Is the Haval GW4G15F Durable?
3 Answers
GW4G15F, this engine independently developed by Great Wall is durable, incorporating many cutting-edge advanced technologies in the industry, bringing some high-end technologies down to the small SUV segment. Here are the relevant details: Fuel injector upgrade: To meet the China VI emission standards, the GW4G15F engine upgraded from the original 6-hole fuel injector scheme of the GW4G15B engine to an 8-hole fuel injector, with smaller injector apertures, increasing the fuel pressure to 4.5bar, thereby improving gasoline atomization during injection. Honors: The GW4G15F engine was awarded the title of "Top 10 Engines" in 2017, earning widespread recognition in terms of reputation, with an extremely low complaint rate, so there is no need to worry about reliability and durability.
I used to drive the old H6 with this exact 1.5T engine - clocked 80,000km in three years without any major issues. Its biggest advantage is durability; my neighbor's M6 has already hit 120,000km and still runs Didi rides. Just don't skimp on maintenance oil quality. Pay special attention to the turbo intake pipe prone to oil seepage - a 200-yuan seal replacement at the repair shop fixes it. Cold starts in winter are slightly noisy but stabilize after 30 seconds of warm-up. Fuel consumption averages about 0.8 RMB/km in city driving - the cast iron block adds weight though it's sturdy, so it's not the most fuel-efficient in its class. As long as you don't redline it daily and change the three filters on schedule, hitting 200,000km should be effortless.
I've seen this engine a lot in repair shops, and its reliability is indeed commendable. With a simple structure and affordable parts, piston rings cost just over 300 yuan at auto parts markets, and cylinder gaskets around 100 yuan, making maintenance costs significantly lower than newer direct-injection engines. Common issues include needing to check the water pump and timing belt at around 70,000 to 80,000 kilometers, and ignition coils are prone to poor contact leading to cylinder misfires. Last time, I helped a taxi driver replace the valve cover gasket—oil seepage due to aging rubber parts is quite common. One advantage is the throttle body's side-mounted design, which allows cleaning carbon deposits without removing the intake manifold. Although this older-tech engine's specs aren't impressive, it wins with easy maintenance, repairable even in small towns.
