Leak Source Diagnosis

Finding a coolant leak is detective work. We use cooling system pressure testing, UV dye detection, and careful visual inspection to pinpoint exactly where your coolant is escaping, whether from a hose, gasket, component, or hidden internal leak.

Radiator Leak Repair

Radiators develop leaks from corrosion, road debris damage, or failed seams. We locate the leak point and repair minor damage when possible, or replace the radiator with a quality unit when repair is not practical.
