Good Evening, the first thing you need to do is park your car in a dry spot that way you can get a general area as far as reference where it could be leaking. Things it could be are a heatercore, a freeze plug or a headgasket or an intake depending on which motor you have. Seeing all you have replaced those are the few couple things that could be left. The 4cylinders usually leak at the corner of the head. The 6 cylinders would leak at the lower intakes. Let me know what you come up with. Hope this helps.

Car is lecking coolent and has a new water pump and not over heating and leacking but the tiers?

cars usually wont overheat as long as they have enough coolant to keep the engine cool. coolant leaks could unfortunately come from just about anywhere but if you didn't have a leak before your replaced the water pump I would start there. make sure all the bolts on the water pump are torqued right and it is not leaking and also check your hoses it could be as simple as a hose is not tight enough or there could be a crack in one of them. I would also check the radiator I have seen cars leak coolant where the fins connect to the plastic.

I have a 1999 land rover a4.0 i have a coolent leak in the water pump area it dosent look the water pump is leaking

Confirm that the leak is not from the pump.. With the engine cold and off, clean all surfaces which are wet. Make sure the top of the engine is not wet as well. Start engine and look for where the leak is using a flashlight. Be careful of moving parts.
Water pumps have weep holes that leak when the pump bearing is faulty, small holes on the top/bottom of the pump. Also look for leaks from the hose connected to the pump.

How can i tell if my waterpump is bad? shut the car off and came out later to anti freeze in the driveway

If it's leaking that bad, open the hood take off radiator cap and fill with water (without making a mess and spilling a bunch. Then simply watch for where the leak is at, if it's leaking from a hose, the radiator, or from around the area where the belt is located on the passenger side of the engine compartment. If it's leaking from the passenger side around the belt area your water pump is the most common cause. They are made so when the bearing wears out around the shaft the pulley bolts, it has what are called weep holes and the water just runs out to tell you to replace the water pump.

Coolent hoses leaks but cant really see all of the coolent hoses

U will have to find the one or ones that are leaking which is a time consuming job. Clean them then run the engine and see if possible to ape them or replace them.

Coolent is leaking from overflow and overheating

I will agree with your uncle and say that you should check the water pump. Start the vehicle and look at the water pump. Most water pumps have a "weep hole". If there is coolant coming out of this hole the water pump is not working properly. If not, and if the temperature has been running normally, you may have fixed the problem when you replaced the cap, if the water pump is good and the temp has been running high, then check the thermostat. Hope this helps and good luck.

Leaking alot of water /coolant

You have answered your own question almost. You will need to jack the car up and inspect everything being that its 91 camara, there is defintely enough room to inspect everything. You either have a hose leak, a radiator or water pump leak. Only inspection will find that out. Thank you,

Leaking anti freeze

If you are not seeing any coolent of the floor when parked, the chances are that you may have an internal engine leak, such as leaking thru headgasket and coming out as steam. Take your van to PepBoys for pressure testing for which they carge about $40.
