Cooling System & Radiator Repair in Longmont, CO

Protect Your Engine From Overheating Problems

If your temperature gauge is climbing, you see steam from under the hood, or notice bright green or orange fluid on the ground, your cooling system may be in trouble. Ignoring radiator problems can lead to serious engine damage and unexpected breakdowns. At Christian Brothers Automotive Firestone Blvd, we provide thorough radiator repair to help keep your vehicle safe and reliable.

We know how stressful it feels when your only vehicle starts to overheat or leak coolant. You rely on it to get to work, take kids to school, and handle everyday errands here in the area. Our goal is to take the confusion out of cooling system issues so you can make confident decisions about your car.

Our ASE-certified technicians inspect your radiator and entire cooling system, explain what we find in plain language, and only move forward with work you approve. Guided by our principle to love our neighbors, we focus on honesty, integrity, and clear communication from the moment you arrive.

Signs Your Radiator Needs Attention

Most drivers first notice cooling system trouble when something feels off during normal trips in and around Longmont. You might see the temperature gauge creeping higher than usual on the way up a hill, or spot a small puddle where you usually park. These early warnings are important for protecting your engine.

Your radiator and cooling system work together to move heat away from the engine so it can operate at a safe temperature. When coolant cannot circulate properly or leaks out, metal parts can warp or crack from excessive heat. Catching these issues early often means simpler radiator service instead of larger repairs later.

Common signs your radiator may need attention include:

  • The temperature gauge is running higher than normal or entering the red zone
  • Steam or a hot smell coming from under the hood after driving
  • Bright green, orange, or pink fluid under the front of your vehicle
  • A sweet smell around the car may indicate a coolant leak
  • Low coolant level in the reservoir that keeps dropping
  • Heater not working well in cooler weather because the coolant flow is affected

Some of these symptoms can point to problems beyond the radiator, such as a thermostat, hoses, or water pump issue. When you bring your vehicle to us, we look at the entire cooling system instead of guessing at a single part. This careful approach helps us recommend the right combination of radiator service and repair for your situation.

Avoid the cost of major engine repairs by acting now. Schedule your spot online or call (303) 997-3685 to fix cooling issues before they escalate.

What To Do If Your Car Overheats

An overheating engine is stressful and dangerous, especially on the Front Range. Knowing how to react protects your engine and keeps you safe. If your temperature gauge spikes, treat it as an urgent warning to prevent severe damage.

If your car begins to overheat, follow these steps immediately:

  • Turn Heater: Blast the heater and turn off the AC to help move heat away from the engine block.
  • Pull Over: Signal immediately and steer your vehicle to a safe spot away from active traffic flow.
  • Stop Engine: Turn off the ignition and allow the engine to cool completely before attempting to open the hood.
  • Avoid Cap: Never open the radiator cap on a hot engine, as pressurized coolant causes severe burns.
  • Call Assistance: Contact roadside help if the vehicle refuses to cool down or you feel unsafe attempting repairs.

Once you are safe, contact our team to schedule a cooling system inspection. We help plan the next steps, arranging transportation or scheduling a visit. From the first call, we keep the process calm and straightforward for you.
