Thermostat installation question
I've looked over some of the threads regarding the changing of the coolant thermostat but, not seeing one aspect:
Is there a permanent or replaceable gasket between the engine block and the thermostat housing? I purchased my 170 thermostat from Summit but, it came without a gasket. Do I need to purchase one? Sources?

Be careful, if the summit stat is like or is the lingenfelter stat, you will have issues with the outer seal splitting and start having slow warm ups in a 1000 miles. There is a great post with pics regarding this problem on this C7 tech section. I have it saved in my favorites and do not know how to attach it here. Compare the pics of the lingenfelter stat to summit's.

I just got a refund on my Lingenfelter unit, they have not come up with a revised unit yet. I hope the Summit unit is a totally different design. Compare the OE seal and thermostat unit, the seal is built in. If the summit unit looks like the Lingenfelter unit, I would monitor your warmups after a good 1000 miles. You have to wonder how many manufacturers other than 1 actually made this particular style stat.

It is definitely different. I have had both. Summit is currently installed and works great. Using the 170 deg T-stat with stock tune has not given me any codes. Been in for a couple months now. I had both 160 and 170 from Lingenfelder and both failed, even though I got the burr off the stock spring. The seal gets loose and pinches when closing. Eventually the gasket rips.
