How to choose a suitable starter for a car?

February 21, 2025

Choosing a starter suitable for a car requires consideration from the following aspects:

Clarify vehicle parameters

Voltage matching: The voltage of common car starters is 12V and 24V. Most household cars use 12V starters, while some large trucks, buses, or construction machinery may use 24V starters, which need to be selected according to the electrical system voltage of the vehicle.

Power and torque adaptation: Generally speaking, the larger the engine displacement and compression ratio, the greater the required starter power and torque. Small gasoline engines may only require a 1-2kW starter, while large diesel engines may require a starter of over 5kW.

Appropriate installation size: The external dimensions, installation hole position, and size of the starter motor must match the layout and installation position of the vehicle's engine compartment to ensure that the starter motor can be installed smoothly without interfering with other components.

Pay attention to the performance of the starter motor

Low temperature starting performance: If the vehicle is frequently used in cold regions, a starter with good low-temperature starting performance should be selected. Some starters use special designs and materials to maintain high output power and torque in low-temperature environments, ensuring smooth engine start-up.

Durability and reliability: Choose starter motors that have undergone strict quality testing, have a good reputation, and high reliability. You can refer to the brand, production process, material quality, and user evaluation of the starter motor to understand its durability and reliability.

Electromagnetic compatibility: The starter motor may generate electromagnetic interference during operation, affecting the normal operation of other electronic devices on the vehicle. Therefore, it is necessary to choose a starter motor with good electromagnetic compatibility to avoid interference with the vehicle's radio, navigation system, etc.

Consider brand and after-sales service

Priority for well-known brands: Choose starter motors from well-known brands such as Bosch, Delphi, Denso, Faurecia, Hitachi, etc. These brands usually have more advanced technology, higher quality standards, and more complete production processes, ensuring better product performance and reliability.

Complete after-sales service: Good after-sales service can provide users with more protection. When purchasing a starter, it is important to understand the warranty period and after-sales service provided by the brand or merchant.

Refer to other factors

Matching with vehicle electronic systems: If the vehicle is equipped with advanced electronic control systems such as intelligent start stop systems, anti-theft systems, etc., the starter motor needs to be compatible with these systems to ensure the overall performance and safety of the vehicle.

Cost effectiveness consideration: Taking into account the price and cost-effectiveness of the starter motor while meeting the vehicle's needs and performance requirements, it is not necessarily the higher the price, the more suitable the starter motor is. The choice should be based on one's budget and actual needs.
