I just found that the current coolant in my car*kelisa is kinda dirty.
Planning to flush the old dirty coolant out.
SO WHAT should i do? i had bought 1 bottle of coolant(my dad said it is enough).
Should i mix with the coolant with water or just purely pour all of it into the cooling system?

Thanks in advance.!

Open the Radiator Colant CAP and find the Another Output of the Coolant.
Then put the Pipe with water on flush into the Raditor Coolant and the Dirty will comes flush out at the output.

The next step you should know....

DO i need to repeat it few time or just 1 time will do?

what i did was..flush the old coolant..including the reserve tank
then fill in plain water..start engine for around 2 - 4 mins...and remove the water.. do the process a few times until u get clean clear water..by the 3-5 times the water should be clear already..then pour in ya new coolant and water, try to make it at 50:50..

anyway..make sure you start the process when the engine is cool

will putting tap water add residue to the cooling system piping since u all know how 'clean' our tap water is...

any advice from you guys?

what i do to top up when the reservoir is low is to use battery water (deionized water)...

normally i use mineral water
izzit ok for it?

the best way to do it is a complete flush

first drain the coolant through the plug at the bottom of the radiator... then fill up with water, tap water will do...

then start the engine.... wait for the radiator fan to turn on and when fan stops, unplug the drain plug again to let out water and fill radiator up with water. this is becoz when ur fan is on that means the water from the radiator is circulated to the engine and vice versa....
do this about 2-3 times to ensure all coolant form the engine and radiator is compleatly flushed...

after that pre mix ur coolant (with water, ususally distilled) in a CLEAN bucket according to the instructions on the coolant bottle (b4 this see the owners manual to determine how much coolant ur car needs)...

with this pre mixed coolant fill up the radiator when u drain out the water for the 3rd time (if u do three times la). then wait for the fan to on, then when if goes off, drain the water and put in the coolant. repeat this process till ur pre mix coolant in the bucket finish...... only close the radiator cap when the fan is on.... u may add a bit of distilled water to top it up...

and also dont forget to put some pre mix into ur resovoir

careful ya, its hot water.... and pls pre mix it first in a bucket before u start anything.... dont let the fan run without anything in the radiator... or else all there will be in the water jackets is air pockets..

good luck

mineral water got minerals wert... similar to tap water.

i use deionized water or distilled water.... not sure if there is really a difference between using distilled and tap water in the radiator though...

just thought that it would be cleaner...

distilled water is PURE H2O... while tap water MAY CONTAIN other contaminants that may cause sediments in the long run...
if flush then nvm la

Ouch. I can spot the nut to drain out the coolant. But seems like the space is insufficient for my hand to loosen the screw.
Any idea?
