Default 99 700 xc sp front hood grill

Im new to sleds and i just find it odd that the front grill on my 99 700 xc sp is open completely. Easily let in snow doesnt make sense. Nothing looks like its missing
Heres some pics. Its just below the grab bar. Is this normal? Would you not want to get snow out

There is a gap in the front, between the hood and the belly pan. Is that what you're referring to?

From the pictures, I can't tell where it's at, but don't see any sign that some backyard mechanic tried to solve a cooling issue with a hacksaw. Nothing looks damaged or dented, either.

The last time I had problems with snow getting under the hood was in the 70's. On anything as new as your sled, any gaps were there on purpose.

I had a couple gen2 sleds a 99 xcsp 600 and the 00 600 ves xcsp. Can't recall any strange air gaps in front nose of the sled...really never looked that close.
On another note i've noted poo left some air gaps between the belly pan and bulkhead on their edge chassis that we've filled in with a sealant.

Hmmmm yeah it really doesnt look like anyone messed with it. But figured atleast a mesh screen should be there or something since the top hood vents do. But snow will definitely get in there since you can easily see the engine through it. Like a 1 inch by 6 inch gap

And if it was designed that way, im confused as to why. Plow some fresh snow and its definitely getting under the hood... again this is my first sled so i may be a total idiot and just paranoid that if i dont fix every little thing, i think is wrong im gonna wreck something this winter

@p51mstg yes thats the spot right behind the front grab bar about 1in by 6 roughly. Is your sled open like this?

I don't have mine handy to look at, but have a picture that shows a gap like yours.

If I rode off trail much, I'd probably try to fashion a rubber flap or something to keep snow from getting in there, but it has never caused me any trouble and I never have snow or ice under the hood after a ride.

Under the circumstances, you're probably better off to leave it.
1 - Since this is at the hood hinge point, odds are good that any "solution" would bind
2 - With the exhaust behind this slot, it might be there to add a little bit of cooling air
3 - Unless you're in really deep snow, that spot is ahead of where most of the snow is going to get kicked up - very little will get in there
4 - Any snow that gets in there is going to hit the exhaust, vaporize and exit the rear vents

I really don't think you're going to have a problem.

One thing I would advise is a good cover if you plan to leave it outside or trailer it. I've had good luck with the Parts Unlimited custom covers sold by mail order places like DennisKirk. They fit better than I expected and seem durable.

The Polaris Gen II chassis was heavy, but good running and reliable machines. That snowmobile should serve you well. Your feet will stay nice and toasty with heat exchangers under the running boards, too.

that gap is factory. i do know we build water-x sleds. we have a 1999 gen 2 700 mod. water-x sled. we use a kids swim noodle cut to length and placed on the hood hinge bar right behind that vent. work's perfect for keeping water out.

you won't get snow or water in it from driving the sled in a lot of snow or on the water. you get it in there from the sled in front of you. if you think snow in your face is bad? try water-x oval racing. water fells like someone is repeatedly hitting you with a baseball bat.

IIRC, only GenII with running board exchangers was the 00-03 XCR800. My 99 xc700 got bulkhead + strip coolers

edit: Indy Triumph 600 had bulkhead + running board coolers
