413 intake manifold bolt holes

[DaPoz]

I have a possible coolant leak I am needing to address.
Can someone share exactly which if any intake manifold bolts go through to coolant passages on our 413's, circa around 1964?
I searched for a flow diagram online and found notta; nothing in the manual or archives..

Many thanks!

No intake manifold mounting bolts on a 413, nor any other Chrysler big block wedge engine, enter the coolant passages.

And none of the other bolts on the manifold, like the coil mount, carb, and choke go into a coolant passage as there are no coolant passages in the intake on a 413.

I'll bet you have a leak in a hose, radiator or radiator cap that's leaking and it's blowing coolant back on the intake.

Here's a picture of the intake manifold mounting face on a big block Mopar engine.
