newb question on thermostat/housing Are there different styles of thermostats for LS cars? The reason I ask is because when the thermostat/housing was removed from my LS1, it didn't come out as one piece, it came out in two...
I was under the impression that the thermostat/housing was all one piece. I found this pic and now I'm confused.
Went and got a thermostat for a 98 Camaro Z28 from OReillys and it does NOT fit my water pump housing.
Thanks for any help/advice.

You must have a newer water pump on your car with the different style 2 piece thermostat and housing. (They're shown in the bottom left corner of the picture you posted.)
Just return the one you purchased from O-Reilly's and find one from Scoggin Dickey that will fit your application. Thats what I did, when I ran into the same problem with the SLP unit I attempted to install. Here is a link to what you need.

Old thread but this is relevant to my question. I have a 2000 trans am with the older style water pump. Can I swap the one piece thermostat/housing for the newer style one with the separate housing and thermostat? This would make flushing the coolant a lot easier if I could just remove the thermostat and install the housing without it.

Iam not positive but I think the bolt pattern at the housing is different. Easiest way to check would be go to the parts store ask for both parts and compare. If I am wrong some one chime in and let me know.

It looks like the newer style should bolt to the older style pump. The older housing has that extra hole, which is just to hold a plastic wire clamp IIRC, which you don't really need. I'm going to replace mine with a new style one the next time I change the fluid, then changing the thermostat will be much easier/cheaper.

I test fitted a newer style t-sat (2 peice) with the original LS1 style pump, it will not fit right, the end of the t-stat hits the inner rim of the water pump. So you need to match the t-stat with the right pump. Pep boys sells the LS1 style pump which is a Bosch one. And also do not get a new o -ring gasket from advance auto, its to small.
