Replace the radiator core in order to fix leaks or blockages in your car radiator.
You may want to try this yourself, if you like the challenge of a new task or want to save a bit of money.
If you have a standard radiator then replacing it or using a radiator engineering company to recore it for you is probably easier to be honest. But if you can't get what you want or want to make a custom design, or you fancy the challenge of recoring it yourself then go ahead, it is not that difficult. It is very like a plumbing job with copper pipes. Just be careful that you dont apply too much heat and loosen up pipe joints or core joints that you don't want disturbed.
Although I didn't use a water tank to dip the radiator into, some guys do this to keep the core cooler. It doesn't make a huge difference if you don't go too mad with the blow torch. A water tank might be useful to check for any leaks during a pressure test but then you need to block off the oil cooler pipes completely. So I just did a water leak test which was easier. Take a look at the video. Doing this fixed the water leak in my radiator.
