I have a 1998 MXZ 670 that came with a temp light and wondering if it is worth installing a gauge instead. A friend of mine put a gauge in his machine (not a Skidoo) and loves it. I was told that my light would come on before the engine overheats so l would have time to shut it off or run in more snow. I am not even sure what the spec is for snowmobiles and what temp they run at before they get too hot. I know they do not get as hot as a car, but seriously any one out there got any advise before l make my own decision. It doesn't matter to what kind of sled you have or at least l don't think it really matters. Appreciate any advise you have.
