What eats slugs

Hedgehogs, newts, toads and some birds, such as song thrushes, love to eat slugs and snails, so it is a great idea to attract these beneficial creatures into your garden. Probably the best way to attract them into the garden is to make a pond or boggy area, which they will use for drinking or as a place of refuge.

The slug fell out out the coil in the TX RF amp chain. how do I adjust it/

The slugs don't normally just fall out on their own. Someone had to be trying to adjust it without knowing what was going on. If the slug is gone then the radio transmitter is probably out of tune.
You need a new slug and a small piece of rubber band. The rubber band goes in the hole right beside the slug and a good starting point would be about one -one and a half thread up from flush.(that is if your talking about the slug right in front of the final.) Please don't try to tune a radio with out a tune up manual and proper equipment.

How much freon does a 97 jimmy hold

It depends on which engine and which AC system is installed, some hold as little as only 8oz., some as much as 55oz. or more. you could start with around 20psi, that's if your using a refill kit with a recharge gauge that's measured in P.S.I.'s!. Add freon while the engine is running and warmed up to full operating temp, fill through the LOW pressure port only (your refill hose adapter shouldn't fit on the high side anyway), and with the AC system turned ON, if it feels cold (35f-45f-50f with a thermometer) and your compressor clutch is spinning and isn't slugged (spinning and than not spinning than spinning again while turned on) your good, if its not cold enough keep adding by 5psi increments till you get to around 35psi to 40psi. If your slugged just let some pressure back out slowly the same way you would let air out of a tire, but don't use your finger, carefully use a long screwdriver.

Air conditioning

Freon is added to the low pressure side (the bigger line going inside the vehicle). Be careful not to add too much or risk damaging the compressor. Keep the container right side up, so only gas and no liquid will enter the compressor. I recommend letting a professional handle this. We have the proper tools and equipment to do the job properly. The compressor is expensive (professional service is much cheaper), and too much refrigerant will cause liquid slugging and damage to the compressor. Overcharging will also prevent cooling. Good luck!

How to add freon to a 2009 dodge journey

You need 22oz for a "front only" a/c system and 32oz of R-134a refrigerant for "front and rear" a/c system.

The compressor is off likely due to insufficient refrigerant charge in the system. Once the minimum required charge has be provided, the compressor clutch should engage (check for blown fuse if it does not). Refrigerant is added only to the low or suction side of the compressor and only as a gas. Do not invert the refrigerant tank in an attempt to add refrigerant as a liquid! Placing the tank in warm water is a better way to fill the system (raises the pressure in the tank) without concern for slugging the compressor.

I have central air and I was wondering how do you put freon in it because its not blowing out cool air

Is the compressor starting? On the outdoor unit you will see a large copper pipe and a small copper pipe. Is the larger of the two cold to the touch? wet? Just because a central air system is not blowing cool air does not mean it needs freon. If you have clogged filters it cannot do an air exchange. So, I would recommend checking the easiest things first before adding Freon.Most people make the mistake of adding Freon and overcharge their system. In a low load situation you can slug the compressor with liquid and your system is ruined. If you do have to add Freon it indicates that you have a leak. An AC System is a closed system and if it is working properly you should not have to add Freon.

1998 Ford Expendition Eddie Bauer was putting refridgerant then alternator started to spark change the alternator and positive wires but wont charge battery??? The car wont start!!!

maybe too much freon, slug the compresor and things start to move. you may also have had the blow off valve on the compressor blow the excess refrigerant off, and guess what, that stuff will conduct electricity! That's why ac recharging should be left to a licensed pro1

Freezer Unit Isn't Functioning

Inside the refrigeration system alot is goning on. You have to check the pressures low/high to determine the problem. It is easy to say that your unit needs freon but that is not always the case.
here is a list of possible problems:
dirty condenser
dirty evapoator
fans not working
defrost not working
lost of freon
bad compressor
bad compressor valves
lack of oil
super heat off
txv is stuck open/close not sensing
incompatilbe unknown freon mix...

well these are just some of the problems you can encounter. this was meant to tell not fix because each problem needs attention but hope this was a little helpful anyways

My ac also blows hot air, any suggestions

how did you empty your refrigerant?if you broke the system open or allowed it to get the slightest bit of air in it, it will need to be ran into a vacuum before you recharge it in order to make it work properly. in a refrigerant system, 9 parts per million moisture content is enough to slug a compr
