as i understand it, this allows for vacuum to pass to egr when coolant hits 104F...my valve on the austin cargo has been bypassed with a short length of hose since ive owned it..ive also eliminated some of the other vsv's. i live in a moderate temp zone and feel like my coolant hits 104 fairly quicky and havnt had any noticable issues with this bypass...my question is, what negative effects can occur with the egr being activated before coolant hits 104? it has been extra cold here this winter and i do like to take the van into the mountains...
