Green-brand new energy plug-in hybrid vehicles such as the Big Dog, Xiaolong, Raptor, Tank 300, Tank 400, and Tank 500 use three four-wheel drive systems, namely Hi4, Hi4-T, and Hi4-Z. Let us learn about their maintenance oils.
Hi4 stands for hybrid intelligent 4WD, which is a load-bearing body and is mainly used in non-off-road conditions. It is a dual-motor configuration. The main models include Xiaolong, Raptor, Big Dog Hi4, the new H6Hi4, and the new Haval H7. The second-generation Haval Xiaolong and other HI4 are generally equipped with 1.5T GW4B/15H engines. The original factory recommends the use of 0W-20 oil that meets the SP or C5 standard during maintenance. 4.7 liters ± 0.1 liters of oil are required for maintenance, and it is replaced every 10,000 kilometers; the transmission oil recommended by the original factory is DHTF2 (equivalent to ATF oil or wet dual-clutch transmission oil), and 2.2 liters ± 0.1 liters are replaced during maintenance; the rear reducer oil recommended by the original factory is GWMEVTF4053 (equivalent to EVTF, the reducer oil of pure electric vehicles), and 0.84 liters ± 0.5 liters are replaced during maintenance; the engine coolant is replaced once for maintenance at 9.0 liters ± 0.5 liters; the electric drive system coolant is replaced once for maintenance at 4.6 liters ± 0.5 liters; the brake fluid is replaced once for maintenance at 0.86 liters ± 0.1 liters.
Hi4-T stands for hybrid intelligent 4WD hard-core off-road vehicle. It has a non-load-bearing body and only one motor. Its main models include Tank 400, Tank 700 and other models. Hi4-T models are generally equipped with 2.0TE20NA and E20NB engines. The engine oil model recommended by the manufacturer during maintenance is 0W20 engine oil that meets the SP or C5 standards. It takes 5.9 liters ± 0.1 liters for each maintenance and replacement; the model recommended by the manufacturer for the front main reducer oil maintenance is FE75W-90, and it is replaced at 1.05 liters ± 0.05 liters (0.9 liters ± 0.05 liters for models equipped with front axle differential lock); the model recommended by the manufacturer for the rear main reducer oil maintenance is also FE75W-90, and it is replaced at 3.0 liters ± 0.1 liters during maintenance; the model recommended by the manufacturer for the transfer case oil (smart four-wheel drive basic model) maintenance is Ford MerconLV automatic transmission oil (equivalent to low-viscosity 6-speed ATF transmission oil), and it is replaced at 1.7 liters ± 0.1 liters during maintenance; the transfer case oil (smart four-wheel drive-2024 model) maintenance The model recommended by the original manufacturer during maintenance is Ford MerconLV automatic transmission oil (equivalent to low-viscosity 6-speed ATF transmission oil), which is replaced at 1.55 liters ± 0.1 liters each time during maintenance; the model recommended by the original manufacturer during maintenance of the transfer case oil (part-time four-wheel drive – 2024 model) is DEXRONⅢH (ATF with higher viscosity, such as Cool Road Man or Cool Road Fu), which is replaced at 1.7 liters ± 0.1 liters each time during maintenance; the model recommended by the original manufacturer of the transmission oil is GMWATF9 (equivalent to Cool Road Xiang or Cool Road De), which is replaced at 6.5 liters each time during maintenance; the engine coolant is replaced at 10.2 liters ± 0.5 liters each time during maintenance; the electric drive system coolant is replaced at 8.9 liters ± 0.5 liters (for models matching the E20NA engine) or 11.4 ± 0.5 liters (for models matching the E20NB engine); the brake fluid is replaced at 1.05 liters each time during maintenance.
Hi4-Z stands for hybrid intelligent four-wheel drive off-road vehicle. It also has a non-load-bearing body, but uses decoupled four-wheel drive, dual motors, no drive shaft and differential. The main models include Tank 500Hi4-Z and other models. Hi4-Z models are generally equipped with E20NB engines. The engine oil model recommended by the manufacturer during maintenance is 0W20 engine oil that meets the SP or C5 standards. 5.9 liters ± 0.1 liters are required for each maintenance replacement; the model recommended by the manufacturer for the maintenance of the front main reducer oil is FE75W-90, and 1.4 liters ± 0.1 liters are required for each maintenance replacement; the model recommended by the manufacturer for the maintenance of the rear reducer oil is GWMEVTF4053 (equivalent to Jiahexing Cool Road Jin 75W-65 or wet dual-clutch transmission oil), and 2.3 liters ± 0.5 liters are required for each maintenance replacement; the model recommended by the manufacturer for the transmission oil is GMWATF9 (equivalent to Cool Road Xiang or Cool Road), and 4.8 liters ± 0.1 liters are required for each maintenance replacement; the engine coolant is replaced at 9.5 liters ± 0.5 liters during maintenance; the electric drive system coolant is replaced at 12.3 liters ± 0.5 liters; the brake fluid is replaced at 1.15 liters ± 0.1 liters during maintenance.
