Can this radiator shop build this if so 500 dollars is not much to spend to get the pioneer heating problems fixed the pioneer cost a lot of money

According to the guy at Davis Radiator Shop, 2500 E California Ave, Bakersfield, CA 93307, (661) 324-9886, the solution is not that simple. The underlying issue is heat transfer (engine block heat transfers to the coolant, the coolant transfers to the air). More radiator volume is not as important as more radiator surface area. In addition, the cooling system is limited by small radiator hoses and the small diameter of the thermostat. They recommend building a larger radiator (same depth, just more surface area), install custom-tight-fitting fan shroud, replacing the thermostat, and installing a larger more efficient fan. Translation: It will cost $500 to fix Honda's design issue.

Does yours overheat without the tracks and regular tires?

Does yours overheat without the tracks and regular tires?

Great question. I have only experienced overheating with the tracks. I am running MATTRACKS and the speedometer says we are going 15-17 MPH @ 4000 RPM, but the actual ground speed is 5-7 MPH. The tracks have a 3:1 gear reduction. I am also running in low range, 4 wheel AWD (everything locked). I have to run the transmission is manual (when I leave it in auto, it shifts at 6000 RPM and tends to be happy at 5000 RPM). The Dealer did let me I was "running the machine too hard", so I experimented with different RPM, driving habits and taking frequent breaks. Nothing helps, it still overheats. But when it runs...you cannot stop it. The Forest Service Gate was locked (they changed the combination) so we went around it in deep snow, at a 60-65% angle and it climbed like a Billy Goat.

Also, I did call MATTRACKS and they did some research. Most their Pioneer 1000-5 applications have been in the Midwest in basically flat conditions and they have no reported over heating issues.

The issue with the tracks is no air flow, high torque, high RPM. Bad combination for a Pioneer 1000-5 for an extended period of time.

I have ran the machine in Mojave when it was 110+ at 50 MPH with tires and it never overheated.

Yes, at this point that is the only option for a machine that cost 28K and you cannot use. My point is Honda knows there are overheating issues and it is not unreasonable for look into the issue. I have offered Honda to use my machine, send out a field engineer, collect data and experience the issues "first-hand".

If it was me, I would fab a shield on each side of the fan shroud to seal the shroud sides to the radiator. Pretty sure that will make a big difference. I know on cars it is huge having it sealed. With it open, the fan pulls air in from the sides of the shroud instead of through the radiator. Pretty sure they left it open to be able to clean mud out easier. These machines also run pretty lean. A Power Commander would allow you to richen the fuel mixture and run a little cooler also.

Missed the bit about the tracks, yeah thats a load on the machine.

When I was driving a Can Am Commander lots of people installed a Fan Override switch so you could manually turn the fan on and leave it on... Does Honda have anything like this?

YUP!

Cooling Fan Override for Honda Pioneer 1000 models.

 

[tate2326]

Does it seem to help?

 

[KERN]

Does it seem to help?

In my case no. After the ECM flash, the fan comes on at 3 bars (sometimes at 2 bars). With that said, I highly recommend installing the switch; my fan has turned off with 4 bars showing and coolant began puking.

Just came upon this thread from last year, and thought I would add to it. My 2016-5 also has overheating problems. But, it is mostly when in 9,000+ ft elevations in Colorado. I added a pusher fan to the front of the radiator that pretty much keeps the temperature to 2 bars, but occasionally gets to 3 bars. I also added an inline digital temperature indicator on my dash, showing the coolant temperature going into the radiator from the engine. I like seeing the real temperatures rather than the bar graph.
I am no longer worried about overheating on my Honda.
But, the comment was made above, and it makes a lot of sense, now that I think about it. With the engine compartment retaining heat, the cooling system would require more work to help cool the engine and get rid of that heat, so adding a vent fan to the engine compartment to cool down the front middle passenger’s seat area is making more sense. I think that will be my next project, as it does get rather warm for the riders.

Purchased new SXS1000M5D 2018 MANUFACTURED 11/17 and I am experiencing overheating issues (high coolant temperature, radiator fluid boiling "streaming" over, and fan turning off). Unit is driving from 4000' to 8700' in elevation, in snow, low gear range, 4AWD, typically in manual mode at between 5-6K RPM motor speed indicating 18-20 MPH. When in AUTO mode, transmission wants to shift up at 6.5 K. Gas pedal is depressed approximately 75% of range.

I have tried all posted remedies (burping the air out the system, making sure the radiator is clean, no debris or airflow obstructions, had dealer flash the ECM, etc.). Unit is current with all recalls and upgrades.

Honda is aware of the overheating problem and released suggestions in the The Wrench, August-October 2018 issue (see attached picture). scan Note: The reflash did not work and only lowered the point where the fan kicks on and the over temperature light comes on. The unit is still overheating,

Unfortunately, the local dealer has been unable to find anything wrong with the unit after three weeks of working with the Honda Honda's Dealer Representative.

I took the machine into Davis Radiator Shop 2500 E California Ave, Bakersfield, CA 93307, (661) 324-9886 for an evaluation and they suggested the following:
1. The radiator design is correct (super thin and high performance)
2. The cooling fan design is incorrect. At low speeds, the air flow is inadequate through the radiator, suggesting why the electric fan was installed behind the radiator to increase airflow, therefore improving the heat exchange characteristics. Under certain circumstances (idling or high speeds) the radiator will provide adequate cooling without the ECM controlled fan. However, under low speed, high torque, high horsepower demands, the radiator requires additional airflow for cooling. Unfortunately, Honda mounted the pull fan with a 3/4" to 1" gap with no air shroud to prevent recirculation or force the air to come through the radiator. Picture of gap IMG_2219

3. The hot engine compartment temperatures (known problem) contribute to the retaining/increasing the engine heat increasing the workload of the cooling system.

They recommended the following fixes:
1. Install an air shroud that will force the air intake for the fan to come directly through the radiator. This will provide maximum air flow and cooling. However, it could pose a problem during certain operations when the fan is not running. Perhaps, this is why Honda left the 3/4" to 1" gap, Need to conform with Honda's Engineers.
2. Figure out a way to vent out the high engine compartment temperatures. I seen several "Walmart Bilge Pumps" ideas that might work.

Any thoughts?

Did you ever fix this issue?

What a shame to spend such money on a machine and have to throw aftermarket parts at it to fix it.

 

[Youngone]

Thanks for the information. Just wondering if you tried running it with a new thermostat

 

[DenMachine]

Not suppose to be happening with Honda.....

This is a Polaris problem... My 2018 x5 has no problem here in Arizona. You may have a special issue.

My comment was in response to the op who’s Honda was overheating and it is a honda problem for some Pioneer 1000’s. And seems more of a problem in LE’s....
