Topping up of coolant

[Phluvcat]

Before I change to actual coolant, was using plain tap water. There was then never a need to top up.

 

Since changing to coolant (me using Toyota red coolant), say once every 5 to 8 weeks will need to top up about 1/3 to 2/5 of the container.

 

Is this normal? No issue for me as I bought the big container of coolant and left it at home.

It's abnormal. It is a closed cooling system. Nothing evaporates. Something is leaking.

Sorry TS highjack your thread....since we are the subject of coolant.....how do I use Redline Water Wetter?

[Gnahp]

your car has a leak

[CrazyPig83]

Confirm + chop leaking....don't on air con before u park...after that park for few hrs and check the floor or radiator fin see if there's any dent and also radiator pipe

Your radiator may have some leakage near hoses (Inlet or outlet radiator hoses) or engine block "eat" water already ! (Due to minor crack along engine block cooling passages & it seepage into cylinder block !) Toyota car hardly "eat" water and do not need so frequent top-up ! MUST perform pressure test using Test Kit by your mechanic !

By the way, after wam up does your engine got some water vapour discharge ?

I do not know if you have leak, but you should never ever use plain water as for coolent. This is madness. You are lucky that the water did not boil inside of your car. If not, maybe you can change engine liao.

What's the charges usually just to test if there's any leakage or water seapage into block or engine.. ?

 

It seems like there's a need to topup once alittle once every 1-2 months or so for my case..

 

I'm purely using Honda Anti-Freeze coolant..

Water can be used as coolant, but the main concern of using that would be rust and lower boiling point (100 deg celcius) and higher freezing point of 0 deg celcius, though freezing is not applicable in sunny singapore. Water, having a lower boiling point may also not be very ideal in carrying heat away from your engine parts to be cooled at the radiator.

 

Some high performance coolants claim to be able to lower the temperature of your engine due to their special mix of chemicals in the coolant that gives it a lower boiling point. Beware of those claims because modern cars have a thermostat that automatically adjusts air fuel mixture to constantly keep the engine at the "desired" temperature.

 

Coolants boil inside your car all the time. Try opening up your evaporator cap after an hours drive and you will get what I mean.

Not a good idea to even try.

If you have good workshop, then it's free or else S$ 10 to S$ 15 for the test (Being laobor).

ummm...I meant the reservoir that I am topping up but it may also mean the same thing.

 

as nowadays I park in a MSCP, I will on and off check the floor...there is no blood on the floor, totally dry apart from water.

 

tomorrow I go check the radiator.

Oh. When the coolant is cold, for instance, overnight, the level will be lower. When it's hot, it will be higher. This is normal.

really apologies for not making my post clear enough. to be frank I forgot about the radiator!!!

 

I will still check my radiator since some bros mentioned about cracked engine block...I have my concern as I redline the engine every now and then.

 

thanks.
