Coolant crossover quick question... Alright guys, I just completed my heads/cam swap, and when lifting my radiator out the small coolant hose that connects to the throttle body on the passenger side got snagged on the A/C line and broke the plastic nipple that the hose connects to on the radiator, right off.
I repaired the radiator tank by plugging that hole and sealing it up good with some high strength quarter panel glue. I know I can just bypass the coolant around the throttle body, but since I blocked this hole off in the radiator, can I just take the T that goes from the driver's side of the TB to the coolant crossover tube and T it into the small coolant line that goes from the overflow tank to the radiator?
Any help is appreciated. Thanks

Tapping the water pump makes no sense to me. The objective is to vent steam, and steam rises. By redirecting flow downwards, steam will still be trapped at the highest point in the system. A better alternative would be to plumb to a low pressure / low velocity point of the radiator / overflow tank at a place higher in elevation relative to its exit from the block.

That line has a definite coolant flow, you can see it when you're filling the radiator with the engine running (after the thermostat has opened). And don't connect it to the overflow tank line, that's controlled by the valve in the radiator cap.

You can't tee it into the overflow tank. You will fill the overflow tank with coolant while draining the block. It has to go back to a pressurized part of the cooling system.
