I've prowled on here several times looking for information so I decided to sign up. I have a 1995 F350, crew cab, dually, with an aluminum flatbed. I use it primarily for work but also tow our travel trailer with it on occasion. 278K miles now. Just had a busy couple of days with PowerStroke projects. Just completed the infamous oil dipstick receiver to pan leak and yesterday, I put in a 205 degree thermostat after finally realizing that my old 185 degree one had been stuck open for the past 15 years...:frown: Thanks for the info supplied here. You all save owners, doubtless, hundreds of thousands of dollars all combined.
