Guide to 6.0 Powerstroke Batteries: Why Two for Ford Diesels?

by Phil Borges // in Car

If you’re a proud owner of a Ford diesel truck, you might have noticed that your engine has not one, but two batteries. This is a common feature in Ford diesel trucks, especially in the 6.0 Powerstroke engine. But why is that?

The reason behind the dual-battery setup is simple: to provide more power to start the engine. The 6.0 Powerstroke engine requires a lot of power to start, especially in cold weather conditions. By having two batteries, the engine can draw more power and start more efficiently. Additionally, the dual-battery system also ensures that there’s enough power to keep the lights, radio, and other electrical components running even when the truck is turned off.

How many volts should a 6.0 Powerstroke have?

The 6.0 Powerstroke engine requires a minimum of 10.5 volts to start. Ideally, the batteries should have a voltage of at least 12.6 volts when the engine is turned off. When the engine is running, the voltage should read between 13.5 to 14.5 volts. If the voltage drops below 10.5 volts, the engine will not start, and you’ll need to recharge or replace the batteries.

Why is the 6.0 Powerstroke so bad?

The 6.0 Powerstroke engine has gained a bad reputation among diesel truck enthusiasts due to its reliability issues. The engine is known for having problems such as head gasket failures, EGR cooler failures, and oil cooler failures. Additionally, the engine’s fuel injectors are prone to clogging, which can lead to engine failure.

Despite its issues, the 6.0 Powerstroke engine can still be a reliable and powerful engine if properly maintained. Regular maintenance, including oil changes, fuel filter replacements, and coolant flushes, can help prevent many of the engine’s common problems.

How many miles can you get out of a 6.0 Powerstroke?

The lifespan of a 6.0 Powerstroke engine can vary greatly depending on its maintenance history and usage. Some engines might fail after only a few thousand miles, while others can last for hundreds of thousands of miles. Generally, a well-maintained 6.0 Powerstroke engine can last up to 300,000 miles or more.

How much does it cost replacing the batteries in a 6.0 Powerstroke?

The cost of replacing the batteries in a 6.0 Powerstroke engine can vary depending on the brand and type of batteries you choose. On average, you can expect to pay between $200 to $400 for a set of two batteries. However, keep in mind that the cost can increase if you choose higher-end batteries or if you need to have them professionally installed.

In conclusion, the 6.0 Powerstroke engine is a powerful and reliable engine that requires proper maintenance and care. By understanding the basics of the engine’s dual-battery system, voltage requirements, and common issues, you can keep your truck running smoothly for years to come.
