Cold Finger

Do It Yourself: Yes
Difficulty: Easy

In my last entry, I did mentioned that my temperature reading is bit off and giving me -10 degree on optimal engine operating temperature.

After some reading and info gathering, I managed to narrow down to two factors (mechanical) that will contribute to this error. Firstly, it may due to worn out needle which cost a lot to repair (if replacing the whole meter cluster) or a bit messy if I need to DIY to fix the needle back to original position. Secondly, it may be an issue with the thermostat which is easier to fix but may cost in between with the first two options. I chose the second option.

Here are the other things needed to do this DIY. Total cost is on the bill minus the wipers.

The result was expected, my lion is getting back its own temperature. Now the needle is hovering between 88 – 92 degrees and sometime it moves to 92 depending on the engine stress.


The normal operating temperature is back!The normal operating temperature is back!

  1. Hi … saya tertarik dengan website bug206 ini kerana byk imformasi dan ilmu yang berguna untuk dijadikan panduan. Baru-baru ini anak saya telah membeli Naza bestari 206 terpakai dan saya dapati suhu kepanasan enjin nya sekitar 90 darjah celsius dan mencecah 95 darjah sekiranya menggunakan penghawa dingin. Adakah keadaan ini normal atau menunjukkan sistem penyejukkan kereta tersebut bermasalah. Sekian yerima kasih.
