Still running hot with new radiator

[newbie78]

So I finally got my new radiator a Spectra and I'm happy no leaks! but now it still runs hot about 220+ The needle goes to about 3 little lines above the 210 mark but back down to 210-215. Never gets under 210.

I am ordering a new ac delco water pump and replacing the coolant temp sensor and sender. I got a new radiator cap and Stant superstat thermostat too and it doesn't change anything.

How do i know if air is in the system?


Also another thing I NEED to do is change the ignition lock cylinder it's getting worse where I can't turn the key on. Takes a couple mins of fumbling with the key to get it to turn.

I'm ordering an Acdelco replacement for $20 but it says it needs programming at the dealer? Anyone have a right up on how to do this and does it need programming?

It's a 1997 chevy tahoe 5.7

thanks

As far as the overheating goes did you "burp" the system of Air when your first ran it?

Can you explain how to do that? And if I didn't do it right the first time I ran it how can I burp it now?

thanks

Forgive me about being lazy to type but I haven't had much sleep today , as for your Ignition key , I may be wrong but I think you do intact have to get it programmed at a dealership (NOT SURE) hopefully someone chimes in and backs me up or calls me out on it .

thanks I hear you on the sleep part lol

It's weird I have burning hot heat to the point my damn shoe feels like it's going to melt if I dont move my foot. I don't think i have air in the system if I have the hot of heat.

I will see what happens after i replace the water pump and temp sensor and sender. Gotta drain all this coolant out in a week anyway to install this stuff.
