i drive a 89 astro van v6....here's the problom i'm having! when i start it up,and let it warm up. the temp. goes high and then goes back to normal temp. and then after driving it. it starts to go back up! but it never hits red only yellow,but then again it goes back down! i have no idea what it could be.....the oil is good,the tranny fluids are good,and the radator is good,and i just replaced the O2 senser....does anyone have any ideas? thanx.....
