I just bought a 1985 MKII yesterday, and it is overheating and losing all the coolant (comes out the vent on the fill neck) after a few miles on the road. I'm trying to figure out if there is supposed to be a hose attached to this nipple coming off the radiator fill neck, or if I just have a bad radiator cap. I looked around and can't see a coolant overflow tank anywhere, can someone help me out? I'm a complete noob to Supras. Thanks!
