If you put that clamp on why can't you remove it and the muffler to turn the bolt around?

I thought about it but idk I guess I didn't want it to be a PITA to remove on the trail or something. Plus I went through all that effort to put that gasket material on it 🤣 maybe I was just being lazy at the end of the day.

I really don't get why it's touching, it wasn't before. Since there is that hanger on the trans mount I don't get how it ended up moving in that direction

Some times a small twist in the pipe is all it takes to shift some things over. Is it possible you didn't get the pipe lined back up exactly the way it was before you put the clamp on it.

True might be a real easy simple fix when I feel like tearing that gasket material
 
Since Mr @taylormade73 was (rightfully) mildly shaming me for all my ghetto air stuff, I decided to buy something halfway decent for once

I started working on installing my new compressor that I got from @Apparition, finally. I am putting it on the ABS tray, but it is a bit long so I am using some metal I had laying around to extend the tray to fit the compressor.

Marking where the compressor will go and where to cut the lip off the tray.

Here is the extendo-bracket. I was originally going to put it on top of the ABS tray, but I ended up putting it sandwiched between the ABS tray and it's support so that it would be more rigid.

Here it is installed:

Okay, so that’s a permanent mount and you have enough hose to reach any tire from there. Good job!

I’m on holiday det away with the whole fam damily. When I get home Saturday, I’ll make sure I have room there. Thanks.

Start with the easier, the thermostat. If it's sticking, it could cause the symptoms you described. To confirm my thought, I asked my AI mechanic about the symptoms. Here's what it said:

Yes—if the thermostat is sticking closed (or only cracking open a little), it can absolutely give you the one-two punch of:
  1. Overheating at idle or in stop-and-go traffic, and
  2. Little to no heat coming from the HVAC vents.

Why that happens​

Thermostat positionWhat the coolant doesResult at the gaugeResult at cabin heater
Normal (opens ~195 °F / 90 °C)Hot coolant leaves the engine, circulates through radiator and heater core, returns cooledTemperature stabilises in the 200–215 °F rangeHot coolant flows through heater core → warm air
Stuck closed or stickyCoolant can’t leave engine block easily; flow through radiator and heater core is restrictedHeat soaks in the block, especially while idling (water pump spins slow) → temp climbsLittle or no coolant gets to heater core → “cold” vents
Because the Jeep TJ’s heater core is plumbed in parallel with the radiator circuit (both branches sit behind the thermostat), any restriction at the thermostat reduces flow to both the radiator and the heater core. At road speed you sometimes get enough ram-air through the radiator to mask the problem, but at idle that extra airflow disappears—so the temp needle creeps up while the cabin stays cold.

Quick sanity checks​

  1. Watch the upper radiator hose:
    • Cold when you start → suddenly gets hot ≈ thermostat opened.
    • Stays cool even as the gauge climbs ≈ thermostat stuck closed
  2. Feel the heater hoses (carefully): both should get hot once the Jeep is at operating temp. One cold hose usually points to low/no flow.
  3. Burp the system: trapped air can mimic a stuck thermostat, so top up coolant and bleed air first.

Other culprits that can look similar​

Symptom overlapPossible causeHow to differentiate
Overheats at idle and no cabin heat• Low coolant level / air pocket • Weak water pump • Severely clogged heater coreCoolant level check; squeeze test on lower hose; infrared temp gun across radiator/heater hoses
Overheats at idle but cabin heat is OKfan clutch failure, clogged radiator finsHeater output proves coolant is flowing; look at fan operation and radiator surface temps
Normal temp gauge but no cabin heatBlend-door actuator or cable not moving, heater core cloggedBoth heater hoses hot → blend door; one hose hot, one cold → core restriction

Best fix path​

  1. Replace the thermostat (use an OE-spec 195 °F unit and a fresh gasket). They’re under $20 and take <1 hour.
  2. Flush/burp the system and refill with 50/50 HOAT-compatible coolant.
  3. Check water-pump impeller if problem persists—high-mileage 4.0 L pumps can erode or loosen.
  4. Inspect fan clutch (for ’97-’99 mechanical fan) or electric fan relay (’00-’06).
  5. Back-flush heater core if you still lack cabin heat.

My 04 TJ has a fan clutch, not an electrical fan relay. It's a 5spd but I don't think that matters. Think all the TJs had fan clutch.

I think the 4banger might have electric fans?

I forgot to update this thread but it did not start to overheat while idling on the trip to wheeler lake for whatever reason?
