Exclamation HELP - Over Heating!!!

I've drained & flushed my radiator, & replaced upper & lower hoses. Flilled with new coolent & water wetter. Dag nab thing is still over heating!

I have an aftermarket temp gauge...(FYI).

What the hech is wrong? I've jack the car up when filling it with new fluids ect...ahhhhhhh. The temp also seems to go up, and then (after a while, go down). Do I have a plug (mineral deposit posit build up) in my raditior?

HELP!!!! PLEASE.......mad THANX!

Did you bleed it after you filled it up?
[bleeder screw is located right after the upper radiator hose is connected to, on the engine side]
after u bleed the coolant for air bubbles, turn ur heater on (don't turn the car on yet) and switch the climate control so ur using the heater core instead of having the heat come from the engine bay. (hard to explain that part, but there's a button on ur climate control that has a pix of car and arrows representing circulation inside the car). then keep the radiator cap off and turn on ur car, have it cycle through, at the same time ur able to check if the coolant begins to make a "swirling effect" meaning ur waterpump is fine. then put the cap back on before the engine gets warm enough to start spitting out hot coolant. finally keep the car on to have it cycle through some more, and keep an eye out on the temp gauge. this should fix that problem, assuming that ur water pump in good shape. hope this helps.

I'll give it a try. I was think'n that the dude that had the car before me used tape water instead of distilled water, causing a mineral build up so where in the radiator. I know the themostate is working cause it's blowing hot air...

Thanx for the advice...much appericated!

I agree, If he did not remove the bleeder screw to get rid of the air bubbles the motor will overheat. bleeding the system will help the overheating problem.
