How Do You Detect Where A Coolant Leak Is Coming From?
Detecting a coolant leak usually involves both a visual inspection and a pressure test. Technicians check hoses, the radiator, and the water pump for residue or damp spots that reveal leaks. If the source is not immediately visible, specialized dye testing can be used to identify even the smallest leaks. This ensures the issue is found before it causes further engine damage.
What Are The Common Signs Of A Malfunctioning Cooling System?
A failing cooling system often shows itself through rising temperature gauges, poor cab heater performance, or visible coolant leaks. Some trucks may also show warning lights, while others may experience engine overheating during idle or uphill driving. These symptoms should never be ignored, as they can quickly lead to engine failure if left unresolved.
