Winter is here, and your drivers rely on their truck’s heating system to keep them warm and comfortable. If the heat kicks out, it means a long trip in a freezing cabin. Here are some troubleshooting tips to help you find out what’s wrong with your truck’s heat.
Low Coolant
The heating system uses the same coolant as your air conditioner, except it heats it instead of cooling it down. When you drive the truck, it warms the engine. The engine heats the coolant, and the heating and cooling system circulates it through the radiator to moderate the temperature. When you turn on the heat, it pushes the warm coolant through the heater core inside the dash. Then hot air blows through the vents.
The truck’s heating system has nothing to send to the heater core without enough coolant. Often, it is an easy fix! Just fill up your engine coolant.
Keep an eye on fluid levels every time you stop. If it keeps going down, there is likely a leak, and you will need semi-truck repair. Leaks can occur anywhere in the system, including water pumps, hoses, and even radiators. Do not ignore the leak and bring it into Motorplex in Spokane or Auburn for repair.
Worn Heater Core and Coolant Hoses
Things wear out and can get dirty over time. The same goes for your heater core. The coolant runs through tiny passageways, and debris can cause a clog or rust over the years. A clog prevents the coolant from getting through, and you won’t get heat. Sometimes you can flush the heater core but invest in a replacement if that doesn’t work.
Hoses can also wear out, clog, or clamps can loosen. The coolant hoses should be the first to check if you suspect a leak. If they look worn out, replace them. This preventative maintenance can prevent a cold and uncomfortable drive in the future!
Heat Controls Aren’t Working
Sometimes your truck’s heating system can malfunction due to broken heat controls. These buttons and knobs have gotten a lot of use over the years and can eventually wear out. If none of these other issues seem to be the problem, it could be a control issue. Bring your truck in for semi-truck repair and have those controls fixed or replaced.
