temp gauge reading fluctuating

[lee481]

mga bro, greetings!

got a prob with my temp gauge. last time sumasabay cya sa rpm then bumalik sa normal. this time wla cya prob as long as ur running below 100kph but if you keep ur speed sustained above 100kph for a period of time and of course sa nlex ko lang nagagawa to, eh tumataas na cya pero weird kc pag ineutral ko cya while running e bumababa din cya. wori ko lang kc na mareach nya max temp reading while running dba coz ishutdown ng comptr box ang engine for safety. i need your help mga bro if you have any idea to solve this problem. btw, civic esi pla car ko. thanks!

Check the level of your coolant sa radiator at sa reservoir, pag okey naman the most common cause daw ng high speed overheating is restriction sa coolant flow usually a clogged radiator. Cavitation of the water pump at high speed is another cause.

One way to test is:

With a cold engine disable your cooling fans. Start the engine and let it reach normal operating temperature (your engine will heat faster w/ disabled fans).

Turn off the engine and feel the radiator for cold spots, if positive clogged radiator mo. Or else drain some of the coolant, and look for deposits sa loob using a flashlight. But the best thing to do is have your cooling system checked by a good mechanic.

Please dont forget to return the electrical connection to your fans. Watch out baka po mapaso kayo.

the computer will not shut down the engine when you are overheating... so be carefull if tuloy tuloy parin sya nangyayari.

Kumbaga s tao, maaring kulang sa dugo (coolant), may sakit sa puso (water pump) o barado ang mga ugat (restricted coolant flow). So pag medyo strenous na ang physical activity ay tumotyope na, check-up kaagad baka matigok ng wala sa oras.
