Question : I OWN a 2000 Waja and the problem is when I drive at
night, the temperature needle will rise whenever I stop
either at the traffic light or for a rest
when driving long distance.
When it happened, I had to switch
off the air-cond for the temperature to come down.
I had installed everything the mechanic recommended but it still happened.
Most cars today run two cooling fans,
one for the cooling system and the other
that comes on when the air-cond compressor comes on.
Check if both your fans are working.
Sometimes only one is working and
that will cause the temperature to rise
when idling or stationary.
It is strange that you have the problem
only during the night and if this is so, is
the fan working properly during the day.
If this is happening, you should check
where the fan has been connected to.
