Juz use water for radiator??

[Clawer]

sorry to cut in ah.. so can use battery water for radiator ah???

[Genie47]

Expensive leh! Distilled water for battery is more pure than distilled water used in radiator/coolant system. Go buy from Guardian Pharmacy. $1 for 1.5L of distilled water. Good for drinking, good enough for radiator but don't use for battery.

Better than using recycled shi*-water from tap (Newater, that is) Edited April 11, 2005 by Benhew05

I have this nice wallpaper from Big-O. Shows this very dirty squat pan type toilet bowl. Very dirty like from public toilet never washed for years. At the bottom it says.....ABSOLUT NEWATER.

 

Damn sad! We drink Newater and our cars get at least distilled water for coolant system.

hey Genie, thanks for the very detailed write-up!

 

currently using redline waterwetter mixed with Guardian Pharm's distilled water. btw, it's $0.70 for 1.5L...

 

took me quite long and a lot of water to flush out the original coolant

[Cyrix]

bro...will waterwetter actually bring down the temp of the engine???...wil it show on the water temp guage???...cannot really c leh....btw...i kpo and put in two bottles of the waterwetter....will it have adverse effect???....wondering whether putting too much will affect anything or not.....

[Genie47]

You used water only to flush? Actually, good enough if the car is new. Don't anyhow mix Waterwetter with any other antifreeze. Got reports of strange results. Muck building up everywhere. Do note that Waterwetter has lower overboil protection compared to conventional antifreezes. But its surface tension lowering ability should make up more it it.

 

Some data to take note of for your next coolant change:

 

50/50 antifreeze/water = 109C

50/50 + Waterwetter = 104C

Water only = 104C

Water + Waterwetter = 94C

 

Water + Waterwetter only is best in race vehicles but not street vehicles! Some recommend at least 15% antifreeze which explains why Apollo recommended NOS antifreeze/coolant to be used in conjunction with Waterwetter.

[Jamesgetz]

yeah, used only water to flush but loads of them that is. went through at least a few cycles of drain, fill-up radiator, run engine, repeat... in between the cycles, pour loads water into radiator

 

eh? i thought u don't recommend mixing coolants and waterwetter? how do u know the NOS coolant will work well with waterwetter?

 

thx in advance!

[Jamesgetz]

no doubt WW is good but i think there's far too much hype and misrepresentations by users.

 

to answer your question: no, your temp gauge should not be lower than what it was since the temp is ultimately controlled by the thermostat. a better coolant alone will not reduce the engine temp and improve engine performance but will help your water pump and radiator to last longer.

 

and i think you have put in far too much WW. read the instructions carefully. each bottle can treat 12 to 20 quarts of water which is about twice the size of most radiators. 2 bottles of WW in 1 radiator is 4 times the recommended concentration...

[Genie47]

You got to ask Apollo. Some antifreezes don't like WW. Got some reports here and there. I think this is the OAT, HOAT or Toyota/Honda phosphate type. People have reported WW forming some sludge with it.

 

I don't recommend mixing because car too expensive.

darn... thanks anyway

 

now my radiator fluid BP is less than pure water BP . sigh, should have just stick with the stock coolant and not worry about lowering of BP, problems with coolant mixing...

[Genie47]

It will not bring down the temperature. It is a surfactant that actually makes the water lose its surface tension and hence "wet" the surfaces more evenly helping to transfer heat.

[Beanoyip]

Just a check, if the engine temp is normal, the indicator should be in the middle? Not higher or lower? Is that true for most cars?

[Frankloh]

Not really, some cars is at the half mark.

Think Suzuki is at 3/4 mark....very high very scary

[Lanceteo]

for my car is abt 1mm below the center mark. according to tan cheong motors whn it rises more dan tat. means something is wrong. get it checked . yeap.

[Beast]

no leh.. my swift is at center mark..

[Beanoyip]

Somehow this varies from cars to cars... Think we should do a poll on this.. haha

[Genie47]

Slightly lower than the half mark or very close to it. Seldom at half. I only see half at traffic jams.
