How Do You Detect Where a Coolant Leak Is Coming From?

To detect a coolant leak in heavy-duty diesel vehicles, inspect hoses, the radiator, the water pump, and connections for visible drips or stains. Use a pressure tester to pressurize the system and check for leaks. UV dye and a blacklight can also help locate hard-to-see leak sources.

Can I Still Drive With a Coolant Problem?

Driving a heavy-duty diesel vehicle with a coolant problem is risky and not recommended. Coolant issues can lead to engine overheating, causing severe damage. If coolant levels are low or a leak is suspected, it's best to stop, inspect, and address the issue before continuing.
