Coolant leak!!

[coloradowill]

I have a coolant leak on my 04 rev 800 and i can not find it.The coolant seem to be coming from the back of the motor .It is srarting to make me mad. It does not leak when it is not running but when I start it it starts to leak.Is there anyway to find it without taking the motor out.

Front cooler possibe, maybe off the hose under the motor to front cooler, or cooler has a crack, has happend to a lot of a sleds front cooler crack, probably some how
have to get the sled jacked up in the back good enough to see under when running, good luck

Make sure it is not a head gasket. That can get spendy in a hurry if coolant gets in the cylinder.
