Where is the low pressure port located on a 2008 Jeep Commander?


why ask this?
the kit has just one fitting and only fits 1 of the 2 test ports.
and the lines are all in clear view.
one big . one small.
http://www.wikihow.com/Recharge-the-Air-Conditioner-in-a-Car

The LOW pressure fitting is SMALLER than the HIGH pressure fitting

http://www.youtube.com/watch?v=7fUXowxiJSo

the lines can vary buy what engine option you have.
not STATED.
and is covered 100% in the FSM.
for all engines.
you can see the 2 A/C lines go through the fire wall to the evap.
you can see both lines. and both fittings if you just look for 1min.

the small one , is a bingo.

My 03 wrangler will not rev past 3,500 rpm


Do you have a trouble code for the throttle position sensor ?
If you have normal fuel pressure, the TPS would be the next thing to check. Problem could be in the harness between the sensor and the computer too.

Where is the low pressure a/c port on a 2002 jeep laredo for recharging a/c


This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY!

You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge.

You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage.

Take this job to a qualified shop.
Sorry

Where is the low pressure ac valave on my 99 Jeep Grand Cherokee?


Jeep Grand Cherokee SUVs manufactured in or before 1995 use R12 refrigerant. You mustretrofit these SUVs to accept R134 refrigerant using a retrofit kitavailable at your local auto parts store before you can recharge thesystem. In some areas, a license is required to retrofit an airconditioning system. If this is the case in your area, take your Jeepto a professional to retrofit the system.

Locate the Low Pressure Side connector port: You will find it on the driver's side of the engine.

Good luck!!! (rated this help)

Where do you recharge the airconditioning unit on a 98 jeep grand cherokee 4x4 loredo? Need the location of the fill valve. I already have the recharging kit.


Jeep GrandCherokee SUVs manufactured in or before 1995 use R12 refrigerant. You must retrofit these SUVs to accept R134 refrigerant using a retrofit kit available at your local auto parts store before you can recharge the system. In some areas, a license is required to retrofit an air conditioning system. If this is the case in your area, take your Jeep to a professional to retrofit the system.

Instructions:
  1. Step 1 Take your SUV to a mechanic to recover the R12 refrigerant out of the air conditioning system. A license and special equipment are needed to do this. Because R12 refrigerant is expensive, many mechanics will do the job for free.
  2. Step 2 Locate the Low Pressure Side connector port. You will find it on the driver's side of the engine. Remove the blue or yellow cap marked L. You only need to retrofit the system if you see a screw-type connector valve. If you see a quick connect valve, the system already is R134 compatible. Wipe the connector valve off with a clean towel. This ensures that the retrofit connector properly adheres to the valve.
  3. Step 3 Place the long retrofit connector from the automotive retrofit kit onto the Low Pressure Side valve. The retrofit connector has a special adhesive on the threads that will help it adhere to the valve. Screw the connector onto the valve. Tighten the retrofit connector using an adjustable wrench. Place the cap provided in the retrofit kit onto the retrofit connector. This keeps dust out of the system.
  4. Step 4 Follow the air conditioning lines away from the compressor until you see the High Pressure Side port valve. This is located near the Low Pressure Side service port. Remove the red cap and wipe the port off with a towel.
  5. Step 5 Put the shorter adapter onto the port. Twist it using an adjustable wrench until it is securely fastened to the port. Place the red cap from the retrofit kit onto the adaptor.
  6. Step 6 Fill out the Retrofit Identification sticker provided in the retrofit kit using a permanent marker. Remove the protective backing and place it on the interior side of the hood. This lets future owners and service professionals know that the system has been retrofitted.
  7. Step 7 Recharge the air conditioning system. See the related eHow titled "How to Recharge Air Conditioning with Freon in a Jeep Grand Cherokee."
WARINING:
Never try to evacuate the system yourself. A license and special equipment is needed to evacuate the system. Attempting to do this yourself will release refrigerant into the air, which is a federal crime.

Good luck (rated this help).

2002 jeep wrangler oil pressure gauge drops


When the gauge is at 0, is there any noise from the engine (tick, knock etc?) I would have someone put a mechanical gauge on there and read true pressure.Your driving pressure seems OK but if the low number is "real" something is wrong!
