car 2wd sierra sapphire cossie, went out today, after doing oil/filter/coolant change yesterday, also fitted header tank and swirl pot, went a run brake kickback from peddle stopped but slight judder when hot, so could be warped, came back coolant dripping on ground, bad drip, looks to be from pulley bearing on pump,this is a cast pump, i take it there is the usual little hole in body of pump to show shaft seal gone? if so is there a difference between 2wd and 4wd pumps as it has a cast iron block 4x4 and 2wd parts, i dont know which is which,so how do i know what pump is fitted and does anyone on here sell them?
