DOES ANYONE KNOW WHAT THE NORMAL RUNNING COOLANT AND TRANSMISSION TEMP IS SUSPOSE TO BE....IM RUNNING 205-215 DEGREES F FOR MY COOLANT AND MY GAUGE IS UP TO H MARK BUT NOT TO THE RED MARK AND TRANS TEMP WITH THE AUTOMETER GAUGE IS UPWARDS OF 250F WHICH IS AS HIGH AS THE GAUGE READS..IS THIS NORMAL I HAVE REPLACED THE ENTIRE COOLING SYSTEM AND RAN A DYNO EMISSIONS TEST AND PAST WITH FLYING COLORS SO IM GUESS ITS NOT A HEAD GASKET, BUT I FEEL THE MY CAR DYING ..I CAN'T FIND NISSAN SPECS ANY WHERE... O YEAH ONLY ENGINE MODS ARE OBX HEADERS WITH THE DOWN PIPE AND SHORT RAM AIR INTAKE

 

why are you yelling?

 

sorry for the caps im at work and i default with caps....but i have jus spent enough money and time on this problem that no one seems to have a logical answer for

 

I just had an xterra at work that was running around 219 degrees and it turns out the radiator was partially clogged. You say you replaced the "entire cooling system" a few more details here would be good. What parts exactley have been changed? Also, year, auto or 5 spd, mileage, the more details better chance of getting a correct diagnosis.

 

radiator upgrade to custom high flow alum.,fans, relays, temp sensors,temp sending unit, water pump, t-stat,hoses, and i use my bg flush machine twice so far...i also used the modis to check fan speed operation and watched them to make sure they are switching on when they should, but the reference i found for temp specs was in alldata for the fan speeds and operations and they check good. when i turn the heat on my gauge goes to the middle then in traffic or red light it creeps back up and before the light turns green it almost goes redline heat.and when driving some times creeps alil high on 80 Degrees F day...I have all checked and clean the condensor to make sure it was clear

 

sorry i forgot to say this is the second radiator because first my stock rad cracked at the head so i replaced with oem from dealer then still hot so i thought i might try the alum high flow ...this is all still while my gauge really high
