Heater control valve

That's the heater control valve. It regulates the amount of heated antifreeze to flow through it. They are easy to replace.

Can't that be bypassed? I dont have it on my new engine.
It can be bypassed, when bypassed heated water flows unimpeded into the heater core, if the heater doors and controls are working properly this usually isnt an issue. The part is however easily installed so as long as the vacuum that actuates the valve gets there then there isnt any reason not to have one.
