looking for neat way to block car coolant outlets

[steveo3002]

ive got a inlet manifold off another model that i want to use , it has a couple of coolant outlets that are unwanted

wondered if theres any proper blanking thingys rather an a couple of inches of hose with a bolt in it that looks rough

Rubber blanking caps are available that simply fit over tube stubs with a jubilee clip,
depending on the model the old Ford Essex v6s used to often have one on a stub coming out of the water pump.

Looped pipe between the outlets?

Cut the outlet off, tap the hole and screw in a plug or bolt. If you want to re-instate it then you can screw an outlet in instead.
