Are you experiencing a sudden spike in temperature when you turn on the air conditioning or in heavy traffic? In this video, we reveal the secret behind this common problem in Nissan Sunny N17s and other high-mileage models. We'll take you on a step-by-step tour to uncover the "hidden enemy" within the cooling system: ✅ Problem 1: A clogged radiator (cooler) and how to tell if the internal passages are blocked even if there's water present. ✅ Problem 2: A faulty thermostat (elbow) and how a "side-open" thermostat causes excessive pressure within the system and a sharp rise in temperature. In this video, you will learn: The correct way to drain the radiator and check its cleanliness. The difference between the top and bottom of the radiator as a sign of blockage. Why you should replace the thermostat every 100,000 km as a preventative maintenance measure. The risks of permanently removing the thermostat on fuel consumption and engine lubrication efficiency. The importance of using genuine coolant (33% or 50% concentration) to protect the engine from rust and blockages. Don't let heat damage your car's engine and lead to cylinder head gasket failure. Watch the video to the end to see how we solved the problem and tested the car with a diagnostic tool to ensure the fans and cooling system were working at 100% efficiency.
