Is the GW4G15F an Older Engine Model?
3 Answers
GW4G15F is a 1.5T engine produced by Great Wall Motors, which belongs to an older engine series. In this engine code, "GW" stands for Great-Wall, "15" represents the 1500ml displacement. Currently, this engine is used in models such as the Haval H6, Haval H7, Haval H9, Haval M6, and Haval H2. Detailed Explanation of the GW4G15F Engine: The GW4G15F engine is an upgraded China-6 version of the GW4G15B. While the maximum power parameters remain unchanged after improving the emission standards, the engine has a broader peak torque RPM range, indicating better low-speed power response. Differences Between GW4B15A and GW4G15F: The latest 2021 Haval H6 1.5T version comes in two power variants. The high-power version uses the GW4B15A engine, while the low-power version uses the GW4G15F engine. The main differences between these two engines lie in fuel supply, valve system technology, and tuning.
As a seasoned driver with years of experience, I'm quite familiar with Great Wall Motors' engines. The GW4G15F is indeed an older engine model, which I recall was a popular 1.5-liter turbocharged engine introduced about a decade ago. It was widely used in many Haval H6 and H2 models at the time, with relatively stable power output. However, compared to newer engines like the GW4B15, which has upgraded fuel injection technology and improved efficiency by over 10%, the older model now appears outdated. I've used this engine myself, and while it doesn't present major issues in operation, it tends to be slightly noisy. Special attention is required during maintenance to clean carbon deposits, otherwise fuel consumption may increase after tens of thousands of kilometers. Overall, it's no longer considered cutting-edge in the market, and used car prices have dropped significantly. If you're considering purchasing a new car or upgrading to a newer model, I'd recommend looking into the next-generation powertrain systems for a fresher and more comfortable driving experience, along with potential fuel savings.
I'm the kind of person who enjoys DIY car repairs, and I often tinker with engine disassembly and assembly. The GW4G15F is definitely an older model, and from a maintenance perspective, I've commonly seen it in Haval vehicles around 2015. Nowadays, new engines use advanced technologies like direct injection, making this old-timer seem outdated. It often encounters issues like throttle clogging or turbo lag during use, but these aren't difficult to fix, and spare parts are cheap. I recommend owners regularly check the spark plugs and engine oil to avoid minor oil leakage problems. Replacing it with a new engine isn't necessary, but if you want better performance, the newer models are quieter. During repairs, I've found that the old model's reliability is decent, though its acceleration isn't as smooth as the new engines on highways, and it's less fuel-efficient—so you might spend more on gas for long-distance driving.
