October 6, 200520 yr I pulld the water pump and It looked fine, except that one of the bottom screw holes was slightly erouding so I filled it up with a utlra blue and put a new gasket. Started it up and now It leaks even faster directly under the water pump. Does this pretty much mean I need a new water pump, or could it be something else? such as a problem with the block side of the waterpump? Thank you
October 6, 200520 yr Theres a small chance that the block side of the waterpump is damaged so that it wont seal correctly. What is more likely since u say that it leaks faster now after u took it off is that you didn't get it to seal perfectly. All traces of the old gasket should be gone on both the block and the pump. I like to use a little bit of brake cleaner and a rage and just run my finger over where the gasket should be. If there is anything really hard on there a bit of steal wool too should do the trick. I did all of this and installed a new water pump on my subaru and have not had a problem with leaks. EDIT: I forgot to mention when you put the new gasket on you should put a bead of black permatex on both sides of the gasket to help it seal up. Hope all this helps and good luck!
October 6, 200520 yr Author I did that, there was some slight gasket marks left behind but I did put ultra blue gasket sealant on all the screw holes.
October 6, 200520 yr Author The water is pouring out of a hole that is directly on the bottom of the pump, I am getting a new pump, but what is that hole and its purpose, I thought it was probably a biol over?run off valve or somthin.
October 6, 200520 yr Coolant coming out of that hole indicates that your pump shaft seals have failed.
October 6, 200520 yr Coolant coming out of that hole indicates that your pump shaft seals have failed. Yep, the weep hole.
October 6, 200520 yr Yep, the weep hole. Yeah, it's supposed to leak there to let you know that the seals have failed. I've replaced them when you still couldn't feel any other play in the shaft but I guess it was on its way out. The toyota pickusp will keep running till the shaft is so loose that the radiator fan bounces around and starts bumping stuff before it starts leaking. Not sure if that is better design or not...:-\
October 6, 200520 yr already said, but weep holes are classic signs of water pump failure. very common, time to replace. you're doing the right thing, just too bad you did it twice!
October 6, 200520 yr The toyota pickusp will keep running till the shaft is so loose that the radiator fan bounces around and starts bumping stuff before it starts leaking. Not sure if that is better design or not...:-\ My last pump on my EA82 spat out bearings and siezed. Weep hole never leaked a drop. I'd rather the weep hole let me know it's about to blow!
