You probably have a water pump that is leaking. There is what they call a weep hole at the bottom of the pump housing and this is where the coolant would leak out on to the front of the crank pulley which would possibly get in the belt pulley grove of the crank pulley and spread it around when the engine is running. You could have a leaking thermostat gasket or upper radiator hose which connects to the motor that is leaking. There is no antifreeze which circulates in your pulleys nor are they filled with antifreeze.

SOURCE: leaking engine coolant from bottom of engine front passenger side

Probably a water pump seal unfortunately. Pressurize the system, with the engine off, use a mirror to look under the water pump pulley to see if any fluid is dripping from the water pump seal weep hole.
If it is, change the water pump.
Good luck, let me know.

SOURCE: leaking antifreeze from the fan

Hi,
The water pump will be directly behind the fan pulley. The fan pulley mounts onto the water pump shaft. So no the fan pulley is not the water pump.
Safe Journey's,

Antifreeze leak coming for around the oil filter and dampner pully. It doesn't seem to be coming for the water pump.

Make sure that you confirm this, as sometimes (not often) water/coolant can travel uphill....i would strongly suggest using a good torch and hand held mirror to trace the coolant's path, so as to avoid misdiagnosis.

Water leaking from behind a pully on the block. how or what can i do?

the pully that the coolant is leaking out from sounds like your water pump. with no coolant in the system the temperature gage wont read the correct temperature. replace the water pump and pray that the engine didn't overheat, as to do permanent damage.

Antifreeze drips from crank shaft pully area when running.

it's probably not dripping from the crankshaft... it would drip from the water pump just on top of it...

to check if it is done, take a flashlight and spot on top of the water pump. there should be a hole on top of it behind the pulley...

if it is damp, the pump is gone....

if not it might leak from the gasket...
