Weird over heating problem

Weird over heating problem this is driving me insane. I installed a new radiator. Fill it up with water and it gets to 210 and stays there. Then 5-8 minutes later water comes boiling out of the over flow BUT the temp gauge still reads 210. Now2 weeks ago my temp gauge worked fine because I saw it go way up and thats why I replaced the radiator. I tried a new radiator cap and that didnt work. I think I got all the air out of it.

Make sure the steam vent tube running to the radiator (right below the cap) is on the nipple below the over flow tube. Over flow goes on the top nipple, steam pipe to the bottom. Er, maybe its the other way around. Ill have to pop the hood and check. But look into that. Ive seen the exact thing happen from having these tubes crossed. The system will build pressure and overwhelm the overflow tank.
Might also want to run a pressure check on the cooling system and make double sure the waterpump isnt leaking or on its way out. If you run a pressure test and you get bubbles in the overflow, switch the tubes.
Hope this helps, Josh.

How did you determine the radiator was bad in the first place?
I would try rebleeding via the crossover tube to see if there is any more air. Then take it from there...

The gauge is not accurate at all so long as the vehicle is at operating temp or slightly higher. You can be from 180-240ish and the darn thing will still be at 210. When it does grossly overheat though, that's when you actually see the gauge move (which is too late because the vehicle's been overheating for quite some time by that point).

I had an overheating problem as well and i didnt bleed the system right the first time
. ....SO like he said bleed the system vis crossover tube and pour the coolant slowly until you have a steady flow of coolant coming out of the tube. That fixed my problem
