ezwong2002,
dude, u said u hv the adaptor for sensor...
how can i get it from u??

well done... :)
any pics??

i`ll snap some pics by tonight . anyway what are the ideal readings for the water temp eh ?. i mean what are the ideal operating temp for a car ?. and what is the max temp for a stock paper gasket ?. 100 celcius ?

 

[sunnyboy]

as long as the reading not over 120c, it's safe, if ever exceed that level, stop ur car

 

[vestax]

so the max temp is 120 and the average is 80 - 90 ? , cause my readings are 80 - 90 c . hope that is okay . by the way im driving a turbo .

 

[sunnyboy]

yup, normal......

here are the pictures :
sorry abit dark , cause no light .

wiring damn messy , i had to use the home mini compo audio wire .

heheh...nice :)
mine still not done...have to buy adaptor...but have to postpone this project coz i hv dateline to meet...haih..hehhe :(

103 degrees celcius

i think the maximum operating temperature of the fluid for the engine cooling system in all motorcars is 103 degrees celsius, this is because when water has been mixed with 50% coolant by volume in addition to being under pressure, the cooling fluid will rise up to a temperature of 103 degrees celsius before the pressure release on the radiator cap opens.

if the temperature reading rises above 103 degrees celsius, it may indicate that the cooling system has been contaminated by other fluids which are able to reach higher temperatures before turning into a gaseous state. oil is an example of such a fluid. allowing the engine coolant to be at this high temperature to be circulating around the engine will cause the electric fan to work more often resulting in reduce life-span of the electric motor and more frequent 'drag' (increased amount of work) for the charging system.

this is just what i understand from the liquid state and gaseous state of water (steam). pure water boils at 100 degrees celsius and just beyond 100 degrees celsius it turns into steam. mixing with 'engine coolant' will raise the boiling point of water a little and having water under pressure such as the closed system in the radiator will also raise the boiling point of water by a little.

i will check this information again and update this if i am mistaken.

Need help

I just installed the temp gauge, i tap the + wire from the cigerete fuse box there,ground it to the battery negative terminal,light not yet connect,wired up the sensor using back my previous sensor,im driving nissan terrano, why when i turn on the key,it shoot up to 120? then i turn the key to light up the meter,it goes back to a respectively temperature, then when i start the car, it slowy increas,as the reading is increasing until 100 degree, so got any problem? as i dont know my car spec as well...thanks!
