Well today I found 3 wires caped together for the radiator sensor. I took the apart and found the one the runs the fan. Is here a way to know what ones go on that sensor? Its 2 red wires and 1 orange wire. I also found out that there is water in the pipe. I took the jug off and the piston is cracked and missing lots of metal. The dome has a few gouges in it. An I have a little water in the bottom of the crank. I cant seen to figured out were the water is coming from. The crank still spins free I don't know if i could get away with just a piston and getting the cylinder cleaned up.
