If this is then correct I can't see any reason why the secret hose can't be removed and blanked off, which now debunks by theory in post 44.

I shall now when time permits, blank this off and remove excess junk from the engine bay.

I initially had concerns that the oil cooler was sitting in coolant but not in the coolant flow.

So all this seems to be more relative as to the radiator that we put in. It seems like the coolant is going to flow around the oil cooler regardless.
If we have early type radiator then we use hose and flow around the back of the engine to the radiator.
If we use late model radiator block oil cooler.
Someone has changed my radiator at some stage to a late model.
I will leave my oil cooler blocked now.

This was all stated back in post 39

I too puzzled over the design for many hours trying to improve it.

Just to confirm, on EU2 models, the oil cooler blanking can be installed with no adverse effects.

By design the only improvement that can be done is possibly contact time of coolant to oil cooler surface time.

Hence this design... further I now installed an elbow onto the cooler to force cool water from the pump through the cooler. Fins on the outside has also been added.

This is basically a pipe containing hot engine oil and thin pipes inside with coolant flowing through it. I wasn't happy with the original design where water could choose the path straight to the block instead of forcing it through the cooler first.

Material choice is the other improvement over stock.

That is a pretty impressive piece of cooler there. How about manufacturing them.

Here here!?!

Mods.

As this is now more about the block, can this be moved to Td5 Block?
Or a new thread be started?

Will.
