P1000 High speed and overheating

[duramaxman05]

I am working on a 2016 pioneer 1000-3. When running for long periods of time (about 10 miles) at 55mph, it will get up to 3 bars. Originally he brought it to me and it got hot and boiled over. I filled with coolant, bled it and did the burp method. Since I did that it will get up to 3 bars about 3/4 through the high speed trip. It's running around 6500rpm. Is that the nature of the beast or am I missing something? I figured honda developed their machine to run hard all the time.

Running 6500rpm's for mile after mile will make the temp climb on any sxs no matter what brand. If it's not puking or the temp light isn't coming on then it's fine, just running a little hotter than puttering around.

Nope. I run mine at WOT for 10 miles at a time in August, south Louisiana 118 degree heat index. Full windshield punching through the air. Never got up to 3 bars even after coming to a stop and idling for a couple mins. Look somewhere else like a partially clogged radiator or faulty radiator cap or more air still trapped in the system. What's the elevation where you ride? Less air density at high elevation could possibly lead to a lack of efficient cooling.

Does the owner ride mud a lot? Even if he doesn't might try cleaning the radiator fins, with HVAC cleaner coil cleaner , it's unbelievable what comes out of condenser coils using this stuff.

I did wash the radiator out. There wasn't much in it. I did pressure check the radiator cap and it held 15psi for 30 sec. The manual says if it holds pressure for longer than 6 sec, its good. He doesn't ride in mud. We are from southeast Missouri. Not sure our elevation is.

I would still try the HVAC coil cleaner, been wanting to do ours, just keep forgetting.

I will look into that. Thanks

I know there was a recall on the 2018's because the radiator fan wasn't coming on as often as it should.

The speed of the air coming through the radiator at 55 would surpas the stock cooling fan I would think.

could the timing be too far advanced?

It's a stock unmodified machine.

Is the fuel a high ethanol blend? I know small engines, like a lawnmower can burn up from high ethanol. No idea on a 1K, just a thought.

My son in law's 2018 was overheating and he thought the same thing about running it at speed to get some air moving thru it. Didn't work. He cleaned the radiator also. No help. That's how I knew about the recall. Before he brought it in his fan seldom ran. Now it kicks in fairly often. May not be your problem just my experience.

when i'm running around at high speed/rpm's with my tracks on in the snow and sub zero weather i'm almost always at 3 bars at least and even boiled over once,and there was no snow packed in the rad.

I'm pretty sure its regular 87

It seems like the 1000 has a marginal cooling system. The real fix may be this...

think that thing draws @12 amps

@joeymt33 can chime in he has one. It’s an impressive rad.

16’ didn’t have the issue

There have been a couple of machines that for whatever reason would overheat on long high speed runs. EVERYTIME. One member tried everything from new radiator, new fan, no thermostat, better fitting shroud, new cap, burped, the TCP radiator was the only thing that helped. It was weird.

I think we should start a over heat thread where everyone one that have a over heating issue post there last three digits of there PCM

When my family was in CO out of three Pioneer's my brothers was the only one to over heat and he had a fan override switch with the fan running all the time.

I've regularly do a 52 mile round trip to a local bar with mine and at times I'm 60 ish mph for 10ish miles of the trip and never have had this as an issue. I've boiled over before the ecm update but not since and when boiled over it was always slow technical trails never at speed. It sounds like an air flow issue. If moving forward at high speed I wouldn't think that we need the fan to generate air flow.
