How We Diagnose and Repair It On Site

Every Old Hickory job follows the same testing order, so the diagnosis is based on readings rather than guesses:

  1. 1Cooling-system pressure test to locate the leak instead of guessing at it
  2. 2Radiator cap pressure-holding test
  3. 3Thermostat operation check — stuck closed is a classic cause of fast overheating
  4. 4Water-pump weep-hole and bearing-play inspection
  5. 5Electric fan and fan-relay operation test
  6. 6Hose, clamp, radiator-core, and heater-core-line inspection, then a proper bleed of trapped air after the repair

How long the job takes

Hoses and thermostats are usually done inside 90 minutes. Water pumps and radiators run two to four hours depending on how much has to come off first.

Parts and warranty

Manufacturer-spec coolant and quality replacement parts. Mixing coolant types is a real cause of repeat failures, so we don't take shortcuts there.

What you'll pay

Nothing gets replaced before it's confirmed. We test first, show you the reading, then give a flat price for the repair.

Thermostat Replacement in Old Hickory — FAQs

My car overheated once and seems fine now. Is it fine?

Usually not. A one-off overheat is normally a stuck thermostat, a dying fan, or a slow leak that's already draining again. Any of the three will repeat, and repeat overheating is what warps a head gasket.

Can I just keep topping up the coolant?

Topping up hides the leak while air pockets keep forming. Air pockets cause hot spots, and hot spots are what cause expensive engine damage. Pressure-testing the system finds the leak in minutes.

Do you work on an overheated car where it sits?

Yes — that's the point of the mobile service. Don't drive an overheating vehicle across Old Hickory looking for a shop; let it cool and we'll come to it.

Do I need to bring my car anywhere for cooling system work in Old Hickory?

No. This is a mobile service — we drive to your address in Old Hickory with the tools, the tester, and the replacement part. Driveway, apartment lot, office parking, or a roadside shoulder all work as long as the vehicle is on reasonably level ground and we can get a van beside it.
