Replacing the water pump on a 1998 Lincoln Town Car with the 4.6L V8 typically requires 2–3 hours of labor. At independent shop rates ($80–$150/hr), labor costs range from $160 to $450. Dealerships may charge more ($150–$200/hr). Some shops quote a flat rate. The job involves removing the fan, shroud, belts, and timing chain cover components. Always get a written estimate. Parts (pump, gasket, coolant) add $50–$150.
