Water loss

[losh1971]

And yet you completely ignore the bit about the cooling system been pressurised. Water under pressure does NOT boil at 100° C this is scientific fact. I've posted links and charts with the relevant info. Pressuring the cooling system raises the boiling point of the coolant much more than running a 50:50 mix of water and glycol. You can keep posting the same dribble but you are factually incorrect and completely ignoring a major component/function of a pressurised cooling system. You also completely ignore the fact that the V6 ecotec/L67 normal operating temp is from 91°C to 104°C (thermostat temp to low speed thermofan on temp)..

It would appear that @gohrdrgomad just like to ague with you Immortality because I have twice asked him a question explaining what I know and what I have experienced with boiling yet I get no reply.

The OP's problem is that the engine is loosing coolant and it's 99% likely that the intake gaskets are fucked. When this occurs the engine will slowly loose coolant via the combustion process. If the gaskets get bad enough than the cooling system will not pressurise correctly and an overheating condition may then occur. In this case the failure has no direct link to the type of coolant used but rather a loss of coolant and lack of pressure in the system.

I have no disputes regarding a possible cooling system failure as l mentioned to "ORTHAS".

Adding water has not fixed it, it has reduced the possible boiling temp characteristics of what mix was provided buy the repairer. The repairer did not add plain water for a reason.

So why highlight your possessive need to question me, thats if this is in fact a genuine thread and not a concocted baited forum convisation for your pleasure.

Unless you Immortality physicaly diagnose an engine in person or by remote correspondence including dismantling the engine you are just speculating.

Providing whatever you have stated in hole, its realy not a firm diagnosis at this stage, your chemistry resurch piontless.

Some of your dribble is about bagging the charactoristics of additives recomended by vehicle manufacturers that you disagree are nessesary, or whatever else drives you disliking.

As l support following the manufacturers guides and not you, is it possible you feel enraged by my choice, and you choose to harass in your sly ways.

Could that explain your posessive need to address my general advise/oppinion as a forum member to "ORTHAS" thread rather than provided your advise to him direct.

If the factory cooling system is functional, the recommended additive will assist the engine within the set manufacturing specs.

"ORTHS" stated he/she couldnt find a thread with his problems.

Yet you say you have covered all this before. Rather than create a science debate for your enjoyment as you stated, at this stage it has no grounds to support what seems to be "OTRTAS" issue.

My suggested application of a coolant mix has been pinpointed buy you as factualy unessesary/incorrect.

You seem to be gratifying yourself with a empty diagnoses.

Grow up!

Fact is the OP has a coolant loss issue and has a ecotec V6. LIM gasket failure is what I would consider the number 1 failure point on the cooling systems on this type of engine. So it is highly likely the intake gaskets are toast and possibly have been for a while, initially when these gaskets fail the coolant loss is very slow but as it progresses it becomes worse until one day you end up with a radiator full of air (this exact issue happened to a work mate of mine).

Am I familiar with this failure, yep I sure am, I have replaced these gaskets on my own vehicles as have mates on theirs as have many forum users who have come to this forum with similar coolant loss issues although many catch it when the coolant loss is slow. If there is no external sign of coolant loss than it must be internal....

When you are loosing coolant (of any description) simply adding more coolant will NEVER fix the problem.

In your original reply you blamed the use on water as a cause of overheating, this is clearly false and yet you persist with this argument when it's clear you can only go back to a manufacturers recommendation and nothing else concrete like scientific fact and real life experience by myself and other users on this forum. Seeing as a spin my own spanners and have real world experience to back up my position, you seem to have an owners manual....

At this point the OP can add what ever he likes to his radiator, using a 50:50 mix of water and glycol will only hurt his back pocket more than using just water until the actual fault is rectified.

If I had the vehicle in front of me I probably could diagnose it in short time but in this case the OP has come of a forum seeking the knowledge of those who are experienced in these issues and these are the joys of diagnostics via the interwebs.

I note your ride says Vxcaly57, do you actually own an ecotec or have ever done so? Are you at all familiar with the ecotec or just what you read online?

To the OP,

1. Does the engine overheat during normal use if the coolant system is topped off?
2. Is that any sign of coolant in the oil?
3. Remove the oil filler cap and check for condensation/milkshake like scum under the cap
4. Is there milkshake like scum under the radiator cap or in the overflow bottle or was there before the cooling system service?
5. How long has the vehicle been using coolant/at what rate (before the current litre/100km)
6. Other than loosing coolant, is the engine running normally or are there other symptoms present?

If the manifold gaskets have not been replaced before or if they have used the original type that have 180k on them they will be knackered. Like Immortality has pointed out among others the original manifold gaskets on the Eco and Buick have a limited life span. If the OP can't see a drip then to pull the manifold and replace the gaskets would be the first thing to do. Its a PITA that takes 3 or 4 hours but it is what it is. The job is straight forward just time consuming because of the cleaning.

your original reply you blamed the use on water as a cause of overheatin

You do seem to read/dissect things the way you choise to manipulate it. Not "the cause" a possible contribution to a overheating scenario within a cooling system failure as a result of lowering a boiling point to below a possible maufacturers specification as dilution of a mixture can do so.

Good to see you got off arse!, rather than your sly harassing front to a members general feedback response.

 

[gohrdrgomad]

Yep, I'm like a dog with a bone when it comes to people and old wives tales.

So, out of curiosity, which are you, hard or mad?

Yep, I'm like a dog with a bone

Yes you are.

Is this to intimidation, antaganisation, harrasment of a forum member for your own and others pleasure!

 

[gohrdrgomad]

Yep. It's been fun though, otherwise it would have been a very long and monotonous evening .

lt seems your honesty highlights your twisted sly dog with a bone manner, towards myself for the pupose of your self grattification for added enjoyment.

 

[losh1971]

Can we just let this go now, and get the OP to remove his manifold and see how knackered his manifold gaskets are?

To the OP,

So do you suggest adding glycol mix will create damage compared to adding water considering the cooling system failure. You do stress a particular disliking to its mix used in this engine.

To the OP,

So suddenly you addapt my suggestion to attend to the thread lead itself.

The general cooling system failure discription provided, didnt demonstrate ability if any mechanicle aptitude at all. Best bet take the car to a cooling specialist have it assessed. As done previose supposedly.

note your ride says Vxcaly57, do you actually own an ecotec or have ever done so? Are you at all familiar with the ecotec or just what you read online?
