    hi guys, i have a 4k engine in my owner type jeep, my temperature gauge is not working so bought i new one. i had it replaced yesterday. may i know what is the normal operating temperature of this type of engine or it applies to all engine types? i dont have a baseline data about temperature of this engine because i bought this unit in 2nd hand, 3rd hand rather... and temp gauge is not working as well. so masters, can you tell me what is the normal operating temp pls.. so that i will be aware if it exceeded/overheating..

    thank you..

    good day masters, not really an actual one but since the gauge i bought is just the normal one.. this only cost me 250 pesos, its grid starts with 120 then 150 then 190 and so on... i really don't know if it's in celcius or fahrenheit. i ran for about 15km today and it did not even move a lil bit. i just assumed that the water temperature did not reached 120 degrees celsius or fahrenheit because im not really sure what is the label of it.

    i hope someone could share their ideas about this... thanks in advance...

    On average, I think it should be between 90-110 C which is 194-230 F.

    if the gauge has no numbers on it, midway would be a good reading. but in heavy traffic on a hot day, slightly more than halfway is still ok. and i would start looking at the needle more, if it starts creeping to 3/4 of the way..
    my 83 centavos' worth..

    It did not move a bit, maybe because you removed the thermostat...

    the thermostat causes faster temp rise in the engine block. you can usually see the needle move after only 2 km.. but if the thermostat is removed, it would take considerably more time for the needle to start moving , mebbe 2 to 3 times longer.
    btw, check the connections... baka hindi kunektado..
