Coolant Leak Diagnostics and Repair
Vehicle Diagnostics — Cheyenne, WY
A coolant leak never fixes itself — it either drips where you can see it or disappears somewhere worse, like into the engine. TDC Automotive inspects and tests the full cooling system: radiator, hoses, water pump, heater core, thermostat housing, and head gasket, to find exactly where the coolant is going.
Catching a cooling system problem early is the difference between replacing a hose and replacing an engine. If you're topping off the overflow tank, smelling antifreeze, or seeing the temperature gauge creep up, get it looked at before a hot day or a heavy load turns it into an overheating failure.
What's Included
- Cooling system pressure testing
- Radiator, hose, and water pump leaks
- Heater core and thermostat housing leaks
- Head gasket assessment on gas and diesel engines
- Stop small leaks before they become overheating failures
How Trevor Diagnoses a Problem
- Verify the complaint
Before touching a wrench, Trevor reproduces the symptom you're describing — sometimes on a test drive with you in the passenger seat so you can point out exactly what you're feeling or hearing.
- Inspect the vehicle
A visual and hands-on physical inspection often reveals what a scan tool can't: chafed wiring, soot trails, wet gaskets, loose components.
- Scan for trouble codes
Diagnostic trouble codes (DTCs) narrow the search to the right system and circuit.
- Test to confirm
The suspect component gets tested and confirmed as failed before it's replaced. Then the repair is verified with a final test drive.
