Need help with intake manifold coolant line - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I deleted the cluster of vacuum lines and I ended up with two lines that are coolant lines that are on the lower intake manifold on the bottom side towards the rear. Just wondering if I really need these or can I just cap them and call it a day. Thanks
I'll try to upload a picture later tonight

They cool your throttle body, I would recommend keeping them. Any reason you want rid of them?

If I'm not mistaken there actually used to warm up the throttle body on cold starts for emmission purposes..I removed them on my sr20.

I was actually completely dumbfounded like, two days ago trying to find a coolant leak turns out it was the coolant line under the IM close to the heater core outlets. Dear god that was a lot of coolant leaking out for such a tiny line..

Unless they are used to control idle like on the q45 throttle body, you can cap them off without any problems.
