Trying to bleed a radiator that's cold at the top, hot at the bottom. However it doesnt have a valve like a normal radiator.

There must be a union connection that joins the radiator to the piping, open it ever so slightly and make sure you can contain the water with a suitable container, be careful of the temperature. The proper way is to bleed the entire system.

Strange question really. Do you mean an air release pip? Its not a valve at all. Assuming you don't know, use a radiator key in the top right or left corner of the radiator and turn anticlockwise until either air or water is released. Keep letting the air out till water appears. If the radiator still is cold in places, take the whole thing off and flush through to clear any debris which may be blocking the flow.
In the event there is no air release pip which is unlikely, then you will have to drain down the radiator and then get obtain a pip and install it, get it from a plumbers shop. Then you can release the air. No other way.

turn both the vaves off at the base of the radiator at the top you will find a plug 1/2" .slowly remove it making sure you have a cloth incase any water comes out replace it with a bleed plug and valve from any good plumbers merchants turn back on the radiator valves to the original settings and then bleed as normal you can now bleed the rad at any time you want to

You probably do have an air release valve,unless it has been sheered off in the past. on some makes, the valve is behind the radiator,this has caught me out in the past.Run your fingers behind the top of the rad at each end(sometimes they even have a plastic cover that pulls off to reveal the air release). There is no point in loosening unions etc as advised in previous posts unless they are at the top of the radiator(unlikely). Good luck!

Does your auto have an engine block drain?
Maybe the radiator has a drain plug instead of the traditional drain valve?
Just thoughts.

Try taking off your bottom rad hose, this will drain the fastest way without a bleeder valve. Required a screw driver or a pair of plyers.

The answers are good but do switch off the system before you bleed it so it is not pressurised by the pump
