peeps, patanong naman. weeks after replacing my aux fan, pansin ko that the temp went up and beyond the 3/4ths mark, even only after about 10-15 minutes of driving with the aircon on. with the aircon off, the temperature immediately drops to below the halfway mark; even after an hour of driving with some stop-go traffic, temperature seems to be stable.

some other facts:
-- aux fan seems strong, and engages quite consistently;
-- just replaced the radiator with fresh water/coolant mix;
-- there doesn't seem to be any water/coolant loss, even after extended driving, and multiple incidences of reaching above and beyond the 3/4ths mark.


i'm starting to suspect that it's the thermostat.

Waddya think?
