top up is 1 thing. but ur radiator got water inside in the first place?ur radiator cap is under ur tank on the front right side...

[carbine]

its ok if it nv drops below the LOW mark

Bros,

 

my bike only leaked that once and only once and i din see any more leaking .....i inspected once again and i think i found the source of the leak, it's from the pipe that is above the pump..the tightening screw-like thingy that is fastening the pipe to the pump has sorta came loose as i was able to tighten it a fair bit ........so i came up with the conclusion that is the cause of it. There's no possibility that the pipe has hardened cos when i pressed on it a few times, the tensile strength still seems to be there ..............

 

to add on to my beliefs, i spotted tiny traces of hardened coolant hear the opening of the pipe , so taht's where the leak has emerged from .My bike doesn't overheat alot, fan's working and the reservoir level is maintained consistently. The last top-up was in feb and it's still in almost the same level ........

 

thanks for all ur help bros

eh i am riding a spec 2 but wheres the radiator cap ar???

[cookie_monster]

actually if e top block crack(minor) or top gasket wear-off will also cause e coolant to b dry off cause it leak in e top block..... when combustion tak place in e block, e high heat generated will eventually dry e coolant tat travel thru it......

 

better do something quick..... if ur eo n coolant mixed ur engine

[FunkyChicken]

if it leaks again, pls send ur bike to reliable bike shop to inspect coz the coolant motor pump is a small price to replace when faulty or leak ( usually due to faulty motor not gasket). coz if ur coolant pump doesnt circulate thru the engine, ur pocket will burn a big hole.

 

my dad's pjct big happened once, but discovered it hence send for replacement asap.

RECENTLY MY VEERSION S S4 FACES THIS PROBLEM. i DISCOVERED THAT THE COOLANT IS VIRTUALLY LEAKING FROM THE ENGINE BLOCK. APPRAENTLY THERE IS NO CRACK BUT I SENSE SOMETHING IS NOT RIGHT. I WENT TO 10 SHOPS AND WAS TOLD THAT THE BIKE HAS A MAJOR PROBLEM. THEY NEED TO SERVICE THE TOP BLOCK AND IT COST PRACTICALLY AROUND $1000/- OVER.. IS THIS LOGICAL OR THE SHOPS ARE JUST TRYING TO COMMIY DAYLIGHT ROBBERY. I NEED UR EXPERT OPINIONS URGENTLY... ANYONE KNOWS. IF YES, WHERE CAN I GO AND GET IT DONE AT A MUCH2 CHEAPER PRICE...

a pic of it will helps more.....for such issue if coolant really leaking or ozzing out from there is not a small problem...so do take a pic to see where exact the coolant is leaking...

[saico]

i really hope those bro's out there can giv some advices, cos my fren who is riding a version s, has some sort of this problem too..coolant leaking n stuffs..

[episode2]

for previously my version S also has a leak but its from the coolant hose connected to the thermastat that area...seems like it stain till the block area so at first i think its leaking from the engine block area..thats y i prefer a pix and another confirmation from the problem 1st.Cfm when u see certain amount of coolant ozzing out from that particular area... just incase we might give the wrong advise/s ..do a double check first...

[mnemonic]

First go check all your coolant hoses..if non is leaking...I tell u wat has happen to your bike...Your top gasket is damaged and coolant is entering your engine system...will mix with your engine oil in your engine and if you don't do sumthing quick about that....you can say bye bye to your s4.... ..NO joke bro...

[HondaSuperFourHSF]

Yes gasket leaking.. Here is some of the knowledge you must have.

Coolant is to convey heat from your engine to the radiator to be cool off or to convey heat away to other parts.

Coolant is all around the engine area. So how to stop water from entering the engine compartment is by gasket. So metal and metal can be seal together properly. Now is that the gasket is damage maybe due to overheat of engine or you can say wear and tear. Proper maintenance of cooling part will help to prolong the life of gasket.

There might be others fault like crack in the engine block etc. If the leak happen to be at the gasket area then is only gasket damage if the leak is come where else you will need to overhual the engine and maybe seal off the leak. But then it is only temporary as once there is a leak there will alway be another as our engine block is done by moulding unless that you purchase the whole engine block else it will leak again.

 

Hope that i have solve your problem and increase your knowledge in engine.

 

BTW it will not be a damage valve or piston damage.

Have you check the coolant pipe line... mine oso same found out it pipeline (rubber) spoilt liao... after 10 yrs of riding

[louis ler]

hi guys,

 

i have the same problem.

 

appearantly coolant is ozing out from the side of the block, there is a small hole on both sides.

 

check with few machanic, they told me 2 just keep topping u my coolant water, thats all, coz itz damn ex 2 repair..

[ArsenalBoi]

yes must do. either gasket spoil and got leak or block crack

[Tyrian]

my version s oso..

 

its a common problem among all the verS.. i bought it 2nd hand so i guess the previous owner/s didn't maintain the cooling system properly..

 

nw i oso can't be bothered to top up.. as long as the temp light is not on, u r on the safe side..

[LordCani]

As far as i know, version S has this common problem... coolant leaking from the 2 holes of the engine.. i saw a version S at K&T facing the same problem and clifford told me the bike will need to go for top overhaul to rectify the problem once and for all... ive seen in forum some pple faced the same problem and went to planet to troubleshoot, ah chong added some kind of chemicals into the cooling system and the leak stop. Im not very sure abt this but i hope it will help u... U can try going Planet cause i personally think ah chong is good... Ride safe~
