Ok the car over heats to the bar before the H then drops back down to normal then after a few more minutes of driving it goes back up then starts to climb for H. I had a crack in the radiator so i changed it out yesterday for a new one. But it's still overheating. After i shut off the car now i can hear in the radiator like it's sucking??? and bubbles blow into the overflow tank. It's a 89 Ka24e can anyone tell me what's wrong?

try jacking up the front as high as you can, and take off the radiator cap. sounds like you have air in the system.

Or maybe open the breather valve located next to the intake manifold.....

hypertec is right.one thing to add is after you jack up front of hte car remove bleeder screw(10mil) and start prouring coolant in to the radiator untill you see it run out of the bleeder screw.
then you're done

what i really recomend to everyone who does their own service is this

with this you can eliminate pretty much all the air out of your system. same procedure jack it up close open bleeder bolt then let car run for 20mins (or until thermostat opens once or twice)or so with heat ON .
