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

Always make sure that you check when topping up your coolant, because using the wrong type can lead to severe engine damage. It may cause corrosion, clogs, and inefficiency in heat dissipation, posing significant risks to your truck's engine and its overall health.

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.
