Do I need to bleed the coolant after replacing the heater valve

I plan on replacing my leaking heater valve which is on the firewall up high. I don't plan on draining the system because the valve is higher than the radiator, but some fluid will come out.

When I put the new valve on should I bleed the system like I did when I flushed the coolant?

 

On the 6cyl, I have never bled the system when replacing the radiator or doing a t-belt. I have heard most TOYOTA coolant setups are pretty forgiving and the air moves out of the system after a bit. I, myself, wouldn't bother. You can do it later if you have heating issues.

 

Don't know how you bled when you flushed.

But I'd just park up hill and run it without the radiator cap. Or you can get one of those fancy funnels. Top off as needed.
