When warmed up, the needle in the temperature gauge of my 92 400E always points to the white mark between 80 C and 120 C, what temperature is it showing? 90 or 100.

I put in an aftermarket 90C thermostat since winter came, that's why its temperature is higher than normal, I want to make sure it's 90, otherwise I will remove the crappy aftermarket one.

Thanks.
