78zman Posted November 29, 2016 Share Posted November 29, 2016 Can someone please tell me what system this part belongs to? (Fuel, Coolant, Vacuum) and where it's supposed to be located? Thanks Quote Link to comment Share on other sites More sharing options...
AkRev Posted November 29, 2016 Share Posted November 29, 2016 That is a coolant block that sits under the air regulator, I do not know the proper name, but the job of the part is to warm up the air regulator on hot starts very quickly so you do not have high idle on hot starts.

Tony D Posted December 24, 2016 Share Posted December 24, 2016 And the vacuum lines are switched by temperature to enable the EGR once above 170F Quote Link to comment Share on other sites More sharing options...
