2011 Hisun 700 Coolant Leak

Hello All!  I heard a dripping noise after checking my drive belt for bearing noise (see other post).  I was able to determine that it was coming from a protrusion under the passenger side of the engine - see attached video.  Any idea what this is and what is likely required to repair it?  Thanks in advance!

Hi All.  I did a bit more research on this issue and the leak is coming from the 'weep hole' on the water pump.  Coolant will drip from weep hole when the coolant seal within the water pump begins to leak.  Oil will drip from the weep hole when the engine oil seal within the water pump begins to leak.  The purpose of the weep hole is to prevent coolant system pressure from forcing coolant past the oil seal and into the engine.  I have ordered a new water pump so suspect that will fix it.  Thanks!

      I posted this before , but I had the year wrong. The part I need is for a 2014, I don't know what all years will work, but I need the 2 bearing style with the spacer in the middle. It looks like this pic. If anyone has one I'll buy it rite away. my email is [email protected]. Thanks, RC

      After sitting this winter in a garage, I noticed coolant under the side by side when I went to get it out.  Does anyone know what would cause the coolant to leak out while in storage?  Any assistance would be greatly appreciated.
      Thanks,
      John

      So heard the grinding noise on the drive shaft a couple of times while going down a steep hill. Never heard this before going down the same hill. I already knew about the splines wearing out because of improper heat treating so I went through the process of removing the shaft to just replace it. A lot things need to be removed to get that thing out. Once I had it remove I didn't see any wear on the splines but what I did notice was the rear spline to rear differential had ZERO grease i.e. it was completely dry and I could see rust that had developed on the shaft splines and inside the differential mating surface. The front of the shaft where it connects to the transmission was well greased. Both ends of the shafts have springs in them with the rear spring being multiple times heavier which would force the shaft to mate securely into the transmission. Unless of course the rear is rusted and starts sticking which is what I think was happening. If the rear splines begin to rust and it starts sticking and the spring doesn't have the enough force to overcome the sticking because of the rust, the shaft will not get fully seated into the transmission. If this starts happening frequently it will eventually eat up the front splines on the transmission side shaft splines which is exactly what I see in the pictures of stripped splines. 
      I don't know why the rear spline shaft wasn't greased but this would cause it to eventually stick. I have been concerned about this ever since reading about it so as soon as I heard the grinding I stopped driving it. Thankfully there wasn't any wear. I'm wondering if this was deliberate or just laziness by the assemblers. It makes no sense not to grease it. The repair manual that I purchased from motorcycle doctor specifies to grease the splines. Both shaft ends have a rubber seal meaning there's is supposed to be grease in there. 
      I used to have a gold wing and there is a special grease required for the rear drive differential which happens to be a spline shaft setup. They use a lithium grease with moly. I had purchased a couple of tube of Magnalube-gx that I never used as I sold the bike. The Hisun manual recommends using a lithium grease which doesn't have the additives of a lithium moly grease that is specialized for spline shafts. Per magnalube website. "Magnalube-GX, however, uses a proprietary matrix of advanced polymers, molybdenum disulfide, and PTFE, so it stays where you put it without getting pressed out, while also maintaining a low frictional drag."
      Anyway, long story short everything is back together and no noise. I would recommend those that haven't checked the grease in the splines on both ends to do so before the shaft get destroyed. Especially If you have heard grinding. Those rubber boots can be pulled back without having to take to many parts off. If you've been hearing grinding then there is probably significant wear already and time to replace the shaft and grease it properly.

      Does anyone know of a bypass switch or controller. They make one for Polaris which installs into the harness that makes the ECU think it’s hooked up in normal position allowing vehicle to operate normally as if you are wearing seatbelt.

      I swapped out the Subaru motor for a Predator 670cc. If I remove the heat shield around the muffler, The stock muffler sits in there just fine with 1" to spare.
      Only problem is the exhaust exit is toward the back seat instead of out the back.
      Do you all think that the stock exhaust would be okay (just as effective) if cut a hole and welded a pipe on the reversed (opposite) end? Of course, plug the old exit end. Other option I thought of was to roll a tube 180° with a 7" center line radius and finish extention of 12" or so.
      Any thoughts?
