hi sifus out there...

wanna know if what happen to my ride was normal...

i was driving my ride & caught up with traffic congestion, so the temperature gauge shows this....(it happened too if i park my car idle with AC on) :



when the car started to roll, then the meter will stay exactly in the middle but will fall down under the middle mark during the nite (cooler at nite?)

hope someone can share an idea here? Abnomal?

check ur coolant lvl & the color of the coolant whether its murky or coolantcolored.

sounds like the thermostat needs changing .

happened to me b4.
flushed the coolant all out , replace new thermostat & new toyotacoolant.

dont quote me on this

tq...the coolant is brilliant green with crystal clear view....???

anyway, the thermostat will cause engine to over heat rite?

what type of coolant u used bro?

dono leh...inherited from previous owner....but i suppose the coolant is of right type la coz it was serviced by Ingress Auto at Mutiara Damansara...

i could be wrong on this also ,
a properly workign termostat allow coolant to flow thru the engine when the engine is at operating temperature . if the termostat is faulty , the engine would not allowed to be cool as it still thinks that the engine temp is cold or below warm-ed up temp . Once the engine reaches its operating temperature , the thermostat opens. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions.

mine is changed almost every service, that's what i heard should be done regulary .

hope this helps.
btw try toyota coolant , red wine in color , its quite good. rm20 per bottle 1litre.

AB got their own long life coolant...selling cheap in SG but expensive at AB...dark blue in color...so far all my JB gang use it n say GREAT....maintain at half or slighly bellow half if the radiator is in brand new or great condition....u should try it out!!!

mmm my car the same problem also.....heats up when aircond is on in traffic....maybe its time to change thermostat...but even on my old engine with new thermo it stilll heats up!

from my experience..
what i did;

flush the cooling system
change the fan clutch

now, tak lebih separuh pun even with ac on masa jam
mind you that i only pour in tap water

haziq , tumpang tanye ,
how much is the clutch fan ..for m20b20
think mine is due soon

Mine will never reached half. The max is the 2nd level. The thermostat maybe is the culprit. Better check bro. U wont want ur NEW ride overheated rite?

bro, change to a lower temp thermostat and then flush the radiator with 2 bottles of toyota coolant. kao tim

TQ BROS for the valuable advises, will try to sort it out first by changing the thermostat....

last nite, traffic jam downtown has caused the temperatyre to rise passed the middle mark, i guess i m pretty bz with preventive maintainence this weekend....AFM, ICV, Thermostat....etc etc....
