Question about Opel Cars & Trucks
My Opel does NOT have radiator cap. So question is : How to do it?
Find the highest hose and loosen of the clamp to release the air from the system
many have a bleed screw at that point as well
have a compression test done and have a coolant pressure test done to check for leaks

First check for the rad fan working. It could be the Fan relay, bad ground connection or coolant temp sensor (commands the fan relay). If not, check for little tiny bubbles in the coolant. Do this by running the vehicle with the rad cap off. Make sure there is no pressure in the cooling system first or you will get burned (squeeze rad hose, should be cool and easy to squeeze). Look into the top of the rad and watch for these tiny little bubbles. If they are present, you will need a head gasket.

cool air and overheating point to low coolant level. Do you have a bleeder valve near the thermostat? You may have air trapped in the system. If no air trapped, the radiator may be plugged up not allowing proper circulation of coolant.
