A small pump circulates the coolant and fills the snowmobile via quick connect fittings installed in the snowmobiles cooling lines. This is done after every run down the track as Snowmobiles dont have radiators they have Heat exchangers that are usually sprayed with snow under the track of the machine. After a run my coolant can be near 190f . Most of the time when I change out the coolant it is near or lower than the air temp that its in.
