Purging Coolant System

We pour coolant in to the coolant system, in order to start the engine I kept the engine running for 4 to 5 minutes , I saw that in the dash board the temperature needle did not move at all. this may be related to the purge. Also I need to be sure that coolant fans will run, when the vehicle need it. So I maybe thinking that there maybe be air locked inside the coolant system. So I would like to bleed the system. There should be a bleed screw or valve in order to purge the air out of the coolant system. That what I am looking for. If there isn't, is there a proper procedure in purging the coolant system.

The bleed valve, not really a screw is located on the thermostat tower. It is the large screw cap and the highest point in the cooling system. It would be loosended, not removed, to bleed any air, then closed back to a prescribed torque setting. These a common leakers so it is seldom used for its intended purpose. If you want to ensure it doesn't leak, and before you pressurize the system, remove the cap and wrap the threads with teflon tape, then the cap will seal properly at the proper torque.

Wise words on tightening the cap - Every time I've run across a cracked cap it is because someone cranked down on it with dry threads, usually trying to stop a leak, and far beyond the torque spec. It is going to crack if overtightened and very lucky if it doesn't.

This excellent tutorial from MrTexasDan describes the coolant plug on the later XKR's in step 8 (mine is just like this - I followed Dan's advice when changing my thermostat)
