Getting Hot

[bensen]

Have 2012 Pro Rmk have trouble with it getting hot on trail going up even with scratchers down. Jump off into snow where possible. Any other tricks?

Fill track with snow if possible, helps a little for a short time.

Throw snow on the tunnel.

Check coolant level , might be low ?

Mine is really bad if I can't go very fast. Just one of these things. If you want a light weight sled you are going to have to make some sacrifices.

Have you done the $28 Mod with the doo thermostat and bypass??? If not, do that Mod and you'll drop the temps by atleast 30 F. Just go on Snowest and search $28 Fix; all the parts and instructions are right there...Did mine first when TRS put the thread on there a year ago... Went down an ice covered road yesterday for a few km, never went over 141 F.

I did the terra alps thermostat mod and also added the front tunnel coolant cooler , going to change the tunnel snow flap

thanks im getting tired of packing my tunnel with snow on the way up the hills.

Thanks for all the info. So the $28 dollar fix sounds like it helps. mine was hitting
165 yesterday. Will defiantly try this.

I did the doo stat and noticed a huge difference. Used to be around 130 on the trails. Now the temps are around 116 on thin snow. Only works when you have some speed kicking up snow on the coolers.

On the 14 pro makes a big difference switch to ethonal mode. My understanding it retards timing a few degrees and dumps more fuel cuz ethonal needs more for btus

Ive never had a problem with mine. Sometimes the snowflap folds under, but i notice that when it jumps up a few degrees. Mayb check the tension springs on the scratchers, they do get tired eventually and the scratcher just floats there rather than being forced down.

We use our doo billet thermostats on the pro's as well. Not sure what the $28 fix is. Our kit requires removing the stock stat from the head, then plumbing in our housing a bypass hose and an aluminum t for down in the front of the engine just before the water pump.

Thank you

Its the same thing your doing but with the stock doo thermo that costs $28.

If your not getting any snow on the coolers it doesn't matter what you have for a thermostat its gonna run hot.

 

[Deano670]

I wouldnt give doo 10 cents for their stock stat, thats why we change to the billet housing with a cat stat. Drops 28 deg f, flows twice the volume of the stock stat. No sense in having all that cooler of flow is restricted either.

Whats your aluminum t-stat worth? What temp does the stat open/full bypass at? Terra alps offers one aswell.

 

[rmscustom]

What does your kit run for temp in good snow.

 

[BILTIT]

For comparisons sake, my terra alps kit runs 98-105 in snow. I also have an aftermarket head and a lot of venting.
