Radiator Repair FAQ

Common questions about radiator repair services.

How long does a typical radiator repair take? +
Most radiator repairs can be completed within 2-4 hours, depending on the extent of damage. Simple leak repairs may only take 1-2 hours. We'll provide a time estimate after diagnosing your specific issue.
Is radiator repair cheaper than replacement? +
Yes, in most cases. A repair might cost $150-300 compared to $350-600+ for a new radiator. However, if your radiator is old or has multiple issues, replacement may offer better long-term value with a warranty.
How do I know if my radiator can be repaired? +
Our technicians will perform a thorough inspection and pressure test. Generally, radiators with small pinhole leaks, minor tank damage, or corroded fittings are good candidates for repair. Radiators with extensive corrosion, multiple leaks, or damaged cores typically need replacement.
