    Default car running too cold what the hell

    hey guys a little while back i had my bt 20v over heating i have sence done research and sam q has helped me out on how to run the cooling system, i have run my cooling system exactly the way sam q has said and also ran the bypass from the top of the water pump to the top rad hose, my issue is around town and at idle it sits at a perfect temp of about 80 deg, as soon as i start to drive or around town it drops to 70 odd deg, but if i hit the high way she will drop to 45 to 50 deg which is shit. now i have a koya alloy rad, ive checked the thermostat and replaced that with a new one no issue there.i have sence put a welsh plug in the top rad hose with a ten mil hole, this has helped as it sits a 80 deg for about 30min but then it starts to drop and eventually and hits 45 deg. i have just purchased an alloy pully kit with an under driven water pump pully, do you think this will help as im thinking the cars water pump is spinning too fast as my car sits on 4000rpm at 100klm as i have 4.7 diff gears?????
    any ideas on this

    is the temp gauge taking reading in the right spot???. all symptoms suggest a stuck open thermostat but you did that??maybe radiator is too efficent and when the thermostat opens it gets a rush of cold water. maybe a hotter thermostat will help

    yeah its a new gauge vdo and its picking its temp from the rear of the head on the passenger side were the top rad hose is ment to come out of, the prob is at idle it sits at a perfect temp of 80 deg if i put a hotter thermostat in wont it over heat at idle or is this wrong????

    sounds thermostat man. might be worth checking. did you use genuine one? im mechanic and refuse to use aftermarket because ive been bitten too many times.either dont open or stay open or too slow to react

    dont think slowing water pump will help,temperature is controlled by thermostat.do one repair at a time to eliminate one or the other.
