Coolant or water?

[Guest E200]

For W124, should use coolant or water?

Some say coolant is no good for our radiators, since they are old and coolant has properties that are likely to "thin-off" the metal.

While we know that water will cause rust inside.

So how? What's the best advise?? :la:

Suggest u use Merc original coolent (blue color).

Dont try using straight water, there will be long term side effect like rust and slug

[keltanky]

yes what alumetal said is true.

Best use Original Merc coolant (blue color)

never try use other coolant, it will eat up your gasket!! :censored:

after kena eaten up, sure :death: must do overhaul engine liao!! :banghead:

well i lazy, i used H2O, but mine isn't straight from the tap,

( you can call me crazy, but i only pour in H2O which is stored at rest for a few days, and i dun pour all from the bottles, just got the feelings that the other chemicals from the tap and settled down to base, follow my dad's routine la... :wifstupid:)

If there is a real needs to use straight water,.....use distill water.... you can buy them from Giant .... Watson...etc

Note : Distill water !! not minerial water !!

Some schools teach a 50:50 mix. Using distilled water is absolutely vital. You don't get calcium deposits over the long term which is actually the sludge you find at the bottom of your radiator if you ever drain it in future.

Coolant (usually ethylene glycol) has a higher boiling point than water so when it is mixed with water, you tend to marry the best of both worlds.

The distilled water aids in a more efficient heat transfer vs the not so heat absorbing properties of pure coolant. Coolant also prevents corrosion.

Yeap !!! Thanks the trick i learn !! which cost me some S$2000 for top-overhaul !!

*Toyota coolent is OK (i used them before), but ensure a total 100% drainage of other coolent + full flush......mixture ..... complication at later stage..

[Guest Mike]

mine is full flush and i drain it at every 10K when i have my oil change

[Guest alumetal]

waulau !!!! every 10K !!!

[Guest starnite]

can flush ourself? where is the cap at the bottom?

[Guest noelhon]

jialek, when i go my 1st service, the mechanic just pour normal water into it. will i be in trouble? hope it dun kill my car off......

[Guest Mike]

I am using HEPU coolant from Germany. They are manufacturers of HEPU water pumps.
