If you have an airlock at the top of the rad then water wont flow around the system. Had this with the new rad on my Esprit and I had to bleed it a few times and the Esprit has a factory fitted self bleed kit.
When the car is up to temperature feel the top and bottom of the rad. If you have an airlock then the top will be cooler then the bottom. You have to bleed it and if you dont have a bleed kit then remove the small hose on the top of the right side of the rad when the car is running.
You should hear lots of air rush out then water should run out. Replace the hose and feel the rad again, The top should now be the same temperature as the bottom. If not repeat until it is. Also make sure that when your bleeding the system that the header bottle does not run dry.
After you have done this run it for a few days and then check the water level in the header bottle. As air comes out water goes in and the level drops, so keep it topped up.
