What about the coolant reservoir in the back?

[@Chase.Mytrysak]

There is no reservoir in the back, it’s under the radiator on this quad

[@danielreynoso8981]

​@chasemytrysak5652 don't you need to also drained the reservoir and replace with new coolant?

[@Chase.Mytrysak]

@@danielreynoso8981 the reservoir is just for overflow. I didn’t have any coolant in mine so I didn’t have to drain it, if you have some it there should be a plug in the reservoir

[@jassemalzahrani4502]

I think it may be newer models maybe but yeah I have a overflow reservoir in the back as well

What type of coolant do they use

[@Chase.Mytrysak]

There is no specific kind. I used engine ice that I bought from the dealership. Just use an ATV oriented coolant

[@NathanXtoosheisty]

hey i drained my coolant but if i look in the radiator under the hose theres still coolant even after i flushed it with water what doni do

[@Chase.Mytrysak]

Sorry for the late response, did you use the bottle of water like I did? That totally flushed my coolant out and then I blew the access water out with my mouth
