I know that the torque on the 1991 4 Runner V6 is around 180lbs of torque and the threads have adhesive applied to them. HOWEVER, in my case my problem is just the opposite. My truck lost the bolt and trashed my radiator and I now have to order a new one. - You might find out by calling a dealership if the bolt is LH or RH... This might make a difference... NOTE: Make sure you put set torque properly when you replace it and put adhesive on the threads... If you don't it spins out and slams into your radiator at high speed...
try an impact gun, or rest a breaker bar against the body or something and use the starter
