Re: clanking sound that driving me nuts.
1. How hot should the engine be on a normal driving? looking for a
temperature here.
2. Where is the ac evaporator on a 1995 jeep grand cherokee, my ac has
that
dead mouse smell. gonna do the lysol thing and that.
3. Should i do a cooling system flush, maybe the engine is not properly
cool thereby
causing it to over heat and clank.
thanks

Re: clanking sound that driving me nuts.
I had EXACT same noise during hot conditions/intermittent etc. on my old
'95 Grand Cherokee. There should be an inspection plate/cover where your
trans. and torque convertor meet the engine. Pull cover and eyeball the
bolt-heads, they are "ticking" against the flat plate cover after enough
heat expansion takes up the minimal clearance. As far as othe noise...l
found a heat shield above the Cat conv. falling off.

Re: clanking sound that driving me nuts.
Really, interesting. I took it to the people that rebuilt my
transmission and they were like, it's fine. "we took it for a drive and
heard nothing"
was it when you put it in park the sound goes away? what did you do? i
plan to drive it off a cliff or a river, whichever comes first!

Re: clanking sound that driving me nuts.
Dude, my 97 ZJ does the exact same thing after having my trans rebuilt. Only
does it when it is hot out, long slow moving traffic or slow moving on the
trails. It got so bad once it sounded like a bolt wizzing and gringing
around the scatter shield between the trans and engine block so I shut her
down, removed the access panel to see if the guy forgot to tighten up a torq
converter bolt, but nothing was lose or missing..?? I let it cool for about
an hour, started her up and all was fine..?? Over the months I noticed the
clanking will go away once the torq converter locks up, I even have the
sound on video as I record allot of our trail rides with a bumper cam,
showed it to the dude that rebuilt my trans (from Mr Transmission) and he
swears that sound could not be comming from the transmission... But it IS
comming from the transmission, so I will prolly have to eat another rebuild
sooner or later cuz of that noise..
Now, I do have close to 100K miles on that rebuild though, I change my fluid
and filter every 30K - 40K miles as I am terrably rough on her, and can
drive 400 miles in a bad week for my job while rolling 32" mud tires,
factory gearing and a 4" lift. Very embarrassing to pass other trail riders
as I am sure they think it is a rod knocking, my clanking will get so bad it
WILL make the noise in N or park, the olny cure I have found is to either
stop and let her cool down or drive maybe 30 miles on the highway so the
torq converter will lock then it will cool down on it's own and stop the
noise. I had the trans guy put an external trans cooler with a rather large
fan on it right after I 1st noticed the clanking sound, did not help but I
am sure it did not hurt either..
