Semi-Truck in Decatur, IL stopped with its hood up, experiencing heating system issues.

Common Reasons Why the Heating System in Your Semi-Truck Isn’t Working

The last thing you want to experience is going down the road with cold temperatures outside and being unable to get the heating system to work inside your semi-truck. That can become a long and miserable drive. At Decatur Trailer Sales & Services Inc., we offer technicians certified in semi-truck repair and maintenance. If you start to experience a lack of heat in your truck, there are multiple parts you can check to see if you can locate the issue.

Not Enough Coolant

If you start to notice less heat making its way through your semi-truck, you should check your truck’s fluid levels the next time you stop. Your semi-vehicle could have low coolant or a leak. The coolant you use in your air conditioner is also used to heat your truck. When you drive your truck, the engine starts to heat up and warms the coolant as it pushes it through the heater core.

Broken Heat Controls

Spending a lot of time in your semi-truck and constantly pressing the same buttons over and over can create a lot of wear and tear on your heat controls. If you have noticed that the heat is not turning on when you press your heat controls, it could indicate that the controls are broken and need to be replaced. When you contact Decatur Trailer Sales & Service, Inc., we can inspect your truck and check the heat controls to see if that is the primary reason for the heat not working. Many drivers in the Decatur, IL area have used our top-rated company for their semi-truck repair services.

Damaged Coolant Hoses

If the heat in your truck is not working, you should start by checking your coolant hose to see if you detect a leak or if it looks damaged. When your semi-truck begins to get older, the coolant hose can start to become clogged or worn. If you notice any damage or deterioration to the coolant hose, you will need to replace it so that you don’t have to worry about being stuck in a cold truck with no heat during the winter.

Issues With Heater Core

The heater core is one of the most important parts of your semi-truck heating system. This can easily get clogged by debris and sludge. Once the heater core gets clogged, the heat flow in your truck starts to decrease. Over time, the heater core can become old and weak and struggle to warm your truck. When you contact Decatur Trailer Sales & Service, Inc. by calling 217.422.7179, we will assist you with your semi-truck repair and maintenance to detect any problems and repairs your truck’s heater core might need.
