How do you change freeze plugs on a 2.8L motor in a 86 firebird and due you have to take out the motor and transmission?
They can usually be pried out with a screwdriver and knocked back in. Most can be got to with the motor in place somehow. The 2 in the back of the block require either the motor or trans. to be pulled. For me, pulling the motor requires less effort. Less wiring and plumbing.
How can you see where the coolant leak is coming from It seems to me that its coming from between transmission and motor?
Why would water be coming out the back of your 1987 Dodge 318 motor are there freeze plugs in the back of the block?
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.
