Gravelguy413 Posted June 9, 2022 Author Share Posted June 9, 2022 What is the easiest way to drain the coolant level down before I crack things open? Quote Link to comment Share on other sites More sharing options...
fjh Posted June 9, 2022 Share Posted June 9, 2022 (edited) bottom rad should have a drain either on the bottom rad tube or the rad likley the tube! You only need to drain 5 or so gallons of coolant to do this! I f you haven't changed the coolant in a while wouldn't hurt to change it All ! install new 50 /50 coolant! Probably 14 gals or so!

Gravelguy413 Posted June 9, 2022 Author Share Posted June 9, 2022 Don’t see any drain on radiator. Could I just pull coolant hose off air compressor and drain down that way? Quote Link to comment Share on other sites More sharing options...
JoeH Posted June 9, 2022 Share Posted June 9, 2022 There's a fitting on the bottom radiator hose. Or it's on the bottom or left side of the radiator. If you don't care about making a mess, you can pull the compressor hose, but those tend to be very stiff. If you use the proper drain into a clean bucket, then you can re use the coolant. 1 Quote Link to comment Share on other sites More sharing options...
