Here the follow up of the rust,trash,crud or stuff getting out of the cooling system.

R L Chilton : I flushed the engine with the normal waterslough and indeed another amound of the things above came out.

Kdancy : with the presure washer a couple of days later again new crud came out. Indeed dry the engine inside and outside with compressed air. The total proces takes a lot of time !! Several hours and you get very dirty and wet!!

Walts garage - 53 : You talk about another engine ?? Perhaps 1936. From 1937 on the waterpump is no longer on the head.
I do not know where the rubbers are you talk about ? Please can you give some more details ?

Ken U- Tx : My question is : Which cooling fluid is the best ? In my case Anti freeze is not important. In the winter the car does not come out of the warm garage.
Anti corrosion and waterpump seal lubricants are inportant. With deiononized water both things are not in the fluid.
What gives the best cooling, that's important with this old engines.
In England someone told me that some coolant fluids will give an engine tempreture 10 degrees C. lower??
Also there are products you can leave in the engine for a longer period.

Please, some good advise about the cooling fluid ? I hope as good as my question about the rust. The makes in the USA or in other parts of the world will be sold in the Netherlands?

    Henk-
    yes, it is a nasty job! But it is the only way I have found to get all the crud out of a block, A steam cleaner is even better if one has access to one.

    No, I was talking about engines 48 to 56, not splashers. They have a water tube behind the water pump that sends water to all hot spots, mostly valve seats. Walt.

    An HET member here in NZ who has been in the radiator business for decades told me some time ago that the only thing that should go into the radiator with the water is an egg cup or so of soluble oil (as used on lathes) every so often. This will prevent any rust developing.
    After the problems I had with radiators failing a few years ago while using bottled additives, I have taken heed to his advise.
