A climbing temperature gauge or a puddle of green, orange or pink fluid means the cooling system needs attention. One call puts you in touch with an independent shop nearby.

Radiator repair and cooling system work protect your engine from its biggest enemy: heat. The radiator, water pump, thermostat, hoses and fans all work together to keep engine temperature in a safe range. We connect you with independent local providers who can pressure-test the system and find the leak or failed part.
Overheating is one of the quickest ways to ruin an engine. Dealing with a small coolant leak now is much cheaper than a warped cylinder head later.
Signs you need radiator repair
Keep in mind that some newer cars show only a warning message instead of a gauge. Know what your dashboard shows so you can react quickly if something changes.
- Temperature gauge climbing above normal, or a hot engine warning
- Steam from under the hood
- A sweet, syrupy smell after driving
- Coolant puddles under the front of the car
- Having to top off coolant often
- Heater blowing cold air on a cold day
- Cooling fans running loudly or not at all
What to do if your car is overheating
If the gauge climbs into the red, pull over when it is safe and turn off the engine. Turning the heater on full hot with the fan on high can pull some heat away from the engine for a short time while you find a place to stop.
Never open the radiator cap or coolant reservoir cap on a hot engine. The system is under pressure, and hot coolant can spray out and cause serious burns. Let it cool for at least 30 minutes.
Driving far on an overheating engine can blow a head gasket or warp the cylinder head. If the car overheats again right after cooling down, it is safer to have it towed.
If you are stuck on a busy road, turn on your hazard lights and stay well away from traffic while the engine cools. Once it has cooled, you can check the reservoir level, but adding coolant will not fix a leak that caused the problem.

Call (555) 010-2422What radiator and cooling system repair involves
The shop usually pressure-tests the cooling system to find leaks, checks the coolant condition, and makes sure the fans turn on at the right temperature. A combustion gas test may be used if a head gasket leak is suspected.
Many modern radiators have plastic tanks that crack with age, so replacement is more common than repair. A water pump replacement is needed when the pump leaks from its weep hole or the bearing gets noisy. On some engines, the water pump is driven by the timing belt, so shops often suggest doing both at once.
A stuck thermostat can cause overheating or a heater that never gets warm. Thermostat replacement is usually a modest job. A coolant flush replaces old coolant that has lost its protection against rust and freezing.
Radiator hoses can crack, swell or go soft with age. Squeeze a cold hose: if it feels mushy or crunchy, or you see cracks near the clamps, mention it when you call. A burst hose can dump coolant in seconds.
How to prepare before you call
- Note how high the gauge went and how long you drove
- Check the coolant reservoir level once the engine is cold
- Note the color of any puddle under the car
- Mention whether the heater still blows hot
- Say whether the car can be driven or needs a tow

Frequently asked questions
Can I add water instead of coolant?
In an emergency, plain water can get you to a shop. It does not protect against freezing, boiling over or corrosion, so have the system drained and refilled with the right coolant soon after.
Does it matter which coolant I use?
Yes. Carmakers specify different coolant types, and mixing the wrong kinds can cause gel or corrosion. Your owner's manual lists the correct type, and the shop can confirm it.
Can a radiator leak be patched?
Small leaks in metal radiators can sometimes be repaired. Cracks in plastic tanks usually mean replacement. Stop-leak products may slow a small leak but can also clog passages, so ask the shop before using one.
Why is my car overheating but not losing coolant?
A stuck thermostat, a failed cooling fan, a weak water pump or a clogged radiator can all cause overheating without a visible leak. A head gasket leak can also burn coolant inside the engine.
How often should I flush the coolant?
Many modern long-life coolants are rated for around 100,000 miles or five years, while older types may need changing every two to three years. Your owner's manual lists the right interval for your car.
