i switched over to a LT1 radiator and i know about the temp sensor you plug on the driver side at the bottom, but what is this plug?


please let me know guys cause this is the only thing thats stopping me from firing up my car for the first time in 6 months lol

 

That open hole is for the coolant level sensor, it has 2 small o-rings on it.

 

oh **** i wonder if i left it on the old radiator when i pulled it

 

so since that sensor is a bs sensor can i just use something to cap it off?

 

Some plug it with JB Weld or just get a old sending unit to fill it. If you car is a 99-02 you won't have one on the old radiator.


I'll be finding a old sending unit when I put my LT1 radiator in

 

Since I'm planning on doing the LT1 radiator, just wondering if yours fit OK and how much of a PITA it was to install.

 

Dumb question - what's the advantage of putting an LT1 radiator in an LS1 vehicle?

 

It's a little bigger (holds more coolant).

 

The LT1 is a little thicker than the LS1, 1 1/4" vs. 15/16"

There is a picture of the two in the thread below

LT1 rad ftw..I'm using one with my car.

 

Cool, learn something new every day.

 

Its just the useless coolant temp sensor hole. I went with the LT1 radiator when my stock LS1 developed a crack on one of the side holding tanks last December. My LS1 sensor fit just fine. If you cant find a replacement, let me know, I've got an extra one laying around. Non-working but functional as a plug.

 

bought the sensor and filled the hole
