I did a TB coolant bypass and I was wondering if I can just block the heater valve to intake manifold hose? I assume its alrite because it was used to warm the TB but will I have any adverse affects?

 

The heater hose coming from the front of the intake is the hot water line for the heater as well as the TB. If you bypass the TB, and still want heat, you have to connect that back up to the heater valve. Or you can bypass the heater valve too and run it straight to the heater core.

If you want to eliminate the heater too, feel free to route the line from the intake straight into the return to the radiator. If you want to block it all together, pull your t-stat and drill a few bypass holes.
