Why coolant ages out
The corrosion inhibitors in coolant deplete with time and heat. Once they are spent, aluminum heads and radiators begin to corrode. Atlanta heat and stop-and-go miles age the mix faster than highway driving.
Staying on the interval is inexpensive protection for the water pump, radiator, and heater core.
What a typical shop charges
A conventional shop flush often lands between $100 and $200, which usually includes their coolant.
You buy the exact spec your engine calls for, since Honda, Toyota, Ford, and BMW formulas differ regardless of color. We perform the exchange for a flat labor fee.
How a Road Wrencher flush visit works
We need a level driveway, an engine cool enough to open the system safely, and the correct coolant on hand.
- Step 1: We diagnose it. Color, leaks, oil in the overflow tank, and whether a thermostat or radiator should be addressed first.
- Step 2: The exact shopping list. Coolant type, concentration, quantity, and distilled water if we are mixing it.
- Step 3: Flat-rate flush. Drain, refill, bleed the air, and confirm the temperature holds in range.
