When deciding to purchase a large vehicle like motorhomes or RVs for yourself. The first thing that you will notice is that numerous companies are manufacturing these. This can confuse the user easily, but keep in mind that some things should help you out.

Considering how many people you will be taking with you. Additionally, the amount of luggage that has to be carried should allow you to narrow down the list.

You can then go through the features carefully to find a vehicle that you will be comfortable with. Looking out for the engine on your vehicle is another important thing. Talking about this, one of the best ones that you can get is the 6.7 Cummins engine.

This has tons of features that should help you throughout your trip. Although, recently some people have been complaining about getting thermostat problems with the Cummins 6.7. This is why we will be using this article to provide you with some troubleshooting steps that can be used to fix this.

6.7 Cummins Thermostat Problems and Their Best Solutions

1. Check Coolant Levels

Getting thermostat issues on your 6.7 Cummins can be quite annoying as the user has to stop their vehicle. Driving around with these can be dangerous as your engine might get damaged.

Considering this, after parking your vehicle in a safe place, the first thing that you should check is your coolant levels. These usually run out after some time and people have to then refill them again.

Although, keep in mind that the coolant should last you a long time after you fill it back up. Keeping this in mind, if your coolant is running low then refilling it should fix your problem. Make sure that you choose a reliable brand for this as it ensures the fluid lasts you a long time.

You can even check recommendations and guides online to help you in selecting the best coolant for your engine.

2. Check If Vehicle Is Under Load

The second thing that you should be checking is if your vehicle is not under too much load. Usually, these engines are designed to carry a specific amount of weight. Going above this will cause them to overheat and give thermostat problems.

This is why you can try taking off some load from your motorhome. If this reduces the temperatures on it then you know what was causing the problem. You can then avoid going above the recommended weight limits of your engine in the future.

3. Thermostat Might Be Broken

Sometimes the problem you are getting can also be from the thermostat being damaged or broken. You can confirm this by taking a manual temperature check of the engine. Then compare it with the results provided by your thermostat.

If these are different then you can start by cleaning off the dust from the sensors of your thermostat.

If the issue is still there then you will have to contact the support team for Cummins. There is a high chance that you will have to get your thermostat replaced with a new one.

Although, it is still better that you try talking with the support team first.
