How to Stop a Leak in a 92 Camry Radiator

Like most relatively modern vehicles, the 1992 Toyota Camry uses an aluminum radiator, which can be repaired using a number of basic products. Minor leaks can be fixed with a stop-leak solution, which is pumped through the cooling system by the water pump and expands into cracks creating a durable plug. More intensive damage will require the use of an epoxy-based radiator crack-filling product.

Instructions

1

Raise and support the hood. With the engine off and having cooled down for at least 20 minutes, remove the radiator fill cap. Pour the contents of a radiator stop-leak solution into the reservoir. Follow the guidelines on the product packaging to determine how much product to add.

2

Replace the cap and turn the engine on, allowing the coolant to circulate. Keep the engine running until the coolant has warmed up and the leak has stopped. If the leak is severe enough that coolant is rushing out before the product has a chance to work, collect the coolant in a clean container and add it back into the reservoir after turning the engine off, then continue with the process. If the leak fails to stop after adding this product, then it's time to try a more direct approach to repairing the damage.

3

Kneed or otherwise activate an appropriate amount of epoxy putty designed specifically for aluminum radiator repair. Follow the product directions to apply it to the leak. Allow the epoxy to fully cure, preferably waiting overnight. Refill the radiator with coolant and start the engine to test the seal.
