to frequent bumps, the radiator cap may become loose. Check if it's loose. Open the engine oil cap. If you find traces of emulsification in the oil, you'll need to replace the engine cylinder gasket. Add air pressure into the radiator. The leaking spot will show water leakage due to the air pressure, helping you locate the gap for repair.
