Hyundai Radiator Repair in Gainesville, GA
From $150 · 2–4 hours · 12-month / 12,000-mile warranty
Radiator repair at Mr Automotive Repair in Gainesville, GA typically runs between $150 and $600 depending on whether we're patching a minor leak, replacing a cracked tank, or doing a full radiator swap. I'm Carlos Rivera, and I've been diagnosing cooling system failures long enough to know that what looks like a simple overheating problem is almost always a radiator issue that's been quietly getting worse for weeks. Georgia's summer heat puts a brutal load on cooling systems that were already marginal, and I've seen engines suffer serious internal damage because a $200 radiator job got put off too long. If your temperature gauge is climbing or you're spotting coolant on the ground, come see us at 2035 Memorial Park Dr before a small repair turns into an engine replacement.
- Radiator repair costs $150–$600 with same-day service in most cases.
- All work backed by a 12-month / 12,000-mile warranty.
- Georgia heat accelerates radiator failure—don't ignore early warning signs.
What's Included
- Full visual and pressure test of the radiator, hoses, and coolant reservoir
- Cooling system leak detection using dye or pressure gauge as needed
- Radiator removal and replacement or targeted repair of damaged tanks and seams
- Coolant drain, flush, and refill with manufacturer-specified fluid and mix ratio
- Thermostat inspection and replacement if found to be faulty during service
- Upper and lower radiator hose inspection with replacement recommended if cracked or soft
- Cooling fan operation check, including electric fan relay and shroud clearance
- Post-repair pressure test and road-temperature verification before vehicle return
Signs Your Radiator Needs Attention
- ⚠ Temperature gauge rises toward the red zone during normal driving or at idle
- ⚠ Sweet-smelling puddles or stains under the front of the vehicle after it sits
- ⚠ Coolant level in the reservoir drops repeatedly even though you keep topping it off
- ⚠ Visible discoloration, rust streaks, or crusty white buildup on the radiator fins or tanks
- ⚠ Heater inside the cabin blows lukewarm air instead of hot when the engine is fully warmed up
- ⚠ Steam rising from under the hood, especially after driving on the highway
Our Radiator Repair Process
- 1
When you bring your vehicle in, I start with a complete cold-engine visual inspection—looking at the radiator fins, plastic tanks, hose connections, and overflow reservoir for visible cracks, rust, or dried coolant stains that tell me where the system has been losing pressure.
- 2
Next we attach a hand-pump pressure tester to the radiator cap neck and pressurize the system to its rated PSI; this forces any slow leak to reveal itself, and if the source isn't obvious by eye, we inject UV dye and use a black light to trace it precisely.
- 3
Once the failure point is confirmed, I drain the coolant completely into a sealed container for proper disposal, then remove the radiator—disconnecting both hoses, the transmission cooler lines if equipped, and any fan shroud hardware that's in the way.
- 4
Depending on what we found, we either install a new OE-quality or OEM-equivalent radiator, or in cases of a single cracked plastic tank on an otherwise sound core, we replace the tank and reseal it with fresh gaskets—I'll always walk you through which option makes more financial sense for the age and mileage of your vehicle.
- 5
After installation we refill with the correct coolant type and mixture ratio for your engine, bleed the air from the system, then run the vehicle up to operating temperature while monitoring the gauge and checking every connection for seeps before we clear you for pickup.
One thing I always tell customers in the Gainesville area: Georgia's hard water is rough on cooling systems, so if you've ever topped off the radiator with straight tap water instead of distilled, there's a good chance you have mineral deposits narrowing the passages and accelerating corrosion—a flush alone can buy you significant extra life from a borderline radiator. A lot of people also assume a cracked plastic end tank means they need a whole new radiator, but on many vehicles we can replace just the tank for considerably less, especially when the aluminum core is still clean and straight. Finally, if your vehicle has an automatic transmission, the radiator on most cars and trucks also cools the transmission fluid through an internal cooler; when the radiator fails internally, transmission fluid can contaminate your coolant and vice versa, which is an expensive compound failure that's completely preventable if you catch the radiator problem early.
