Get under the vehicle and look to see if you can see the leaking freeze plug. If you can't then it may be between the motor and transmission. If so, you will have to remove the transmission to replace it.
could be freeze plug, or intake leaking
it is probably your freeze plugs
Need to check the back to corners on the intake, they our none for leaking. There is 2 freeze plugs in the back of engine between the bell houseing and block.
There is a heater hose that goes to the left rear top side of the intake manifold and that fitting leaks engine coolant sometimes and it will run down the back of the intake around the distributor. If that fitting is not leaking then the intake manifold gasket is leaking coolant in the corners of it. REplace the intake gasket. That's all that can leak coolant on that year engine. If coolant is leaking out between the transmission and engine block then you have a freeze plug leaking in the back of the engine, between the transmission and block. Must remove the transmission and flywheel to fix it.
green fluid is engine coolant. as this is showing up near the transmission this could be leaking from the head gasket or from a freeze plug. you will just have to trace back where it is coming from remember there are freeze plugs behind transmission which are not viible while transmission is in vehicle
There are 2 freeze plugs in the back of the engine block were the flywheel is, They may be leaking. But I would look at the back top corners of the intake manifold real close and run your fingers around the corners and see if you get antifreeze on them. The intake Gaskets are none to leak on Chevy V8 and V6 engines, It is a common problem.
You will either have to remove the transmission are pull the engine out. It is what ever you think will be the easest for you. Then just knock the plug out, clean the hole with sand paper and drive the new one back in with a hammer and a socket that will fit in the freeze plug. Then put it all back together. There are 2 plugs in the back of the engine, replace both of them. You will see 1 plug in the center of the back of the block that is not a freeze plug, it is a cam plug do not bother that unless it is leaking engine OIL. Leave it alone.
you may have a leak in a hose and it is running to the back of the engine from the hose in the front and it may be a bottom hose I have a 94 model Ford and I had the same problem. I found out that the freeze plugs had cracked and rusted out till they began to leak.
You could have a loose or leaking freeze plug.
When the engine is removed from the engine compartment, and detached from the transmission, there are freeze plugs on the back side of the engine. You may be able to just disconnect the engine from the transmission, and loosen the motor mounts and lift the engine partially away to replace the freeze plugs.
You need to climb up and lean over the engine and run your fingers around the back 2 corners of the intake manifold and see if you get antifreeze on them. They are none for the intake gaskets to leak engine coolant. It is a common problem with the vortec engines. There are also 2 freeze plugs in the back of the engine where the fly-wheel is bolted to the engine that could be leaking engine coolant. There is also a heater core hose that goes into the rear left corner of the intake that could be leaking. The hose fits into a quick disconnect fitting that screews into the intake. It is common for the fitting to leak too,
MAN THIS DO NOT SOUND GOOD. IT SOUNDS LIKE A FREEZE PLUG HAS RUSTED OUT ON YOU. MOT LIKELY ITS ON THE ENGINE BLOCK BUT PRAY THAT ITS ON THE BACK OF THE HEADS. ITS EAZIER TO REPLACE AND WOULD TAKE A PERSON ABOUT 4 HOURS TO HANDLE.
