Did you change the gasket on the water pump? Is it coming out the neck extension off the intake? Not sure if your corollahas this? My sienna has this and would leak antifreeze if intake gasket was bad on side of timing belt.

It has oring which I changed and timing chain not belt......thanks for reply


How well did you clean surface of water pump mating area on engine? Did you do the proper torque on pump nuts? They are not much like 70 inch pounds. Look them up don't take what I said. I just know they are about 15 foot lbs.


There is a product when put into the coolant will show up florescent when hit with a light you should see the origin of the leek. after you wipe it all down the best you can it should give you a good idea where its coming from.
