Got a 2001 Wrangler Sport with the 4.0 engine. I want to change the anti-freeze and wonder if someone could help me with a some questions. Does this engine have drain plugs in the block and if so where are they located? If no drain plugs then how does the old coolant get drained? Should the thermostat be removed before flushing? Better yet could someone please explain the proper procedure for flushing the coolant system on this vehicle? I want to do it right, that's why I came here. Thanks for any help.
