I have a 1990 ford mustang with a 2.3 liter moter and a freeze out plug come out is it to use a rubber or a nylon freezeout plug to replace it

FREEZE PLUG TOOL

CHECK PLUGS CHECK TIRES CHECK GAS FILTER

You might as well replace the engine, it is about the same cost. So you are looking at about $2000.00

on the block alone 8 or 9 ,plus the heads as they are cast iron not ally ,main one to leak that you can never find is the one behind the bellhousing ,No amount of additive will seal them thats for sure ,main cause of core plugs rusting through is lack of antifreeze ,where in warmer climates the fallacy is ,-- well it doesnt freeze in this place what do i need antifreeze for ,well its also an anticorrosion inhibitor

Odds are that the broken belt took out a vaccume line while it was flailing around,that would be the first thing that i would check for.Any hard plastic or rubber lines that are within stiking distance of the broken belt would be suspect.

Replace the Coil.

In one of the freezeout plug holes on the right side of your engine (passenger side) to keep the cord away from your steering shaft.Punch out the brass freezeout plug and remove the whole thing and install the heater if it is that style.
