Radiator & Cooling System Repair in Fort Lauderdale
An overheating engine can turn a small repair into a large one within minutes. Our technicians pressure-test the cooling system, find the leak or failed part, and repair it properly, with an honest quote before any work begins.
Cooling system repair built for South Florida heat
Fort Lauderdale heat and stop-and-go traffic keep cooling systems working at their limit. Plastic tanks and fittings turn brittle, hoses soften, and water pumps wear. We look at the whole system, not just the part that is leaking today.
Southport Auto Repair is a family-owned shop. You get a clear explanation of what failed, what it costs to fix, and what can safely wait. No pressure and no surprise repairs.
Radiator, water pump and cooling system repairs
Radiator repair and replacement
Cracked plastic end tanks, corroded cores and leaking seams. We confirm the radiator is the cause before replacing it.
Water pump replacement
Seepage, bearing noise or a wobbling pulley. On many European engines the thermostat is replaced at the same time.
Thermostat and housing
A stuck thermostat causes overheating or an engine that never warms up. Plastic housings are a common leak point.
Hoses, pipes and expansion tank
Soft hoses, brittle plastic coolant pipes and cracked expansion tanks are replaced before they fail on the road.
Cooling fans and sensors
Overheating at idle or in traffic often traces back to a fan, relay or temperature sensor.
Coolant flush
We refill with the coolant type your manufacturer specifies and bleed the system properly so no air is trapped.
Signs your cooling system needs attention
Temperature gauge rising
If the needle climbs above normal, pull over safely and shut the engine off. Driving on can damage the engine.
Low coolant warning
Coolant does not get used up. A level that keeps dropping means there is a leak somewhere.
Sweet smell or a puddle
Coolant has a sweet smell and may leave a green, pink, blue or orange puddle under the front of the car.
Steam from under the hood
Shut the engine off and let it cool. Never open a hot cooling system.
A/C warm at idle or heater blowing cold
Both can point to low coolant or a cooling fan problem.
How we diagnose a cooling problem
1. Pressure test and inspection
We pressurize the system and inspect the radiator, hoses, water pump, thermostat housing and expansion tank for leaks.
2. Confirm the cause
We check fan operation, thermostat function and coolant condition so the repair addresses the cause, not a symptom.
3. Honest quote
You get a clear quote before any work begins, including what needs attention now and what can wait.
4. Repair and verify
We fit OEM or OEM-equivalent parts, refill with the correct coolant, bleed the system and confirm it holds temperature.

Cooling system questions, answered
Is it safe to drive an overheating car?
No. Pull over when it is safe, shut the engine off and let it cool. Continuing to drive can warp the cylinder head or damage the head gasket.
Can I just keep topping off the coolant?
It may get you home, but it does not fix anything. A system that loses coolant has a leak, and leaks get worse.
Why does my car overheat in traffic but not on the highway?
At speed, air flows through the radiator on its own. In traffic the cooling fans do that job, so overheating at idle often points to a fan, relay or sensor.
How often should coolant be changed?
It depends on the vehicle and coolant type. We follow the interval your manufacturer specifies and test coolant condition during service.
Do you use the correct coolant for European cars?
Yes. European manufacturers specify particular coolant types, and mixing the wrong one can cause deposits and corrosion.
How long does a radiator or water pump replacement take?
Many are same-day repairs once parts are on hand. We will give you a realistic timeline with your quote.
Temperature gauge climbing? Don't wait.
Call the shop. We will find the cause and get your cooling system holding temperature again.
