Volvo techs... can anyone tell me while the truck is idling (say while the driver is sleeping) does the egr valve stay open or stay closed or does it go back and forth as needed? Thanks
it opens when coolant goes to 156F and then it cycles on and of as required by ecm opens and closes certain percentage to allow a certain amount of flow this changes a bit between d12 and d13 being that d12 has 2 egrs with position sensors and egr temp sensor and d13 only one with no position sensor it measures only flow of valve via delta p sensor and venturi tube. Hope this helps let me know if you need anything else
VOLVO TECHS can you tell me if a 12k axle and 22ft box would work for expediting on a 2012 vnm 630 converting to straight truck soon. If not can I find a 13,500 k axle and swap over if needed, how much for labor? The 630 has a light cab and sleeper. Also can you tell me what problems to be aware of on D11 with 400-500k miles? Thanks in advance!
