Temporary heater core block off ???
 

Can I run a hose from the inlet manifold that normally goes to heater core directly to the heater hose inlet on the radiator to cut the heater core out of the circuit until I have a chance to replace it.
I cannot see why not but thought I should ask first.Seems easier than blocking off the radiator and the inlet manifold.

I have one of my trucks set up like that.

Pipe plugs instead of hose barbs works as well.

Only thing you mite run into is the inlet side of the heater core is 3/4 hose and outlet is 5/8. (Or the other way around)
I just did mine last week and used an old hose fitting ( the one that goes into the intake manifold) put the 5/8 hose on the hose end and the 3/4 hose on the threaded side (1/2 pipe) couple clamps instant hose adapter.

I've found that a good hose clamp can seal a 3/4 hose on a 5/8 fitting, they're not that far off.

Or, the other direction, I've found a little bit of heat, a little bit of lube, and some force can stretch a smaller 5/8 hose on a 3/4 fitting.
