My brother got his license and his first car. For some reason my mom didn't listen to what I had to say and got him a Saturn from a shady dealership. Well I told her something would happen, and now this car is leaking coolant hardcore. I drove it downtown and on the way back it started smoking so I pulled over and put some coolant in the reservoir. The temp gauge didn't register that it was overheating or anything. There is a hose that comes out from underneath the reservoir and it looks like the coolant shot out of it. My friend was thinking that the thermostat might be stuck and it builds up pressure and explodes out where the hose is clamped on. I'm still rebuilding my supra and now my mom and brother want me to fix his car now. Anyone have an idea how this could be dealt with? Thanks for reading.
