Topping up water in radiator

[Bluefreud]

hi ,

 

found out that i have to keep topping up water in my radiator everyday, though it's not alot, maybe like 50 ml of water.

 

i found it strange cos last time i only need to top up like once every 2-3 wks.

went for a check, nothing leaking but my mech suggested maybe my radiator cap old already and needs to be changed.

 

also asked abt my water temp gauge cos now water temp very high, ave 100 degrees celsius which i thot also abit strange, then he said might be because my sensor not accurate.

 

hmm.. i dont really know what's wrong. wonder can any one have any suggestions?

the only recent thing that i have done is to change to new knn air filter from old knn-type air filter.

 

thanks.

after u driven, pop open bonnet with the engine running and look.

 

a few type of leak. sometime, the hose leak can see either a stream of hot jet coming fr hose, or steam coming fr hose.

 

otherwise is radiating top pichar.

 

also depend on coolant, if u hv not replace them after 2 years, time to do so, they hv basically lost their properties already. do total flush and go for redline water wetter. pay a bit more.

your radiator might have leak...

When is the last time you change your thermostat? Your thermostat maybe old already and not as effective anymore causing your water temp to raise, thus hot vapour may escape through the radiator cap.

hi,

 

thks.

i have also tried driving and then see but didnt see any leak.

radiator top means the cap?

 

i have just done a coolant flush liao.

at 1st, i thot coolant gone, tat's why did a flush and top up new one, but still the same.

[Bluefreud]

hmm..

thermostat?

i didnt know abt this.

thanks for suggesting.

so i can change myself or go thru my mechanic?

1. internal leak - any white smoke from exhaust?

2. thermostat - can do it yourself, not too hard, but needs some hands-on.

3. radiator cap - maybe it's old and spring not tight enough

4. hose leak - cracked hoses? loose hose clips?

Bro, I think the high chance is the radiator cap. It may be worn off and you are not aware. I think I have a similar case before and after changing it, it sovled the problem. Check the cap youself to confirm.

hi,

 

thanks.

how do i check to know whether the cap is gone liao?

[Bluefreud]

ok, think i will change the cap 1st and then monitor.

thks for ur suggestions.

After driving, immediately open the bonnet and check the cap, see if there is any leaking or hissing sound around. Like one of the bro here mentioned, it can be the radiation rubber tube as well. So just do a thorough inspection that is connected to the radiator.

Is there any brown substance at the mouth of ur radiator?

[Bluefreud]

yah, there is.

i thot tat's the rust.

[Thug]

COuld be dirty stuffs in ur radiator and jam the whole circulation hence temp rises...

Similiar problem with my 16 yrs old civic...

[Bluefreud]

hmm.. but i just did a coolant flush.

so how did u clear the dirty stuff?

mine is 17 years old liao.

I used to encounter a similar issue where the water level dropped and some dried water stains could be seen near the reservoir tank.

 

After changing the thermostat, it solved the problem.

[Thug]

I flushed...i change radiator...same thing going on...

Coz my engine oil is leaking...

So in the end I change the whole damn engine...

Everything solved...

 

Maybe u might wan to check ur engine too?

[Thug]

~yup...thermostat might get stucked and block the coolant from circulation...
