jimny coolant loss

I have quite a bad collant loss at the moment, it on a sohc version.
I replaced several coolant hoses and also the metal coolant pipe and o-ring that come out the back of the water pump.
These were leaking before but are bone dry now.
Water pump gasket renewed and Thermostat gasket.
Not I have come to the conclusion that there were lots of leaks.
Are there any core plugs on this side of the engine (intake side)
Could it be head gasket or a cracked block.
Only leaks under pressure.
Thanks

I had the same problem and it was down to the plate on the back of the head held on by 2 10mm bolts theres a o ring in there that was gone on mine feel around the back of head the plate is about 4inch across removed that drain coolent first replace oring and I bet it fixes the problem toke me ages to find the problem till some one told me were to look

Unless you can find an obvious leak it would be easier to get a pressure test done.
It's quite simple and should only take a few minutes to get checked.
They just put a pump on your radiator cap listen/look for leaks.
I don't know if any of the fast fit places do it but you could ask around locally?? Saves you lots of frustration especially if the leak is internal

i would put money on the o ring

Thanks for the replies.
I have pressure tested it a few times and can't track down where it is coming from.
Sorry to say but I have just been and pressure tested again and the plate at the rear isn't leaking.
Good tip though I didn't know about the o-ring at the back.
It seems to be coming from in between the front cylinders on the intake side.

mine didnt leek all the time some times it would be fine then some times it wouldnt i tryed every thing even checked the plate on back for leaks and didnt find any but toke the plate of any way and the oring was knackerd havnt lost a ml of coolent since
