Oil and Coolant Leaks

Precise leak diagnosis for gaskets, seals, and fittings — fixed at the source.

Oil and Coolant Leaks at 3A Garage

Oil and coolant leaks are one of the most common issues on higher-mileage European engines, and also one of the easiest to misdiagnose. A leak that looks like it's coming from one area often originates somewhere else entirely.

We use UV dye, smoke testing, and a careful visual and lift inspection to trace leaks back to their actual source — whether that’s a valve cover gasket, oil pan seal, water pump, or a cracked coolant expansion tank — rather than replacing parts by guesswork.

Left unaddressed, oil and coolant leaks can lead to overheating, seized components, or serious engine damage, so we always explain the severity and urgency clearly before recommending a repair.
