anyone reroute their coolant line so it won't bypass the throttle body? will that make any difference?

ive heard of some running through the coolant hose off the head

What does that mean?

You want to run a line off the throttle body? Or no?

robs99si

no i want to eliminate the coolant line running through the throttle body and just hook it up directly to the block. that way the throttle body should be at a cooler temp when engine is running, since hot radiator fluid won't be running through there.

Wow... I really don't know if that's possible.

I thought the water going through there was supposed to absorb some heat as it passes through, keeping your TB cooler. If you take it out... I'm really not sure what would happen.

I have it done on my f22....what would you like to know?

There is the write-up, although the pictures are down; let me know if you need any help

robs99si

if you noticed a difference and if it's worth doing.

I would leave it on if it's a daily driver and it's cold where you live. If not, bypass it. I don't like the idea of hot water running through my throttle body.

I've taken it off all my cars. Some TB's don't even have the circuit so you don't have to worry about bypassing anything.

My butt dyno says no BUT I don't like the idea of hot coolant running through my intake manifold & TB. I think on a higher output motor there might be some gains. I think overall with it done I notice a little more "pull" on the highway and less bogging of the engine under high heat.

IMO if you have the time (30-45 min) and tools to do it; why not .
