stag cooling system

[MikeParker]

My apologies to anyone offended by the word used to describe the continual interference in the most condescending manner possible by the personal protector of a single member of this club.

It is almost like Mr Wheelz has no voice of his own and must be protected by his own personal moderator. Desperate to prove that everyone else is trying to pick a fight

To be frank I am fed up with the whole damned thing so time for MikeParker to stop trying to start fights and for me to behave in a more adult way.

Lets keep this to a cooling system discussion eh

Richard,
Point taken. I will leave it to the other mods to keep control for a bit..

Good idea. Let’s stick to the facts and experience of our experts.

When the cars were new, most owners were not that keen on lifting the bonnet though.

That describes most car owners today. I know plenty who do not know where the bonnet release is located.

Neil,
It would be interesting to know if the designers of the engine attempted to produce some sort of restriction in the engine block casting to reduce the flow to the forward cylinders. I have tried to poke around the pump outlet into the block to see if there is any separation of flow at that point, but there does not seem to be any from what I could see. In the absence of that, I guess the "cold" water output of the pump would tend to take the shortest route back to the thermostat housing, i.e. via the forward cylinders.

There will be very little flow towards the front of the front cylinders as there is no outlet for the flow at the front of the engine apart from the air bleed hole in front of the inlet manifold.

Very little flow would be needed here as a large percentage of the flow would be directed between the front two cylinders from the pump outlet.

I read somewhere that the development engineers of the Stag engine used glass windows in the heads and tea leaves circulating in the coolant to show the flow. It wouldn't have needed to be a running engine I suppose, a direct drive to the jackshaft to drive the pump would have done the job.

I believe this is the reason that the holes in the head faces don't match up with the holes in the top of the block, some of them are reduced to holes of just a few mm in diameter, and some are blanked off. This would direct the flow more to where it was needed. Its still a complicated way of doing things compared to the Rover V8

Many coolant designs went from front to rear.
Our stags coolant flow does.
later designs force coolant across the combustion chamber , from inlet towards exhaust.
just saying, as they say.
