Hello everyone,
been lurking for awhile, getting ready to pull the trigger on a xtz and I'm worried about these over heating issues.
I'll be running mine in glamis alot and run hard.
This seems to be the common link here, whats everyone thoughts?
I made the mistake of riding in one and I dont want to get back in my rhino.
Lets get this figured out soon so I dont have to buy a rex.

Thanks

I had 18 paddles so i am not as worried about this problem right now. I think it was just to much tire, I hope. I will post back up after i try some different paddles.

your's spit all over the place, BEFORE you put those paddles on.
PaPav, The paddles where givin to hapa to try out, he tried them and found out they were way to much. He will be trying different set-ups to find the right one.

Yes, i did over heat before the paddles and spit the fluid. i am wondering if my coolant wasn't low in the first place and that caused it to overheat even with the knobbies.

I did ask John at the Pro Shop if the pipe would cause a overheat issue. he told me it should actually run cooler once it was able to breathe better?

So i hit Ron Woods up and he told me about a coolant that has a higher boiling temp of like 375 degrees.

the coolant is XF Plus waterless Race coolant 760-244-7028

I haven't check it out yet, i may have to drain and flush the stock coolant. that is usually the case with race coolant.

next time out i will have less aggressive paddles and i will check the coolant level for sure before i ride. A work in progress just hope there is a solution.

It was cool out this weekend and i run in hot weather usually.

the first time i took it out over New years i rode in the dunes with the knobbies and no pipe I had no overheat issues at all. But I was still breaking it in and was not running it as hard for as long.

Hopefully it is a thermostat issue like the techs seem to think. If it is a head gasket issue, I would wait to buy one until they do an update. I ran Engine Ice in my 650XT and it ran about 15-20 degrees cooler with that in there. As long as we all tell AC about the problem, I think they will figure it out. papav, if you get a Teryx, you better get ready to put some serious money into that motor if you want it run...................

I think Ill go ahead and do it, I'm tired of working on this rhino. It would be so nice to have that kind of power stock. AC is offering a 2 year warr right now.
Thanks for all the input guys

OK got some info from Bi-polar Jim today. It is very important to burp and fill the water/coolant all the way. You jack up the front end of the Cat and get the radiator higher than the engine. He also told me to watch the fuse for the fan they pop real easy. There was more like taking off the water hose to make sure you fill the engine all the way up. and then lower the Prowler down and fill the radiator up if necessary.

There might of been more but he gives me so much info I cant keep up, sorry guys i am really just learning to work on these things.

You can get a replacement for the fuse, a 15 amp breaker at Napa auto parts that will reset itself if you pop a fuse for the fan.

But where did the air come from? Was it not bleed right from factory.Ive been through 4 head gasket in my rhino and always bleed it like Jim said but if it wasnt a factory thing then something else is causing them to overheat.
Hurry up and get it figured out so I wont have to deal with it.LOL

Hopefully its a bleeding issue

Thanks

I didnt think to ask "where or how the air got in there" lol

I didnt have my Prowler for a while so i figured they did it installing my pipe? Maybe it was when they put the thing to gether at the dealer ship?

I will keep asking around, i will call my dealer ship tomorrow and ask lol

Hey moderators, maybe we should sticky this thread so it stays available for other XTZ owners to find. If this is an issue that might occur more often for XTZ owners, it would be nice for them to have quick access to fix it.

"Arctic cat has a new model on there web site, its a green 1000xtz.

Did I miss this? Jim told me it was coming out but didn't realize it was out.. I can't find it on their web site either..

As far as overheating is concerned.
Cut out the winch plate! It is just a big wind block (if you dont need to use it)

Make sure if you run a front skid plate on your front bumper, that it is mesh.

Use engine ice or a similar like Ron Woods was suggesting..

When I was running the 650 motor I would have overheat issues all the time. I did have a big bore and high compression + nitrous. Doing these three things solved my overheat problems..

I was however paranoid when I did the 1000 engine swap, so I replaced the stock radiator with a aluminum aftermarket that mounts in the same location but is twice the width and relocated my oil cooler.

I made these mods PRIOR to ever running the 1000 motor so I can't say how much difference these two made.

But the 650 and the 1000 are basically the same vehicles with different power plants. Its easy to see why the winch plate mod works if you look at the front of your rig..

Engine Ice is proven as I am sure is the coolant RW is suggesting..

That's great info about the radiator filling process and the fuse. The problem is that both of our prowlers have run just fine on previous trips, so I think a factory air bubble is out. My fan was running fine, so the fuse is also not an issue for me. There is a deeper problem than air bubbles or fuses. I am taking mine to the dealer today. I have a feeling Engine Ice and Phat Cats other ideas are what is needed.............

I haven't had any issues with the ones we have up here, but we are only in the 40's and 50's temp-wise so far...
But from what I can see about the system, the issue of bleeding all the air out of the system would make sense. That doesn't help Dentless, he may have some other problem.

XTZ running hot
I also had a little fluid puke, just after we picked it up but never really thought about it much, just thought the cap was bad or the overflow was to full. Now that I’ve read this thread I’ve started to investigate a little.

I can’t run right now because it’s all in pieces all over the shop. We have it all torn down so we can build the suspension and other parts. Just about ready to start the cage and load up the safety gear.

Just wondering if anyone has checked the radiator cap or if there is bubbles in the radiator while running? If you got bubbles, it could be a head gasket issue.

I just talked to a mechanic friend who started off with coolant issues then went to a full blown problem. It started to steam out the exhaust, a classic head gasket problem. On the tear down he noticed two of the head stud nuts in the rear of the engine under the exhaust were loose.

Were thinking it lead to a head gasket failure, check for bubbles in the radiator and check the torque on the head stud nuts.
