If for some reason you damaged your Toyota Corolla radiator, you can fix small leaks using some silicone adhesive.
Its a simple job and you only need some quality silicone, like the kind used to form a gasket between two engine parts, a 10 and 12mm socket with wrench, wipes, cleaning alcohol and a thin flathead screwdriver. Some Sika Gasket silicone like the one in the video bellow should work fine. Here are the steps:
Let the engine cool off completely
Remove the two bolts fixing the radiator according to the video
Scrape all the dirt around the leaking zone
Clean it with alcohol to get rid of any grease
Wipe the area with a clean wipe
Apply the gasket silicone in a homogenous layer
Let it dry out completely and then start the engine
Wait for the engine to warm and circulate water through the radiator to see if it’s still leaking.
