Possibly daft cooling system Q

[Pupp]

Anyone know the reason why the top coolant hose to swirl pot is designed with an angled entry so that the hose is effectively the highest point in the system… keep thinking there should be a bleed point where the hose elbows as air must get trapped there (maybe intentionally)?

[Johno]

I guess it may ensure that trapped air is held away from the inlet manifold in the elbow therefore eliminating possible airlock issues ?

Don't know what the set up is like in more mainstream used SD1's etc ?

[GreenV8S]

There is probably a much more mundane reason, like making sure the top hose clears the exhaust.

[Pupp]

When I said 'top hose', might have misled... this is the one that comes off the 'stat housing and loops to the swirl pot. Just seems an unecessary air trap on an engine that's already prone to cooling difficulties

[f@-pots]

S'funny you should say that Pupp, having just rebuilt my engine and suffered the afore mentioned airlock I too was thinking 'whats the point of having a swirl pot/filler that's not right at the top of the system ?
