| That looks like the overflow tube. It comes off right at the radiator cap. If the engine overheats or overpressurizes the antifreeze gets blown out towards the ground.It shouldn't come out of that normally, the radiator cap covers that but the spring on the cap can be forced up by pressure and let antifreeze out.
Several things can cause it. Worst would be blown head gasket, then bad thermostat, bad cap. |
