ok... So I'm swapping an LS1 into my 95 240sx. one thing that has bothered me with my LS1 swap is that my S14 has an external valve going to the heater core. It's got this ugly-a** cable coming out of the fire wall and going to a little valve on one of the heater hoses in the enigne bay... not only is it unsightly but it makes this more difficult when dealing with clearances and what not.

here's an old pic... the valve is on the left the cables comes out of the firewall on the right

Come to find out it's ONLY the 1995s that are like this... AFAIK none of the S13s or 96-98s have this external valve.

Thanks Nissan!

My first question is... do the other S14 model years even have this valve at all? I've looked at some ebay listings for heater cores and didn't see anything on them that looked like a valve, though it could just be out of site

If they do have one I'm wondering if I can swap out the valve from a 96-98 and make it internal to give me some more room and clean up the bay a little. or maybe swap out the whole heater core...

Also how hard is it get at the heater core? I already have the blower and AC evaporator removed... will I have to remove the whole friggin dash to get at the heater core? I would hoping I could avoid taking out my dash if I could... :-/

any pictures/advice/etc would be appreciated.

that's a picture from his S13... the valve is in the water neck... I'd be willing to bet I can just swap that out.

I'm posting this just in case anyone else comes across this issue.
