I've recently put a new rad in my sportrak. It seems to have developed a leak from the heater matrix pipe next to the thermostat housing. (the one that has the matrix hose with a small coolant line to the injection manifold) I've tried new jubilee clamps, put the original pressure clamps on and the leak still persists....
could this be a simple issue of new pressure clamps (i think jubilee clamps "pinch" and cause a leak)
Any advice is greatly appreciated.
