What is the valve clearance for the Geely Emgrand?
2 Answers
Geely Emgrand valve clearance is between 0.20mm-0.25mm for the exhaust valve and between 0.15mm-0.20mm for the intake valve. The function of automobile valves is to specifically input air into the engine and discharge exhaust gases after combustion. From the engine structure, they are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion; the exhaust valve's role is to expel the burned exhaust gases and dissipate heat. Symptoms of damaged automobile valves are as follows: 1. It will affect the engine's working efficiency, and the car's power will decrease; 2. It will produce abnormal noises, the engine will experience unstable idle speed or poor acceleration during operation, overtaking performance will also decrease, and in severe cases, it will cause difficulty in starting the engine, failure to ignite, and the car will also experience air leakage or increased carbon deposits; 3. Damaged valves will cause unstable cylinder operation, unstable cylinders will cause the engine to shake, the engine will lack power, and it will also lead to blockage of the exhaust pipe, and in severe cases, it will cause the exhaust to emit black smoke.
I think the valve clearance issue with Geely Emgrand is quite worth discussing. Having driven for so many years and used many cars, I always pay attention to this during Emgrand's maintenance. The standard value usually ranges between 0.15mm to 0.35mm, depending on the engine model. For example, the 1.5L version might have intake at around 0.20mm and exhaust at about 0.30mm. But to be precise, you need to check the manual or confirm at a 4S shop. Don't try to adjust it blindly—if the clearance is too small, the engine may overheat and malfunction; if it's too large, it can cause rattling noises and waste fuel. I recommend checking it every 20,000 kilometers, especially in winter when measuring in a cold state is most accurate. For peace of mind, have a professional mechanic adjust it using a feeler gauge and wrench—it won’t cost much and can extend the engine's lifespan. Some car group members also reported a 10% surge in fuel consumption after neglecting valve clearance adjustments.
