Or today, four days later. :/ Question: Does anyone have a thermostat housing from a 2.0 off the car that they could measure the ID of for me?
Stopped by Grainger Industrial Supply today after work, with my thermostat for reference. Wound up ordering 2 internal retaining rings ('snap rings'), a 2"(2-1/4" fully open) and a 1-7/8"(2-1/16" fully open), both in stainless steel.
They'll be in Monday, so hopefully I'll be off in time that they're still open so I can run by and figure out which one will be the best fit. They're about $8 a piece, but should last forever. Til then, it does get up to 185-190 now that it's warm out. It was in the 20's yesterday morning, and it stayed at 160. It was 75 on the way home today, and it sat right at 190 all the way home.
