car sat for 3 days and there was a puddle of coolant from under the oil pan, traced the leaking area to under the alternator, no coolant in oil and have done a hydrocarbon test and it came up negative (tested for cracked head gasket cause my car idle hunts on cold start)

drove the car to see if I could finda leak. ran fine, but later when I started it, it ran for like 30 sec than died

didn't see any more spray under the alternator

could it be my water pump? any ideas welcome

 

haven't had any problems with it before it sat, and had been daily driving it

 

I've had a hairline crack in a radiator before. Coolant would slowly leak out and evaporate. That's why I didn't notice it. I had to keep filling it with coolant. It ran fine. One day I finally blew a HG.

 

I'm going to look under my car tomorrow and check my o rings and tubes around the alternator

 

Water pump has a weep plug on it that occasionally fails. Start there.

Also, this question is not engine management related. Please move it to the model specific or general tech forum.

 

thanks

 

No problem
