I changed the freeze plug in my 2001 Wrangler last weekend (in the rain of course) after one had corroded through and spewed coolant all over the place. I only changed the ones on the side. Only one had corroded through but I figured as long as I was there...
My question is I'm still leaking coolant and I'm afraid its the one at the back of the block. Anyone here changed one out? Do you need to pull the motor or can you just drop the tranny and work it from there? I have a pretty good collection of tools but anything special needed to make the job easier?
I did a search but didnt find any threads addressing this.
It's a bitch, but you can pull the driveshaft, drop the crossmember and let the tranny down as low as it will hang. Then you have to work up in there, but yes it can be gotten to without pulling the motor or head.
I really have nothing to add to this issue....But I do have a question. Growing up, my dad used to keep freeze plugs in the freezer for the old Dodge van. As a kid I started to understand the whole concept of the freeze thing. My question is how do you get the plugs out of the block. I can think of a couple things I would try (Liquid ref., or dry ice). But what is the norm for doing the job....?
thanks! can i just drop the tranny and leave the bell housing in place or do I need to drop everything to get to the freeze plug?
You can leave the tranny/t-case attached to the motor. Just remove the driveshaft, support the transfer case with a jack then remove the skid plate. let the jack lower the t/case and tranny down until it's low enough you can shimmy in there and do the work.
