What did you do to your jeep today?

[uss2defiant]

Flushed the coolant system and put the new thermostat in
Filled it up with only about 1 1/2 gallons and when the t-stat opens up it doesn't suck down into the rad
When it kicks on it'll drop the level down about 1/2" and then once it shuts off it goes right back up
Any ideas?
I loosed the aluminum bolt to allow the air bubbles to escape and everything
No leaks either
Temp gauge stays at half even when running for about 5 mins and AC turned on periodically

I take it the thermostat was installed in the correct orientation and also with the air bleeder in the 12 o'clock position?

working on the AC.
AC compressor is leaking.

fortunately, the store manager is giving me the warranty even though it was 6 days over but no warranty on the replacement part. better than nothing.

about a 1/3 of the way there......

stay away from omega compressors
x.x

hope this one holds up and actually pumps well.
that explains the poor cooling.
should have taken care if it like a year ago.
.......

got an in w/ the AC shop. the tech was happy to offer to buy me a better compressor at cost if this replacement is crap.
It's nice to find shop techs who are willing to let you in the shop and show you want they're doing.

wow.... 100 on the libby??

i couldn't go pass 95.
Also i think the cruise control maxes at 90 or 95.
don't remember from my winter trip to UT.

yea. I was passing some traffic and just left my foot in it to clear this big long line of left lane ********. I wasn't even floored either. looked down and saw 100 on the WAZE app, and about 105 indicated. it was still pulling too, and it was stable. I was surprised. Not something I'll intentionally do again mind you, but it's good to know all the work I did on it worked.

Also, not mine but...

I'm no expert, but that looks bad. 05 6spd 4x4 v6 158k for $2750. thinking way too much. Not the only spot on it either with cancer.

good techs are like gold. if you find one, treat them right. beer, pizza, learn when their birthday is, hookers, coke, whatever it takes. it ***** so hard when they retire.

Yep there's a little notch on the end of the hose for a small tab on the thermostat and that's how it was installed
Breather right on top
I let it run and the t-stat seems to be working correctly
It gets to the fill line and the t-stat kicks on until it gets below that and then shuts off
Also the temp gauge stays under half so it's not overheating and, correct me if I'm wrong, but if the t-stat was incorrectly installed wouldn't that throw the temp gauge off and it wouldn't even kick on
Still think I'm going to have a shop look at it to make sure everything is good to go although I think (knock on wood) it's ok

So does Pep Boys and, I'm pretty sure, Advance Auto.

O'Reilly's does too...

If the T-stat is installed backwards it will hold a decent temp at idle and short drives but the stat will begin to close as the engine gets hotter, thereby closing off coolant and making the engine even hotter. The temp gauge will peg on the wrong end of the gauge :emotions34:

So if it were to be backwards, then why would everything be working fine?
You can hear the thermostat kick on once the engine gets to operating temp, the gauge stays at half like it always does, and the coolant level is at the fill line
Wouldn't having it backwards, upside down, etc cause SOMETHING to be out of whack?
I haven't driven it yet but I let it run for about 10 mins and everything was working fine (I know you said at idle it'll display a good temp) but I feel like if it were to not be in there right, then the thermostat housing wouldn't have sat flush with the engine part it bolts down to since the stat has a tab to the right of the breather
Also I feel there would be some sign that it's not working right but it seems to be

 

[uss2defiant]

the thermostat is not the radiator fan. You can't hear it kick on.

The air bleeder should be at the 12 o'clock position and the pointy end facing towards the back of the jeep.

I'm not saying it isn't installed correctly - just some things to look out for to determine if the T-stat is installed backwards. It's unfortunately easy to do and I hate to see anyone have to remove that lower radiator hose and lose brand new coolant just to turn the thermostat around. :emotions34:

I still have my original one in at 155k. I'm not sure if I should change it and risk putting it in wrong or something or leave it the f*ck alone.

The one I had in there was the original I believe and I'm at about 174k
So it makes sense that it finally gave out I guess
11 years is a long time for it to have been working
I'm just glad I have it changed, because overheating is not a pretty sight :icon_eek:
I would change yours next time you do a flush just to be safe
I think you'd know if you put it in wrong because there's a tab on the stat that lines up with a notch on the lower rad hose end and if it wasn't lined up it more than likely wouldn't sit flush when you go to put the two bolts back in

You mean the thermostat housing and not the lower rad hose end.
And the notch you are referring too would be a key on the thermostat gasket.

My replacement mopar thermostat gasket did not have a key so just make sure the bleeder hole is in the 12 o'clock position if your gasket does not have a key.

Yes yes and yes
I have no clue on these terms for all of the stuff I just try and explain somewhat what I'm trying to say :happy175:
I'll just give up on this topic..

No worries.
I just wanted to clarify your post. that's all.
We're all learning.

 

[HoosierJeeper]

Especially me. I pasted some of this stuff into a word doc for when I do mine.

On my 04 by that mileage I had already done 3 complete flushes with new hoses and thermostats each time :Bye:

 

[tommudd]

By the way, left on Friday morning for Winston-Salem to move my wife down for a lectures position at WSSU. Fully loaded with clothes / some furniture etc got 18.9 mpg, thats through southern Ohio, West Virginia, Virginia and North Carolina, ALL HILLS ALL THE WAY. Not bad at all.
Total by the time I got back up here a little while ago was over 835-840 miles.
No issues what so ever with the 03
Coming back today lots of 80-85 MPH, she never slowed / hesitated one bit:gr_grin:
Thats what I like, check the oil and other fluids, tire pressure, load up and go, no worries

 

[jeeplib05]

Drove the KJ to make sure the thermostat was working fine and it was maintaining coolant level/no rise in temp gauge
All seems well
Also cleaned the cabin air filter out since it has never been cleaned

Not sure why my camera wouldn't adjust to the light this morning but I guess I have a pink Jeep :gr_grin:
Although it's probably in my head, it seems like the air coming in is MUCH cleaner than before
It smells fresh and felt great
If you haven't cleaned yours out I definitely would!
