Running Temp

[83golf]

Hi guys i just got my car back on the rd but it seems to be running hot.
i have the gti consol and gages installed and it reads just under 100..
is this right? its been so long since its been on the rd i cant remember what temp it use to run at.
any help would be great thanks

I'm sure someone will correct me but but i do believe the fan turns on at 95, so i'd assume 100 is fine, but would be safer if the fan were too turn on a bit earlier to avoid it reaching 100.

Mine turn on at about 85

Stock thermostat is 87°, that's the temp your motor should run at.

Stock fan switch comes on around 90° - 95 °

I put a new thermo in when I rebuilt it. could it be the wrong one and causing it to run so hot?
