Semi truck engine overheating poses some very real and serious risks to your safety and the safety of those around you. If your truck’s engine is overheating, take it to a mechanic or call mobile truck repair immediately, rather than driving it home or taking it on the road while under duress. Here are five reasons why your semi truck engine is overheating that you need to know about.
1) Thermostat Failure
Many truck drivers don’t know that if their engine is overheating, one of the first things they should check is to make sure the air conditioner and heater in the cab are working. A possible cause of overheating is a bad thermostat. When a thermostat fails, it can stop cooling the motor when it’s needed most, leading to overheating. This usually results in an illuminated check engine light or a warning message on your dashboard display such as engine too hot.
2) Dirty Cooling System Components
Many of the parts on your truck engine’s cooling system may get dirty over time, creating more heat and less efficiency. A clogged radiator may not allow air to flow through it, increasing the temperature of the coolant and reducing engine performance. Other problems that can arise are dirty or faulty water pump, thermostat and fan belt. Some newer semi trucks have aluminum radiators; these components will need to be inspected regularly because aluminum is softer than traditional steel metals and is more prone to erosion.
3) Worn out Cooling System
The antifreeze’s main function is to keep your engine from freezing in cold climates and from overheating in hot climates. It is possible that there is a leak in the radiator or that your coolant level is too low and needs to be replenished. Low coolant levels may lead to other problems, including warped or cracked hoses and head gaskets that have failed due to heat. If the problem persists, you will need professional assistance in order to avoid damaging your engine even more severely.
4. Failed Belt System
A failed belt system can cause your truck engine to overheat. This happens when the serpentine or timing belt that drives various components of your engine breaks and becomes wrapped around other vital engine parts, such as the alternator. You may notice a burning smell or the audible screeching of belts coming from one side of the truck only if this is the issue. You might also experience rapid acceleration and delayed braking if you’re driving downhill with your engine improperly aligned. If you’re overheating frequently, try using one hand to feel for loose belts by taking off any covers that might obstruct you from doing so.
5) Exhaust Leaks
Exhaust leaks can be a major cause for engine overheating and loss of power. You should keep an eye on your exhaust pipe for any sign of leaking. A broken or cracked exhaust manifold will also cause the motor to overheat because it restricts the flow of exhaust gases from escaping. Heavy duty exhaust gaskets are available at most auto parts stores to repair minor leaks, but if you have a large leak that’s still not fixed, you’ll need to replace the muffler assembly or exhaust pipe. If your vehicle’s vibration becomes more pronounced when the brakes are applied, it could mean that the brake shoes have worn down too far and are rubbing against their metal plates. Replacement may be needed if replacement parts are not available locally.
