Heavy Duty Truck Radiator Repair: What Is Cooling System Repair?

Semi truck in need of radiator repairs

Your heavy-duty truck engine starts operating at extraordinarily high temperatures within seconds of turning it on. If these temperatures were allowed to get too high, the engine would overheat and risk melting. Keep your eyes peeled for these significant indicators of the cooling system and radiator issues while you're behind the wheel to avoid overheating on the side of the road and incurring a hefty repair cost.

White smoke 

If your cooling system is malfunctioning, one of the first signs is white smoke emanating from your truck. You might notice it coming from beneath the hood or from the exhaust in big puffs. If you see smoke coming from beneath the hood, pull over immediately and turn off your truck, since this is a warning that your truck is overheating. White smoke rising from the tailpipe might suggest an internal coolant leak, enabling coolant to be burned up in the engine and then expelled via the exhaust system. This will almost surely result in overheating since your truck will no longer have enough radiator fluid to maintain proper operating temperatures.

Temperature gauge is increasing 

When driving your truck, one of the most apparent signs of danger is directly in front of you, on your dashboard. If the cooling system fails to control the engine temperature, the temperature indicator on display will increase to the red zone.

Discoloration under the hood 

Rust, or at the very least missing paint, will be a more subtle symptom of problems. If the cooling system line springs an interior leak it can often result in the coolant fluid being splashed onto hot engine components. The coolant will boil away quickly, removing any paint and leaving the patches to corrode.

Low coolant levels

Regular maintenance on your truck in your driveway, including checking your coolant level, should be done to ensure everything is in excellent operating condition. If the coolant level in your truck is low, it might be due to a leak within the system that allows it to be burned up, putting your truck in danger of overheating. Make sure you inspect your truck's engine while it's cold!

Visible coolant leak 

You have a coolant leak if you observe a brilliant green, sweet-smelling fluid gathering in your driveway or see it oozing from your truck. You should go to the truck repair shop as soon as possible to avoid any more harm.

How to fix heavy-duty truck radiator issues? 

The radiator is a critical component in any tractor or truck that helps keep the engine cool. The radiator removes heat from the engine by circulating coolant via a series of coils. To keep the engine from overheating, the cooled air is pumped back into it.

If your radiator leaks, coolant is lost, and your truck's engine is at risk of overheating and breaking down. "Can I still drive my truck for a short time if I have a radiator leak?" is one of the most frequent queries technicians receive about radiator leaks. "No!" is the short response.

When you believe or know you have a radiator leak, you should first call specialists for professional radiator servicing. Operating a truck with a leaking radiator can result in severe and costly engine damage. And when we say serious harm, we mean it. A skilled technician may be able to plug the area depending on the severity of the radiator leak, or it may be necessary to replace it. In any event, if you have a radiator leak, you should not drive too far.

The leak might cause additional engine damage, necessitating a far more comprehensive and expensive repair. If you drive with a radiator leak, your engine will overheat, which may lead to a slew of additional issues.

What Should You Do If Your Truck Gets Too Hot?

So, what happens if you don't realize you have a radiator leak, and your engine overheats as a consequence while driving? Turn up the heat on your heater to the maximum setting! This is undoubtedly paradoxical and may be particularly aggravating on a hot day. It does, however, take some of the heat burden off the engine, which may help decrease damage.

If the temperature gauge on your engine does not decrease after this, pull over to a safe spot in your truck as soon as possible. To allow the heat out of your truck:

  1. Open the hood, but not the radiator cap, as you might burn yourself.
  2. Request a tow truck or roadside help, and then call one of our experts immediately to have your truck's overheating issue investigated since a radiator leak is most likely to blame.
  3. Get the help of a professional heavy-duty truck repair company.
