Cooling Problem? (archive)

When I stop for a couple of minutes, my coolant sensor gauge starts rising. It will keep climbing unless I turn on the heater, which then it will not go any further. If I start driving, it will cool back down.

What could this be? I have a new radiator, I am thinking it is the water pump or the thermostat. I have a slightly loose expansion tank cap, but I don't think that it is the problem.

Also, I still haven't solved my dead oil temp gauge. I don't know where I should look for a grounding wire. Any help on this would also be appriciated.

Thanks for the help.
