My 1996 Prado is a big ass mess with a blown head gasket (confirmed by a mechanic who did a smoke test?-I think). But no white smoke and no over heating. I drove it a short distance today and noticed it wasn’t consuming coolant like I would suspect for a vehicle with a blown head gasket. Turns out the top radiator hose is hot but bottom is not (as well as the bottom of the radiator was not hot). The coolant was nasty. I flushed it 3 times but still the same problem. I ran it with out the cap and rev’d the engine. This would over flow the radiator into a funnel. So I assume the water pump is working. I’m guessing the radiator could be clogged in places from the nasty gunk that was in my overflow reservoir? Dunno, kinda at a loss.
