Typically, you should not have to change the radiator coolant unless it changes color.

What happens to the coolant when it's "too late"? Can explain?

older the coolant, the coolant becomes more acidic. too old the coolant, it will rust out your car internals, radiator, thermostat, coolant hoses.
Unfortunately this one only measures the anti-freeze power of the coolant, it cant detect the pH value of the coolant, I suppose you could use those pH testing strips to see if the coolant is too acidic.

If your coolant is made with OAT, it doesn't turn acidic.

And the best way of knowing when to change the coolant, is indeed, the color change.

Coolant can break down and loose effectiveness. Keep in mind what coolant does,

- raise boiling temp (So water does not expand and cause too much pressure in cooling system)

- corrosion inhibitor (Different metal like aluminium and steel does not like each other. Google for battery corrosion- This has nothing to do with battery but science)

- lubrication for water pumps (If rust do get into water, it becomes sanding agent and coagulant. It could build up in rubber seals drying it out and wear out water pump seals.)

I think for the last 2 you will be able to see the coolant change color.

I wonder honda type 2 coolant is what type. OAT?

Best read the owner's manual.

Hmmm. Not sure whether that’s really true or not. Scotty k says even hoat based Toyota gets acidic.

at 1:20, he checks the coolant pH with a test strip.


About the color change, my p2 coolant from factory day one is close to five years and still looks the same. Factory manual says to change every 2 years or 40 k( my is 120k). I’m not going to chance it and going to replace it soon. Who knows, maybe OAT based coolants trait a very long time to change color?

Depending on what type of coolant you have in there I suppose. No coolant lasts forever, but topping up coolant is something we shouldn't have to worry about. If you have to top up coolant, it usually means there's a leak somewhere. Sadly, in msia, people don't pay heed to such thing. Even when it comes to engine oil viscosity you can see mechanics blur blur on what the numbers mean. If you factory manual says to change every 2 years or 40k km, then it's best to do so, especially if they will void your warranty. Coolant is not that expensive anyway, and changing it every 2 years is nothing compared to changing engine oil every 4 months.
