Cooling System Repair

Keep Your Engine Running Cool

Overheating is more than an inconvenience — continued driving with a cooling-system problem can lead to serious and expensive engine damage.

At Zavagli Auto LLC, we diagnose and repair cooling-system problems on cars, trucks, SUVs, and diesel vehicles. Whether you need a quick mobile repair or a more involved repair at our shop, we use professional diagnostics to identify the actual cause of the problem — not just replace parts and hope it fixes it.

Cooling System Diagnostics

A cooling-system problem isn't always as simple as a bad thermostat or low coolant. Electrical problems, cooling fans, sensors, wiring, water pumps, restrictions, and other issues can cause similar symptoms.

Our diagnostic process can include:

• Cooling system pressure testing

• Overheating diagnosis

• Coolant leak diagnosis

• Cooling fan testing

• Thermostat operation testing

• Water pump diagnosis

• Temperature sensor testing

• Radiator inspection

• Coolant flow testing

• Electrical and wiring diagnosis

• Cooling system warning light diagnosis

• Engine temperature monitoring

• Cooling system performance testing

Cooling System Repairs

Depending on the vehicle and diagnosis, we can repair or replace components including:

Radiators
Repair or replacement of damaged, leaking, restricted, or failing radiators.

Water Pumps
Diagnosis and replacement of mechanical or electric water pumps when required.

Thermostats
Replacement of thermostats that are stuck open, stuck closed, or operating incorrectly.

Cooling Fans & Fan Controls
Diagnosis and repair of electric cooling fans, fan modules, relays, wiring, and related controls.

Coolant Leaks
Finding the source of coolant loss instead of simply topping off the reservoir.

Hoses & Cooling Components
Replacement of damaged, leaking, swollen, cracked, or failed cooling-system components.

Temperature Sensors & Electrical Issues
Diagnosis of inaccurate temperature readings, warning messages, wiring problems, and sensor-related faults.

Overheating? Don't Keep Driving It.

If your temperature gauge is climbing, you're getting an overheating warning, or you're repeatedly losing coolant, continuing to drive can turn a repairable cooling-system problem into major engine damage.

If your vehicle is overheating, shut it down and let it cool before continuing to drive.

Zavagli Auto can help determine whether the problem is caused by a coolant leak, thermostat, water pump, radiator, cooling fan, electrical issue, sensor, or another underlying problem.

Mobile When Possible. Shop When Necessary.

Some cooling-system repairs can be handled right where your vehicle sits. Others require additional equipment, extended diagnostics, or more involved repairs.

That's why Zavagli Auto offers both mobile and shop repair services.

Mobile Service
Convenient diagnosis and repairs at your location when the repair can safely be performed on-site.

Shop Service
For larger repairs, extended diagnostics, cooling-system component replacement, and jobs requiring additional equipment.

We Diagnose the Problem — Not Just the Symptom

An overheating vehicle may have several symptoms at once. Our goal is to determine why the vehicle is overheating or losing coolant before recommending repairs.

From electrical diagnostics to mechanical cooling-system testing, we approach the problem from both sides to help avoid unnecessary parts replacement.

Need Cooling System Repair?

Whether your vehicle is overheating, losing coolant, showing a temperature warning, or simply isn't maintaining the correct operating temperature, we're ready to help.
