Most likely worn headvalve Part# 882927 not expensive and available thru However you could try cleaning and lubing the headvalve. Sometimes debris will enter the gun thru the air hose and lodge in the head. Use white grease or silicone paste. Good luck.

How to flush a gmc heater core

Dear Tim
Disconnect the heater hoses from the engine block.
Using some steel or plastic pipe of the right diameter to fit inside the hoses.
Clamp the pipes inside the hoses, and attach a garden hose or a compressed air hose to the pipe to blow the heater core clean. Remember, the normal pressure that the core is designed for is about 15 # per square inch, so either normal household water pressure or an air compressor can blow the core to pieces, so be REALLY gentle whilst blowing it out.
God bless your efforts.

Air want blow out dash vent only the defrost vent

You should be able to get enough air pressure from an air compressor to do this. If you need something to get further in then you can use an attachment to give you more length. Attaching a piece of rubber hose to the end of your attachment would be a cheaper way to go. You can pick that up in any length at a hardware store.

I have a hose with a filter attached to it on the right side of the bike and every time i start the bike oil flows out of it?

check the oil level and make sure its not over full. the hose with the mini filter is a crankcase breather, if there is too much oil, it could cause oil to flow out the breather. It is possible that the rings are worn or broken causing blow by or extra crank case pressure. The hard shifting is usually caused by a dragging clutch or the clutch being out of adjustment.

Washers keeps filling and overflows does not agitate

Your washer has a hose that goes from an air dome on the side of the tub to a pressure switch in the console. As water fills the tub air pressure increases to the up the hose to the switch and that is how the switch regulates the amount of water in the tub. More than likely the hose has either come off the switch in the console or the switch has failed. You will need to gain access into the console and check the look for a clear rubber hose that attaches to the back of the water level switch and make sure it is still attached. If it is not reattach it and try it again. Sometimes an out of balance load will cause it to come off. If it is still attached you can remove the hose from the switch and blow through it to make sure it is clear from obstructions. If the hose is clear and detached from the switch you will need to replace the pressure switch. Thanks and hope this helps.

We tried adding freon to our 98 Montero AC unit but when we attempt to it says the it is at full pressure and will not let us add any but it is only blowing hot air with the ac on, so we do not think it...

Hi, if you have full pressure (40-50 PSI on low pressure side with engine running A/C set to maximum and blowing) you have enough pressure, but there is air in the system which degrades the refrigerant leading to no cold air. To remedy this, you must completely discarge the system and refil with new R134a which has the compressor/system oil added to it.
To discharge the system, shut off motor, attach your filler hose to low pressure valve and allow system to drain. (squeeze handle if you have that type filler hose) Allow it to drain until no sound of escaping air is present. Be careful not to have the end of hose facing you or others, wear gloves and have some shop rags laid down, pointing nozzle toward rags, that stuff can damage paint and skin and may be cold when escaping. After system has completely drained, start the refil process with engine running, A/C on maximum, blower on full. After about 1/2 of the first can of R134a or 1 full can, your compressor should kick on. Continue refilling with 3-4 cans total (about 3 LBS total) until you have a reading of 45 or so PSI. After each can, allow refrigerent to cycle through the system about 3 minutes to obtain an accuret pressure reading. Pressure is relavent to outside temperature also, optimumly the ambient air temp. outside vehicle should be between 72 and 80 degrees F. for proper reading. That should get you blowing cold air again!

Seems to over fill the load with water and goes to ol at end of cycle


The water level is determined by a pressure switch. The pressure switch is located near to the control module and attached to thin a rubber hose that goes inside the tub. Check the hose attached to the pressure switch for blockage. Blow into the hose and see if the pressure switch is clicking.

If replacing the pressure switch does not help, then problem is either a stuck inlet valve or a defective electronic control module.

A defective pressure switch is the most common fault that will cause this problem.

Furnace will not run indicator shows 3 red flashes with the led. According to the book this represents a pressure switch open with inducer on error. Any help appreciated

There is a pressure switch on the inducer motor with a rubber hose attached to it. Make sure that this hose is attached and is not cut or leaking, it's much like a vacuum hose on a car. Also make sure that the inducer motor is operating normally, nothing blocking the flow of air through the flue.

This is a symptom of a pressure switch problem. Open the console and double check the pressure switch (located behind the water level knob) and make sure the rubber hose is still attached. In many case, this hose vibrates loose and comes off the pressure switch. Without the hose attached, the pressure switch never senses the change in pressure from the wash tub required for it to be shut off. The end result: your washer continually fills without shutting off. If it is a simple hose problem, you can prevent this from reoccurring by placing a small zip tie around the air hose at the point where it attaches to the pressure switch. Do not over-tighten as you may damage the switch fitting. Just make it snug.

If the air hose is still attached, and the electrical connections are still attached, replace the pressure switch. I could not find a part number with the model number you listed this under. Please double check you model number again and post back, so I can assist you finding the correct part (if needed). I hope this helps you. Let me know if you have further questions.
