Recently, through the help of this forum, I also asked my mechanic to put back the thermostat and thermoswitch on my every van (old cat's eye model).
I bought a new thermostat (Php360) and a thermoswitch (Php450). The thermoswitch's brand is Circuit and it said "For Suzuki Super Carry F6A". I'm in Cebu Philippines by the way.
My mechanic then installed both and then he tested it by turning on the engine. The temp gauge now goes to middle in a very short amount of time, probably less than a minute. Before, it would take 3-5 minutes to get to the middle on a cold morning.
But then the radiator fan wouldn't turn on. So called me and said, he will short the wire back because the fan wouldn't turn on when the gauge goes slightly above middle.
I went to him and I insisted that we observe until the gauge went past the dark marker going to H. He was hesitant but I still insisted
About 1 o'clock position, the fan turned on, brought the gauge back to the middle and turned off. I was skeptical why the delay of the fan. It didn't reach the dark marker but it was closer.
I drove the van around and it stays that way. Gauge is at the middle, then it goes 1 o'clock position, fan turned on and gauge back to the middle.
Engine runs good. I am just not sure if this is normal for us here in the PH (gauge at 1 o'clock).
What do guys think?
