after i broke my old temp sending unit,i got a new one.the old unit was all corroded,but read well on the gauge,it did show cooler than normal,but the fan came on at exactly on "m" on the gauge.to my surprise,the new unit goes well past "m" like 2-3 letters if it had them.so i tried to calibraite[is that how you spell that?] by using resistors from radio shack.friend of mine told me years ago chrysler had a tech bullenton on their gauges flipping out,going way past where they should.they actually suggested using resistors to fix the problem.my s10 did that and the right resistor fixed it. i ended up buying a 99 cent pack of 15ohm-1/2 watt-5%tolerance and 10 ohm.the 15 hardly moved the needle off the blue[at operating temps] the 10 ohm let the needle move between the "n" and the blue.it seems to need a 5 ohm or 2.5 to make it closer.i,ll be returning the 15 ohm and i,ll see if they have the others.let me tell you,it gives you piece of mind not seeing the needle over near the red before the fan comes on! thought you guys might find this interesting
