I have a 1993 camaro Z28 which was in a front end collisoin, and has been undergoing extensive cosmetic surgery to put it back together. one thing I am not sure of is on the water pump, there is three heater hose like nipples on it two go the the heater core, were dose the third one on the drivers side go??
I was thinking it was just a extra one because this is a aftermarket carquest pump and pluged if. Is that suposed to be connected to somthing? I can not find any pictures on alldata relating to it

 

Heater hose diagram and radiator hose diagrams available on my Tech Page.

 

If its located on the bottom driver side it should be the connection to a bypass hose to the radiator.. the hose is connect to the bottom section of the radiator below the upper hose.... I have a '93... I'll go look....

 

It appears the one connection on the driver side goes to the oil cooler line from what I could see.... The to connection one the passenger side are for the heater core...

 

Oh, OK thats why I dont know were it gose I eliminated the Oil cooler when I reinstalled the engine... duhh. I'll just fill it with synthetic and not worry about a oil cooler leaking

 

If no oil cooler then you need the bypass hose:
