I have a 04 gtp 3800 supercharged and I'm losing coolant and running hot. I had the intake manifold gasket changed and it's still losing coolant. My question may be stupid but I'm gonna ask it anyway, the upper intake and lower intake manifold gaskets ,can you change one without changing the other??? Also any other probable causes and fixes will be greatly appreciated,. I am stumped on what it could be. Are there any sensors that could go bad to make it run hot? And now the idiot lights say that the abs and traction control need servicing ?? I hope somebody can steer me to the right direction or a good starting point.
Thanks
