Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
lts suggested 50/50 mix for optimal benifit in a application of this discription. When water boils it vapourises. Glycol may expand/ build pressure but not certain. Some materials such as aluminium require different care compared to a cast block to prevent heat sink or the effects are significant. I did read glycol can etch or deteriorate materials at a 》100%. Im not 100% certain that glycol doesn't evaporate but does loose its% overtime so a test kit is available to check. If mixed the water will evaporate. Some cheap s_#@ possibly deteriorates prematurely compared to the goods.Given the above theory this suggests that the ultimate then would be straight coolant. Just because it raises the boiling point doesn't mean the engine runs cooler. I could put in enough glycol to raise the boiling point to 180deg but in doing so the engine would probably overheat.
its to release pressure and cannot possibly prevent boiling, it just assist with circulating heat that builds pressure as the temp rises. So if water boils earlier, the steam vapours occur earlier than coolant, requiring a earlier pressure release. Therefore coolant is superior. If it fails it can pop your radiater tanks for eg:. Thats my understanding.Isn't that what the pressurised cap is designed to prevent..?
Hey all vx commy here
I have searched on here but have yet to find someone with the same problem
I seem to lose a little bit of water from somewhere. I have to top up and bleed the cooling about every 50-100kms with around a liter of water otherwise the temp rises (mainly while idling in traffic etc) I have recently replaced the heater tap, thermostat and radiator. Also when they replaced the radiator they flushed out the system but the problem still persists. I have tried looking for a leak while the engine is running but yet to find anything. I know these vx's have a lot of common problems. hopefully someone here knows what it could be.
Thanks

lt needs coolant within the system. Water isnt suitable and simply adding to what coolant is left however long ago it was added is diluting it further creating heat. It may be serging out the overflow, if it isnt functioning as per required you will always be topping up as you said in my opinion.
l dont know what plannet your from but hear on earth if you add water to glycole you dilute what you add to. As water boils before a water/glycole mix depending on %rate as its a varialbe number, the engine heats to the point water boils and vaporises creating a overheating scenario at a earlier temperature. A 50/50 mix raises the boiling temp and l assume reduces vaporisation to the point it assist cooling off the materials in a superior manner. So a cracked cylinder head for eg can occur much ealier cooled with water than with a glycole assist, appart from any other benifits of a mixture.Hmmmm, I think I completely debunked that myth in another thread. Do some research, it's all on the interwebs
99% certain it will the LIM gaskets as mentioned above. Biggest problem with the V6 motors unfortunately.

So what is your point!
