So i just installed a grill block because everyone is doing it. anyways without it the car runs around 195-198 in most conditions. fan never turns on. now with the grill block, other than it running a bit warmer which is expected, it seems like the cooling fan turns on way too soon. usually i see the coolant temp drop after it reaches 202-204F. im using scangauge II for the coolant temps.
is there any way to have the fan turn on a bit later, or i should say hotter? maybe in the 210 area or even higher?
mine doesn't come on until the temps are at somewhere around 220 or so. not sure how your set up is but I think you can get different temp switches for the electric fans to kick on at different times. with t-stats runing 195 or so I think 202 is really low for a fan to be coming on. you may be killing all the advantages that the grill block is giving you with that fan.
not sure about on your vehicle. still seems early to be coming on
Be the change you wish to see in the world
forgot to mention this is for a 98 civic hx. i've read somewhere that the fan should come on around 235 but the manual says 203. maybe a different year civic's temp switch can be intergrated to change when the fan turns on.
