hi, I would let this run with the cap off for 10 minutes then shut it off and let it cool down for at least 20-30 minutes ,this will allow the air to be purged out of the system ,you may have to repeat this a few times ,if you did not have a overheating issue before the radiator replace, ,if you did have a overheating issue or running hot and replaced the radiator because of a leak check to make sure the cooling fans work ,these should come on around 210-225 degrees,make sure they are plugged in and also you can turn on the a/c to check them also,,I am sure that if you did not have a problem before the radiator then just purge the cooling system ,like I stated...guy...

The reason i replace the radiator is because my fan blade broke and put a hole in the radiator..i put a new blade on it...
