U sure do. not to hard to do be sure to replace gaskets and knowing if u have a dorman intake or stok helps gaskets are different most part stores will have to order the dorman gaskets. and DO NOT OVERTHIGHTEN !!!!!

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.
I would take a look at the water pump. There is a weep hole on the water pump to indicate if the seals are going bad inside the water pump. This hole is located on the top of the water pump where the pulley mounts to it. If this is not the problem, then it could be a number of other problems.
I would check the following items, which I have listed in sequence of cost to repair.
1. check hoses and clamps, if leaking you should see areas that have build up of dried antifreeze. 2. check thermostat housing on top of intake where upper radiator hose connects to engine. 3. verify radiator is not leaking 4. intake gasket leaking 5. head gasket leaking
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.
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.
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.
it could but- check passenger side front where heater core line go into manifold right behind alternator the hose line is connected by a press clip into an alloy fitting this fitting gets eaten away by anti freeze and hose angle pulls back on fitting the part is $18 at dealer and is screwed into manifold use caution if ur r going to replace at very edge of aluminum manifold---and check ur water pump bolts the 2 longer ones should have a lock sealant on them they bolt in thru a water jacket
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
