it's been well established alredy that the OEM dash temp is highly non-linear and gives very misleading information on the temp of your engine (see for ex the great info by our friends here who generated curves of resistance vs temp and discussed this before).
Well, now that I've rigged a coolant temp probe, I wanted to see how bad this gauge's indications really are in my case.
Here is what I saw:
Needle at lowest position : engine temp 98 F
needle at "0" / 107
1/8 : 112F
1/4 : 117F
3/8 : 125F
1/2 : 132 - 221F with no change seen in needle position over that range.
Didn't go above 221F.
This is eyeballing the positions of course.
I didn't think it would be this weird.
What on Earth were they thinking?
