How do you replace the housing for the water pump on a 2000 Chevy Camaro V6?

there is a weep hole bottom of water pump at the pulley area if it is coming from there it needs to be changed

Could be anti theft. See if the security light is flashing on the instrument panel.

Hopefully what you have shown is behind the water pump and the leak is water and not oil. If it is water you need to replace the water pump and its seal, if not, the engine will require much more detailed tear down. Get yourself a Haynes repair manual for your 2000 Camaro V6 at your local auto parts store and check out the engine parts locations.

have a coolant system pressure test done and look for leaks at the welsh plugs, water pump hole under water pump, heater core inside

If it's a V6, it could be, or it could be the bypass house (which is recommended to be replaced when you do the timing belt/water pump at around 105,000 miles)

Check the fuel pressure it souds like you might have a weak fuel pump.The fuel pressure should be 60-66 with key on engine off.

Thanks for choosing FixYa and welcome. Did you check your impeller?

take it to a mechinc shop and have them do a pressure test

It is your Lower Imtake Manifold gasket (LIM). Late Production Camaros and Firebirds used Dex-Cool coolant which nortoriously caused the LMI to actually disintegrate. The failure of the LIM allows coolant to leak to the exterior of the engine as well as into the interior of the engine eventually getting into your oil. Check your oil for a brown milky color... if you have it immediately drive your car to you favorite repair shop and replace the LIM gasket. The GM 3.1L, 3.4L and 3.8L engines are famous for disintegrated LIM gaskets and a good shop will have replaced 30-50 of these in a year. The LMI is part of the reason the public dissed Pontiac and eventually led to its demise (not to mention bad management at GM). Find a shop familiar with the LIM problem and it shouldn't cost more than $500 to replace (or less). If you have any mechanical skill you can replace it yourself... the gasket kit costs about $35 at NAPA AutoParts and it takes a whole Saturday if it's your first time. I just finished replacing the LMI on my wife's '94 Firebird.
