What Happens if You Put the Wrong Coolant in Your Truck?

Our Coolant System Repair Process
When you bring your vehicle into Hex 6 Diesel Services for coolant system repairs, you'll experience repairs like no other. We pride ourselves on a systematic approach to diagnosing and repairing these essential systems:
Initial Diagnosis: Our expert mechanics begin by thoroughly examining the coolant system to identify any leaks, corrosion, or damage. This includes checking the radiator, hoses, and connections.
Pressure Testing: We conduct a pressure test to ensure the system can maintain the appropriate pressure levels, which is vital for optimal engine temperature regulation.
Coolant Flush and Replacement: A complete coolant flush is performed to remove old, contaminated coolant. We then replace it with a high-quality coolant appropriate for your vehicle, ensuring better performance and longevity.
Radiator and Thermostat Inspection: Our team inspects and, if necessary, repairs or replaces the radiator and thermostat. These components are crucial for maintaining the correct operating temperature.
Final Testing: After repairs, we conduct a series of tests to ensure the coolant system functions correctly under various operating conditions.
Preventive Maintenance Advice: We also provide guidance on preventive maintenance to help you avoid future coolant system issues.
