No matter what time of year, whether stuck in traffic in the winter or road-tripping in the summer, your cooling system is working hard to keep your engine cool. That said, if the temperature gauge creeps up or you spot a coolant puddle under the car, it’s time to think about radiator repair in Santa Clarita. Here’s a clear look at how radiators work, the signs something’s wrong, and why a mobile radiator repair with AutoNation Mobile Service is the easiest way to get your engine temperatures under control.
How a Radiator Works
Your engine creates heat, a lot of heat. Coolant (antifreeze) absorbs that heat and carries it to the radiator. As air passes through the radiator’s fins, often assisted electric fans, the heat is released to the outside air. A thermostat regulates when the coolant flows, the radiator cap maintains system pressure to raise the boiling point, and an overflow tank captures any fluids that may leak out. When everything is sealed, pressurized, and flowing correctly, you get stable temperatures, strong heater performance in winter, and longer engine life.
Symptoms of a Failing Radiator
Watch for these red flags to determine if radiator repair is needed:
• Temperature gauge spikes or fluctuates
• Steam from the grille or hood
• Visible coolant leaks or crusty, colored residue around the radiator, cap, or hoses
• Low coolant level that keeps dropping after you top off
• Heater blowing lukewarm air in winter
• Discolored, rusty, or sludgy coolant in the reservoir
• Cooling fans not engaging or running constantly
• Check engine light for overheating or related sensor faults
Why Radiator Repair is So Important
Cooling issues escalate quickly. Overheating can warp cylinder heads, damage gaskets, and lead to expensive repairs. A clogged radiator, sticking thermostat, weak water pump, cracked tank, or failing cap reduces heat transfer and pressure control, pushing the system past its limits. Catching problems early keeps repairs simpler and protects your engine.
