Stupid Question about line on a SR20VE...

pimpm3 · 10-28-2006, 07:22 PM

Ok I am hooking up all of the coolant lines and the vacume lines on my SR20VE and I just wanted to verify that this line goes to the underside of my CAI Intake. I would hate to send coolant rushing into my new engine, by my stupid mistake,accidentally hooking up a coolant line to my intake

...

I circled it in Red, it has a yellow cap in the picture and it looks like it runs to the IACC on top of the intake manifold. I am 90% sure that it runs to the intake but I just want to be safe.

Blow some air in it and see where it comes out.

Looks like the line for the intake to me, but its hard to tell from that angle. There are two coolant lines to the throttle body. That line circled looks like the hard line that bolts to the IM. There is a hose on either end, one going into the IM and the other to the intake. Like others said, just follow it, it should be obvious.

Hard to tell in 2d, as I can't tell how far forward it is relative to the hose just to the right of it, which should be the hot water return for the cold idle, but if it's coming off the hard line off the back of the thermostat housing, it's for your heater return hose. You'll find, and you'll see from the install writeups, that it's NOT the same size as the B13 hoses and you'll have to step it down.

100% positive that the yellow capped line goes from the IACV to the intake piping.

Just checked under my hood. Goes to the intake from the IACV.

Yip the yellow hardline with the yellow cap in that pic should have a pipe connecting it to the CAI/intake.

Yah, I spent a few trips out to the car; it does NOT make sense to me esp. with the manifold still on that the tb line is removed and capped, which is why it might be the heater line. It's about the right diameter. How about a shot from a different angle?

It does go to the IACV, I was pretty sure it hooked up to the intake. Thanks for all of the help guys, I had already hooked it up I just wanted to be safe.
