I picked up a thermostat at pepboys yesterday, and after I take the old one out today I find out the new one doesn't fit. I called pepboys, and they confirmed I have the right part number.
The new one looks just like the one that SLP lists, but the lips on the housing that stick out and hold the actual thermostat to the housing are too wide to fit into the hole in my block.

Any ideas? Thanks.
