How Do I Detect Where A Coolant Leak Is Coming From?

Coolant leaks are often indicated by puddles of brightly colored fluid under the vehicle or steam coming from under the hood. You might also notice a sweet smell, or your temperature gauge climbing rapidly. Trained technicians can perform a pressure test or use UV dye and detection tools to find the source of the leak accurately.

Why Is My Engine Overheating But The Coolant Is Full?

Your coolant may be full, but if your engine is still overheating, there could be circulation problems or a component failure. A stuck thermostat, malfunctioning fan clutch, or clogged radiator can all prevent proper heat dissipation. In some cases, air pockets in the cooling system can block flow and lead to overheating despite having coolant present.
