Hello people, vehicle: omega B Built. 99 136 hp , climate, 2.0 l 16 v since my operating temperature in traffic jam or city traffic between 95-102 C commuted yesterday I first renewed the thermostat. Vehicle ran about 7-10 km constant to 95 C. When I wanted to park the Tempaartur rose again to over 100 C, fan then went on and then it fell back to about 97 C. Now I thought to renew the cooling liquid and clean the system. 1. Where is the drain screw for the cooling. medium ?? Does anyone possibly have a sketch ? 2. Do I need a lifting platform ? 3. Does anyone possibly have another idea what the reason for this Tempaartur could have risen ? I ask for your Infe, will slowly become mad with the box
