hi..neeed advises. My car temp is usually between L and H at the dashboard. But recent weeks,realise that the temp can go up to almost H intermitently. For instance, it may be at H when i am stopping at traffic light, once i move off, it does back to between L & H again...This happens intermittently. I though if temp is High..it should remain high for quite some time?

Any bro can advise? Is the water temp really high or is there a sensor problem somewhere?

your FAN working hard enough??... check this basic out first bah
Second, u may have a bad flowing system for your cooling system. Get them serviced soon and also check out the thermostat. Dun stress to level H cos sooner the head gasket will worn out. Watch out for jam

At stop, off the a/c if possible to lighten the load. Trick for stopping from far, avoid engine brake, use free gear to roll and apply smooth braking. Pls check for traffic safety condition if u dunno the car well. Ignore this paragraph if u cant understand. more important is drive safe.

fan is blowing all the time..bypassed the fan switch.How to check the thermostat?

First, about the fan, it blowing but doesnt mean the motor is strong enough. if u hav a friend of same ride, compare them.

Next, dun skip this check. it about bad cooling system that might cause u the problem. hav mech to check hose by dismantle (change if they are harden, change if the rubber wall is cover by thick subsidies). When they took out the rubber hose, check out the thermostat along the way. dismantle the radiator and flush it by chemical. Last, do top up with new coolant.

No matter how, u still need to go see mech unless u are familiar with DIY yourself.

if you're not experiencing any coolant loss then 99.9% chances are your radiator is choked... go for chemical wash..

First..

Check ur cooling sys first eg. Radiator, thermostat, blower etc.
Btw, bypassing ur motor blower for the radiator fan which makes
it on everytime lessens its lifespan.. I wont recomend it.. Theres
a purpose why it has a magnetic switch w/c turns on everytime
it reaches certain temp.. Neway have the thermo switch checked
on thermostat might be corroded.. Then lastly check ur radiator
maybe the cooling rows are clogged better flush it or by oem or
aftermarket ones..

Secondly..

After checking all the above.. And problem still exist.. Have the
connector at the water temp sensor cleaned maybe its corroded
and doesnt throw proper sigNal to the ecu making ur temp guage
up n down..

ok.thanks for all the advise bros! i also realised needle in my water temp gauge now not moving...maybe the water temp sensor really got problem..i think most probably is water temp sensor prob or choked radiator system

HTH

Any updates bro??

head gasket got problem. radiator reserve tank got water but main tank no coolant..I didnt realise as i only refill reserve tank. I though both tank are linked and refill the reserve one will do

You must refill both.... Radiator is more important.... Must have water in it...
