Running Boards Heat Exchangers

[schroon]

We were out riding the other day with both sleds. They over heated once, so we stepped the speed up to sling the snow off the track on to the front heat exchanger. While I was waiting for the sled to cool I noticed the running board exchangers weren't getting any snow to cool. Is there something or someway to get snow on these? They seem kinda waste time if you can't get snow on them.

For the most part, the running board coolers are just air cooled. Snow rarely touches them unless your're in deep powder.

What conditions were you riding in? hard pack? ice? A set of ice scratchers can help in this situation.

Check your coolant strength, many have had issues with the stock coolant registering too strong. Cutting the coolant strength down and adding a product like "Water Wetter" can improve cooling as well.

I had the same problem even @ -10 F on hard pack.

I installed the rear heat exchanger from Pioneer (best price by far), diluted the coolant to 60/40 from the factory concentration that was off the scale (100%?), and added Water Wetter.

Haven't seen the temp light since!

Just pack snow on your running boards in those types of conditions and it will help with cooling. Once it all melts off put more on. That's how I got home in a freezing rain storm a few weeks ago.

I was in hard pack. I have a rear heat exchanger I have to pu on both of them, but with all the snow this year I thought I would be okay. Once I got the speed up past 20mph it started slinging the snow and it was okay. What are ice scratchers and what do they do? I have water wetter in and got the coolant down to 50/50. It only happened once when we were going 15-18mph. She likes to ride slow.

Ice Scratchers are spring loaded metal "rods" that scratch against the ground next to the fronts of your your slide rails.

They cause ice and snow to be thrown onto your slides / track and the underside of your running boards (heat exchangers).

Therefore they are good for preventing melted slides and engine overheating in hard pack conditions.

Someone had posted a picture of some home made ones that looked pretty good. Anybody care to elaborate?

Here you go..PIC of home made scratchers.

Ice scratchers

Check out the ski mounted ice scratchers from Hartman Yamaha. No risk of damaging the track, easy to "store" on the skis when you don't need them and work well.

Or, get some Simmons Flexi Skis, mount them in the aft hole, install the spray deflectors on them and solve many issues. No more darting, great in deep snow and a cool engine.
