I have been searching this forum as well as others, but still need some assistance. I purchased the stuff and plan to flush my coolant this weekend, but today my truck started pouring white smoke. I understand that this could be the EGR, blown head gasket, or simply the valve being stuck. I also understand that I can check the EGR by pulling the valve and seeing if it is wet, but how do I determine if it is the head gasket (look at the coolant in the degas tank for fuel/gunk?)? When I get home from work, I will fire up the truck again and see if it is still pouring white smoke. My guess is that if the answer is no, then the valve was simply stuck and I will carry on the flush as normal....
Additionally, how do I check the status of my oil cooler?
My truck is under a 2 year/24k warranty right now (I have to pay $100 deductable) and would rather they correct the issues prior to me flushing my coolant and installing the DFuser coolant filter that I purchased.
Edit: I just purchased and installed the Edge Insight CTS and my temps would hover with a delta of 8 degrees on some trips around town, and 15 degrees on other trips. Occasionally over the weekend, it would spike to a delta of 20, but neither temp was ever over 194. I have not gone on the highway yet to monitor the temps, this was all at about 45 mph with red lights.
