Got the radiators swapped out. Super easy job on the OHV. Remove intake, drain coolant, unhook hoses, unbolt shroud, unbolt radiator, pull straight up and out. Reverse for reinstall... The 4.5 inch vertical crack in the front of the driver side tank along centerline half way down the tank explains the amount of coolant loss. Hopefully the current heads will be good to run on until the build. I kept a close eye on the temp running it home and it never exceeded the 200 deg mark since I blasted the heater the whole way. Ran it to work today with the heater off. It held 190 to 195 no problem we'll see how the trip home goes in the afternoon heat.
