2018 T-Boss overheating, water pump question

[Joe Breaux]

I hope I was helpful to you guys.. I wish someone would have clued me in , in the beginning..   could have saved me a lot of cussing... Massimo Service Dept  was a complete joke, zero help from that useless bunch..   BUT, If these things run right , they are loads of fun once you get the factory flaws worked out!  ..

Would it need one if it's not supplying heat to the cab? I don't see the need for one unless it's used for heat.

maybe if you live in Alaska.....lol  otherwise no 

[Joe Breaux]

another weekend of no overheating..  I m telling you guys. BYPASS THAT FAN SWITCH!!!  Run the fan 100% ...IT WORKS 

[T-boss 410]

Does it cause any stress on the battery and/or the charging system? I know the automotive electric fans can draw a lot of juice. 

[Joe Breaux]

none that I can see.. charging normally ,no battery drain .Headlamps stil very bright.. but engine runs cooler by far 

[T-boss 410]

That's good to know.  What is used as an alternator on these vehicles?

[Travis]

if the alternator is not in plain view/belt driven, most likely there are copper windings behind the flywheel that produce current for charging.

[Joe Breaux]

theres definitely no belt so its probably like the old magneto systems.. someone said it puts out 20 amps ... hows yours coming 

[T-boss 410]

I meant to ask you folks, are your machines fuel injected or carbureted?

[Joe Breaux]

mine is fuel injected ..it starts easy, runs well.. 

[T-boss 410]

Mine is fuel injected, also. Has running without a thermostat and the fan on continuously, affected the fuel mixture or mileage? 

[Joe Breaux]

not at all.. it gets around 15 mpg on premium fuel ... Masimo manual recomends premium, not really sure it needs it. . same mpg as  before .. But at least now I can actually use it... 

[T-boss 410]

So, did you use it again this weekend?

[Joe Breaux]

Oh yeah.. I ran it all day today.. NEVER GOT HOT!  and temp was near 100* today..    I m telling you, run your fan 100%  , you will not regret it 

[T-boss 410]

Where are you that you get those kind of temps? I gotta say, I couldn't get used to that. 

[Joe Breaux]

Cajun Country.. Down in the swamp , south Louisiana.. our temps run high 94-99* ............but its so humid the heat index runs 108* to 112*  right now... I got up this morning at 5AM, it was already 88* !!!  And  the MSU  still does not run hot!!!!      FULL TIME FAN BABY!  I removed the winshield on mine.. much cooler for me 

[T-boss 410]

Weren't you fighting with Massimo about your windshield? Did you get hit with the last hurricane? I don't know how you can do it. The humidity sounds brutal. It gets hot and humid here in Ohio, but I doubt it compares to that in Louisiana. 

[Joe Breaux]

No, not me. No issues with windshield.. just too hot with it on... and yeah, Cat 5 Hurricane Laura devastated a lot of area in west LA with 150-180 mph winds and a 20foot storm surge ....but I am in central LA right on coast... we got 75mph winds and 6 feet of storm surge.. not too bad.... no damage to any of my three properties ... I am having a ball with this thing now that its working... I really enjoyed pulling my buddies Kawasaki Mule out of a big mud hole after he got stuck and I didnt on the Atchafalaya River 

[T-boss 410]

So you are happy with it now that you have the bugs worked out?

[Joe Breaux]

yeah, I liked it before. it performs well, it  just was SO FREAKIN UNRELIABLE . less than 5 miles and broken , 6 straight times in the shop and Masimo Service was so horribly bad .. They actually told me they stopped using HISUN engines because they were junk and would not warrantee them .. Mine had less than 300 miles.. His exact words were....." NEVER GONNA HAPPEN"     so Imagine my response . He hung up on me .. Now with some YAMAHA parts and full time fan, its working well .. I have put 200 miles on it since repairs ... NO ISSUES AT ALL 

[T-boss 410]

May I ask what Yamaha parts?

[Joe Breaux]

new Hisun Head,... Yamaha Head Gasket and Waterpump .. It ran perfectly yesterday again...    If you keep these engines cool, they run well... 

[T-boss 410]

That's interesting. Did Hisun supply engines for Yamaha, or did Yamaha supply parts to Hisun?

My engine is a Lanhai. Does the overheating happen only while being operated, or will it happen while idling? I let mine idle for a while a few days ago, it showed only 3 bars on the dash before the fan came on.

I purchased a colder thermostat and a lower fan switch to install. The thermostat is a 147 degree unit, and the switch is a 167 degree unit. I guess I'm just nervous about running without a thermostat. I've read articles on both sides of the topic. I just want to be as safe as possible. 

[Joe Breaux]

The Hisun engine in mine is an exact CHINESE clone of the original Yamaha Rhino ..The Yamaha parts are just more expensive and apparently well worth it!  I have no idea about the Linhai engines designs .. Massimo switched to them 2 yrs ago, because HISUN had so many problems ... In fact if I could not get this thing working, I had called a ATV/UTV engine supplier to see if a remanufactured YAMAHA engine would work.. He said yes 

[T-boss 410]

Gees, I wonder how they got away with that without a court battle of copyright infringement. 

[Joe Breaux]

You think China cares about that stuff?  They steal our military weapons and crafts secrets, build copies and sell them .. we do nothing.. Who knows if they paid Yamaha anything .. The Rhino UTV is exactly like my MSU .. I bet every part on it would fit ....thats a older version  rhino  below ... new MSU on right ... 

 

[T-boss 410]

Yeah, I guess so. But Yahama being the large corporation that it is, and the much smaller Massimo taking profits away from them, I just can't see Yahama looking the other way.  But it is what it is. 

[Joe Breaux]

a bit of news for you.. Linhai Motors  in china ... IS OWNED BY YAMAHA ... go figure 

[T-boss 410]

That actually makes me feel a bit better about mine. Thanks! Hopefully that means there's a level of reliability.

[Joe Breaux]

Well, dont count on it... look at it this way.. General Motors  owned the Airbag company in China that has killed 135 people with shrapnel from the charge going off  . And to date has had 30 million airbags recalled... Chinese built is still Chinese built .. those 10 yr old supervisors cant catch all the mistakes in the factory by the 9 year olds doing the assembly
