LS1 Factory Temp Sensor Needed????

Hey guys almost finished with swapping my ls1 into my nissan 240sx. I was wondering if i need the factory temp sensor if i plan on installing another one for an aftermarket water temp gauge anyway!!!

theres a bolt that plugs the hole where the factory temp sens goes but its stripped. I know i can get a bolt remover kit but that would also mean id have to remove my header because its in the way. basically a huge pain in the *** to do so. I also know theres another hole on the passenger side of the block but that bolt is not wanting to come out and i dont want to strip it. need help!!!!

It's up to you if you want to use the factory one or not. I just got done doing the same thing and I didnt remove the header.

well im using aftermarket headers, and theres not enough room for me to fit a bolt remover without taking the header off. someone told me the pcm needs to be able to read the temp sensor for timing but that makes no sense

Hmm I am unsure about the timing. But I have 1 7/8 headers and was able to get an ez out to it, use and wrench and back it out

Yeah mine are the sikky 1 3/8 headers. i definitely have to take off the header to get the bolt remover on the bolt. Well you didnt have any issues not running it? Car drives fine??

I didn't drive it hard or often with it broke, but it seemed fine
