The radiator is completely corroded. Running a finger on the fins results in crumble. Turns out he was right all along.
But why did no one remove the radiator? The admiral concludes that it is a pain to dissasemble the radiator on the land rover. So everyone avoided it. Perhaps he is right.VROOOM!! |
Akbars analysis of the problem and the explanation related to the dissembling of radiator are both spot on. Quote:

I hope the painting process does not drastically alter the heat transfer ability of the radiator. See my comments below for the significance of this statement. Quote:

Im inclined to believe that the fan clutch replacement was not necessary in this instance. Unless there was visible damage (leaking silicon oil from the fan clucth or missing fins). The fan not gaining speed with increase in coolant temperature probably had more to do with your radiator than anything else.
Going by the extent of corrosion in the radiator - the coolant was not transferring its heat to the air passing through the radiator fins as it was supposed to. Hence the triggering 'air temperature' for the viscous clutch would not have been reached. Remember, the clutch does not directly sense coolant temperature. There is always a co-relation between the coolant temp inside the radiator and the air through radiator temperature, which is the basis by which manufacturers calibrate the viscous fan clutch.
Im pretty sure that if sam re-fits his old viscous fandrive it will function perfectly now that the radiator is back in business.
