Hey I have a '94 hatchback civic that had a leaky radiator. i dropped a new one in today and drove it around the block and it seemed to be going well. I let it idle in my driveway for a bit and noticed a whistling which turned out to be the coolant literally boiling in the resevoir. The resevoir had a tiny pin size hole in it I noticed, but it was above the max fill line so I didn't know if that had anything to do with it. If anyone's got any suggestions I'm open to them. I don't know too much about cars, just that this shit ain't right. All help is appreciated.
