my water temp gauge is getting its reading off the drivers side of the block . am wondering how the temp it reads corresponds to the factory water temp senders input. figure i need a new rad anyway, where is the best place to get one? postons etc. has new ones for $259. believe me.............i had rather have a digital prostate exam than change another -----thermo. forget trying to stuff the "o" ring (thats the size of a shipley donut) that comes with the billet water neck into the housing without destruction.
