Save Your Polaris Engine for $35 

I have the same silver Surefire, and I use it for mechanical adventures. Great light!Hope you feel better soon, Brian. Get lots of rest.

Thanks for the video, Brian! Very informative. Hope you're feeling better soon!

Whoa,I've never seen this kind of sensor failure before?Usually they just don't operate the fan,but this is something new to me!Thanks for your insight!

your awesome man i love all your videos wether they pertain to anything i'm doing or not wether your sick or not your awesome man

Man hope you get better, you always seam to be getting sick. Like your one shot videos too.

Love all your videos Bro

Get well. Get well soon. We hope you do get well.

Cool video. Hope you get better soon brother. :)

Well , nightmare valve sit explosion happen to me on my 77 Vw van 2000cc air cool , going the subaru way now. Thans for the fun video', Your brightened my day every time .

Hahahah "I survive the boiled of 2015" I laughed so hard with that haha you are the man! Cheers😃

That pump seal looks just like the seals used on swimming pool pumps. They use two spring loaded ceramic disks. They work great but you never want to run the pump dry. The friction of the two ceramic disks rubbing without coolant will cook the seals.

Annnnd now i know how to test a thermostat. thanks thats actually really helpful. i feel dum that i hadn't thought of that before.

Hope to see the video on the fork truck soon

that sucks. this sensor also failed on my 1993 legacy (which is my daily) but I saw the smoke coming out of the hot exhaust manifold soaked in oil and stopped the car before it could blow up. I not only replaced the sensor but also installed one of those old sensors (like in carburated cars) and plugged it to the other fan, so now I have two completely independent system that I hope will never fail. thanks and hope you'll get better soon

The engineer probably specified a good plastic for the impeller but purchasing substituted something cheaper. "just doing our job"

Hope you get to feeling better soon. Great video.

Hope you get to feeling better soon. Mullein leaf, elderberry concentrate, echinacea

What was the product that needed replaced and where did you purchase it from?

is there a chance that you could check the resistance and see where it falls on the resistance to temperature chart it should have shut down

Please tell me you own that Telehandler those things are awesome.

Where did you find a head for $500? I know this was years ago but I thought I'd ask.

Done the 1.9l Fords with the dropped valve before.

"the piston head got munchie munchie" hahaha

what size its the engine and how much it cost you to repair? means gaskets water pump belt and head at machine shop?

I have a honda rancher 350 with the exact same problem. What caused the seat to chip on your engine?

Brian what is the total cost of repairs? No warranty on a 2014 Polaris?

bmw often uses plastic water pump impeller and they go bad pretty frequently too which ends up causing all sorts of damage lol. Its a way they can make alot of money they recommend a complete cooling system overhaul after some time because alot of parts are plastic and basically deteriorate even with normal use

Great video even though your sick! This is yet another example of engineered failure I think. Maybe an aftermarket manual temp gauge is in order?

i have a 2015 rzr, do these have the same issue you are describing in this video?

The 4.7 Liter V8 from Chrysler/Jeep tend to do this also, and at very low level overheats also.

Hi, do you know if a 1999 Polaris Magnum 500 engine can replace a bad engine in a 1997 Polaris Sportsman 500? thanks man

Hey whats the name of the shop you work at? when i ever need a clutch replacing id like to come to you haha, i live in slc utah.

Nice vid, horrible cold you got there Brian , I didn't think Vikings could get a cold :)

Hahaha @ 2:25 .. that engine was tore up. Hope you feel better soon.

you the Man !

That is a brutal chain of effect! One small, cheap part fails, takes out other part, after part, after part! Sounds like it was designed to make Polaris some extra cash flow!

Does this apply to the sportsman 800 motor also?

Damn you pushed through that. I know this is an old video.

Not gonna read all the comments but did just watch the video and saw this is a six year old video So a couple things. First off I don’t believe that the engine overheated because of the sensor. 700 and 800 motors Are notorious for having the oil pressure regulator valve get stuck and create a low oil pressure condition which in turn overheats the motor and starts wiping components out. In terms of the cylinder you didn’t need to buy a brand new cylinder. Could’ve sent that cylinder out to 1 of 3 places to be repaired and replated and it would’ve actually been better than a brand new Polaris cylinder. And then in terms of the gaskets a complete engine gasket kit would have had about the items you spoke of for your valves, thin small metal inserts and the valve stem seals. I would’ve went with aftermarket valves as well. There’s definitely nothing special about Polaris OEM parts I am curious as to whether or not the machine got put back together and then the crank went out.

no temperature gauge on these ?

Have companies given up on plastic water pump impellers yet or is VW and others still uising the junk

2:55 You made a robot!;)

A couple years late, but both the head, and cylinder can be repaired for a tiny fraction of the price of new.

I feel ya man, I'm sick too.

Plastic water pump impeller. Genius!

Change the thermostat anyway, if it has been toasted it will fail sooner or later, and cook the rest again. Cheap to add to that big bill anyway.

Now way, a rzr 800 with engine problem. That's a very rare situation, kinda once in a million. Lol

I believe you could save a chunk by getting the cylinder welded and re-nickasiled. just my 02.

what will need fir rzr 1000 s

Good deal on that impeller.

Which motor is this?

Cheaper just to buy a new engine?

we had a temp sensor go bad on our arctic cat, caught it before it damaged motor, temp sensor $150.00... so we just wired the fan to the ignition, so if the motor is running, the fan is running. cost to repair about $0.50 for heat shrink, that was at least 3 years ago, never had any further trouble, also never replaced the temp sensor.

This is why I always have my speedo showing me my water temps... At least if the sensor failed I would see that I am not getting a reading anymore.

Those are some expensive parts. The Dodge 4.7l and 5.7l are great for dropping seats as well.

Brian great vid thanks for the info i have a question if you dont mind me asking i have 2012 rzr 800 and it started consuming oil real bad and after watching your vids i see theres no valve guide seals on the exhaust side it makes no sense as to why they didnt use one from the factory when you rebuilt yours did you use seals on the exhaust side as well ? . as far as the oil burning before i tear it down im going to see if it has some kind of crank case ventilation issue first then run a leak down check to try n pin point the problem but i have a feeling its more than likely oil rings . let me know if you have any other ideas thank you Bill

your water pump failed first. then it popped your temp sensor. I had the same thing happen to my scrambler 500 years ago. btw water pump seal is a glass seal and the oils from your skin touching it can make it fail so clean it before installing it.

The UHHHbama pic!! LMAO!! HAHAHA

Not surprised that the Polaris thermister failed, seen it many many times.

I think I would trash that thermistor and use an after market elec. fan controller, like what is used on after market elec. fan set ups. I would also have a switch to over ride it to turn the fan on manually. I think these polaris things are completely overated. Your vids are very interesting. Thanks

what confuses me here is how did the thermistor fail within an operating range it should have gone way outside of acceptable parameters for the ECU which Polaris has programmed to shut down the engine when it is outside of operating limits and also illuminate the mil light

Those seals are called "mechanical seals". Used a lot on marine salt water pumps.

I hope that by now you have recovered from the flu and have not exchanged it for Covid_19. Placing an Aluminium impeller into the coolant is a big mistake, the Fuji Motors work excellent with the original impeller, they also last forever!

Check the "SHOW MORE" above for links to the other videos on this Polaris RZR. I think you'll be surprised how much &%#@ came off the factory water pump impeller when it got hot. It's like one of those toys that grows in water!

Those heads are not the same. The new one has no combustion chamber dome. Whats up with dat?

Pretty sure that's a carbon seal. Not Good to touch with dirty hands. Will inbed material into it because how soft it is and will definitely cause early failure

Any theory on why the thermister failed like it did ?

Welcome to the world of Polaris price gouging on their parts. It's ridiculous

oh...thought you fixed that oil leaking into the exhaust...over heat from water pump failure

Furshitzled!!!

you shouldn't touch the face of a carbon seal.. the oils and such on your fingers will damage the sealing surface..

Now i'm worried my Polaris is going to eat itself alive.

Plastic water impeller! Polaris Engineering at its best!

Read Polaris and thought it is about Volvo tuned by Polaris that is going to be a crap.

so at a point the overheat light was on... then it went off due to a sensor failing... so your client kept on hill-topping.

I just dropped 10k on a Polaris lol, these vids freak me out! Lol

Take a hot shower and go to bed Brian, thanks for the effort. Get better!

dealer stealer,

Sudafed

Man flu is an awful thing. Get well soon dude.

Designed to fail... You're better off with a dune buggy. At least with a dune buggy, it's up to you what engine you put in it, tires, etc. (Good video...)

That's another reason why I would never buy a Poolaris

I own a Polaris,and as much as it kills me to say but they are not made well. Honda is the most bullet proof machine. My RZR 570 is great but has a lot of flaws. I see Polaris loosing the market with over pricing just Like Harley Davidson is slowly going out of business.

@briansmobile1 I know you know your shit but man you had me freaking out with that brand new head sitting on that skateboard with the sandpaper "grip tape".. easy way to ruin a precision Finnish.. anyways get better soon bud love the videos!

YOUR PERSONAL LIFE ? TALK ABOUT THE SUBJECT

Impellers aren't as common a failure as you'd think on these motors... usually the cranks and pistons. I'm happy Polaris did away with these 800 motors for the waaaaay better 900/1000 they use in the RZR, Ranger, and General now.

I liked the Obama thing. "Ahhhhhh"

i hate anything rotox can am ect junk buy japan stuff jujube cylinders prices to high bmw Mercedes dodge using aluminum engines now

A mental note to myself, AVOID Polaris!

Polaris are not engineered very well

The new "outro" music scares me :)

you just fucked up that mechanical seal at 2:07. those seals work by mating 2 highly machined ceramic surfaces together under spring pressure. the tolerances are so tight that fluid cannot pass between the 2 rings. even the grease from your clean hands or a human hair will cause them to leak out of the water pump housing weep hole.

you dont sound good brian

save your money and don't buy junk Polaris

just your average polaris... JUNK and a plastic impeller, REALLY!!!
