Why does my 2003 intrepid dodge use a lot of antifreeze? It keeps going low and I put antifreeze. Can't find a leak. Could it be going to the motor? Please help. The car is still under warranty. We bought added warranty when bought.

pull the dipdtick and see if the oil is yellow or milky

You probably have a steam leak somewhere, that is, it isn't bad enough yet to leak when the engine is cool and not under pressure. That could be anywhere, but my first guess would be that the water pump is going. If the bearing is going in the water pump, it may only leak under pressure for a while. But as the bearing wears more, it is going to start leaking all the time. Other possibilities could be a pinhole leak in a hose or in the radiator that is only leaking under pressure. Or as the other poster alluded to, there could be an internal leak in the engine. Definitely check to see if there is milky brown streaks in the oil, which would indicate a blown head gasket. But also notice if the exhaust has a sweet smell to it, which would indicate a split in a cylinder wall or a head gasket leak that is actually leaking into the cylinder.

A friend had an intrepid which had a leak in the heater core. Had to be replaced twice while he owned it.

Put cardboard on the ground under the engine when you park it for the night. That is the best way to check for leaks. Or as a last resort take it to the dealer, you said you have an added warranty.
