Driving home from work yesterday and just pulling into my house an got a big smoke up fron engine bay an coolant buzzer come on so i turned it off the water temp droped from 67oC to 43oC i got out an there was 2liters of coolant on the ground i pushed it into the garage and it droped about another liter it looks to be coming from the back of the block i cant find an broken hoses any suggestions?

 

This search took me less than 2 minutes to find.

Check the hose behind the throttle body , that goes down to the engine mine broke and I couldnt find it either fora while

 

have taken off uim & tb still cant find where it coming from. tb cooling has been removed. there is no coolant on the top & sides of engine and when i add water it drains straight back out from the back off engine and bellhousing area, can see coolant on the clutch and flywheel is there any where on the rear of engine it could leak? dont want to have to drop the tranny out if dont need to

 

Freeze plug? on the rear housing?? If its inside the bell housing this is very likely

Isn't it winter down there on the other side of the world?

 

spring now down here i thought about rear freeze plug but i drove to work in the morning and there was no coolant leaking and none under car in afternoon. and why would freeze plug come out on drive home after car been sitting in sun all day and i warm it up before driving

 

If its in the bell housing

1. Random hole in the housing, cracked Iron??? not likely

2. Freeze plug.

3. Tension bolts. Maybe one of the seals around the washer gave out.

 

finally got round to pulling motor (lost licence week after leak so in no rush) was freeze plug in rear plate which was supposed to be new when motor was built >15k but cannot be as corroded as f*#k quick question tho can i just put new plugs in if old one came out from corrsion? and what can you do to stop them ever coming out (stupid place to have them but i guess not really anywhere else to have them) not cold enough down here to need them?

 

If the hole has corroded very much at all, you'll not simply be able to put in a new freeze plug. You can, however, buy these plugs that are made for this condition, they have an expanding function that seals a rubber lip around the hole. Any parts store has them.
