    Coolant temp high with a/c running?

    The a/c fan does come on automatically, it is the engine cooling fans i have on a switch. I also have a digital monitor that reads the coolant temp, voltage, and o2 data. I originally tried the thermistor, but kept having issues, so i bought a switch and it has worked well. I will say i found...

The heads as far as I know have...

    Coolant temp high with a/c running?

    My temp on the 1uz usually runs around 87 to 95 degrees even on the hottest days with my 3 core alum radiator and duel fan setup. But when turning a/c on it climbs to sometimes 104. Is this normal. The compressor is always on i will add when the a/c button is pushed . Im not sure if the...

    1uz over heat issues

    So i havnt changed the thermostat, but what i did do was remove the radiator shroud that i made from a piece of aluminum. I had it there for directing more air flow to the radiator,but i think i may have been causing heat issues. Not sure will re Evaluate as the temperature outside goes up...

    1uz over heat issues

    thank you for the technical information . to make the fan location clear. the fans are in-between the radiator and the engine not the radiator support. they are pushing air thru the radiator and a/c condenser and out the front grill. i am going to pull the thermostat this morning and check to...

    1uz over heat issues

    the fans are behind the radiator , i did 100% verify the fans are pushing thru the radiator. i have a replacement thermostat. i wanted to try the trd 70 degree or the mits 76 degree option ,but haven't ordered either. I do have a ls400 thermostat, but skeptical it will change anything especially...

    1uz over heat issues

    So 95 ls400 is overheating at idle. I have a 3 core radiator , and i did have just a 15" electric fan bolted directly to the radiator. It did ok ,but on hot days is would get up to 240f at idle. So i got a mishimoto dual fan setup with a shroud thinking it would help direct the heat better. Well...
