Just had my water pump, radiator and timing belt replaced 5 months ago and now my coolant is leaking again from the front passenger side of the car need the front of the hood. What could this be?

look for a leak from the drain hole under the pump housing, if no leak not a water pump
take the car to a radiator specialist shop and have a coolant pressure test done to determine where the leak is
if it has plastic tanks for the radiator , they split with time and leak under pressure and a pressure test will reveal exactly where the leak is unlike a guess

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.

For a coolant leak you need to check all the hoses and fittings by radiator, heater core, expansion tank for leaks and/or integrity. Also make sure that your water pump is not leaking along with radiator cap and thermostat body. Overheat condition has no effect on battery - if it does not hld charge it is because it is chemically worn out and needs replacement. Until you correct water loss, have extra water in car at all times and run your heater full blast - windows open!!!!

May be the water pump,

CHECK FOR LEAKING WATER PUMP WEEP HOLE OR GASKET.ALSO CHECK WATER PUMP HOSE FOR LEAKS.IF ALL LOOKS GOOD.YOU COULD HAVE PINHOLE LEAKS IN RADIATOR CORE LEAKING ON FRONT OF ENGINE OR INTAKE MANIFOLD GASKET LEAKING COOLANT.

It sounds like you need a water pump. When the bushing in the water pump shaft wears out it makes a horrible grinding marbles together kind of sound and coolant leaks past the shaft seal.

there are many can cause the anti-freeze to leak.
you need to check to see if the leak come from the hose, water pump, gasket or radiator.
if it leak in the front then the radiator or hoses
if it leak on the passenger's side the it can be water pump or heater hose.
make sure you have coolant before you drive, because it can over heat and ruin the engine

Make sure it's cool, pop the radiator cap, Remove the shield on the passenger side between the tire and front of engine. Relieve the tension on the serp belt,draw yourself a diagram of the pulleys and belt routing in case the sticker is gone on the strut tower, remove the serp belt. Take the bolts out of the pulley on the front of the water pump (3). Remove the lower radiator hose at the front cover to drain the coolant. Remove the 6 mm bolts holding the water pump to the front cover housing. tap on the pump with a rubber hammer. Install a new gasket on the new pump, and a weap hole diverter in the pump (round black about hte size of a quarter), use old one if there's no new one. Install pupm and tighten bolts snug with a 1/4" ratchet. Install pulley and 3 bolts. Install belt, top off radiator with 50/50 mix green coolant. start engine and run to operating temperature,make sure the belt is seated in all of the pulleys and is running true, radiator fans should come on. Shut engine down and let cool overnight. Check level in radiator and overflow bottle, top off as necessary.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.
