It's a valve that can open an hydraulic circuit befor the water inside freeze.
A TIW valve is a type of safety valve that is used in the oil field. This valve prevents a blow out when drilling for oil.
Ideally, the valve should settle into a single position once setpoint is reached. A hunting valve over-controls, or goes too far, then reverses in an attempt to the correct overshoot, but goes too far, reverses direction again, and constantly repeats this cycle. A hunting valve results in poor control, and prematurely wears out the valve's mechanical parts. Hunting is usually indicative of loop gain too high (PID gain + process gain), or a valve that is oversized for the intended flow, or noisy input signal, or a PID integral term too small.
A soleniod is a device that produces mechanical motion by electrical induction. They are a coil of wire with either a plunger which is drawn into the coil or a plate that is drawn to a metal core. Most small water valves (like for an icemaker) have a metal plunger which is attached to a valve seat. When off, a spring holds the plunger down closing the valve. When on, the coil draws the plunger up and water escapes from the now uncovered hole to the outlet. Larger valves (like sprinkler valves) contain a small valve described above as a trigger device. They contain a diaphragm that seals the main valve and is held shut by water pressure on the diaphragm. When the trigger valve is opened, it releases the pressure and a light spring pushes the valve open, letting the water through. When the trigger valve closes, the cavity on the non-valve side of the diaphragm refills with water, closing the valve.

A relief valve is spring loaded valve that when excessive hydraulic or air pressure is applied it pushes the cylinder in the direction of the spring and lets the oil or air pass through and escape via another hose returning to the hydraulic tank or into the atmosphere in the case of air pressure. Without it hydraulic pipes or cylinders would rupture.
head gasket is bad pull the dip stick to see if their is anti freeze in with your oil or check to see if their is oil in your anti freeze
Yes it can freeze.
Yes, anti-freeze can kill you if you drink it.
buy two gallons of dexcool antifreeze.around 25.00 a gallon.some go for full strenght or a 50-50 mixture,half anti-freeze and half water.locate peckcock at bottom of radiator and drain old anti-freeze out.there maybe a bleeder vavle on manifold to open up so air can escape out.pour in anti-freeze and close valve. job is done but never ever do this when engine is hot.a cold engine will prevent you from getting burned by hot anti-freeze.
50% anti-freeze, 50% water is normal, this can be elevated to 70% anti-freeze, 30% water. It is not recommended to have a higher anti-freeze ratio than this.
Valve Anti-Cheat was created in 2002.
The color of the antifreeze does not have anything to do with the type of anti-freeze. Anti-freeze manufacturers can make their anti-freeze any color they choose. You can use any SAE certified anti-freeze in your 1997 Toyota Corolla.
It's due to the car over heating and it's usually because of cheap anti freeze or too much water in the mixture. (Probably a clogged radiator or a bad thermostat, too much water or "cheap anti-freeze" has nothing to do with it. They don't make "cheap" anti freeze. Anti-freeze is just that... anti-freeze!)
All Caravan and Grand Caravans from 95 -2003 will run happily on regular green anti-freeze. I have had 4 of these vehicles and never a problem with anti-freeze.
if your anti freeze is green. always stay with green anti freeze. if it is orange. always stay with orange anti freeze no ifs,ands,or buts about it.
I need to change the anti-freeze in my 2008 Pathfinder. What do I need to do to perform this task?
You can not. There is an anti-siphon valve in the filler neck.You can not. There is an anti-siphon valve in the filler neck.
