Cooling System FAQ
Answers about overheating, coolant, and radiator repairs.
Why is my car overheating?
Common causes include coolant leaks, a failed thermostat, water pump issues, clogged radiator, or cooling fan problems. We test the system to confirm the cause.
Can I drive with a coolant leak?
It’s risky. Low coolant can cause overheating quickly and lead to engine damage. It’s best to have it inspected ASAP.
How often should coolant be changed?
Intervals vary by vehicle and coolant type, but many benefit from service every 3–5 years. We’ll recommend the right schedule for your car.
Do you replace water pumps and thermostats?
Yes. We replace and verify operation to ensure proper temperature control.
What if the overheating only happens in traffic?
That often points to cooling fan, airflow, or radiator efficiency issues. We can diagnose those conditions.
