Coolant leak
Hey,
Im new to the Firebird scene. I recently bought an 88 formula 350 TPI as a project car. It ran and drove well and planned on upgrading it slowly over time. I was driving it last week and it wasn't too far but at a stop light smoke was escaping my hood. I got it home no problem, (only about a mile from my house). when I opened it up I saw Coolant sprayed everywhere. It mostly was on the drivers side. I think its the water pump but there wasn't much, if any, coolant on it, but it was mostly on the underside of my power steering pulley. I got some insight on what else it could be ranging from water pump, radiator, to even freeze plugs. My plan was to add some coolant and start it up and see if i can find it leaking anywhere but its just been too cold for me right now. (Downriver Michigan) I was hoping to work on it this upcoming weekend, so i figured i would ask on here. Any advice would be greatly appreciated. Thanks
Additional Info: Not my daily driver so it doesn't have to be fixed asap, Starts right up without any noticeable problems
