So far eto na ang ginawa:

- Jumpered radiator fan
- Thermostat removed
- Radiator cleaning

Chineck ko wala namang leaks, full naman ang coolant kahit mataas na ang temp (3/4 of gauge). OK naman ang auxillary fan, A/C malamig.

Pinatingin ko na sa iba't-ibang shop, medyo iba ang mga opinyion nila, yung isa sa sabi thermoswitch/thermostat daw kelangn ibalik then irewire sa original yung fan, yung isa naman sabi baka daw gasket no need daw ibalik thermostat. Help naman po.

Thanks
dirty / clogged radiator...

during start / stop driving. water is circulating inside the radiator but due to dirt and its starting to clog. heat transfer is suffering. rememeber coolant is cooled through heat transfer between air and coolant sa radiator, kahit ok ang fan... the moment you drive at cruising speed and temperature reverts to normal it is because of the increased amount of air forced into the rad fins during cruising speeds thus offsetting the poor heat transfer inside the radiator during start / stop driving where only the fan is inducing air through the radiator. hope this helps...
