Direction Of Waterflow Through Throttle Body

[boostn0199]

Does anyone know the direction the water flows through the throttle body on rb25 is it from left (front of engine) to right (rear of engine).

Id say from right to left (usually front of the engine is water returning to the rad.

Are you trying to tee into the return?

It hardly matters.

It hardly matters.

Exactly what I was thinking.

Why do you want to know Boostin0199, got some crazy plan?

[hardsteppa]

Lol...hardly matters to most ppl but obviously does to OP, cause he asked. 99% sure its from rear of engine to front, with front hose leading to air bleeder screw.

Imm going bypass it going to the throttle and instead use it for my turbo water lines as i cant be bothered unpluging and use the line at the rear of the head lol.

So for turbo syphoning purposes i wana know which side coolant feeds from.

[gotRICE?]

Im under the impression its from rear to front too. Based on the turbo water return.

The turbo water feed is straight off the block FYI.

Pretty much what I thought, it doesnt matter at all which way it flows through the throttle body but figured he wanted to plumb something in as a water return

If you are purely asking so you can hook the throttle body coolant lines up, I wouldnt even bother. I havent had coolant lines to mine for about 4 years with no problems at all

[boostn0199]

Yeah I was thinking logically it should be from back to front since the water goes to the air bleeder.

No sub-zero temps around Mackay either Callan. Might make a difference for someone running a daily driver in the Southern climes.

The easy way to find out is to disconnect both hoses, aim both at a bucket, crank engine over and see which one squirts.

/thinking about it.

[boostn0199]

Well thats the last option lol.

Not many places in aus are going to get cold enough to need it. Obviously I wasnt suggesting it was ok in all cases but usually once the cars warm there is never going to be sub zero temps around the throttle body In aus
