The Jiggle pin allowes any trapped air behind the thermostat to pass through. Without this the engine could overheat. The thermostat uses engin coolant to melt a wax capsule and allow coolant to pass. The engin could be at operating temp and the thermostat would not open due to air being in contact with the capsule instead of the actual coolent. This would most likely lead to an overheating engin, and damage.
The verb to jiggle has the related adjectives jiggling, jiggled, and jiggly. The adverb form is not listed, but it would be of the form jigglily.
i believe it is called oscillation
Yes. The homophone for thermostat is "thermostate."
The spring in a clothes pin exerts a force that squeezes the two arms of the pin together, creating tension. This tension keeps the pin closed and securely in place.
The red button on a thermostat is often a reset button. Pressing it will reset the thermostat to its default settings. This can be helpful if the thermostat is not functioning properly or if you need to start over with the programming.
If it is the 4cly you need to remove your intake, unbolt the thermostat housing from the side of the block (it will be the one with the radiator hose going to it) pull the thermostat out. When replacing with a new thermostat MAKE SURE YOU INSTALL IT WITH THE JIGGLE PIN FACING UP!!!! I repeat JIGGLE PIN FACING UP. Burp the radiator system well and your done. Good Luck
Most thermostats have a Jiggle pin. Its function is to allow trapped air past a closed thermostat as a build up of air in front of the wax capsule could cause engine damage. The wax capsule relies on coolant to relay heat to operate. If air was surrounding the capsule and the engine was at operating temperature, the stat would remain closed and cause the engine to overheat.
Follow the top radiator hose to where it enters the engine. The thermostat is in that housing. You will need a new gasket. Ask the parts guy how the thermostat is installed. Many thermostat have a "jiggle pin" which most be located correctly.Don't get wrench happy tightening up the thermostat housing fasteners. The proper torque on those fasteners is not much.
The jiggle valve's a small hole on the thermostat itself (not a separate part). It's merely there to help free the system of trapped air. Follow the hose from the top of the radiator to the motor and you should find the thermostat housing. Removing the housing will reveal the thermostat and at the top of the Tstat should be a small hole -- that would be the jiggle valve (if your thermostat actually has one).
You have to install the thermostat with the jiggle valve in the 12 o'clock position.
Follow the water hose to the distributor on the DOHC 4 cyl 1.6---the housing to be removed is a few inches from the distributor. Remove the distributor cap and other stuff if necessary. The Jiggle pin of the thermostat must face straight up when installed. Folow the thermostat included instructions. Acutemoon@phreego.com
allows for the thermostat to always be open never fully completely shutting close. The old ones closed complete, then hoses blew, now you get the trickle and warning you have a problem. The jiggle valve is a big help in bleeding air when filling an empty system.
Remove the Air Intake Box so you can see in below... there is a pipe running right into the bell where the thermostat is housed. There is one bolt that you need to take remove (it is to the right, below the distributor, it goes into the engine block). Then there are the other 12 mm bolts on the bell of the thermostat housing to remove. After removing those the thermostat should be able to come right out. When replacing i would recommend getting a replacement thermostat with a jiggle pin...

The thermostat at the engine in a 2000 Mercury Villager is located Êon the right passenger side near the middle. You should look for the jiggle valve on the thermostat that should be facing up.

The pin is called a "jiggle" pin. It's there to allow the system to bleed off any air pockets that might be sitting above the level of the port on the T stat. The pin should always be pointing towards the top of the engine. Rick I'm a retired ASE Master/L-1 Technician. I still keep current with the latest automotive technology.
