Radiator Repair & Coolant Flush in Sun Valley & Glendale, CA

Radiator Repair & Coolant Flush in Sun Valley

Your radiator is the front line of defense against engine overheating. It dissipates the heat that coolant absorbs from the engine, keeping everything at a safe operating temperature. In the San Fernando Valley, where summer temperatures regularly exceed 100°F, a failing radiator means a tow truck and a potentially damaged engine.

At A Plus Auto Shop, we handle everything from minor coolant leaks and radiator cap replacements to complete radiator replacements and full cooling system flushes. We pressure-test the system to find leaks, check the radiator for internal blockages, and make sure your cooling system can handle the worst Valley heat.

What We Offer

Our Radiator Repair & Coolant Flush Services

Comprehensive radiator repair & coolant flush services for all makes and models at A Plus Auto Shop.

Radiator Replacement

Cracked tanks, corroded cores, and internal blockages can all require radiator replacement. We install quality radiators matched to your vehicle's specifications and pressure-test the system to verify a leak-free installation.

Coolant Flush & Fill

Over time, coolant breaks down and loses its ability to protect against corrosion, freezing, and overheating. We perform a complete flush to remove old coolant, rust, and sediment, then refill with fresh coolant that meets your vehicle's requirements.

Radiator Leak Repair

Small leaks at radiator tanks, hose connections, or the core can often be identified with a pressure test. Depending on the location and severity, we may be able to repair the leak or recommend replacement for a permanent fix.

Radiator Fan Diagnosis & Repair

Electric radiator fans pull air through the radiator when the vehicle is stopped or moving slowly. A failed fan motor, bad relay, or faulty temperature sensor can prevent the fan from running, causing overheating in traffic or at idle.

Radiator Hose Replacement

Soft, swollen, or cracked radiator hoses can burst without warning, causing rapid coolant loss. We inspect upper and lower radiator hoses and replace them when they show signs of age or deterioration.

Cooling System Pressure Test

A pressure test is the most reliable way to find coolant leaks. We pressurize the system and inspect all components — radiator, hoses, water pump, heater core, and gaskets — to locate even the smallest leak.

Common Questions

Frequently Asked Questions

Answers to common questions about radiator repair & coolant flush at A Plus Auto Shop.

How do I know if my radiator is bad?

Signs include coolant leaking under the car (usually green, orange, or pink fluid), engine overheating, coolant level dropping frequently, discolored or rusty coolant, or visible damage to the radiator. Steam from under the hood is a sign of a significant leak.

How often should I get a coolant flush?

Most manufacturers recommend a coolant flush every 30,000 to 50,000 miles or every 3-5 years. However, if your coolant appears rusty, dark, or has debris in it, a flush may be needed sooner. Check your owner's manual for your vehicle's specific interval.

How much does radiator replacement cost?

Radiator replacement cost varies by vehicle. Some vehicles have easy-to-access radiators while others require removing additional components. We provide upfront estimates before starting work. Call (818) 500-1939 for a quote.

Can I just add water instead of coolant?

Water alone doesn't provide the corrosion protection, boiling point increase, or freezing protection that coolant provides. In an emergency, water can be used temporarily, but the system should be flushed and filled with the proper coolant mixture as soon as possible.
