For what its worth i took a look at the 05 600 edge and it appears the cooling system is plumbed the same as the 04. Zero overheating issues over the years with my 05 that has over 8600 miles.

I don't doubt that for a second , like I say I think I have the wrong thermostat in there , if it is a bypass block off thermostat when the machine get's up to temp it is eliminating the rear coolers basically with the way it is plumbed now , which is the way it seemed to be when I had it out . I do have a thermostat out of the '04 head here , I am going to pull the one out of the machine and compare . I do still think the '03 is a better setup , it should warm up faster and then it is forced through the system in one flow , as opposed to the split flow setup on it now , again not that it won't work . One thing I just thought of , in the event of a thermostat failure and not opening , the '04 would provide more cooling as the bypass goes through the rear coolers rather than the closed loop on the '03 from the head to the bottle back to the pump . After considering that I may leave the plumbing as is , I am sure I have the wrong thermostat in it .

I had minor overheating issues with my 00 01-03 600 edges,,,nothing serious but they were apparent in very marginal snow conditions. Nothing of the sort with the 04-05 sleds. I do believe polaris made improvements within the cooling system/motor on these later models the older sleds didn't have.
I think your on the right track with the thermostat.

The '03 and newer had the larger front cooler, I'd want as much coolant going though that one as I could get.
Does anyone know if the '03 front cooler will fit in place of the '01 Edge front cooler?

are you sure its your temp light for temperature or det.you said you couldn't get on the throttle hard without the light coming on and cutting the timing the detonation system will do that and the temp light will flash.if the light just stays on and doesn't flash then its temp.04 and up has d.e.t.

No DET sensors in the 600 edges.

I believe DET was only on the 700 and 800's. The 500 and 600's did not have it.

No DET as stated . So I just checked and sure enough it had the bypass block off thermostat in it . I put the regular thermostat in it and am going to give it another go , I think it will be fine now . So when I ran it with the wrong thermostat the engine was basically only running off the front cooler , which by itself was almost enough for good cooling in mild weather , under heavy load and less than ideal snow for cooling . Adding the other three should give me everything I need , even with the 136" I think , if not I would be melting the sliders anyways .

A friend of mine did a 136'' edge conversion in his 04 800 prox using a polaris 136'' edge kit he found sitting in inventory at a local dealer here. I guess the kit had all the goodies making it simple... full 136'' edge rails, longer tunnel strip coolers, rear cooler,etc. He did a beautiful job on the sled looks all factory. No issues with cooling. That sled runs cooler than most 121'' sleds.
