Anyone else having trouble with the tunnel coolers dripping water on top suspension wheels when stopped for a bit and then freezeing them up. It happens once machine gets warm and you stop for a while wheels freeze up and will not turn. How do I stop this from happening?:face-icon-small-dis

I haven't noticed a problem with mine. Are your wheels stock or aluminum?

Stock wheels in the top hole. It freezes up between the drop bracket and the wheel. Solid ice

Once i get mine back on the snow i will have a look. I carry a little plastic garden shovel and get all the snow and ice off before loading on trailer. Maybe give it a try.

Thanks, It don't freeze up unless I stop for a little break. If I clean it all out they will stay clean as long as I keep moving but freeze up as soon as stop again. Probably have to clean it out 3-4 times a day. Im really happy with how cool the sled runs with these coolers and the radiator deleted if I can just get this little issue resolved.

MPI cooling rails

I pulled the radiator and installed MPI cooling rails and love them. I haven't noticed the upper wheels freezing up though I am going to watch and see if mine is doing it also. I would call Mack at MPI if it happens I am sure they have heard about it and might have a solution.

Spray the wheels with 100% silicone spray before each ride... give'em a real good douschin'. works very well an ANY areas that seem to have ice buildup.

I am going to try some of this stuff on my sled next winter. I sprayed the underside of the metal skis on our snow scoot this spring and it seemed to cut down on the snow build up and made it go through the wet snow better. It says it works for ice build up too.

When I converted over to the Under Tunnel Exhaust and swapped out the plastic wheels for Aluminum I saw this BIG TIME.
