Coolant leak

[Tavoris]

Right side halfway back on the bottom there is a circular plug missing.. On the engine coolant is flowing out.. Any idea of the name of that part?

A freeze plug goes there.

Im guessing the coolant is coming out of there really fast? Haha

Yes exactly.. Would you know a price range? Is it metal? Does it screw on?

Quick search on summit shows this. https://www.summitracing.com/parts/slp-381-8010/applications/year/1998/engine-size/5-9l-360

There a few different types of freeze plugs or, "expansion plugs" and different ways to install them. Some use special tools.

Usually it is easiest to grab a socket that fits inside the plug and hammer the plug into the block.

Just to double check your truck does have the 5.9 magnum gas engine right?

Should be 1 5/8" expansion plug. They are available in OEM style steel or brass, which drive in, or a universal style metal and rubber which you insert and turn a nut to expand the rubber to seal. As a FYI, I usually install small block Chevy ones - they are the same diameter, but taller.

How can you tell if it's a vacuum leak or a head gasket problem?
