I just changed my coolant to Engine Ice. All I can say is that I would have been better off changing it to the normal one. The temperature of my bike is as hot as ever. Wasted $48 of my money for a container of that coolant for nothing...

i think engine ice hav glycol content that does not transfer heat well..

Let me share my understanding of changing coolant for the bike.

 

Coz there are people who add pure coolant to their bike instead of mixing with water. This actually cause the bike engine to become hotter. Instead they should follow the recommended mixing ratio with distilled water or demineralised water.

 

Why? Purpose of coolant is for corrosion inhibition & also to raise the boiling point of water so as to prevent it from boiling. Too little coolant will therefore results in excessive boiling over & loss of water level in reservoir. Also corrosion & fouling of radiator will also occurs, coolant color will turn brownish over time. When radiator get fouled by rust scales, heat exchange will become poorer. This means more overheating. The back pressure caused by the choked tiny radiator coils/ tubings could caused the inlet rubber hose to bloat & maybe burst.

 

However, too much coolant will means lesser water %; which means lesser heat carrying capacity for the cooling system. Because water has extremely high specific latent heat - it takes a lot of heat energy to raise the temp by 1 degC. So too much coolant & too little water will prevent the heat from your engine from being adequately removed & trasnfer to the radiator exchanger for cooling.

 

That's why following the coolant recommended mixing ratio with water is extremely important.

 

 

Why its important to use demineralised water or distilled water to mix with the coolant? Because the dissolved minerals & chlorine inside tap water can effects the anti-corrosion chemicals within the coolant and neutralise it.

Anyone noes hw much coolant(ready to use) or coolant and water is needed for a S4 VTEC Spec 3? I wan to DIY my coolant flushing..But i dunno hw much to buy...

[Mussolini]

ready to use coolant can be bought at SHELL kiosk for $6 per 1l bottle. s4 uses 1.5lt. so u buy 2 is more than enough. no need water

ouh...ic ic...i've also heard about engine ice..izzit a good coolant or just ok ok?also need to put water also?

aniwaes..thx for the reply..totally appreciate it..

engine ice is premix.. no need addition of water..

juz buy the amt needed to fill yr bike coolant system..

Water base is the way to go, do a simple search, plenty of feedback.

Aight...thks bros...been great helps....

Get Maxima Cool Aide. Its premix. Cannot go wrong. Moreover, its cheap.

[BOGEY102.1]

hi bros,

 

can't seem to find distilled water anywhere. can only find battery water. are they the same? can use to mix with concentrated coolant?

 

thanks for your advices bros

Go to watsons. They sell distilled water in 1 litre bottles.

Actually I find it questionable if those are really high purity water. The reason is that slight mineral content does nothing harmful to human body, but will cause deposit problems in radiator systems in long run. Premix simple and quality guaranteed.

 

Maxima Cool Aide Premix

[mtyw8888]

anyone use MAXIMA Coolant? hows the feeback? Any diffs?

[tt6389]

I just changed to Maxima Cool Aide pre-mixed yesterday night at raceWerks. Good thing they close at 9pm. Its so convenient, go there after work not much waiting.

 

The pre-mixed comes in 1.8liter bottle but my S4 capacity is 2.2liter according to the manual. Coz my petrol tank needs to be removed for coolant top up, the mechanic couldn't runs the engine continuously while adding the coolant. Because of this, it was extra slow process . So he decides to fill reservoir almost full & balance a bit leftover. Problem here he only used 1 bottle of the Cool Aide & I only found out my coolant system capacity is 2.2liter later today. My temp was a bit hotter than normal during cruising & traffic stops. Hopefully it 'll be solved when i topped up the rest of 0.4liter.

 

I should be going back to see him for additional top ups - hopefully without having to buy another 1.8liter bottle.

 

 

[ANR Impex]

tt6389, just pay attention to your reservoir for the next few days and top up with your balance. The system automatically tops up to the radiator from the reservoir as your bike goes through a few warm up and cool down cycle.

 

The Ready to Use bottle is stated as 1.89L, but I have measure the contents before, it is easily 2L. The manual always state a volume that's more than you'll ever fill it to, because there's always liquid trapped somewhere inside no matter how you drain.

 

A more efficient coolant like Cool Aide will heat up faster when stopped or in slow traffic because it is doing its job sucking heat away from the engine faster. The temperature drop is when you ride at expressway speeds. When you ride NSHW speeds, the drop will be even more.

[tt6389]

thanks, will monitor for level drop.

just now was flushing my coolant using Vinegar mix w battery water...I notice tat my temp rise super slow...wonder by using this mixture for coolant will it ruin my engine or other parts.......

[ANR Impex]

You do not want that in your system aside from flushing. It does not have any anti corrosion properties. Flushing with anything other than water usually opens up a can of worms, depending on the condition of your cooling system to begin with. Regular coolant change once every 12 to 18 months is a better idea.

vinegar & water is acidic - not supposed to use acidic stuff in yr coolant system for too long. Coz it will eats your engine metal also.

this got me really curious

i've recently replaced the glycerol coolant in my bike with ready mixed coolant available from Shell

 

previously, the bike was able to maintain the temp gauge at 1/4 when travelling on expressways. it rises to 1/2 when i get stuck in jams or while waiting for traffic lights on a hot afternoon

 

now after the coolant change, the temp gauge climbs to 1/2 even when im travelling on expressways during hot afternoons

havent really tested it out during jams though

 

hence, i would like to seek some opinions frm the bros here if my new coolant is so called 'sucking the heat away faster'?

[DM]

did you burp your radiator? did you fully remove air from your cooling system? try to open your radiator cap, top up with coolant and shake your bike from side to side. if you're afraid of it falling, just start the engine and rev a little after topping up the coolant. when you rev, the coolant pump sucks in the coolant and helps to displace air so u can fully fill up your cooling system.

If your temp is hotter even during constant speed expressway riding, the coolant is not working as well.

 

The only time when a better 'heat sucking' coolant will heat up faster is when you're not moving.

 

When you're moving, a better coolant will move the heat more efficiently to the radiator to be removed to the airflow, the end result is a lower temp overall.

 

Also, all temp references can only be taken as a judge of coolant performance after your bike has fully warmed up. For smaller cc bikes, it can take longer than 20min on a cool day. Before that, you might just be noting another property of the coolant known as the heat capacity. A high heat capacity coolant takes forever to warm up but can be a bad conductor of heat.

thanks enfant and ANR Impex for the replies

guess i will consider keeping the coolant ard for another few months then get it replaced

will continue to monitor the temp gauge closely

 

anyway i notice that pple tend to recommend a 50%-50% glycerol and distilled water mixture

however, this Shell ready mix states on its bottle a 33.3% concentration

is this supposed to be good or bad?
