to temp threads?

I've got the 'ol 1990 190E 2.6 back, selling it for Dad. Coolant temp has been fine, running 80-90, with hitting close to 100 in traffic with high outside temps and AC blasting.

Suddenly, it runs at 100-110 ALL the time.

Both electric fans are running properly. I am suspicious it is either the thermostat or high speed fan relay. I watched the "driven" fan, and it never seems to go to "top speed."

Can someone point me to the location of the relay?
