COOLANT LEAK PASSENGER SIDE - 2005 Chrysler Pacifica

Hi, maybe you have a faulty water pump or gasket, it's better that a mechanic check it as soon it's possible.

I'd have to see it in person to comment. The water pump is on the passenger side of the van.
A mechanic would fill the cooling system then pressure test it for leaks.

The water pump is on the passenger side of the engine.

Your heater core has developed a leak (of coolant). The smell is the "sweet" smell of ethylene glycol,
a component of engine coolant. The white smoke is steam coming from the heated coolant evaporating.
The coolant is dripping into your duct work under the dashboard, and apparently being evaporated
out of the ductwork and sent into the passenger compartment, meaning its a small leak.
When the leak gets worse, you may get wet carpet on the front passenger side.

You dont mention the year, make or model of your vehicle but generally a fluid leak on the passenger side interior is a coolant leak possibly from a defective heater core.Does it have a sort of sweet smell like antifreeze ? Also check under the hood to see if your engine coolant is low.

If the coolant leak is in side the car on passenger side then the heater core is bad. the only way to fix this is to replace it.

HI, The easiest way to find a cooling system leak to preform a pressure test. This test requires the use of some special equipment so I will just give you some common areas of these engines that leak. 1. check the upper radiator hose at the radiator. the plastic tank cracks sometimes. 2. check around the thermostat housing. 3. The worse for last there is a coolant passage tube that runs under the intake manifold almost impossible to see without taking things apart. but when it leaks the coolant seems to show up n the floor on the passenger side back by the firewall. I hope these help and you can locate the problem. Be careful when looking for these problems when the engine is hot you can get burnt. Good luck

That is the area the air conditioner vent drains. There aren't a lot of fluids possible - coolant, power steering fluid and transmission fluid are the only ones that would be in that position unless your windshield washer fluid leaks from the tubing. Brake fluid would be closer to the wheels. If the air conditioner runs at all it removes moisture from the passenger compartment and drains near the passenger side firewall. All the other fluids would hae a definite smell.

your heater core is going out on the car...its leaking water into the car
