My son changed the cracked manifold, thermostat, and fan about 3 months ago. Now it started to leak again. At first couldn’t see where but yesterday I saw under the reservoir tank, and it was green. What could this be? Also I have not had battery problems until yesterday I charged it and today it was dead again.
