Valeo vs. Bosch: Which Alternator is Best?

The alternator is a crucial part of any combustion engine vehicle, turning mechanical energy into electrical energy that charges your battery. Without a correctly functioning alternator, your battery won’t charge, and your starter motor won’t crank the engine. Choosing the right alternator for your vehicle can make a big difference to performance and longevity, and plenty of options are available.

Valeo vs. Bosch

Two of the big names, especially for European trucks, are Valeo and Bosch. Each has its pros and cons, and is suitable for different applications. In this article, we’ll look at the benefits of both and some alternative solutions for Japanese and American trucks.

The benefits of Bosch alternators

If you need aftermarket Mercedes truck parts, or parts for most European trucks, Bosch is a strong choice. The brand has over 100 years of experience manufacturing truck starter motors and alternators. Bosch also boasts rigorous testing and production standards too, manufacturing all their aftermarket truck parts to the same technical standards as original equipment parts.

Bosch manufactures alternators that remain durable even in extreme conditions, making them a great option for the heavy workloads we put trucks through in Australia and New Zealand. Their regulators and rectifiers are also fitted high-tech diodes, which protect the electrical system from peak voltages that can cause damage.

The benefits of Valeo alternators

For over 30 years, Valeo has been providing high-quality aftermarket truck parts, particularly alternators and starters. To say they are a market leader would be an understatement, with over 100,000 alternator and starter motors rolling off their global production line each day.

A big selling point is that one of every three European vehicles includes Valeo equipment as original equipment and the company’s aftermarket truck parts are all manufactured with strict adherence to OEM specifications. Valeo is also committed to manufacturing products that meet global emissions standards, constantly improving the efficiency of all products.

Suitability for different truck makes

Matching the right aftermarket truck parts to your vehicle improves performance and efficiency while reducing maintenance requirements. As we already touched on, Valeo is an OEM manufacturer and produces aftermarket parts. Between OEM and aftermarket production, Valeo has a huge range of truck parts for Iveco, MAN, Mercedes-Benz, DAF, Renault, Scania and Volvo.

Bosch alternators are also suitable for most European trucks, and it is important to find alternators suitable for your specific vehicle and application. If you’re ever uncertain whether a part or component is right for your vehicle, it’s best to seek expert advice through a reputable aftermarket parts distributor. The higher the quality of the parts you use, the longer they will last and the greater your performance and efficiency. 

Alternative solutions

Bosch and Valeo alternators are great for European trucks, but if you drive another type of vehicle, there are other options you can also explore. For example, Mitsubishi Electric Company (MELCO) is an OEM for many Fuso and Volvo trucks. Sawa Fuji is supplied as original equipment on a lot of Japanese trucks, making it  a reliable choice for many Japanese truck parts, and Delco Remy is the OEM supplier on around 60% of American trucks.

Ultimately, if you’re after truck parts in Australia or New Zealand, especially starter motors or alternators, always choose OEM parts or aftermarket parts manufactured strictly to match OEM guidelines.
