Warrior Heat Exchanger Question

[rx1mtn]

I have installed 2 of these coolers on RX1 Mountains, no problems, both coolers had very good instructions with them. These coolers ARE made for the Mountain sled only but will work on the Warrior. Look at what Lazy Bastard has wrote and follow his directions, I'm sure he knows what he is talking about.

more work

More work than I thought

The cooler will fit great if I cut my tunnel protectors or take them out. It looks like they are riveted from the top. Real PITA to take the exhaust out just to remove the protectors. Even then the first big bump and my studs will take the cooler out.

geeeees If I have to do all this to make my Yamaha dependable .... maybe I should have looked more at others.

You didn't need to do that to make it dependable. 99.99% of the Warriors didn't have that rear cooler and didn't have any problems. Sure, you would get the occaisional temp light, big deal.

Are you overheating the sled that you need that exchanger?

Come on Mighty, you are usually pretty level headed and look fairly at all the issues raised here. I don't think the Posts here support that 99.9% of the Warriors are having NO overheating without the cooler!

There have been reports of Warriors side-by-side where one overheats and one doesn't. Several of us have melted the bottoms of our boots. We've reviewed air in the system, coolant/water ratios, etc. ad nauseum

I'm still wrestling with what the answer might be but I have a hard time understanding the [lack of] engineering at Yamaha that designs sleds like the SX-R triples with smaller motors (but much more heat exchanger area) and then can't assess overheating problems when the motor is 50% bigger with less cooling.

I think some of the after market skis some are using may be part of the equation since they "spray" more snow which bathes the running board exchangers with additional cooling. There can't be so much difference sled-to-sled - unless some of the exchangers are restricted or the cooling system is otherwise restricted.

Just MHO.[/b]

I don't consider the light coming on occaisionally to be a over heating issue. Yamaha is super safe and programed the sled to shut down before it gets too hot. I have yet to read about anybody having issues with their sled always shutting down. Mine did once while it was idling while my buddy used my headklights to repair his sled

I remember the '92 V-Max 4 had a heat exchanger in the front of the tunnel, the two that ran the full length of the tunnel, the one in back, and of course the radiator. I don't think there was any chance of overheating that sled.

The more heat exchangers the more coolant the more weight that is published in the mags............................Politics

done

Its in ... easy job if your comfortable cutting away your tunnel protectors and opening for the hose fitting.

now if it just stays clear of my track I'm in good shape

 

[sledheadgeorge]

It will not stay clear. Trust me I know. You have to extend the tunnel protectors. Its cheap insurance.

clearance

Had to test ...

Compressed shocks through full travel. Test is static with no track bounce or wipping around.

Leaves about 2.5 inches of clearance

 

[impalapower]

Just to be safe, I'd get some exchanger protectors. At least then the track will slide easier and not grab at it. You don't need to be at the side of the trail when you are out for a weekend.

I'm with you on this one. Cat had problems on their 03 Mountain machines with the track yanking the hoses off their rear exchangers (the 04's now have protectors over these hoses). If you were to look at or even measure the distance between the lugs and the exchanger with the suspension collapsed, you'd think it was impossible for there to be interference.......... but trust me..... I've seen a 1M pump out ALL of it's coolant.

One ride with me this winter and you will see that the laws of physics do change once you ride a snowmobile on the snow. Extend your tunnel rotectors. Been there and done it
