hi

 

Do we ever need to replace the coolant or just top up everytime it drop will do?

Sicne we don't have winters in Sillypore, flushing once every 2 years is suffice. If you notice drop in coolant levels often that means there's not enough coolant and too much water in the system or worst case a leak somewhere.

 

Recommended dilution ratio is 50/50 but I personally use 30/70 (coolant/water) for year round summer as water is the cooling component, coolant just raises the boiling temp. [;)]

i am not sure got any difference or not. but i just bought a bottle of ... Holts radiator flush. drain out old coolant, poke in water hose, just force water into the radiator, clean inside.... fill up with water & this flush, drive for 30-40 miles. drain out and top up with coolant. coolant i bought from carrefour, brand is "Total". A french brand.

Heard from someone that Merc coolant is better those out there in the market. I'm using Redline Water Wetter, about 370ml per bottle and top up ratio to 30/70 same like Turbobrick. One more brand is Engine Ice which is premix but quite $$$. Typically need 3 to 4 bottles to fill up the whole radiator(balance for spare)

Engine Ice goes for >$30 a bottle. But no lah, not 3 to 4 bottles unless Ur car super big radiator lah.. I believe about 3 is the max. So far mine (2.0 Stream) and my fren (2.4 JDM Accord) both use around 2.5 bottles.

But must make sure not using some premix thing though - else if just top up with water would have wasted the $$$ that went into the premix one.

If you car has green coolant currently, you could top up with plain water like Saaber mentioned and monitor whether does the level drop. If all ok then leave it, else top up with 50/50 (since not complete flush) water and coolant mixture.

 

For the standard green coolant, I recommend using CASTROL coolant which can be found at Autobacs or parts shop along Deskar Rd [:p]

 

If you're flushing do change to Merc coolant, the BEST! [thumbsup] Supposed to have water pump lubrication in it.

one qn, for older cars (with slightly rusty radiator), better to :

 

1) continue to use tap water

or

2) use market coolers?
