is it ok to put 100% coolant instead of water in radiator and also their backup tank?

I thought need to mix some with water, no?

normal coolant kenot...


specialized coolant can

look for "evans waterless coolant"

why do u even waste money to buy 4L of concentrated coolant when water is free?
the ratio is 50/50
50% water, 50% coolant

Actually to get best result, one should mix concentrated coolant with RO water (not tap water) at the ideal ratio.

Anyhow, Shell has a pre-mixed coolant (factory mixed). No need to add water. Do a complete flush of ur system b4 adding this. Barring any leaks or hose breakage, these can last very long.

Just follow the instructions on the coolant bottle, no need to think coz it's not rocket science. If it's premixed coolant, then usually it will come in a gallon or 4ltr bottle then can use everything without anymore water. If it's concentrated which normally will come in 0.5-1ltr bottles then you need to follow the mixing ratio with additional water (usually like 50/50).

Not good..actually water is better in cooling down the heat, coolant act more as an anti rust

For Honda, at least my city. They advised not to put water, all coolant. But coolant also has many type. Some pre mixed with correct ration already.

It all depends on the coolant you're gonna use. Some already come premix (no need to top up with water) while some will require it. Just read the container's instructions.

actually thinking of changing to 100% coolant due to water vapor very quickly at 100c.. so using coilant is the best to keep the temp down for a longer period.. as coolant need more then 100c to boiling state and at same time also can protect inside the radiator itself

i might try the shell brand one.. any othe brand can suggest.. very much oblige..

If your coolant evaporate too quickly that means your car has overheating symptoms already, or your radiator cap already spoiled, or you got some leaking somewhere hence coolant level drops too fast.

Haha.
You either have a blocked radiator or a malfunction radiator fan.

As for coolant, read the damn instruction or your whole radiator, radiator hose will suffer.

if that's the case, some part of your radiator has problem
got nothing to do with coolant
it's the water that cools your engine, the coolant acts as anti-rust
if it vaporized means somewhere is leaking or clogged

Yes, coolant has higher boiling temperature, but water has more "heat carrying capacity", where each degree the water temperature increases captures more heat compared to coolant.

If you're losing coolant quickly and there are no visible leaks externally, meaning your head gasket is very likely gone bad. The coolant seeped into the combustion chamber.

1/ engine cooling system is in a sealed, pressurized system. being in a pressurized system, the boiling temp is raised above 100c.

2/ one of the purposes of coolant is to increase the boiling point of water so it can hold and transfer more heat away from the engine and into the radiator.

If you're using a 0.9 bar radiator cap. Water would only boil at about 118c.
If you're losing coolant. Check for leaks, sign of head gasket problem and etc.

And if you want to improve the cooling, go for 30% coolant and 70% distilled water.
Enough to lubricate and protect the cooling system and having better heat capacity for heat absorption.
If it not enough, try Redline water wetter or Dei Radiator additive.
If you want more, use aluminum radiator and a bigger size and with high flow radiator fan.
But

thanks for the tips guys... i will try to what your advised here.. new car nowadays dont have temp meter like old cars... got indicator only... if the indicator showing suddenly it is already to late... that are the really scary shit ..

mesidis still using analogue gauge for temp

if can reach 100c...need to monitor your cooling system.

get those bluetooth diagnostic tool for OBD II then you can get the water temperature for your car

should be plug and play for most car, and the apps cost less than RM20, the bluetooth device itself is RM30+ to RM50

got some brand can suggest? maybe link from lazada ... no idea hows this OBD II work.. but hey.. thanks for tips..

i bought mine from lelong.my https://www.lelong.com.my/elm327-obd-advanc...9-05-Sale-P.htm, and it works fine for me, last time i even use it to clear error code on my friend's car

LYN garage sales should have someone selling too

What is your car that don't have temp gauge ?
I know some lower range models of some brands might not have it.

my neighbor bought a bezza... when i saw the hud panel.. no temp gauge but do a have an indicator.. what a bonkers design ..

It's how auto manufacturer cut cost.... e.g assume RM 5 gauge cost x 500,000 units = 2.5 million saved, not to mention the logistics and inventory management cost saved.

Plus most average motorist don't even pay attention to it.
