Signs Your Radiator Needs Repair
TL;DR: If you notice any of these warning signs, your cooling system needs professional attention immediately. Ignoring them risks expensive engine damage.
- Temperature gauge rising higher than normal or into the red zone
- Coolant puddles (green, orange, or pink fluid) under your vehicle
- Sweet, syrupy smell from the engine bay or inside the cabin
- Steam or white smoke coming from under the hood
- Discolored or rusty coolant visible in the overflow tank
- Needing to add coolant or water frequently between services
- Dashboard warning light for engine temperature illuminated
- Heater blowing cold air when it should be warm
Why Radiator Problems Are Urgent
Your radiator keeps your engine at a safe operating temperature. When it fails, the consequences can be severe and expensive:
- Warped cylinder heads from extreme overheating
- Blown head gasket allowing coolant into the engine oil
- Cracked engine block from thermal stress
- Complete engine seizure requiring full replacement
- Being stranded on the roadside in Sonoma County heat

Coolant Leak Diagnosis
Precision pressure testing to locate leaks in the radiator, hoses, water pump, heater core, and head gasket. We find the exact source — no guessing.
Radiator Repair
Professional repair for minor leaks, damaged tanks, and corroded connections. When repair is possible, we save you the cost of full replacement.
Radiator Replacement
Complete radiator replacement with OEM-quality or OEM parts. Includes new coolant, pressure testing, and system verification before delivery.
Coolant Flush & Fill
Full cooling system flush to remove rust, scale, and contaminated coolant. Refilled with fresh manufacturer-recommended coolant for optimal protection.
Hose & Thermostat Service
Inspection and replacement of radiator hoses, heater hoses, clamps, and thermostats. Worn hoses are the most common cause of roadside coolant leaks.

Understanding Your Vehicle's Cooling System
TL;DR: Your cooling system is a network of components working together to prevent engine overheating. A failure in any single part can compromise the entire system.
Modern engines generate extreme heat during operation — enough to warp metal and destroy internal components if not properly managed. Your cooling system circulates coolant through the engine block, absorbing heat and carrying it to the radiator where it is dissipated into the air. This continuous cycle keeps your engine within its optimal temperature range, typically between 195-220 degrees Fahrenheit.
The radiator is the primary heat exchanger in this system, but it works in concert with several other critical components: the water pump that circulates coolant, the thermostat that regulates flow, the cooling fans that pull air through the radiator, and a network of hoses connecting everything together. When any one component fails, the entire system is compromised.
Sonoma County's warm summers put extra stress on cooling systems. Temperatures regularly reach the 90s and 100s during summer, and stop-and-go traffic on Highway 101 through Santa Rosa and Rohnert Park reduces airflow through the radiator. This combination makes preventive coolant system maintenance especially important for local drivers.
If you are experiencing any cooling system symptoms — rising temperature gauge, coolant leaks, or sweet smell from the engine — do not delay service. A moderate cooling system repair today prevents a catastrophic engine failure tomorrow. Our diagnostic services pinpoint the exact issue quickly and accurately.

Radiator Repair FAQs
Common questions about radiator repair and cooling system service, answered by our ASE certified technicians.
How do I know if my radiator needs repair?
Signs include engine overheating, coolant leaks under the vehicle, a sweet smell from the engine bay, steam from the hood, or the temperature gauge running higher than normal. Our ASE certified technicians can diagnose the issue with a cooling system pressure test. Call (707) 584-7727 for a free inspection.
Can a radiator be repaired or does it need to be replaced?
Many radiator issues can be repaired, including small leaks, hose connections, and thermostat problems. However, severely corroded or cracked radiators typically need replacement. We always recommend the most cost-effective solution and explain your options before any work begins.
How long does radiator repair take?
Most radiator repairs are completed same-day. A coolant flush takes about an hour, while a full radiator replacement typically takes 2-4 hours depending on your vehicle. We keep you informed throughout the process.
What happens if I keep driving with a bad radiator?
Driving with a failing radiator risks severe engine damage from overheating. An overheated engine can warp the cylinder head, blow the head gasket, or seize completely — turning a moderate repair into a major expense. Address radiator problems promptly to protect your engine.
Do you service all vehicle makes and models for radiator repair?
Yes. Our ASE certified technicians repair radiators and cooling systems on all makes and models, including domestic (Ford, Chevy, GMC), Japanese (Toyota, Honda, Nissan, Subaru), European (BMW, Mercedes, VW), and Korean (Hyundai, Kia) vehicles.
How much does radiator repair cost near me?
Radiator repair costs vary depending on the type of repair needed, whether it is a minor leak fix, hose replacement, or full radiator replacement, as well as your vehicle make and model. We provide transparent, upfront estimates before any work begins. Call (707) 584-7727 for a free estimate.
What is included in a radiator flush service?
Our radiator flush service includes draining the old coolant, flushing the system to remove rust, scale, and sediment buildup, inspecting hoses and connections for leaks or wear, and refilling with fresh manufacturer-recommended coolant. This preventive maintenance helps extend the life of your cooling system.
How often should I have my cooling system serviced?
Most manufacturers recommend a coolant flush every 30,000 to 50,000 miles or every 3-5 years. However, if you notice any signs of cooling system problems — leaks, overheating, discolored coolant — have it inspected immediately. Regular maintenance prevents costly radiator failures.
Why is my car overheating but the coolant is full?
If your coolant is full but your engine is overheating, the problem could be a faulty thermostat, a clogged radiator core restricting coolant flow, a failing water pump, a broken cooling fan, or a blown head gasket. Professional diagnosis with a pressure test and thermal inspection identifies the exact cause. Call (707) 584-7727 to schedule a diagnosis.
Do you offer same-day radiator repair service?
Yes. We offer same-day radiator repair for most vehicles. Our shop is fully stocked with common radiator parts, hoses, thermostats, and coolant for fast turnaround. For emergency overheating situations, call (707) 584-7727 and we will prioritize getting your vehicle in as quickly as possible.
