    Water from under the vehicle? All A/C unit have a moisture drain hose under the vehicle, if this is what you mean. This is normal.

    No, the water is running down the bulkhead on the inside of the car and collecting on the drivers side floor. The drain tube is clear with no blockage. I believe its the evaporator coil.

My van started over heating so I changed the water pump and the lower radiator hose. The van is no longer over heating but I can still see coolant leaking on the drivers side in the front. HELP!!!!

The first thing to look at for overheating problems is the thermostat!

As regards your leak, the only way to find it is to look yourself whilst it is leaking using s good flashlight. It is going to be one of the joints that you broke and remade. I trust you put all the clamps back and tightened them? Did you put a new gasket and gasket sealant on the pump faces when you fitted the new pump.

Could also be a hole in the radiator.

A motor sound is coming from the rear passsenger side of 2007 Terazza van

What you are hearing is most likely the automatic leveling system air compressor. This is normal if you are hearing it occasionally. If you are hearing it frequently or constantly, this is not normal and usually indicates that there is an air leak in your air lines or air shocks.
