Hi Guys Again Just a quick question I want to ask. I brought a new 3 core radiator for my VL Commodore (mine is auto). I had a cracked head for the second time so partner re bulid my motor. So he read get a 3 core. So got 3 core but just that the temp goes half way. Im worried about that, as before it wouldn't go that high. Has coolant in it and have replaced the themostat in it. But still runs half way. I brought the radator and partner put it in the car. He says it doesn't get hot, put hands on the hoses and doesn't get hot. Only been in the past 2 weeks! Worry or not?
