Why Coolant System Health is Essential

The Role of Coolant in Diesel Engines

A diesel engine's coolant system maintains optimal operating temperatures and prevents overheating. The coolant, a mixture of water and antifreeze, circulates through the engine and absorbs heat. It then passes through the radiator, releasing this heat into the atmosphere. This process is essential for protecting engine components from damage due to excessive heat.

Common Coolant System Issues

Over time, coolant systems can develop leaks, clogs, or corrosion. These issues may lead to inefficient cooling, overheating, and potential engine damage. Regular maintenance and prompt repair are crucial in preventing these problems and ensuring the longevity of your diesel engine.

Our Coolant System Services

At Harmon Truck Service, our expert technicians are skilled in diagnosing and repairing a range of coolant system issues. Our services include:

  • Coolant Flush and Replacement: We remove old coolant, flush the system to eliminate debris or corrosion, and replenish it with high-quality coolant suitable for your specific diesel engine.
  • Leak Detection and Repair: Using advanced diagnostic tools, we identify and fix leaks in the coolant system, ensuring no coolant is lost and the system remains efficient.
  • Radiator Repair and Maintenance: We inspect and repair radiators, addressing any damages or blockages that could hinder the cooling process.
  • Hose and Pump Inspection: Regular checks of hoses and the water pump are critical for preventing leaks and ensuring effective coolant circulation.

Preventive Maintenance: Key to Longevity

Regular Check-Ups

Scheduling regular coolant system check-ups is essential for early detection of potential issues. We recommend a complete coolant system inspection at least once a year or according to your manufacturer's guidelines.
