Temperature Issue

[Edward_Lee]

Suggest you check your thermostat. Could be jammed permanantly open.

Or better check your meter - maybe the meter itself is spoilt.

If it's a thermostat issue better get is solved ASAP cuz running at non-optimal temps means your engine oil is not lubricating enough and that means your internals is not getting proper lubrication hence higher wear and tear

Thx for your suggestion bro Izso, i understand the importance of optimal operating temperature and as well the optimal properties of lubricating oil.

I personally tested on both thermostat (old n new), both opens almost the same moment n shuts off well. The sensor it self i've cross test with another 1 with the same kind (value). Abit give up on looking for the cause .......

Maybe the coolant you using is too 'powderfool'

Aiya, if it's lower than normal it might just mean your engine isn't running as hot as it used to. Better cooling, better engine oil used and better air flow result is lower water temp? It does happen you know. Or as suggested, your coolant works too well!

I don't know is it the best la ......
Those liquid lubrication product i'm using just normal ordinary Toyota Coolant of 50 : 50 ratio with purified RO water , 5W/30 Semi Syn , Iridium plugs , K&N tats all :hmmmm2::hmmmm2:

Oh I forgot the last possibility..... is your meter spoilt?

Next coming plan, install an aftermarket temp gauge and temp sensor ...... hahaha

No need buy replica la... buy those with decent brand atleast got warranty.
The meter normally wont give you problem but most of the time is the sensor 'kong' even Defi are also same.
