Default Weird water leak

Went out to start the car and found fluid on the ground so I backed her out topped her off took about 6 oz started her and no leak got her all the way up to temp and no leak . Put her back into the garage and ant out this morning and fluid on the ground looks like it’s coming from the center of the car . Oh felt the hoses and then popped the radiator cap and it seemed like it had pressure . Any ideas where to look ?

Probably just condensation from the Air Conditioner evaporator. It drains around the location of the passenger door, about a foot in from the side of the car.

If you have one, hook up a cooling system pressure tester to the system and start tracing the leak. If you don’t have one normally I’d say go to AutoZone and rent one, but I’m not sure they’re open. They’re cheap at Harbor Freight too.

Is the leak center front of engine or center back?

Do a pressure test as I described if you have the tool. Sounds like either a hose or the water pump. The pressure test will show it leaking.

Could the water pump cause what’s going on

Yes, there’s a seal at the front of the pump. You’ll see it leaking out from under pulley. With the pulley off you’ll see a weep hole on the bottom of the pump nose. That’s where it will come out if it’s the pump. If thats the case, I would send the pump to Haibeck and have it resealed and the bearings checked, unless you find a new/old stock AC/Delco pump. The Chinese replacement pumps that are currently sold are sketchy at best.
