How to fix a leaking core plug

Hi there dear readers..
Hope you'll understand my very simple explaination to diy your own car.
If every time you check the water spare tank in your car was kinda empty or your radiator always need to fill up with water that is not normal, in my situation for long mileage car i have found water was dripping under hiding behind the intake manifold from the what we call it a freeze or a core cap.
So in terms to safe your budget rather to tow away your car to nearest workshop i suggest diy it and for cost is only take a few buck and a few hours depending how patient you are.

 This is how the core plug behind the engine block was found leaks in 4G15 engine. 

It its similar to any car ,but other car might be a bit confined place.Before that you gonna need to empty all wires, socket, fuel rail and intake manifold to make it more room coz you need a big hammer to punch in those new plug later.

Now you can clearly see where they are look like and easy to working on it.

Then grab a chisel or if you don't have one a flat screw driver could be work to punch in,but be careful not punching the block wall or scratching it,it could be worse scenario you gonna get a big problem. 

Just firmly hold the chisel a tap nicely with the hammer on the edge old core cap.than grab a long nose plier or vise grib plier and pull it out.

Well...it's pretty damn rust

There is still a water remain inside the block that you should drain it and make sure it's all dry.i use manual fluid vacuum for easy sucking what left inside

 I'd like to clear any debris left in,and that wasn't not only a dirty water, lot of steel rust i just grab it with a magnetic pickup tool.

wuiyoh..how that's can it be,at lease the coolant passage is now clean a bit.

parts is ready. im using the best gasket sealant from Permatex i get it from the nearest ACE hardware .

 double checking and take a measurement.

ready with the sealant. 

You don't need a special tool, just get a socket that fits the edge for the cap,mine was a 35mm core cap match with 26mm impact socket and get the hammer and wack it firmly and evenly. Leaving about 4mm at the end cap and make it sure is all in round shape not slanting.

The finished you'll have it.

The rest will be install back all parts together. Fill up coolant and water.check for anything left in the engine bay and start your engine,wait till temperature gauge is in normal until radiator fan is kicking and check for any leakage. Your mission accomplished. Tq
