My 240 Diesel (1986) started to overheat, it takes approx. 15 minutes to reach the red zone (it's winter now and below freezing outside). When I stop the engine and check, the motor is hot, the radiator is completely cold everywhere. I replaced the thermostat yesterday, it did not help anything. The system is filled with a blend of antifreeze and dist.water. There's no loss of water, the sytem did not seeem to leak anywhere. The hoses are in good condition, but the radiator (all metal modell) is as old as the car. It does not leak but the little copper lamells are falling out almost everywhere. Is it possible that the radiator is completely blocked,so that the water is not circulating at all, or do you think that there's something else wich could cause the problem?
It's the second time that I drain the whole thing completely in a week so I got a bit of routine with this part so changing the radiator would not be such a technical problem, but I would prefer to be sure that this is the problem before spend all my savings on buying a new radiator. It would be a great help if someone had an idea about it.
Thanks Andrea
