Leaking anifreeze from the passenger side of the engine
The upper and lower hoses are not leaking and i cant see any leaking from the water pump which is in the front of the engine and my leak is coming more from the rear and side of the engine on the passenger, it started yesterday and it just keeps leaking is there anything on the passenger side of the engine towards the rear that would break to cause it to leak or do i have a cracked block or head gasket issue

check oil first. If it looks like a milk shake, its most likely head gaskets. (worst case besides a cracked head/block) could be many things. Check upper & lower radiator hose connections. (upper to water neck...lower to water pump) Check the heater hoses on the passenger side going from intake & water pump into the firewall. (should be a 3/8" size hose) Those are a more common leak on the GM vehicles)
if you hear a knocking or fast tapping noise, it could be the bearing in the water pump, and you could be leaking from the water pump flange at the front of your motor.
Hope this helps.
If you find the problem and need advice, let me know. eric
Tale the truck to a shop and have the cooling system pressurized to see where the coolant is coming from is my advice. They do leak at the heater hose above the passenger side rear most cylinder, remember water is clear and coolant is green or yellow or reddish colored and feels slimy to the touch, water is of course clear..
If you can narrow down where the leak is coming from, it will be easier for you to fix, but it is most likely either a minor radiator leak, or your water pump. You can put a can of radiator stop leak in your vehicle, such as bars leak. It wont hurt anything. If the leak continues, and appears to be coming from the engine area, the water pump is failing, but also check around the thermostat housing, near where the upper radiator hose connects to the engine
the water sound i believe is from being low in antifreeze..if you are adding water oncce a week then there is a leak.. try looking on the inside of the car on the passenger side carpet to see if its wet..if not, then check things under the hood such as, heater hoses for heater core, water pump, thermostat housing, radiator, core plugs, block heater..if the smell is coming from the inside and there is a film on the window, then chances are you need a heater core....try that.
The water pump bearing may be worn out and you have the antifreeze leak from the water pump or from one of the frost plugs on the engine block it self. Good luck and hope this helps, chances are it's going to be the water pump if it's the original pump.
really this could be one of several issues, does the vehicle run Hot, are you having to fill the reservoir with water or coolant, there is a hose that runs from the cap (overflow hose) to the reservoir, in addition to the upper and lower hoses, finally the water pump. the water pump is equipped with weep holes, which allow fluid to weep out when the pump is bad. finally the thermostat, hopefully one of these can solve your issue, good luck!
in the upper radiator hose to the engine side of an elbow with 2 screws in there is the thermostat and water pump need to remove the fan belt clucht with the fan off the bottom hose that goes from the radiator to the pump to remove the screws remove the pump the pump clean the surface and install the new pump
