One of Hottest for TU-1D02 thermal wax actuator for air conditioner and compressor for Oman Manufacturer Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Just a guide to fitting new thermostat and replacing antifreeze in the Fiesta fitted with the 1.3 Endura-E OHV lump.
Because the heater valve had failed I drained and flushed out the cooling system as new heater valves dislike dirty coolant plus any disturbances of the hoses & thermostat etc normally cause flakes and rust particles to dislodge and float about. (these engines use iron block & head)
I also fitted a new thermostat as the old one was showing signs of failing in open position which was making engine run cooler than it needed. The cool running engine affected fuel economy which had dropped to 41 mpg from 46.6mpg. Plus the thermostat housing leaked which dripped onto number one spark-plug which started to rust around the plug which then absorbed water which then affected plug operation plus made it difficult to remove. Spark plugs can seize solid in these iron heads (Something to think about if your Endura-E Fiesta or Ka has coolant leaks from thermostat).
Although not shown in the video, I added coolant straight into the head before thermostat was fitted so I knew head & block had coolant present. Easy to add coolant this way as the thermostat is mounted horizontally which means you just add antifreeze until level reaches just below where ‘stat sits. Then once ‘stat housing is secured, you slowly add coolant into reservoir in usual way. Another method is to wedge the thermostat open with dissolvable tablet which allows coolant to flow into engine when filling. Some thermostats have small bleed holes which helps filling but also allows some coolant to flow in the event that it fails in closed position. A thermostat that has failed shut means hot coolant from block & head cannot flow to radiator for cooling. Another reason to look after your car’s cooling system.

How to Calibrate a Thermometer
Thermometers can be calibrated either by comparing them with other certified thermometers or by checking them against known fixed points on the temperature scale. The best known of these fixed points are the melting and boiling points of pure water. (Note that the boiling point of water varies with pressure, so this must be controlled.)
The traditional method of putting a scale on a liquid-in glass or liquid-in-metal thermometer was in three stages:
1.Immerse the sensing portion in a stirred mixture of pure ice and water and mark the point indicated when it had come to thermal equilibrium.
2.Immerse the sensing portion in a steam bath at 1 standard atmosphere (101.3 kPa; 760.0 mmHg) and again mark the point indicated.
3.Divide the distance between these marks into equal portions according to the temperature scale being used.
Other fixed points were used in the past are the body temperature (of a healthy adult male) which was originally used by Fahrenheit as his upper fixed point (96 °F (36 °C) to be a number divisible by 12) and the lowest temperature given by a mixture of salt and ice, which was originally the definition of 0 °F (−18 °C). (This is an example of a Frigorific mixture). As body temperature varies, the Fahrenheit scale was later changed to use an upper fixed point of boiling water at 212 °F (100 °C).
These have now been replaced by the defining points in the International Temperature Scale of 1990, though in practice the melting point of water is more commonly used than its triple point, the latter being more difficult to manage and thus restricted to critical standard measurement. Nowadays manufacturers will often use a thermostat bath or solid block where the temperature is held constant relative to a calibrated thermometer. Other thermometers to be calibrated are put into the same bath or block and allowed to come to equilibrium, then the scale marked, or any deviation from the instrument scale recorded. For many modern devices calibration will be stating some value to be used in processing an electronic signal to convert it to a temperature.
