Hello, I just have a quick question for anyone who is running a 180 T-stat. I installed the Hughes Plenum plate replacement kit last summer and have had no problems until today. My check engine light came on today, so I scanned it and came up with a code that said the engine fails to reach operating temps. Now we here in Wisconsin have had much colder days this season and I have never had the engine light come on. So I am thinking the new T-stat is stuck open. Have any of you had this problem from running the 180 T-stat in stead of the factory 195? Is this normal engine light with the upgrade?
