The simple answer is: Yes. It can free up the engine and I'm sure it wont cause any harm. I've used this method several times in the past and recommend trying WD-40 first. But really any penetrating oil will work just fine. Heck, I've even been successful with used motor oil! But I do not recommend using that because there are fine particulate in it that may cause damage.
If a product like wd40 does not work easily Get a new gas valve, Why risk loosing your house over a 100-200 dollar part. If the gas on your car was stuck well you get it.
Before soaking metal jewerlry in WD40 to remove adhesive, test on a small area. This will prevent you from ruining the piece if the WD40 removes or damages the finish.
no it does not, if anything it will help it.
Well, you can get a new one. Or you can go underneath and soak it in WD40, go in the vehicle and try to move it, then soak it again and let it sit for awhile. Repeat and if it doesn't come loose, It may be rusted together, take it in and get it replaced.
You can use WD40 to help the squeaking computer chair. Just spray the WD40 on the bottom of the chair.
wd40 might help. I tried WD40, but it didn't solve it. well I'm sorry i can't add to that
Start the engine and spray WD40 on all vacuum connections. When you hear the engine RPMs increase you have found a leak.
A single can of WD40 is small enough that it does not require special storage, except that as an aerosol it should not be stored near a heat source such as a boiler or furnace.
no, door locks have nothing to do with check engine light.
spray with WD40 if that doesn't help replace the door lock
It will probably die - and I do NOT intend that to be used as an invitation to, or to help, gratuitous cruelty.
Try warming the car by letting it run for a short time, but not letting it get hot. Also something like WD40 sprayed down in there overnight will help. Never Use WD40 unless you are absolutely sure the sensor is U/S. The silicon in wd40 will adversely affect the O2 sensor operation.
