Freez plugs does the head have freez plugs in the top of it

The 'freeze plug' is in the block, front and back, not the head.
I is a disk if thin steel that is an interference fit and will knock out to be replaced without dismantling the engine. The correct name is Core Plug.

On the side of the engine block and cylinder head There may also be some located on top of the head under the valve cover

Freeze plugs are round plugs in the cylinder block and cylinder head. they are pressed in not screwed in. The ones in the block are located along the side just under the top of the block where he head bolts on. The ones in the head are located down the centre of the head on top under the valve cover Also one at each end of the head

old post.
This is really a suzuki G16 engine question
thats ok,
The G16s are used on Suzuki's and Trackers
Vitara's , Esteems, no others world wide.

I have all the photos and books on those cars.
real books and all parts lists. on them , graphics tool.
the freeze plugs (core plugs on all over.)
IN 1996 only one engine, G16b.
But all G16 blocks these are the same.
sides on all G16 base blocks.
2 left side 1 above filter, one just to rear of that, they are huge.
have to be blind to miss left side, (left means same as left car door)

the problem here is there are 2 engines in 1995, then one in 1996
the heads on both engine are NOT THE SAME>
the head is 8v and 16valves heads
and the 16v has freeze plugs in the top ,next to the cam. inside under valve cover !!!.

why not say where the leak is so we can narrow the search. or state the JOB?????????

i have photos of all parts in any G16.
there are no freeze plug in any 8valve head.
but the 16v yes !!!
the 16v head small inside plugs, if leaking turn the engine oil to milk chocolate fast and worse of driven. (just undid worst)

the blocks are the same, both engines, not pistons,
there are no front or rear engine block freeze plugs only side plugs 4 total.
and sure the right side under intake man will be hard to see. look under car right side to see em.
2 left easy to see and 2 right harder.
the right engine block has 2 freeze plugs one in easy view center , under intake man.
and one tucked behind that water manifold that can leak too.
now the last plugs
the 16valve head has a front freeze plug behind the cam cog wheel. and none on the rear of the head.
so 1 front and 3 inside, top.
My guess, G16b has 8 plugs total.
G16a has 4.

things that go POP in the night (cold night)
the rear water outlet fitting (head) does explode every time one runs this head on pure water, frozen, ask my how I know that, and what clueless girl did that,, heheheheheheheheh

why ask this? if they are bad , the leak antifreeze, out side engine
or inside. both are obvious. green on ground, or engine oil
looks HORRID, like milk chocolate shake,
answer, there are core plugs (aka, freeze misnomer) are all over the engine, google freeze plug, under image. bingo.
on side of engine, (no engine option stated) on front and rear, in the heads, some have them on top of heads , inside the engine.

my guess someone said, check the freeze plugs. right?
to what question?

If you are in the cold freeze region then it can be FREEZE PLUGS or head gasket,

Freeze plugs prevent the coolant from cracking the block.

The only fix is to replace the freeze plugs.

freeze plugs pressed out by coolent not suffencient to stop freezing at your local temp. Reinstall freeze plug and look for more that may have been forcedout. common locations are sides of engine, and there are some in the very rear against the firewall.. head or engine removal neccessary.

There are freeze plugs in the Block usually under the exhaust manifolds where they are hard to see from top side and also there are freeze plugs in each head, which ones are leaking ? If you get the old one/ones you can replace with rubber expanding ones which don't have to be hammered in.

Freeze plugs are about half way between the bottom of the block and the top. They look like large bottle caps that have been plugged into holes in the side of the engine.

Check your coolant to see how low a temp it's good for. What u are describing is the failure of a freeze out plug. They are there to protect your block and head from cracking in cold weather, if you don't have sufficient anit-freeze protection (old anti-freeze, or not enough anti-freeze). If the water in the engine freezes, the freeze out plugs are designed to be a weak point, popping out to relieve the pressure of the freezing water, hopefully saving the head and block from cracking. The other reason for failure is corrosion due to, again, insufficient or old anti-freeze. To remove, u just need an old screwdriver and hammer, knock a hole in the plug w/ the screwdriver, pry it out. Clean up opening, install new one w/ block of wood and hammer. Of course, the location of the freeze out plug is what determines how much room u have to do this, so u have to decide if it's easier to pull the engine, or remove the head. It would be wise to pull the engine, and change all the plugs as angelo63 suggest, when done flush the system, adding a 50/50 mix of anti-freeze/water.
