Cooling System Repair Services in Hutto, TX.

Overheating almost always traces back to one of a few causes: low coolant from a leak, a thermostat stuck closed, a worn water pump that's no longer circulating fluid, a clogged or restricted radiator, or a failed electric cooling fan. We start with a pressure test of the cooling system, an infrared scan of radiator temperature, and a verification of fan operation, which narrows the cause within the first thirty minutes. Continuing to drive an overheating engine risks warping the cylinder head and blowing the head gasket, so it's worth stopping and getting it diagnosed promptly.

A typical radiator replacement on a car or small SUV runs $400–$900 with parts, labor, and a fresh coolant fill included. Larger trucks, vehicles with integrated transmission coolers, and European cars with plastic-tank assemblies can run higher because of part cost and the labor to remove front-end components. We always quote the job in writing after inspection so you can see exactly what's included before authorizing work.

Most manufacturers call for coolant replacement every 30,000–50,000 miles, though some long-life formulations stretch to 100,000 miles on the first interval. Rather than guess from mileage alone, we test the coolant's pH balance and freeze/boil protection with a refractometer, which tells us whether the corrosion inhibitors are still active. Spent coolant becomes mildly acidic and eats away at aluminum heater cores, water pumps, and radiators — repairs that cost far more than periodic fluid service.
