Coolant Leak Services
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 the most reliable long-term solution.
Hose & Clamp Leak Repair
Cracked, swollen, or loose hoses are among the most common leak sources. We replace failed hoses and worn clamps to seal the system and prevent the leak from returning with heat cycling and pressure.
Water Pump Seal & Gasket Repair
Water pumps commonly leak from the weep hole or gasket as they age. We replace leaking water pumps and their gaskets to stop coolant loss and restore proper circulation throughout your cooling system.
Heater Core Leak Repair
A leaking heater core causes a sweet smell inside your cabin, foggy windows, and wet carpet. We diagnose heater core leaks and replace failed units to eliminate coolant loss and restore proper cabin heat.
Gasket & Seal Leak Repair
Head gaskets, intake manifold gaskets, and other seals can develop leaks that allow coolant to escape externally or internally into your oil or cylinders. We diagnose and repair gasket leaks before they lead to serious engine damage.
