Help: Overheating Problem

**zerocool1799** · July 21st, 2009 02:00 PM

Mga sir, ask lang ako ng opinion yung car ko kase 97 corolla gli napansin ko nataas yung temperature habang idle or natatraffic.

Then kahapon napansin ko na yung aux fan dun sa may radiator natakbo lang pag naka on yung aircon tapos parang mabagal lang sya tapos titigil ulit. I know para sya automatic kaso ayun nga for the mean time ang ginawa ko eh tinanggal ko muna sa thermostat sensor ba yun yung plug nung sa AUX fan para continious sya natakbo. Ok naman sya nde na nanataas yung temperature nasa kalahati na lang unlike nung last time para na syang nakulo.

Ang question ko do i need to replace the thermostat sensor or need ko pacheck muna wirings ko? Nagtataka kase ako pag naka aircon lang natakbo tapos mahina pa.. pero nung ni disconnect ko sya dun sa thermostat sensor ang tulin ng takbo.

Thanks in advance.

Bro just want to ask diba you said you took off the connectors coming from the fan to the thermistor sensor and you just connect it directly to each other and your fan spunned fast. Maybe you need to use a relay because a thermistor sensor ould only allow little current to pass onto it thats why your fan turned but just slowly. just my opinion.

Thanks for the reply.

Yung sensor kse yung nakakabit sa engine then may plug lang sya na nakaconnect sa fan after ko sya unplugged constant na natakbo yung fan. Unlike before na tuwing may aircon lang.

time to replace the sensor, it's about to give up kaya likely erratic ang ikot ng fan.

Hi Mga sir,

Hmm. . .there is a possibility that engine would overheat when you remove fan shourd.
Its major function is channel the air for smooth air flow for greater cooling.

less effective ang fan pag wala ang shroud. at kung wala yung shroud pwedeng umiikot lang dun sa engine compartment yung hangin so bawas ang hangin na nahihigop ng fan na dumadaan sa radiator.
