Radiator Leak Repair Cost
What Drivers in Nashville, Brentwood & Green Hills Can Expect
A radiator leak is one of those problems that starts small and gets expensive fast.
Maybe you noticed a sweet smell after parking.
Or a puddle under the front of your car.
Or the temperature gauge creeping higher than it should.
If you’re driving in Nashville, Brentwood, Green Hills, or South Nashville, understanding the real cost of radiator leak repair can help you act early — before overheating turns into engine damage.
Let’s break it down.
What Causes a Radiator Leak?
Radiators don’t usually fail all at once. They wear down over time.
Common causes include:
Corrosion inside the radiator
Cracked plastic end tanks
Loose or damaged hoses
Failing radiator caps
Damage from road debris
Tennessee heat and stop-and-go traffic only accelerate the process.
How Much Does Radiator Leak Repair Cost?
There’s no single price, but here’s what most Nashville-area drivers can expect.
Typical Cost Ranges
Minor hose or clamp repair: $150 – $300
Radiator leak repair (labor + parts): $300 – $700
Radiator replacement: $600 – $1,200+
The exact cost depends on:
Vehicle make and model
Leak location
Severity of damage
Labor access
A pressure test is usually required to find the leak accurately. Guessing almost always costs more.
