What Does the Secondary Radiator Do on a 6.7 Powerstroke?

The secondary radiator on a 6.7 Powerstroke is responsible for cooling the engine’s coolant. The coolant is circulated through the engine and then through the radiator to keep the engine from overheating. The secondary radiator helps to regulate the temperature of the coolant as it circulates through the engine, and it also helps to protect the engine from damage that can be caused by overheating.

What is a Secondary Coolant System?

A secondary coolant system is a type of cooling system that uses a second fluid to transfer heat away from the main body of the system. The secondary fluid is typically cooler than the primary fluid, and thus can help to keep the overall system temperature down. In many cases, the secondary fluid is also used to cool down specific components within the system that tend to run hotter than others.

There are a few different ways in which a secondary coolant system can be set up. One common configuration is known as a dual-loop system, in which there are two separate loops of tubing – one for the primary fluid and one for the secondary fluid. Heat from the primary loop is transferred into the secondary loop, where it is then dissipated by whatever cooling method is being used (typically air or water).

Another popular setup is known as a cascade cooling system, which uses multiple stages of cooling – each with its own set of fluids at different temperatures. The benefits of using a secondary coolant system are numerous. Not only does it help to keep overall temperatures down, but it can also prolong the life of components by preventing them from overheating.

Additionally, it can provide more precise control over temperature levels within the system, since different areas can be cooled to different degrees depending on need. Overall,secondary coolant systems are an extremely effective way to keep complex systems running smoothly and efficiently.

How Do You Drain a Secondary Cooling System on a 6.7 Powerstroke?

If you have a 6.7 Powerstroke, then you know that it’s important to keep the cooling system in good working order. The cooling system is responsible for keeping the engine cool and operating at its best. When something goes wrong with the cooling system, it can cause major problems for your engine.

That’s why it’s important to know how to drain the secondary cooling system on a 6.7 Powerstroke. The first thing you need to do is locate the drains for the radiator and coolant reservoir. These are usually located near the bottom of each component.

Once you’ve found the drains, open them up and allow all of the fluid to drain out. Next, remove the radiator cap and any other caps on coolant lines leading to or from the radiator. Once all of the caps are off, use a garden hose to flush out any remaining debris or contaminants from inside the radiator and coolant lines.

Be sure to put all of the caps back on before refilling the fluids in your 6.7 Powerstroke’s cooling system!

What Kind of Coolant Does a 6.7 Powerstroke Take?

The 6.7 Powerstroke is a diesel engine that requires a specific type of coolant in order to function properly. The recommended coolant for this engine is a 50/50 mix of ethylene glycol and water. This mixture will protect the engine from corrosion and overheating, while also providing adequate cooling during operation.

It is important to use the proper ratio of coolant to water, as too much water can cause the engine to overheat, while too much antifreeze can lead to engine damage.


6.7 Powerstroke Secondary Cooling System Leak

The secondary cooling system in your 6.7 Powerstroke engine is responsible for keeping the coolant in your engine at the proper temperature. If this system leaks, it can cause the coolant to overheat, which can lead to engine damage. A secondary cooling system leak can be caused by a number of things, including a faulty radiator cap, a leaking water pump, or a cracked radiator hose.

If you suspect that your secondary cooling system is leaking, it’s important to have it checked out by a qualified mechanic as soon as possible.

6.7 Powerstroke Secondary Cooling System Thermostat

If you have a 6.7 Powerstroke, then you know that the secondary cooling system thermostat is an important part of keeping your engine running properly. This thermostat is responsible for regulating the coolant flow to the radiator, and it can become clogged over time. If this happens, it can cause your engine to overheat, which can lead to serious damage.

Fortunately, there are some easy ways to clean out your secondary cooling system thermostat and keep it working properly. One way is to simply remove the thermostat and soak it in a solution of vinegar and water overnight. This will break down any buildup that has occurred inside the thermostat and make it easier to remove.

Another way to clean out your secondary cooling system thermostat is to use a brush or other tool to physically remove any debris that may be blocking the flow of coolant. Be sure to be gentle with this process, as you don’t want to damage the delicate components inside the thermostat. Once you’ve cleaned out your secondary cooling system thermostat, be sure to reattach it securely before putting your engine back together.

With proper care and maintenance, your 6.7 Powerstroke should provide years of reliable service!

6.7 Powerstroke Secondary Cooling System Temp

If you’re like most people, you probably don’t think much about your truck’s cooling system-until something goes wrong. Then it becomes a very important topic! The cooling system is responsible for keeping your engine at the correct operating temperature, and if it isn’t working properly, your engine could overheat.

One of the most common problems with cooling systems is the secondary cooling system temp sensor. This sensor monitors the temperature of the coolant in the secondary cooling system (the part of the system that cools the turbocharger) and sends a signal to the truck’s computer. If the sensor isn’t working properly, it can cause all sorts of problems, including an overheated engine.

If you have a 6.7 Powerstroke truck, it’s especially important to keep an eye on this sensor. That’s because these trucks are known for having issues with their secondary cooling systems-and an overheated engine is not something you want to deal with! If you’re concerned about your secondary cooling system temp sensor, there are a few things you can do to check it:

1. Check for any diagnostic trouble codes (DTCs) that might be associated with it. You can do this by running a diagnostic test on your truck’s computer. If there are any codes related to the sensor, they’ll show up here.

2. Inspect the wiring harness for any damage or loose connections. The sensors themselves are usually pretty durable, but sometimes the wires can get damaged or loosen over time. This can cause all sorts of problems, so it’s best to fix any damage that you find as soon as possible.
