temperature drops

**dyzzl3** · March 9th, 2011 10:46 AM

The temperature drops whenever I turn on the AC. from normal temps (about midline) it drops to about a little above C or about 1/4.. When I turn the AC off, the temp goes back to normal. I dont know if the problem is in the sensor for the temp gauge or if its a bad thermostat/valve or something. I recently cleaned my radiator and flush out the coolant but it did not solve the problem. anyone? thanks.

sir don't worry about that muna as long as hindi ka nag-ooverheat.

sir baka wala ka na termostat valve... kasi kung meron It should be consistent...

one in a million itong situation mo sir ah....

tama po na as long as hindi overheating no need to worry...plus, as long as hindi rin overcooling....

pero what i have in mind is: the thermo switch could be of low resistance. it now requires a lower temperature before the bimetallic strip inside the switch will open as compared before...try replacing the switch.

i'm not sure about it not overcooling because it sometimes reaches the C mark and that's what's worrying me. i might be running on cold conditions making the ecu think the engine is not yet warm and stuff.

also as a side question, does anyone know if honda/acura use the same components for thermostat and all that stuff? can i use the thermostat for civics sold at the local dealership? i won't be going home to the states till may or june so if i can buy a thermostat here then that would be great.
