I'd wonder just how cold "cold" really is, compared to the pretty invariable "operating temperature", are you gonna set it cold in Jan or July? .... I believe there is a spec for cold setting in the shop manual, but they point out that it's important that all the metal as well as the oil should be operating temp for accurate setting to the hot specs
