Would really like to see detailed pictures in the tubes and everything that need to be plugged also. I have my gasket installed with my UR turbo kit and I thought the manifold was still pretty hot to the touch but didn't think about it still receiving coolant. Can't wait to see the pictures so I can fix this.

I used a little bolt + a short hose and clamped off the coolant return side (at the water pump).

The coolant flow through the IAC for ? reason but the design looks very weird. I don't know whether the stock ECU can sense any of this coolant. However the aem ems control idle via the coolant temp and the sensor is further back in the mainfold (which is unaffected by this modification). There is no problem for me so far with the aem ems and idle.

Here's the pictures.

This is the return hose by the intake. I've got a 5/8" barb plugged into a 5/8" hose.





Here's the other side. Just mates to the bleed nipple. The bleed nipple is next to where the hondata insulator is located, towards the front of the engine.




The line is about 1.5 ft long.


That's it and no more coolant in the TB or intake manifold.

Unless you have a vented hood, the manifold will still get hot especially when the car is shut off.

It's like having a piece of aluminum in the oven. It'll pick up radiated heat. The advantage of having coolant flow through the manifold is that manifold doesn't get as hot as quick since you also have to heat up the coolant (unless coolant is hotter than engine bay temps.)

On the other hand, the coolant also slows down the rate of cooling. The hot manifold will cool off much quicker without hot coolant flowing through the manifold.

In other words, the manifold will still feel hot when parked even without any coolant in the manifold. But when you start to drive, it cools much quicker.

That looks pretty simple and thanks. But do we need to cap the end on the TB and the one where the return line was disconnected?

You can cap them if you want to prevent dirt and dust to get in there. Those lines don't go anywhere now. You can also remove most of the unused hoses.

I did this last week. I just used a rubber nipple with a clamp to cap it off at the ther. housing. Easy fix and got rid of four hoses. I'll post a pic later.

I tried to get a pick of where I capped it off but could not.

Sounds good and thanks for the pics.

- it makes it look like its incomplete.
- plug a hose in the two places, dummy hoes
