Coolant issues, need help
 

Alright, i just changed my water pump and coolant about a week ago. yesterday i noticed that my water pump is leaking out of the wheep hole. As i investigated, i noticed that my bell houseing was also leeking where the it conects to the back of the block. any ideas on what could be the cuase of this. There is no noticeable leakage around the heads or any of the normal spots. any ideas would be greatly apreciated.

Did you flush all the crud out before you changed it?? Also, did you use distilled water w/ the coolant, and was it Dexcool??

i did flush the system. and i used the orange gm coolant u can get at the store.

i had no leaks until i changed the water pump and a complete coolant change.

Sounds to me that if you are leaking coolant out the weap hole, that the bearing moved causing the leak(actually quite common) as far as having a leak around the bell housing, change the water pump and clean all the coolant that was leaked out. Run the truck for a few days and see if their is any leaks again.. in my opinion the coolant from the weep hole is blowing back by the fan making it look like you got a leak at the back of the motor.
