My low coolant light came on like a week ago and my dad put more antifreeze in but it still stayed on for a day but has been off. I pop the hood and i am leaking antifreeze and the belts are slinging it on my engine. It took forever to get it cranked yesterday. I have never had a problem with my car its a 95 trans am with only 54000 miles on it. My grandpa said it might be the water pump but does any one have a clue what it mite be??

Sounds like you may have gotten the opticrap wet. Check the bottom of the waterpump and see if its wet. There is a weep hole on the bottom of the waterpump. GM screwed up by putting the waterpump right above the opti-spark without some kind of protection.

Check for leaks around the water pump. Check the heater hose for a leak and check around the bolts that hold it on. A bolt that has loosened will leak coolant and it will flow down to the optispark. Retorque the bolts of needed. If it's not leaking from these places, and you should see a stain around them caused by the coolant, then check the weep hole that is underneath the body of the water pump. You can see this clearly if you lay down underneath it. If it's leaking from the weep hole then there is a seal inside the water pump that is defective and is causing the leak. The water pump will need to be replaced if this is the case. If you were take your car to a shop, it would cost in the neighborhood of $700-$900 to replace the water pump and optispark. It's recommended that you replace the optispark (same as a distributor cap & rotor) when you replace the water pump since the only way to remove it is by taking out the water pump and this is a lot of labor. Cost is about half that if you do it yourself, but it's a fairly sizeable job.
