RADIATOR REPAIR
Radiator Repair Services:
- Thorough inspection of radiator for leaks, corrosion, or damage that may compromise cooling efficiency.
- Pressure testing of the radiator to identify any weak spots or areas prone to leaks.
- Flushing and cleaning of the radiator to remove buildup of sediment, rust, or other contaminants.
- Replacement of radiator hoses and clamps to prevent coolant leaks and ensure proper coolant flow.
- Inspection and repair of radiator fins for damage or blockages that may obstruct airflow.
- Repair or replacement of radiator tanks, cores, or seals to address leaks or structural issues.
- Testing and replacement of radiator cap to ensure proper sealing and pressure regulation.
- Installation of high-quality radiator coolant to maintain proper engine temperature and prevent corrosion.
- Inspection and repair of radiator mounts and brackets to ensure secure attachment to the vehicle.
On a heavy-duty diesel semi truck, the cooling system isn't just keeping your engine comfortable, it's actively managing the enormous heat output of a high-displacement diesel engine running under load, hour after hour, mile after mile. A diesel engine that can't shed heat efficiently will damage itself quickly and expensively. Cylinder head damage, blown gaskets, warped components, and catastrophic engine failure are all downstream consequences of a cooling system that isn't doing its job. At Rolling Smoke Diesel Repair, we offer comprehensive radiator and cooling system services built for the thermal demands of commercial diesel trucks.
Our Heavy-Duty Radiator and Cooling System Services
- Radiator Inspection and Repair: Heavy-duty truck radiators take a beating — road debris, vibration, corrosion, and years of thermal cycling all take their toll. We inspect radiators for leaks, core damage, fin damage, and tank integrity, and repair what can be repaired correctly. A properly repaired radiator is often a cost-effective alternative to replacement, and we'll always give you an honest assessment of which route makes more sense for your situation.
- Radiator Replacement: When a radiator is beyond serviceable repair, cracked tanks, severe core damage, or compromised seals, we replace it with a heavy-duty unit built to handle the cooling demands of your specific engine and application. We don't cut corners with undersized or light-duty substitutes on a commercial truck.
- Coolant System Flush and Service: Diesel engine coolant degrades over time, losing its corrosion inhibitors and becoming acidic, actively attacking the metal surfaces it's supposed to protect. A coolant flush removes degraded fluid, scale buildup, and contaminants, and replaces it with fresh coolant at the correct concentration and DCA (Diesel Coolant Additive) level. This is one of the most important and most overlooked maintenance items on a diesel truck.
- DCA (Diesel Coolant Additive) Testing and Treatment: Diesel engines are susceptible to cavitation erosion on cylinder liner walls, caused by pressure waves in the coolant. Proper DCA levels in the coolant protect against this damage. We test DCA concentration and treat the system to bring it back to the correct level, a simple service that can prevent extremely costly liner and block damage.
- Coolant Pressure Testing:
Pressure testing the cooling system allows us to identify leaks that may not be visible externally — including slow seeps at hose connections, radiator tanks, and water pump seals, as well as internal leaks at head gaskets that allow combustion gases into the coolant circuit. Finding these early prevents a minor issue from becoming a major engine repair.
Warning Signs Your Cooling System Needs Attention
- Engine temperature running higher than normal or climbing under load
- Overheating events or temperature gauge spiking
- Sweet smell from the engine compartment or exhaust, a sign of coolant burning or leaking
- Visible coolant puddles under the truck after it's been parked
- Coolant level repeatedly dropping with no obvious external leak
- White or gray smoke from the exhaust, can indicate coolant entering the combustion chamber
- Heater output dropping, often an early sign of coolant circulation issues
Protect Your Engine Investment
The cost of proper cooling system maintenance is a fraction of what an overheating-related engine failure costs. At Rolling Smoke Diesel Repair, we take cooling system health seriously because we've seen what happens when it's neglected. Whether you need a routine coolant flush, a pressure test, a water pump replacement, or a full radiator swap, our team has the expertise and equipment to handle it correctly. Contact us today to schedule your cooling system service.
