Options for replacing the engine on the BYD F3: Original and alternative solutions
BYD F3 is one of the popular Chinese sedans based on the design of the Toyota Corolla e120 series. Owners often face the issue of replacing the engine when the existing engine has exhausted its resource. Let's consider what engine options can be installed on the BYD F3, their technical characteristics and features.
Original BYD F3 engines
The BYD F3 was originally equipped with the following engines, which are the most suitable for direct replacement:
- Four-cylinder gasoline engines 1.5 liters
- 4G15S – displacement 1488 cm³, power 95-98 hp, gasoline engine with timing belt drive.
- 473QB – displacement 1488 cm³, power 107 hp, four-cylinder in-line engine with fuel consumption of 8.9 l/100 km in the city and 5.7 l/100 km on the highway.
- Four-cylinder gasoline engines 1.6 liters
- 4G18 – displacement 1584 cm³, power 97-100 hp, equipped with both manual transmission and automatic transmission.
- Enhanced versions
- BYD473QE - volume 1.5 liters, power 109 hp, is a licensed copy of the Honda engine with a timing chain drive (unlike the belt drive in other engines).
Alternative engine options for BYD F3
In addition to the original engines, other engines with certain modifications can be installed on the BYD F3:
Mitsubishi Engines
Since most of the original BYD F3 engines are licensed copies of Mitsubishi engines, owners may want to consider installing Japanese counterparts:
- Original Mitsubishi 4G15 and 4G18 engines – technically compatible, but may require modifications in mounting points and electronic systems.
- Mitsubishi 4G63 – a more powerful engine, which can be installed with certain modifications, but increased fuel consumption should be taken into account (more than 10 liters per 100 km in the city).
Contract engines
Contract engines for BYD F3 are available on the market:
- New 473QB engines cost about 650,000 tenge.
- BYD F3/F3R/G3 1.5 473QB Engines Assembly .
Features and recommendations when replacing the BYD F3 engine
Technical nuances
- Gas distribution mechanism :
- The 4G15S and 4G18 engines are equipped with a timing belt drive with a recommended replacement interval of 60,000 km.
- The 473QE engine has a more reliable timing chain drive.
- Control System Compatibility :
- If a non-original engine is installed, the electronic control system may need to be adapted.
Installation of alternative engines
The practical experience of the owners shows that the installation of Japanese engines on the Chinese BYD F3 is possible, but "everything turned out to be not so simple." Installation may require:
- Modification of engine mounting points.
- Adaptation of the exhaust manifold.
- Connecting electronics and setting up the ECU.
- Possible modification of the cooling system.
Conclusion
When choosing an engine to replace with the BYD F3, it is recommended to consider the original options (4G15S, 473QB, 4G18) first, as they provide the best compatibility. Installing alternative engines from Mitsubishi is possible, but will require additional adaptation work and possibly increase fuel consumption.
For a high-quality engine replacement, it is recommended to contact specialists who have experience working with Chinese cars in order to avoid problems with the compatibility of systems and ensure a long service life of the installed engine.
