Engine still steam after new radiator?

1984 CJ7, just punctured a whole in my radiator, bought a new one from autozone http://http://www.autozone.com/autoz...6165_266441_0_ put it on today, drives okay engine doesnt get super super hot but will steam.

Only thing i can think of/ noticed was that the radiator cap doesnt seem to fit very tight like it should.

Would that possibly be why it is steaming?

Anyone else have any suggestions or thoughts as what it could be?

Thanks a bunch
NIck

replace the cap then run to operating temp, let it cool, then top off the system. repeat until you've got all the air out of the system.

Sounds good, one problem though... lol

temp gauge doesnt work, replaced the temp sensor and still doesnt work, my assumption would be electrical which i havent gotten around to doing

Also the genius i bought it from DID NOT have the surge tank connected to the radiator, he was just running the radiator without the coolant surge tank,
not sure why, i looked at it and i feel stupid saying this, but for the life of me i cannot figure out how the darn thing even connects to the radiator, hose from radiator doesnt fit anywhere on tank, i am pretty confused at this point.

Was running fine without the tank being connected before though.

Thoughts?

Was the temp gauge working before?

when you pull the cap can you see fluid? Also get a new cap if its not seated firmly.

Chech the ground on the back of the temp gauge. As for the rad not sure why its steaming since iys new. Just make sure to give it a good burp and all the air is out of there. you may wsnt to measure the specific gravity make sure you have the correct antifreeze/water ratio.
