My temperature needle raised close to the white mark (11:00 o'clock) when I
drove to up-state two week ago. I have replaced the oem thermostat and bleed
the cooling system. Back flush radiator only, plus cleaning the radiator by
spraying water form back of the radiator toward the front.
So take a test drive, put it in 2nd gear instead of 'D' Everything seems
fine after 20 min. the needle risked again.
The driving belt did not seem slipping either. So what is next? Water pump?
Or suggestion?

TIA,

Kin
