Just replaced my waterpump and now there’s coolant coming from the lower rear left side of the block. Any thing can help, I haven’t changed the intake gaskets yet thanks.

Most likely a core plug, intake gasket, or cracked casting.
If it's a vortec, it's likely the intake manifold gaskets. On vortecs you need to put aviation permatex gasket sealer on the pump mounting bolts. Some of them go into the water jacket and it WILL LEAK if you don't. Also use the same sealer on the pump gaskets, and be sure to check the rear plate bolts on the Chevy water pumps. I've seen them new with loose bolts.....
