I have a coolant leak in the back of the engine, today, I noticed a lot of water under the car, and I lose coolant level alot, I just added some water today to make it home. I will take a close look tommorow and ckeck if is the same problem.

So the level keeps dropping in the reservoir? If you have to keep adding coolant to the reservoir, the system is leaking or losing coolant somewhere. Have the system pressure tested to find the leak. Is the reservoir itself leaking? When the level gets low enough, first the reservoir will go dry, then the radiator level will start to drop.
Here's how the reservoir works: coolant is under pressure from the radiator cap seal. As coolant heats up from hot engine, it expands, and pressure forces the radiator cap seal up, coolant is forced into the reservoir-remember the hot mark on the reservoir? When car is shut off, coolant contracts, creating a vacuum in top of radiator. This vacuum works to suction coolant back from reservoir into the radiator, keeping the radiator topped up, and coolant should now be at the lower cold mark on the reservoir. It is a closed, sealed system. The only loss of coolant will be a very small amount of evaporation from the reservoir. If coolant level keeps dropping, there is a leak somewhere.
Look at the area where you park. Is there any fluid under the car that is not oily but rather is slick and has a sweet smell - yes, you wil have to stick your finger in it to see. If you find this type of fluid, you have a leak from somewhere in the engine compartment. Judge by the amount of fluid whether this is a major and potential calamity. (Lots of antifreeze could mean a bad hose or a bad water pump.)
Once you've checked for leaks, check the plastic reservoir that holds the radiator coolant overflow - is there anything in it? If you found alot of fluid on the ground, odds are that the reservoir will be low. If it is much below the fill line, add some water and coolant (50/50 mix) until it is back to the fill line.and check it for awhile to see if it needs more after you have driven for a bit (keep the coolant with you in the car just in case.) When the engine is cold, and as you are checking the reservoir, remove the radiator cap by pushing down on it a bit and turning it in the direction shown on the cap itself. Look into the radiator with a flashlight to see where the fluid level is. If it is more than 2 inches from the top, add a bit of coolant/water but not up to the top. Replace the cap firmly and add coolant/water to the reservoir cold level mark. If that all looks fine, you may have a bad water pump, a plugged radiator, a week cooling fan or a bad thermostat.
see this causes and fix it. God bless you Water pump -- A bad shaft seal will
allow coolant to dribble out of the vent hole just under the water pump
pulley shaft. If the water pump is a two-piece unit with a backing
plate, the gasket between the housing and back cover may be leaking.
The gasket or o-ring that seals the pump to the engine front cover on
cover-mounted water pumps can also leak coolant. Look for stains,
discoloration or liquid coolant on the outside of the water pump or
engine. Radiator -- Radiators can develop
leaks around upper or loser hose connections as a result of vibration.
The seams where the core is mated to the end tanks is another place
where leaks frequently develop, especially on aluminum radiators with
plastic end tanks. On copper/brass radiators, leaks typically occur
where the cooling tubes in the core are connected or soldered to the
core headers. The core itself is also vulnerable to stone damage.
Internal corrosion caused by old coolant that has never been changed can
also eat through the metal in the radiator, causing it to leak.
Most cooling systems today are designed to operate at 8 to 14 psi.
If the radiator can't hold pressure, your engine will overheat and lose
coolant. Hoses -- Cracks, pinholes or splits
in a radiator hose or heater hose will leak coolant. A hose leak will
usually send a stream of hot coolant spraying out of the hose. A
corroded hose connection or a loose or damaged hose clamp may also allow
coolant to leak from the end of a hose. Sometimes the leak may only
occur once the hose gets hot and the pinhole or crack opens up.
This may be the first sign that your water pump is failing. First sign is a leak. Crawl on your back under car if you can see if you can see it coming from front of engine near a pully that would turn your water pump. There is a "weep hole" it may be driping from.
If it's red, it's transmission fluid. Coolant would be green. Check the fluid level, don't let it get low, Chrysler minivans are prone to transmission troubles, and low fluid levels over time will ruin a a transmission. And be sure not to overfill, it's just as bad for the trans. Have the leak checked out and repaired, good luck
