2001 Wrangler Coolant Drain?
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. Dennis B. |

4 liter block drain plug location:
http://i112.photobucket.com/albums/n...blockdrain.jpg You can also remove the lower radiator hose Use coolant CONCENTRATE and DISTILLED water to make your 50/50 The only coolant, that I am sure, meets the old DC 'Green" spec is Valvoline's Zerex Original Green or, if you prefer, DC recommends you upgrade to the new G-05 spec. The only supplier, that I am aware of, in the aftermarket is Valvoline's Zerex G-05 coolant. It is available at PepBoys and NAPA. FWIW: I find a flush-n-fill kit very useful and well worth the few dollars they cost. You cannot do a comparable job wit the old drain/refill procedure. http://i112.photobucket.com/albums/n...-N-FillKit.jpg "Dennis" <dennis@comcast.net> wrote in message news:B-adnQtlR5GBMLDYnZ2dnUVZ_vWdnZ2d@comcast.com... > 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. > > Dennis B. > > |

No, you can leave the t-stat in. Be aware that the heater core will still hold a fair amount of water so you should add half the system's volume of pure antifreeze and then top it up with distilled water.

Re: 2001 Wrangler Coolant Drain?
The flushing water that gets left in the heater core will be non-distilled
tap water, won't it? Some people like to blow this out with an air hose. Maybe not the commercial shops, but if it is your own car, then you want the coolant as clean as possible. Since the only potential source of contaminantin in the cooling system, other than breakdown of coolant, is tap water, you want to get it all out. That would be a good time to inspect the heater hoses for wear and hardening. Maybe this is an "optional" step, but think about the crap that can build up in a heater core and the difficulty of replacing one.

Since the only potential source of contaminantin in the cooling system, other than breakdown of coolant, is tap water, you want to get it all out. That would be a good time to inspect the heater hoses for wear and hardening. Maybe this is an "optional" step, but think about the crap that can build up in a heater core and the difficulty of replacing one.

Re: 2001 Wrangler Coolant Drain?
The flushing water that gets left in the heater core will be non-distilled
tap water, won't it? Some people like to blow this out with an air hose. Maybe not the commercial shops, but if it is your own car, then you want the coolant as clean as possible. Since the only potential source of contaminantin in the cooling system, other than breakdown of coolant, is tap water, you want to get it all out. That would be a good time to inspect the heater hoses for wear and hardening.
