Air trapped in the lines of your cooling system can make a perfectly healthy system run as though it's malfunctioning. These air pockets accumulate over time and can cause overheating by impeding the flow of coolant through the system. They also make the coolant level appear to be high when in fact it is just air pushing the coolant level up. Here is perhaps the best way to bleed air from your cooling system and make sure your radiator functions properly. Make a mixture of one part water and one part antifreeze. Pour it into the radiator, filing it up to the rim. Be sure to fill both the coolant or overflow reservoir with the same water and antifreeze mixture. Leave the radiator cap off, turn on your engine, and let it run until the radiator bleeds out air. It may take between 15 and 20 minutes for the engine to heat to the proper temperature and begin cycling coolant through. You'll observe the coolant level drop as the air is cycled out, and see air bubbles escaping from the radiator, and perhaps hear it gurgle.

Observe the temperature gauge as this is happening. The gauge should decrease to normal or close to normal. This process helps the radiator feed the coolant more evenly, helping the system cool the engine like it's supposed to. It's no longer circulating air in your radiator instead of coolant.Victorian Homes For Sale In Wheeling Wv Completely refill the radiator and the coolant reservoir again. Exotic Cat Breeders MnThey will be as much as half empty, since earlier it was simply air that made it seem full.Houses For Sale At Headland Hartlepool Seal the radiator with the cap. This will keep most of the air out of the system. Your car’s temperature gauge should be back to normal, and your engine should no longer have problems overheating unless there is a different issue causing it.

There are two other methods available for bleeding air from your cooling system. Some vehicles actually have bleeder valves specifically for this problem, located at the top or in front of the radiator. Open the valve and bleed the air trapped in the upper portion of the radiator. You can also jack your car to bleed the air from the cooling system. This puts your radiator higher than the rest of the cooling system and helps force the air pockets closed. Keep the radiator cap loose to help the air move out during this process.

Thought at first it had something to do with fan belt (tensioner?). Then I started it one morning with hood up, and watched for anything untoward. The inner mechanism of the air conditioner compressor (clutch I presume) was not all on, or all off, but intermittently spinning and stopping. Looking further, I noticed a little oil/dirt around the crimp fitting/hose interface. Sounds like I've got an expensive repair coming up... Living in Alaska, I could do without AC (guess I'd miss the drying function it provides the defroster) during the summer...can I take the AC out of the belt loop without impacting the other drive units? post #8 of 89 (permalink) post #9 of 89 (permalink) Yes .... the clutch is NOT a separate part for the Zexel compressor. Here's a reply I posted on a different board over a year ago: post #10 of 89 (permalink) post #11 of 89 (permalink) post #12 of 89 (permalink) post #13 of 89 (permalink) Find one that will remove a Zexel clutch.

Many of those kits do not include the plate and countersink bolt to remove it. Some are on Ebay for $55 or there abouts shipped. They will do more than a Zexel. Here's a link to a MAC tool instruction sheet that explains which of their adapters to use, and the adjustment gap on various compressors including the Zexel used in Subarus. post #14 of 89 (permalink) easy way to check... post #15 of 89 (permalink) Where is the AC low pressure side port on a 2000 Ford Focus located? The low pressure service port for the AC is located in front of the firewall on the passenger side just under and to the left of the passenger side windshield wiper motor. It has a green cap labeled "Evap Low Pressure Service Port. WRONG - don't do it i think it is under the plastic cover on the fenderThere must be significant differences on the 2000 Focus vehicles! On my daughter's car I finally tracked down the low side service port which is mounted on top of the receiver-dryer.

This device is well hidden, and I was only able to find it by tracing the plumbing -- no easy task in the engine compartment's crowded spaces.
The good news is you don't even have to open the hood. You cannot get at the low-side port from the engine compartment on this vehicle. The receiver-dryer is mounted beneath the fender directly below the right front headlight bulb and about 6-inches in front of the right front tire.
To get at it you have to remove the four fasteners holding the wheel splash guard -- the plastic shield that forms the "ceiling" for the wheel well. On this car there were three of those horrible plastic fasteners and a single steel screw holding the shield. The screw is located at the forward lower edge of the wheel opening on the fender. At the opposite lower edge (at the rear of the wheel opening) is a plastic fastener pointing upward. With the steering wheel cramped full to the left you can then see the other two plastic fasteners on the inside of the well and just to the rear of the center of the wheel.

IF YOU REMOVE WHEEL IT'S LOTS EASIER. The heads on the three fasteners are Phillips slotted, but I had no success whatever getting any of them to unscrew. I finally pried them out using a fine-bladed screw driver and a pliers -- damaging them somewhat in the process. If you pry out the plastic screw the rest of the fastener comes out easily using your fingers. It turned out I was able to reuse all three of these fasteners to reassemble the splash shield.
Once the shield is loose you can work it free (there is a slotted guide on the upper edge of the fender well) and the shield can then be lowered somewhat to the tire. With it in that position you can now move the forward section out of the way far enough to see the receiver-drier and the low-side service port. There is a protective plastic cap screwed onto the service port fitting.
When reassembling the splash guard be sure to align the upper slot before replacing any of the fasteners.  Another versionI think the ""Evap Low Pressure Service Port.

1 PSI MAX."" is not the port to re-charge the AC. It does not fit the recharger I bought at the mart store. The 3rd answer I think is right. I removed the splash guard and there was a port with a black cap near a "cylender" type thing. I recharged my AC a bit (it was just at the low mark on the recharger I bought) and it works better now. Thanks for all the help guys!
Ryan  Ha ha ha, I just charged my AC in my Ford Focus 2000 SE, 4 door sedan. It was located right in front of the front right wheel under the fender. Great now we can feel the breeze in the car. I didn't take off my tire. I jacked up little bit and squeezed my hand in between wheel splash guard and AC freezer bottle and took off the black cap. Rest was very simple.
