Truck Coolant System Repair Services in Hudson, NH

The Importance of Coolant System Maintenance for Diesel Trucks

The coolant system in a diesel truck is responsible for regulating the engine's temperature and preventing it from overheating. It comprises several components, including the radiator, water pump, thermostat, hoses, and coolant, that work together to ensure the engine stays within its optimal temperature range.

Regular maintenance of the coolant system is critical to ensure it functions correctly and efficiently. Neglecting it can result in coolant leaks, corrosion, and buildup of deposits that can cause blockages, ultimately leading to engine overheating, and in some cases, catastrophic failure.

Coolant System Maintenance Services Offered by Redmond Fleet

At Redmond Fleet, we offer a range of coolant system maintenance services, including

  • Coolant Flush and Refill: Over time, the coolant in the system can become contaminated with rust, scale, and other debris, reducing its effectiveness. 
  • Water Pump Inspection and Repair: The water pump is responsible for circulating the coolant through the engine. Over time, the bearings can wear out, leading to leaks and reduced performance. Our technicians will inspect the water pump for signs of wear and replace it if necessary.
  • Thermostat Inspection and Replacement: The thermostat regulates the engine's temperature by controlling the flow of coolant. A faulty thermostat can cause the engine to overheat or run too cold, affecting its performance. Our technicians will inspect the thermostat for proper operation and replace it if necessary.
  • Hose Inspection and Replacement: The hoses in the coolant system can become brittle and crack over time, leading to leaks and reduced efficiency. Our technicians will inspect the hoses for damage and replace them as necessary.
  • Coolant Pressure Test: A coolant pressure test is an effective way to identify leaks in the system. Our technicians will pressurize the system and check for leaks, allowing us to identify and repair them before they cause significant damage.

Benefits of Regular Coolant System Maintenance

Keeping on top of consistent regular maintenance of your truck or fleet vehicle’s coolant system offers several benefits, including

  • Improved Engine Performance: A well-maintained coolant system ensures that the engine operates at its optimal temperature range consistently, improving performance and fuel efficiency.
  • Extended Engine Life: Regular maintenance of the coolant system can help prevent damage to the engine, resulting in extended engine life.
  • Reduced Repair Costs: Neglecting the coolant system can result in costly repairs, including engine replacement. Regular maintenance helps prevent major repairs, reducing overall costs.

Redmond Fleet did an absolutely amazing  job on my truck! I went to them with a pretty large task- an entire frame swap on a truck. They were ready to take it on without any hesitation, and delivered nothing short of excellence! Matt and his crew were thorough about the entire job, making sure that any other problems / issues found along the way (warn out parts, etc.) were addressed and properly corrected. Matt was also good about keeping me up to date on what was going on throughout the job. Overall very satisfied with the end result! These guys know their stuff and aren’t afraid of a challenge.
