DIY: TB Coolant Delete

Junior370z · 05-20-2009, 05:19 PM

Is it possible for you to just tie the lines coming from the "in" and "out" of the throttle body together with a barbed hose coupler? I know it won't be as clean, but it will be much easier to put back to stock if anything happened. That would work right?

Also can you feel the engine to be more responsive? You know like when you first start your engine and drive off before everything heats up.

Thanks in advanced.

That would work fine....

I believe the Intake Air Temp is sampled at the MAF, upstream a bit from the actual TB, but regardless, cooler here is a good idea except maybe in really cold climates..

Cool thanks! I'll hit up auto zone here soon then!

Yes, bypassing the pairs of lines at each throttle body would get the coolant out of the TB at least. I figure if you're gonna do it, may as well go all the way and get those extra hoses out of the engine bay completely.

And no, I didn't feel any difference driving, and neither will you. It's a very tiny mod performance-wise, which might occasionally help your intake air temps by a very a small amount.

I understand about getting the rest of the hoses out of the way, I just wanted to keep the line there just in case I would have to bring the car in for anything. The part where it connects behind the motor sound like it would be a pain to try and get the hose back on LOL!

Actually, there's an even better option if you want to keep it simple:

Just disconnect one hose from each TB, the front-most one (leave the other one connected). These are the ones whose other ends connect to points 'C' and 'E' labeled red in the diagrams at the top. Plug the two disconnected rubber hose ends (like, find an appropriately-sized bolt, stick it in the line, and then use a small hose clamp to secure it, such as the ones already there on the line), and then blow the leftover coolant out of the now-disconnected part of the system (blow air into the open metal connection on one TB, and the water will shoot out the open metal connector on the other).
