TD5 and waterless coolant

[MarknDeb]

Gday watched an episode of wheeler dealer the other night and Ed the mechanic was trying out waterless coolant for the first time and he went through all the benefits, so I started to wonder how it would go with the TD5, the best thing he said was once its in the motor you never have to replace it again, I liked that idea as well as the higher boiling point no pressure build up in the system because it has no water to create steam. Has anyone tried this with their car and how satisfied are you with it. If I end up going with this at the next service I will get the radiator replaced and all hoses and use the waterless, we still have the original radiator in the car so will bite the bullet before it goes on me.

if water-less coolant was any good, car manufactures would be putting it in cars at the factory.

they arnt. there must be a reason for this.

Argument doesn't hold water.

They can fill a radiator for maybe $1 water/coolant v (say) $5 for waterless coolant.

Yes it is quite a bit more expensive but when you work it out over 10 years it would be cheaper. Plus would makers be using it if it was going to reduce the sales of spare part. :angel:

Recent episode of 4WD TV showed how to change to this coolant. You need to use a pretreatment to absorb the water based coolant. Can't handle more than a small percentage of water. So if you breakdown and need to add coolant.... or have a slow leak... you need to carry this coolant as shops don't carry it.

yet manufactures are going with less servicing on items or longer between servicing times as they believe thats what customer want
coolant
engine oil
gearbox oil
brake fluid

im having a blank on other fluids at the moment

[Blknight.aus]

generically most waterless coolants are not waterless, mostly they are a water soluable oil

some are cross compatible with older coolants and water, some are very finicky about concentrations and pressures,

mostly they do what it says on the can or more specifically the product sheet thats devoid of the market speak blurb and full of the legaleese warnings. particualry the cautions part thats written by the techie types.


Very good stuff if used in the appropriate situations and in the correct manner.

Good to hear from you Dave and thanks, this is the info iam after so I can make a good decision

Good to hear from you Dave and thanks, this is the info iam after so I can make a good decision

being blunt, it sounds like you're looking for information to confirm a decision already made.

[Tombie]

I don't recommend it - it is a glycol mix, does build pressure, reduces cooling capability - like all high concentration glycol does...

And is as dead as poison...

Cooling systems are not set & forget... A coolant drop and inspection every 3 years minimum - annual if you want it A1...

A Google search will return many unhappy stories as well as happy ones...

No-Rosion Products Technical Questions and Answers (http://www.norosion.com/evanstest.htm)

some science


SUMMARY OF FINDINGS

Conversion costs of $259 if you do it yourself, or over $400 if you pay a shop to do it.

97%+ removal of all previous coolant is mandatory in order to prevent corrosion.

Inhibitor deposition occurs on aluminum surfaces, which could cause issues in some radiators.

Engines run 115-140oF hotter (at the cylinder heads) with Evans products.

Stabilized coolant temps are increased by 31-48oF, versus straight water with No-Rosion.

Reprogramming ECU fan temp settings is mandatory to prevent the fan from running continuously.

Specific heat capacity of Evans waterless products ranges from 0.64 to 0.68, or about half that of water.

Engine octane requirement is increased by 5-7 numbers.

Computerized ignition must retard engine timing by 8-10o to prevent trace knock.

Engine horsepower is reduced by 4-5%.

Accelerated recession of non-hardened valve seats in older engines is possible, due to brinelling.

Viscosity is 3-4 times higher than what OEM water pumps are rated to accommodate.

Coolant flow rate through radiator tubes is reduced by 20-25% due to the higher viscosity.

Race tracks prohibit Evans products because they are flammable and slippery when spilled.

[bsperka]

With all those advantages - high cost, extra heat, ecu fan reprogramming etc sounds like a winner to me.

Hiclone, Fuel Magnets, Electronic Rust Prevention and Waterless Coolant...

Tick them all off the list....

Electronic Rust Prevention

doesnt the navy use this on its ships?

Good to hear from you Dave and thanks, this is the info iam after so I can make a good decision

It probably wasnt the info you were after, read the summary of the techie speak in the quote in Eevos post.

[MarknDeb]

All that I have asked for, thankyou very much fella's. No my mind was not already made up on this Eevo, I received exactly what I needed from very well informed members either from personal experience or had heard about it. I will not be making this change when I change the radiator over

[iPom]

I thought about changing over a while back ... Then I thought... nah!. I'm running the factory spec OAT coolant and all is good. My simple and logical reason is the TD5 has been designed to run in nearly all enviroments on this planet and actually does a pretty good job. If your existing cooling is well maintained and performing as it should - why change?

Aren't ships in Water :)
