Upper Engine Temp Range - 900 Fusion
- Thread starter Kariblay
- Start date
If you are referring to water temp as displayed on the factory display -
A decent warm up and heat cycle to let the crankshaft come up to temp is very important on the 900s... Let it come up to 126*F and then shut it off for about 10 minutes to let the motor heat soak, then restart and let it get back up to 126* again before starting your days' ride (going easy for the first 5 miles before laying the coal to it).
After that,
126 is Optimal
126-150 is ideal
150-175 is getting hot, be sure to put scratchers down if you haven't already. (I like to run them when in less than 4" of new soft snow or if temps hit 140)
175-190 is REALLY hot, stop and pile snow on the running board coolers to prevent premature engine wear.
200-215 is DANGEROUS, The sled will go into limp mode and reduce power at approximately 215*F
215+ If you continue, Engine Damage WILL occur if you get it any hotter than that without IMMEDIATELY stopping and shuting off the sled, packing snow, etc.
Remember that any time you stop for a lunch break or for more than about 10 minutes or so, you should be sure to let the engine come back up to 126 before proceeding as the motor will cool rapidly and gets a 'cold shot' from the coolant that has been sitting in the tunnel coolers.
Sorry for the long answer to a short question, but I like to be thorough on this topic
