Once you have installed your radiator you will be reqired to bleed the cooling system.
If you have never carried out this procedure before then it may be a little tricky.
Air locks form by air getting trapped in an area where there is a high spot in which is, is almost, or is above that of where the radiator is situated.
The best way to bleed the system so that you are fully confident that the air is pretty much completely out of the system, is to disconnect any coolant pipe that runs to your throttle body, given that it is heated ofcourse.
You must then fabricate a stand pipe, which is quite easily made out of a 1.25ltr bottle, which you then apple electrical tape around the mouth of the bottle until it is a fairly secure fit into the radiator mouth.
You must then crimp your overflow feed line so that your coolant does not flow into this and fill it up.
Now that the coolant pipe is off of your throttle body, place the bottle in the radiator and fill it as far as you can with your 50/50 pre mix of coolant, any air that is trapped in the cylinder head will now be forced out of these pipes due to the pessure created by the stand pipe.
Once there is no more air being emitted from these pipes, it is then safe to connect up the pipe back up to your throttle body, add more coolant pre mix to the stand pipe and then start your engine.
Any air that is left in your cooling system will the rise to the surface of the coolant in the stand pipe until your thermo fans cut in, or your thermostat opens(if you have a clutch fan).
Once you are confident that there is no more air within your cooling system, then stand back, remove the stand pipe, let the rest of the coolant drain onto the floor, then put your radiator cap back on then clean up your mess.
Sorry for the long message but I am sure this process will be beneficial to alot of people.
