Super4 overheating problem

[skateboy]

is it sludge?

[200sx]

i was told by ah chong today that if ur thermostat or cap spoil, just touch the radiator abit and the engine fins abit, they should have the same temperature. if radiator is alot cooler then no coolant is in the radiator aka thermostat valve spoil or very low on coolant.

is it sludge?

 

Nope..not sludge.Forgot what they call it.

[skateboy]

after the coolant was used for a period of time, it form sludgish. when flushing the coolant, can c but not alot. if alot of sludge, then jia lat already.

 

do check out wat they call it leh... would like to know as well...

[JbAtRaCeR]

Regardless of the mixture of the coolant or the type of antifreeze used,some lime,rust,and scale will always build in the cooling system.Changes in the engine temperature cause the parts to expand and contract and some of these deposits become suspended in the coolant .Coolant becomes contaminated,deposits will collect near narrow passage,making is narrower thus further the effectiveness of the cooling system.

 

I think we can call it sludge.

 

Deposits can also come from radiator hoses.Radiator hoses begins to deteriorate from the inside ,pieces of these will circulate through the system till it find a place to settle.Its mostly near the radiator core.Bulging or cracking is the signs of failure.Recommend to change those hoses every 3 or 4 yrs.

i think u need a full overhaul

My bike 5 yrs old liao never change coolant bf, yesterday flush and changed as recommended by the mech...however aft i rode it for ten mins away the temp lights up, which i never saw it aft i bought this bike for 2 yrs! immedate return to shop, i complain so the boss came out and help. He opened the cap and topped in some more coolant, i saw lot of air come out from the reservior and looks like boiling it....i think he topped up at least another half a liter in, then tell me s4 cooling system got very small hole and always like to trap air inside and very difficult to fill coolant in and bla bla, but he said even the light on stll ok cos it's the air caused it but water still there, i am not sure on this, any one got experience on this? and aft that i rode back quite ok the light never up, but i do feel my engine got a bit hotter than before leh, can feel quit hot on my knees

It means that air is present inside the cooling system.Once the air is is gone,you dont have the problem anymore.Actually by right,after flushing and adding new coolant,the engine needs to be run to its running temperature.Just to let the air trapped inside the cooling system to expand and escape.

 

Engine a bit hotter than before means that the coolant is doing its job,carrying the heat from the engine parts and to the radiator,where the heat is tranferred to the air.

So if still got some air inside how ah, cos i saw him releast the air from the radiator cap, fill and wait and fill again.....like that needs to take out tank very troublesome, any indication that all air had been chased out? Thanks

[JbAtRaCeR]

Indication hmm...If the temp light stops lighting up,then i think its ok. But just check the reserve coolant tank from time to time..

[skateboy]

if got air means the coolant system not bled properly. one way is to leave the bike overnight, then morning, open the radiator cap, if the coolant is full, its ok. if not full, top until full. the coolant tank, top abit more just so that when the coolant main system do not have enough coolant, it will draw from the coolant tank.

 

n if coolant heats up fast, it shd oso cool down fast.

[FY]

thanks for t info, got to check it out few days later, anyway the boss do ask me to check the coolant reservor aft 2 weeks and go back to top up if it drops....t mechanic didn't do a good job, however he do "prove" to me that my overheating sensor and light is working, haha

[phatmonsta]

HI bros i'm riding ver s.When u guys saying reserve coolant tank.R u refering to the coolant tank on the right sideboard?Mine almost empty oredy. But so far temp lite nvr lite up.Gets pretty hot sometimes n fans kicks in.

[ahboy_ahboy]

so many problems -.-

Almost empty...wah..you can top it up or flush and get new coolant into the system. Bought my spec3 jun this year and juz 3 weeks riding the coolant in the tank also drops,looks like even in the factory they dont bleed the system properly.Maybe not much time as there's many2 bikes on the production line.

[phatmonsta]

The coolant in my reserve tank is like pale green in colour.Can i juz buy any coolant off the shelve and top up? or need to be the same?

[JbAtRaCeR]

Get the green one.

[ahboy_ahboy]

omg today i went cte to vivo city and my temp light came out and i was so scare it burnt the whole bike and after i reach there rest a while and it went blank again what happen?? how come on the way go will light come back ride 100+km continuous and wont light =\

[phatmonsta]

Get the green one.

 

 

Ok noted. what brand of coolant is green colour? Issit putoline one?

[JbAtRaCeR]

Not sure what brand but just look out for ethylene glycol-based one.

[ahboy_ahboy]

i just went change my coolent at $40 + flushing using engine ice coolent

when u encounter slow traffic, the coolant circulating is not being cooled by the radiator bcos when u go slow, the cooling is minimum but when u cruise at higher speed like 90 or 100km/h, the cooling is ideal.

 

in simple terms, slow speed = poor cooling. fast speed = ideal cooling. n its the air flow when u ride that does the cooling. that is y some riders install a switch to manual ON the fan so that the cooling system wun overheat as they can use the radiator fan as n when they deem required.

[biting_point]

if you have a temp meter, cruising at 90kph temp using EngineIce is at 87degree during day, 85 during night..

 

yet to try others..

[ahboy_ahboy]

temp meteR? not all shop got sell right =\ i saw in mustafa 37 or 34 dollars old tyoe "auto guage"

[gunshead]

hello

 

I am so afraid by hearing this problem.

Where can i Buy temp gauge meter something like voltmeter for super 4 Version S.
