oh sorry.. it's water temp

Normally water temp on my car pointing just below from half level, no matter day or night driving. I think your thermostat jammed and always opened.

My previous Silvertop engine also crusing at nearly 1/10 scale, especially early in the morning.
The temp will goes up to 2/5 scale during hot day heavy traffic.
After plug in BT engine, the temp stay at about 2/5 scale, no matter hot or cold day.
I guess this is one of an improvement made for BT engine, to have more stabilize working temp.

IMHO...the dash water temp meter is literally crap...it wont give you any warning until its too late...had a couple unpleasant experience with it...

first time kena when i'm still running 4afe engine...that time radiator cap have a small leak...i dont see any steam coming out...suddenly the meter shot up and engine died...after inspection radiator no water at all...lucky i just drove a few km...top up water and drive back home...

second time kena...almost the same case but this time i have another water temp meter installed...suddenly shot up pass 130 c...but the dash meter still at half the level (which is normal i guess)...immediately stop the car...inspect the engine...the rubber water stopper at the thermostat housing burst...a quick DIY by the road side...top up water and drive back home...

if havent for that another water temp meter...i would drive of like nothing happen and probably kill my engine in the process....

so if you thinking the dash meter is giving you the correct reading...trust me....no it is not...it just show you the "general" reading of your water temp...

Wow...
Thats is new info for me. Is your external water temp give an audible alarm when overheated?

yes its true according to bera. happened to me once in perdana, the water temp meter suddenly shot up to max & car died.
suggest to get external water meter temp as its more accurate.

Yup, it depends where the meter is taking the reading. I remember my old ride takes reading from radiator, but thermostat jam so no hot water going through. Meter still shows cool but engine acting funny as it was getting hotter and hotter. Lucky stop and check if not engine burnt....

not audible...there is an extra option to do it but i dont hook it up yet (cant find the door ajar buzzer)...currently relying on flashing LED if the temp went past preset temp (now set at 120 C)...

Check Radiator clogged? or water pump and/or radiator fan running optimum speed?
