Hello, and thanks to all who read this and lend an opinion to me, I greatly appreciate it. To be upfront, I'm a very novice person when it comes to mechanical stuff, and I figured the best way to learn was to stop relying so much on paying local shops and start digging in on my own, cautiously of course. I do have a copy of the service manual, it's a 2006 Rhino 660.
I bought a 2006 Rhino 660 from my cousin who sold it to me for very cheap because of white smoke coming out of the exhaust. I took it to a local repair shop who had high reviews and a good rep among known people, he said I had to have the top end rebuilt. He rebuilt the top end and fitted it with a new Wiseco piston, and had it up and running for me when I took it back after 2600 USD, this also covered him cleaning the carb, cleaning the "CVT" as he put it, new battery, new tires (ITP Mudlite XL).
The second day of driving since the rebuild, I noticed that the electrical fuel pump my cousin had installed failed, I replaced the pump and all was working again. I used this pump:
I started driving it for a good couple days around the area and my throttle cable snapped at the end of the gas pedal, instead of re-soldering it, I just spent the 30 bucks and got a new one. I installed the new cable, and had to really mess with the throttle body a lot to get the cable in there. Apparently, functioning this throttle body a lot put a lot of fuel into the system and when I started it, the motor backfired and blew off my intake boot. I freaked out and thought I killed her, but a mechanic I know said it happens often and just reclamp it back onto the intake manifold. Did that, and started driving it around some local trails and having a blast. However, I still notice a gasoline smell whenever the machine is garaged at my house, and when I go back out to fire it up again there is still that smell. Mechanic suggested my float level could be off with the carb.
Then the next issue has reared it's ugly head, while driving I noticed my temp light came on, I drove it about another 1/4 mile and it was still on. I understand now that I broke a cardinal rule in the mechanical world, and yes....next time I see the light I will kill the motor right away and let it cool for a minimum 30 minutes, it's hot here in the Houston area. This was dumb of me, but not the dumbest thing I did...keep reading :(
Perhaps the biggest mistake of them all here, was the fact that after I had cut the motor off for about 10 minutes, we were burning up in the 95 degree weather and I was only a 1/2 mile from my home. I fired it back up and drove home, and had a noticeable loss of power on the way, I would gas the motor all the way and only got about 25% power the whole trip home, I drove it for about 5-10 minutes back to my house and it really started struggling at that point. I noticed that I couldn't even get it up the driveway, so my friend and I had to put it in neutral to push it up my driveway into my garage. I haven't touched it since.
After researching with Google, I'm terrified that perhaps I blew the head or cracked the block, but hopefully that isn't the case. My current plan is to bleed/burp the radiator and refill with coolant, then pressure test to look for leaks in the cooling system. I am also going to change the oil, I was told to check the dipstick to see if water had mixed with the oil. My fan is coming on also, but I was also told to clean the radiator itself as it may be blocked by gunk/mud/dirt/debris.
Anybody have any recommendations or things I should check? I also noticed that I am having the "R" light (reverse indicator light) blink on and off on me whenever this overheat issue happens. Think the "top end rebuild" shop is to blame here?
Thanks again for everybody's help and advice, it is greatly appreciated before I take on this project!
