Kindly let me know how to check the radiator fan working as I noticed that even temprature gage needle at half point my fan dose not start.

Secondly I need to know which computer Protocol it has to read the DTC code my ODB conector has four wires only one at pin7 and one at pin4 one at pin 5 and one at pin 16. I ordered for allinone OBD tool recently and hope it will conector. The launch x341 do conect but dose not read dtc code only give the raw data.

Your fan should not come on until the sensor reaches 96 degrees C or so. The fan is more of an emergency cooling device that should never come on unless idling or driving in slow city traffic. It is normal for an electric fan to not come on until the temp gauge is well above the half way mark.

@ shadownseiko: Sir, what's the normal operating temperature of the multicabs? I have a scrum 660cc, 12V, 5-speed tranny & a single array tube but wide radiator. My analog temperature indicator reaches halfway or 50% (always) even if I only travel @ about 3Km.

But i'm glad my car survived the 220+Km travel from Cebu North (Medellin) to Cebu South(Badian to Kawasan Falls) with my fellow engrs & family. The cars temperature reaches 80-90% of the temp meter on uphills and back to middle @ downhill to plain with average run of 70-80Km/hr (A/C Off).
I'm afraid this temp will rise without my attention and observed, my friends suki van's temp. is only reading 25% of the meter throughout the trip with his 2-tube radiator.
Is replacing a single tube radiator to a 2-tube radiator solve the problem?
Regards.
Need help. TIA :)

My fan would only turn on at idle up to slow moving traffic.. for speeds 50kph and up, I don't notice the fan to come on..

It would also turn on ONLY when the temp gauge reaches about 3/4, then it turns on and it gets back to 1/2 and afterwards, the fan turns itself off.

The 3/4 temp is a bit scary at times especially if it stays there a bit longer (like a slow moving traffic, there is slow air but not enough) but I am getting the hang of it.

@shadownseiko: What do you think of this?

Disclaimer: mine is an F6A 660 van rear engine
