Hello. New to forum. I’ve always had pilots and a 2011 Crv. Looking at your threads I replaced the Evap purge solenoid. Had to bend the heater pipe bracket to get that bottom bolt. Ordered some stubby sockets for future use. Haha. Anyway next to the solenoid I have just a threaded hole. What goes in there. About an inch to the left of the solenoid. Looks yellow but it’s threaded. I didn’t remove anything that was there but in the past have had a starter and compressor put on. Thanks for any info!!
