1
Wait for a rise in the temperature gauge. Your radiator dissipates heat to assistance maintain the optimal operating temperature for your vehicle'southward engine. A leak in your radiator will upshot in lost coolant, which will compromise the system's ability to reduce that temperature. When your coolant system begins to neglect, the temperature estimate on your nuance lath will climb. If your vehicle has been running consistently warmer or if you take recently begun having issues with overheating, yous may have a leak in your radiator.^[1]
- Remember that overheating can cause serious damage to the engine in your vehicle. Stop driving immediately if your vehicle begins to overheat.
- If your vehicle has been running hotter than usual, you may have a slow leak, as there is still enough coolant in the organisation to keep the engine cool plenty to operate.

Take note of puddles nether your vehicle. An piece of cake manner to place a coolant leak is to find when puddles of coolant form nether your vehicle. Of course, in that location are a number of fluids in a vehicle's engine that may leak, so you will need to await closely and possibly fifty-fifty touch the fluid in order to properly identify it.

Open the hood and check again after a few hours of driving to see if the level has gone downward. If y'all did the initial check with the engine cold, wait for information technology to cool over again before rechecking.^[3]
- Coolant remains in the sealed organization and the level should not change.
- If the coolant level is lower upon your second inspection, information technology means that there is a leak somewhere.
four
Visually inspect the engine bay. If you observe more than rust and discoloration on the parts surrounding your radiator or on the radiator itself, that may be an indication that there is a coolant leak in the radiator in that vicinity. As the leak permits the coolant and water to escape the radiator while you're driving, it encourages rust to develop on the parts it comes into contact with. While all engine components can be subject to rusting, if you notice an area with an inordinate amount of information technology near your radiator, there may be a leak there.^[iv]

five
Use a pressure tester to locate leaks. You tin purchase a coolant organization force per unit area tester at your local auto parts store. To use it, make sure the engine is cool and remove either the radiator or pressure cap from your coolant system. Install the tester in place of the cap using the included adaptor. In one case the tester is secured and the system is one time again sealed, apply the tester to pump ten pounds of force per unit area into the coolant organisation. When the estimate indicates a loss of force per unit area, that means the pressure is currently leaking from the system. Follow the sound of the air leaking from the crack to locate it.^[10]
- Be careful not to add together more than than ten to 15 pounds of pressure (psi) to your coolant system. More than than that could result in damage and even create more leaks. Your cooling system operating pressure should exist listed on the radiator cap and you lot shouldn't exceed this number past much when pressure level testing.
- Await for whatsoever leaks that may be present on coolant lines likewise every bit the radiator as they may exist susceptible to cracking over time.

Replace the radiator cap and kickoff the engine. The leak will seal as the sealant makes its fashion through your coolant organisation.^[eleven]
- This method is not as permanent equally professional radiator repair or an epoxy, merely volition suffice to seal pocket-sized leaks until more than permanent repairs can exist fabricated.
- Allow the engine to run for 5-10 minutes while the stop leak product makes its fashion through the coolant system.
- After running it, allow the engine to sit down overnight as the sealant sets.

Employ epoxy to seal visible cracks. When y'all identify a visible crevice, clean the expanse effectually information technology thoroughly. Whatsoever remaining grease or clay in the area may forestall the epoxy from establishing a seal. Apply a restriction cleaner and a rag to help yous remove stuck on grime. Once the area is clean, allow it to dry out completely before attempting to employ the epoxy. Knead the epoxy in your hand until it becomes malleable plenty for you lot to spread it out over the cleft. Remember to be thorough and to continue the epoxy at least an eighth of an inch thick and then it can withstand the pressures of the coolant arrangement when the vehicle is running.^[12]
- You tin purchase radiator epoxy at well-nigh machine parts stores.
- Let the epoxy to set overnight before starting the vehicle.
3
Apply an egg to seal a leaky radiator. Eggs are not a good long term solution, but they can actually seal pinhole leaks in your radiator until y'all are able to have it properly repaired. Starting time past separating the egg yolks from the whites. Discard the whites, then put the yolks from three or iv eggs into your coolant arrangement through the radiator cap. Showtime the engine just as you would with a leak sealant and allow the egg yolk to travel through the coolant system. The yolks will congeal and seal small-scale leaks in your radiator and allow it to hold pressure long enough to get you habitation or to a garage to take repairs done.^[13]
- Using egg yolks could potentially lead to clogs in your coolant lines and is non recommended except in emergencies.
- This method is less reliable than the commercial products yous can use to permanently repair your radiator.
4
Utilise pepper to seal small leaks. Pepper is some other unlikely tool you can use to boring or cease a small leak in your radiator long enough to make it habitation or to a garage for repairs. Look for the engine to cool completely, so open the radiator cap and pour in near a half a pepper shaker'southward worth of common black pepper. The pepper, like sealant or egg yolks, will travel through the coolant system and get defenseless in the crevice as the force per unit area tries to flush it out. This will create a temporary seal that y'all tin use to agree coolant and pressure long plenty to drive for a short time.^[fourteen]
- Like egg yolks, this method is not recommended unless you are in an emergency and is less reliable than commercial products.
- Pepper may exist able to seal longer cracks than egg yolks, but is only recommended for minor leaks.
5
Cheque on your repair. Regardless of the method you used to seal the leak in your radiator, it's important that you check on the repair once you've given it an opportunity to set up. Afterwards driving the vehicle for a short time, keep an eye out for signs of leaking. If yous believe y'all may still be leaking coolant, deport the same tests to attempt to identify the source of the leak. At that place may exist multiple leaks or your repair may not have sufficiently sealed the system. Identify any new leaks and repeat the process.
- Egg yolks and pepper are not meant to be permanent solutions to a radiator leak. Consider using a leak sealant or epoxy to certain up the repair once you lot make it abode.
- Significant cracks may be beyond repair. In those cases, your radiator will likely need to exist replaced.
- Make sure to refill your coolant system with a fifty/50 water and coolant mix any time it is depression.
