I have a 2000 model (built 04,2000), I bought the thermostat with the integrated housing. I'm not sure which one is on my car. If it ends up being the thermostat without the housing attached can I still use the one i bought? Thanks

If yours is stock it has the integrated housing

I dont think the housings are interchangeable. I Have a 02, ls1 and I had to order the two piece style thermostat.
