You just have to find the other end of the hose and change it, or have a shop do it. It will not be very expensive, since it will be easy for them. You will have to remove a few things if they are in your way, but mostly can be changed with components still on motor. You should also check all hoses including vacuum hoses, your belts, etc., because if the car has not had regular maintenence, you will have more problems soon. Hope this helps, Rick

I will like to know if the antifreeze leak could be from the water pump if the leak comes from the bottom of the car and not from the radiator


ALL antifreeze leaks will be seen coming from the bottom of the car. Yes, it COULD becoming from the water pump. But then again, it could be coming from an intake manifold gasket, a heater hose, a throttle-body heater hose, a freeze plug, a timing cover, a heater control valve, etc..
To find out where it is leaking from, you must follow the antifreeze trail UP from where you see it leaking. Antifreeze leaks ALLWAYS travel downhill. Sometimes they can be deceiving also. I have seen intake manifold leaks at the front of the engine run all the way to the back of the engine and make it look like a rear freeze plug is leaking. Again, you must follow the trail to find the actual source.

Replaced water pump got new radiater top hose is good but i seen antifreez flowing on top of motor what could it be?


It could be residual that was already there, is your coolant level dropping? If it is, then check your heater hoses, thermostat housing and the rest of the cooling system that circulates coolant.
I hope this helps.

My 1999 blazer is leaking antifreeze. can't really tell from where but it does not always leak. most of the time it is over the weekend when I am not driving it.


You can buy or possibly rent a coolant system tester which pumps air into it to help locate leaks. Very simple to use. You just remove your radiator cap and replace it with the tester and pump it up to the PSI listed on your radiator cap and watch for leaks. I would pay close attention to the water pump and intake manifold gaskets. It could be something as simple as a loose radiator hose clamp. It is common for intake manifolds to leak and they expand when hot and contract when cool so the leak is more noticable after sitting. Look on top of the engine around your intake manifold and your heater hose for coolant or a chalky like residue which can form from coolant leaking. Your water pump has what is called a weep hole on it which will be located behind the pulley close to the shaft. You may need to use a mirror to see it. If coolant is leaking out of it the water pump will need replaced.

I am seeing water behind the pump on the top of the motor in the v under all the fuel injection / intake is that normal for water pump to leak there if its bad?


its not normal. the water pump will leak in front, not back. There is a pipe and hose down in the VEE that can leak. If the pipe is bad, you will need to remove the pump to replace it. The intake manifold will need to come off, to replace the pipe/ hose. the hose connects a pipe behind the water pump to a pipe at the rear of the block to a heater hose.

My truck just started blowing antifreeze from the right side of the motor under the alternator i pulled the brackets off the front and the water pump but i could not locate where it was coming from what...


If that is a 318 or 360 V8 check the small hose from water pump to the intake manifold they had a habit of developing a leak and it can spray over towards the alternator.
it is a short L shape hose from water pump to intake manifold.
Also check heater hose under the alternator for leaks or cracks.

My 2001 ford F150 is leaking water from above the trans


First off, is this water or antifreeze? If it's water it could be coming from the heat/air conditioning. If it's antifreeze, it's probably either a heater hose or the back of the intake manifold.
