Just google "TPI heater valve hose routing" and it will be in the top results.

You can't get rid of the throttle body; that's a key component of the car. Are you talking about getting rid of the whole TPI system and turn it into a carbureted engine?

Well your thread title is Heater control valve and throttle body delete.

It should say throttle body coolant bypass.

He's kind of new to 3rd gens and TPI systems I believe.

Re: Heater control valve and throttle body delete

Yes, that’s what I meant the coolant lines to the throttle body and the heater of control valve maybe I’m the one who is on drugs. Everything I searched only shows how to delete one of those not both of them together and how the hoses run.
