Cars cost too much.
Coolant prob.
Hmm.
My car seems to eat at the coolant it has in it?
Should I check if I have bled the system correctly and make sure there is no air in it?
I have recently replaced the thermostat and right hand side radiator hose...
Or is this normal?
I havent over filled the coolant resivour and it's a little warm at the moment but seems like it goes through it a lot.
There doesnt seem to be any in the engine oil.so thats good.
Doesnt look like there's any leaks... Hmm.

This was happening to mine, when it pressurised fully, it would leak out from the reservoir plug and also dripped from a heater hose right at the back of the motor.
Put a sheet of cardboard under the car overnight and look for spots in the morning. If no spots, you must be eating it when driving.

Just looked in under the radiator and the bloody thing was pretty empty. Filled it and made sure there was no air in the system... I think I need to talk to some mates and maybe trying the cardboard trick...
I had a similar problem,coolant going,but no leaks.It turned out to be a blown inlet manifold gasket.It blew out between the inlet runner and the water passage that goes to the manifold.I would never have have found it as it was running fine,then one day it just got real hard to start and thats what it turned out to be. (the inlet manifold bolts were loose which is what made it blow out) and now after I have fixed it ,it hasnt lost any coolant .Just the normal amount over a month or two.Apparently these gaskets are pretty common to blow and cause what you describe.I'd get the cooling system pressure tested(its as cheap as).To make sure its not the gasket.

I'll ask me mate that works at Holden about that man. Thanks!

Well, check the coolant level again today and the resivour is empty again! Grr.
Going to a mates work when I can to get it pressure tested for free.
Just put cardboard under it to check for leaks...
The best way to check for coolant loss is to have it pressure tested. Take it to a a radiator repair specialist or your local mechanic and have them perform the test for you. If there is a leak anywhere, they should be able to find it quickly enough.
Are you using coolant (green) or just plain water?

Green Coolant for sure. Im not gonna ruin my car with water. F*ck that!
It's going in tomorrow for a pressure test.
Yeah no that's cool, was just asking the question. Have a look at your hoses for small splits by looking for the tell tale green areas...

I recently replace the passenger side hose so that one should be sweet.
It doesnt look like there's really any leaks. So yea... I think it's the inlet manifold gasket...
funny that Ive the same problem,every time I put in up to 1ltr every couple of days , but was stumped Im also trying the card board trick and I think Brett jjj has solved it for me thanks for this forum Wombles
Cars cost too much.
I think I have the same prob as Brett jjj had... There's no drips coming up on the cardboard and no water in the motor so im suspecting the inlet manifold...
Im getting the cooling system checked tomorrow...
Just gotta find it and actually know what it looks like. Lol.
So I think this week, if it is the inlet manifold, i'll be changing that over ($84 for inlet manifold gasket) then i'll have to do the transmission service next week... Geh.
You will probably need the heater hose connector o-rings(where it goes into the water pump).Maybe even need the Injector o-rings and rocker cover gaskets. Depending on their condition .I ended up just getting a VRS gasket kit.(Valve Regrind Set).You still dont get the heater o-rings with that though.Holden have got them.Just take it easy when you dissasemble it all if you want to try to save them.You get the head gaskets with the VRS kit,so I removed the heads while I was as it.Cleaned them all up.I also noticed that where the plenum chamber fits to the inlet runners,(manifold)and also where the manifold runners meet the head intake ports that they dont match up properly.Theres a lip in some of them,which covered up to around half the intake port blocking it by half basically.I filed the edges down so the runners all line up properly.I finished them off with emery paper to get them smooth.It seems to run a lot better right through the rev range ,so worth checking out while you have it all out.Ive since noticed a lot of the ecotecs are like this.They should line up heaps better than what they do from the factory.Some are pretty straight ,and others are blocked by at least half.

I may have solved this problem a bit.
Found this when I was going to test the CTS.
Ok. I couldnt find my camera and my camera wouldnt upload the pic.
Its like 4 or 5 pipes that go into a connector. It's leaking there. It's near the brake booster and such.
It's left a fair amount of coolant on the engine bay.

Sounds like the heater tap.
My workin on the car face
Brand: Cargo
Series: Metallic Seal Up
welds cracks in engine blocks, fill find the leak and seal it up permanently. I used some of this to seal up an EF welsh plug and its still holding now. just read the directions, its miracle stuff mate and safe to use on any motor

Mate buy a new heater tap asap.
When they go you will lose all you coolant and mybe **** the motor.

I agree with Pete - they simply break and all you coolant disappears.....instantly.

Oh... Thats just f*ckin' great... I need my car for the next 4 days to get to work and around town... Now I have to buy a frickin' heater tap! F*CK IT!!!!
Ok, when changing it do I need to drain the bloody coolant as well? Grr @ Car!!!!
You will lose some, requiring the system to be bled but, no, a complete change isn't necessary. You can minimise the coolant lost by loosening the hose clamps first and lifting the heater tap and hoses out of the bracket, as high as is possible. And work quickly.

Buy a litre of coolant ( the same as you are using ) and add that to the topup.
As above bled system and have the heat open all the way to let coolant into the heater box.
Good luck mate.

Ok. I have a new heater tap. Been working on the bloody thing for an hour now. One hose off, one clamp off on another hose, 2 screwed hose clamps, a message about God giving us a better life, losing a flat blade screw bit out of my ratchet set later and here I am.

It can be a prick of a job.
I lost a bit of bark I tell you.

I've been having this same problem for ages, top up coolant and it slowly disappears over a couple of days to a certain level then stays there, can't see any leaks.
I've changed my intake manifold gasket (real fun job), disconnected the heater all together (bypassed the heater tap), and it still happens. And after a drive, the system doesn't appear to be pressurised.
I reckon I might have to actually pay someone to look at it

Go to a radiator place.
