daltonmcgill7 Posted July 31, 2012 Posted July 31, 2012 2.8l automatic leaks coolant from where the motor and transmission meet on the passenger side. :doh: :fs1:
jimoshel Posted July 31, 2012 Posted July 31, 2012 Freeze plug. Upper right rear in block. Might be head gasket. Is it leaking inside or outside the bell housing?
daltonmcgill7 Posted July 31, 2012 Author Posted July 31, 2012 how hard would it be to replace a freeze plug. Also what do you mean is it leaking from the inside or outside of the bellhousing
daltonmcgill7 Posted July 31, 2012 Author Posted July 31, 2012 its weird becaus eass soon as i put water in it it leaks right out it won't hold any water so i can't drive it
Eagle Posted July 31, 2012 Posted July 31, 2012 how hard would it be to replace a freeze plug. Also what do you mean is it leaking from the inside or outside of the bellhousing Do you know what freeze plugs are? The question was asked because there is a freeze plug at the back of the block, inside the bellhousing. To replace it, at the lest you have to remove the transmission and flexplate, and if that doesn't leave enough room to work you may have to pull the engine out of the vehicle to access the freze plug. If the leak is outside of the bellhousing, it may be a blown head gasket. From your description, though, it sounds more like a freeze plug.
daltonmcgill7 Posted July 31, 2012 Author Posted July 31, 2012 no sorry i don't really know much about the,m and it is leaking from inside the bell housing I'm pretty sure.amd ur saying I'm gonna have to drop the transmission to get to them?
sinkrun Posted July 31, 2012 Posted July 31, 2012 Yes only way sorry to say and make sure you replace all the freeze plugs good or bad on the motor while its out that is if you pull the motor.
daltonmcgill7 Posted August 1, 2012 Author Posted August 1, 2012 I'm probably just gonna pull the motor it has 274000 miles on it I'm sure i could get another at the junkyard for cheap or do yall thin i should replace the freeze plugs or swap to the 3.4l. also i have a 4.0 I'm not using will that fit?

Converting to a 4.0L in an '86 can be done, but it's a LOT of work. IMHO swapping in a 3.4L V6 is the best way to go. The basic block is the same, so it becomes essentially a bolt-in conversion and you get a much better engine with a bit more power than the 2.8L, and a lot more reliability.
daltonmcgill7 Posted August 1, 2012 Author Posted August 1, 2012 well its not my jeep and he just wants to replace the freze plugs can i pull the tranny to get to them? can someone explain to me how to do it?
Eagle Posted August 1, 2012 Posted August 1, 2012 This is not your Jeep? Don't even bother. Tell whoever owns it to either fix it himself or take it to a shop. If one freeze plug is bad, most likely the others are ready to fail. They ALL need to be replaced, and the best way to do that (as well as to access the one that's leaking) is to pull the engine. Candidly, that's more work than a high-mileage 2.8L is worth. By the way, you do realize that most people work on Wednesdays, don't you? IMHO it's kind of rude to post looking for help at 1:45 p.m. on a workday afternoon and bump your own post two hours later, when people are working and probably not just waiting at their computers to answer questions on the Comanche Club Forum.
daltonmcgill7 Posted August 2, 2012 Author Posted August 2, 2012 well INMHO i think your rude and no i don't work is there a problem with that maybe you need to check yourself on being rude before you go running your mouth
Pete M Posted August 3, 2012 Posted August 3, 2012 A Chiltons or Haynes manual should give you the step-by-step on yanking the trans. :thumbsup: I don't know of a writeup online for the 2.8/auto. I agree with Eagle that this is more or less a bandaid on an old engine. If one plug goes, the others are likely well on their way. if it was my rig, I'd yank the engine for a low mileage 3.1/3.4. Same level of work, but it should give many years of trouble-free service afterwords. :thumbsup:
Pete M Posted August 3, 2012 Posted August 3, 2012 and fyi it is generally considered poor taste in the internet world to bump your post so quickly. just so you know. :thumbsup:
