Frequently Asked Questions
What are signs of a failing radiator?
Overheating engine, coolant puddles under the car (green, orange, or pink fluid), low coolant level, visible corrosion or damage on the radiator, coolant in the overflow tank turning brown/rusty, and steam from the hood.
How long do radiators last?
Most radiators last 8-15 years. Plastic/aluminum radiators (most modern cars) tend to fail at the plastic tanks first. All-aluminum racing radiators last longer. Regular coolant changes (every 30,000-50,000 miles) extend radiator life.

St. Louis's costs reflect local labor rates driven by the diversified economy, varied climate conditions that affect materials and scheduling, and moderate permitting requirements. The balanced labor market also influences competitive pricing.
