I have an 00 4.0L and i'm haveing trouble locateing the drain hole in the engine block for my anti freeze. From the dicription my manuel gives i think i found it but it is underneath the 2 header cats. Did i find it? Is there an easier way to do it?

Thanks yall, this is my first time trying to change the anti-freeze know where the bolt was.

 

just pull the bottom hose from the rad

 

Will that drain all the fluid from the rad. and engine block? BTW thanks for the quick response!

 

Bump
Anybody else have advice?

 

it will drain nearly all of it i would say 95 percent it is the lowest point on the system when i do mine it takes about 11.5litres to fill only hold 12

 

I'm not sure where it is man. I have the prestone flush T in mine so I just run the jeep for a minute with the hose hooked up to that and that flushes it all out. Leaves a little water in there but thats not bad.

 

Looking at the hose i can't tell how to go at it. I cant come from the top because i cant fit and if i go at it from the bottom it looks like im in the splash zone. any advice?

 

you will be getting damp

 

Remove the air filter box, this makes more room to remove the bottom hose from the water pump. Drained/flushed ours twice now (didn't drain the block either time). After flushing rad, block and heater core with a garden hose, I drained and refilled 3-4 times the rad and engine with distilled water. Doing that pretty much replaces the tap water remaining in the block with distilled water. The block holds about 1 gal. of water so I poor in the rad 1 gal of straight antifreeze, start motor (idle) and then add remaining 1 gal.+ of 50/50 antifreeze while the engine idles. Check rad (ENGINE COLD) for several days after and add 50/50 coolant to rad as needed. I always install a new rad cap after a coolant change/flush. Works for me.

 

I was hopeing to avoid that, but its life.

Good adivice. Thanks
