Question about Chrysler LHS
Most water pumps have what is called a "weep hole" in them. It's there by design, and it's positioned so that as the water pump's bearing wears over time, it exposes the weep hole and allows coolant to leak out. This is so you know that the water pump is worn and you can change it before it fails and takes your motor to the great beyond. Most likely your car has one, so I'd lean away from it being the cause.
If your coolant is disappearing at a decent rate, chances are you have a head gasket leak into the cylinder, and the coolant is being burned away. Have you noticed any smoke from the tailpipes at all? If coolant is being burned off you should see smoke coming out and it should have a sweetish "coolant" smell if there is any significant volume of it. If you're not losing very much at all, it could be either a small tear in the head gasket, or possibly a coolant hose has cracked and is allowing some coolant to leak out.
If possible, I encourage you to park the car and put clean cardboard under the car. Let it run for 10-15 minutes with the cardboard underneath, revving the engine up occasionally (this will speed up the water pump, add cavitation to the system, and add pressure to the system as well). Then shut the car down. Check later on (at least a couple hours later) to see if anything has dripped on the cardboard. If it has, try to note as carefully as possible where on the engine it appears to have dripped from, and you can narrow down your leak spots from there. If the cardboard is still clean, then your engine must be consuming the coolant, and that would be a head gasket problem.

Just changed the timing belt, it started when it was in the air and the front of the engine was still off. put it all back together and it won't start. took the front off again and timing is spot on. getting fuel but no spark. any guesses?
