: Can I Add A Radiator?

Hey All:

Sorry I've been MIA--been upstate, on an Island, and no internet at the cottage.

Last year, up on the St. Lawrence, due to thaws, etc..., the snow disappeared but the ice was good. Sleds without studs (mine, but hopefully not for long) especially, will overheat and become unrideable. I never noticed my sliders melting, but I definitely had to shut down a few times, and wait 15-20 min. before I could continue. This is even less fun at night, out on the River.

Someone told me for a few years the mfr.'s offered radiators you could add into the system, under the hood. My '95 Grand Touring 580 has heat exchangers only, of course. My questions:

1) Has anyone heard of this?
2) Is there a kit?
3) Is if from Ski-doo?
4) If it's non-Ski-ddo, does anyone have any ideas about where this should be cut into the cooling system, i.e., going to the heat exchangers, or on the way back? (IOW, if Ski-doo's not telling me how to do it, I'm nervous about whether an aftermarket vendor has thought it through sufficiently.
5) Will the added linear feet of cooling passages overwhelm the water pump, either resulting in too little coolant flow, or premature failure?
6) Related to this, what about the "dribblers" I've heard about, to keep the sliders lubed? Do they function with some type of bio-OK antifreeze, or are they just for summer fun?

I would just like a little extra insurance, or the ability to keep the temp needle from rising so fast in poor conditions, of which there are a lot of on an ice-covered River.

Thanks in advance,

Peter

blue,
i've seen radiators on older sleds and i am pretty sure it was the way they were made. i think it was a yamaha that had one on it.

Hi performance engineering sells radiators! Theyre custom fit to polaris but are very easily adapted to any sled.

as i think about it i remember seeing a sled at the fenwick grass drags with a radiator on it. the sled was one of those all out modified sleds.

when liquid first came out they had radiators. motors created a cold seize condition. this is where heat exchangers originated from.ice oval sleds had radiators. you could check with those guys.

In my 94 storm I had a buddy custom make a rad that I installed in the nose cone.I ran it in series with the heat exchangers and it works well other than the extra weight over the front end.

All:

Thanks for the input--sorry I didn't check back earlier.

TT670--Do you have an email for this vendor?

Tunedbear--My Ski-Doo shop man. states that the 582 mill has a thermostat that is "a double action type," which is "to give faster warm up of the engine.... This is done by bypassing the radiator circuit." It goes on to say that "these two functions have the advantage of preventing a massive engry of cold water into the engine."
Does anyone think this would protect against the possibility that an aftermarket radiator would cold seize the engine? From the diagrams, it looks like the thermostate dumps the coolant into the reservoir when warming up, and into the radiators when hot. However, the diagram is incomplete, IMHO, and hard (for me) to understand.

Again, I wonder where to cut it into the system, i.e., before the heat exchangers or after?

Oggy: Howd'ja do it, where'd ya cut it in and *gulp* what's a storm? (Showing my ignorance here, I know). Is your buddy a member of SW? I'd like to pick his brain directly....

Thanks again,

Peter
