Leaking coolant

[rvrftw]

OK... So I seem to be leaking coolant from somewhere under the inlet manifold. Are there any coolant pipes under there that could have split? I can't really see much.

I'm hoping there are some pipes back there that could have busted, and it isn't the head gasket.

What engine mate

4g63... And it doesn't appear to be the heater pipes

There's 4 welsh plugs under the inlet manifold, one of them could of given way. There the only thing under the manifold if not the hoses

 

[rvrftw]

OK... Do you have to remove the inlet manifold to access them?

 

[BRUSHED]

There a bit of a pain in the ass to get, if you cant get them from underneath you will have to remove the manifold. Jack it up and have a look from underneath to see how accesable it is, I haven't done them myself so not sure

Either the inlet manifold and starter. Or the tf case and Left drive shaft

Yep it appears to be a Welch plug.
Anyone know the size of the plug? And where I could get one?

 

[BRUSHED]

I just measured it to be 36.5mm, I'm not sure what that accounts to. If you go to preston motors and tell them your engine they will know, or someone here might have better info

 

[BRUSHED]

Even autobarn or someone like that will have them

He is in Tasmania.....doubt he has access to Prestons motors.

 

[BRUSHED]

I wouldn't know, do you have preston motors in tassie

 

[rvrftw]

Nope... We only just got roads like 2 weeks ago lol...

Although... We do have nbn... Gotta love downloading stuff at 10Mb/s

 

[BRUSHED]

Damn that sucks

Replace them all while you are there.
You could araldite a 20c coin in the plug if it is corroded. That will fix it for a while till you get the new plugs ordered in.

I pump air into the overflow pipe with a old style bike pump. Just pump till the hose is hard like when engine is hot. Dont overpump it...
this will let you see the leak. If its coming out the side of the plug, you may get away with removing plug, reflaring it a bit and resealing it.
There is also the fiav on the bottom of throttle body that may be leaking from the pipes.
