How To Stop A Leaking Radiator

A leaky radiator is one of the most common problems for vehicles built in the 90’s and early 2000’s. This is generally a pretty low key problem if caught early, however it can cause serious damage to your engine if not given the right amount of attention. A good thing to know is that you don’t need to shell out hundreds of dollars to fix this issue. Believe it or not, you can actually stop most leaks with something commonly found in nearly every American household – coarse ground black pepper! Here’s an easy 5 step process on how to do it:

1. Park your car and let it sit for at least 30 minutes so that it has time to cool down. This is a critical step as if you attempt to open the radiator cover while the car is still hot, there’s a high probability that you will suffer steam burns.

2. Once the car is cooled, open the radiator and pour in about an oz of course ground black pepper.

3. Fill the radiator with the appropriate amount and type of coolant suited for your vehicle and replace the radiator cover.

4. Wait about 10 minutes for all the contents to settle, then drive your car around for about 15 minutes.

5. Park your car and place a piece of cardboard or newspaper underneath your vehicle. Come back in an hour and if there is no shiny green liquid on the paper, then you’re all done. If there’s still liquid dripping from your vehicle, then repeat steps 1-4 to see if the 2nd time around is the charm.

Bear in mind that if after trying this solution 1 or 2 times the leak persists, you may have a crack in your radiator and will definitely need to take it to a shop for repair. Additionally, remember that not all liquid coming out of the underside of your vehicle is a radiator leak. If there’s water coming out from the bottom then it could simply be runoff from your air-conditioning unit (assuming you were recently using your air conditioner). Needless to say, if there’s black stuff dripping from the underside of your car then it’s definitely an oil leak not a coolant leak and that in itself is requires a different solution (bring it to the shop). Last but not least, please try this radiator fix at your own risk – it has worked wonders for me and for many of my friends that I have recommended this to. Enjoy and happy driving!
