yo lopez!

Welcome!

Steve83 wrote here that There are ~8 freeze plugs (and a few bore plugs that look identical) in a V8 block, plus 1 in each end of each head

you could start by removing the fan or shroud, then lifting the engine & removing that mount. If you still can't get it, you're on your way to pulling the engine - no wasted work.

& Yardape said in same thread; Ive done it that way before, undo the mount on the side you are working, lift the engine a bit. The remove the motor mount from the block and your set. To really make your life easier you can remove the exhaust manifold.

"...Freeze Plugs & Block Heater

Core Plugs

Removal and Installation

To remove a large core plug, drill a 12.70mm (1/2-inch) hole in the center of the plug and remove with an Impact Slide Hammer T59L-100-B or T50T-100-A or pry it out with a large drift punch. On a small core plug, drill a 6.35mm (1/4-inch) hole in the center of the plug and pry it out with a small pin punch. Clean and inspect the plug bore.

Prior to installing a core plug, the plug bore should be inspected for any damage that would interfere with the proper sealing of the plug. If the bore is damaged, it will be necessary to true the surface by boring for the next specified oversize plug.

Oversize (OS) plugs are identified by the OS stamped in the flat located on the cup side of the plug.

Coat the plug and/or bore lightly with an oil-resistant (oil galley) Sealing Compound E0AZ-19554-B or EZAZ-19544-B or equivalent and install it following the procedure for cup-type or expansion type below:

Cup-Type

Cup-type core plugs are installed with the flanged edge outward. The maximum diameter of this plug is located at the outer edge of the ******. The ****** on cup-type plugs flares outward with the largest diameter of the outer (sealing) edge.

Expansion-Type

Expansion-type core plugs are installed with the ****** edge inward. The maximum diameter of this plug is located at the base of the ****** with the ****** flaring inward.

CAUTION: It is imperative to push or drive the plug into the machined bore using a properly designed tool. Under no circumstances is the plug to be driven using a tool that contacts the crowned portion of the plug. This method will expand the plug prior to installation and may damage the plug and/or plug bore.

When installed, the trailing (maximum) diameter must be below the chamfered edge of the bore to effectively seal the plugged bore.

If the core plug replacing tool has a depth seating surface, do not seat the tool against a non-machined (casting) surface.

CAUTION: It is imperative to pull the plug into the machined bore by using a properly designed tool. Under no circumstances is the plug to be driven into the bore using a tool that contacts the ******. This method will damage the sealing edge and will result in leakage and/or plug blowout.

The flanged (trailing) edge must be below the chamfered edge of the bore to effectively seal the plugged bore.

If the core plug replacing tool has a depth seating surface, do not seat the tool against a non-machined (casting) surface.

Engine Block Heater

1. Open radiator draincock (8115) and remove coolant from radiator (8005) and engine (6007).

2. Remove block heater (6A051). Note the position that the element is pointed (eg. 12:00, 6:00, etc.)

3. Clean the inside diameter of the core plug hole machined surface and hole entrance. Remove any burrs at the hole entrance to avoid damage to the O-ring.

4. Cover rubber O-ring and core opening with a liberal coating of chassis grease (C1AZ-19590-B, C, D, E or equivalent.

5. Insert block heater in core plug hole in the same position as it was removed.

6. Tighten ***** in normal clockwise direction. Torque to 1.6-1.8 N-m (14-16 lb-in).

7. Refill cooling system..."
