Replacing heat sensor right now and found no water anywhere in oil....but I think my son got wrong weight for oil from Jiffy Lube. i am going to see what changes if anything with new sensor before I remove Thermostat. if it continues to heat up I will take to my cousin at Pep Boys and have them test everything. I can only work on sporadically due to service calls and panel builds. Evenings are spent feeding and spending time with RJ in hospital. He is gaining weight slowly and hope to have him out this week. thanks for all the tips...soon I can start my own talk show on NPR....El Guy Mechanico Chafa
