I recently bought a 2000 F250 7.3 w/ standard trans. I rebuilt the turbo and put in a wicked wheel, replaced the intake tubs and cooler tubes, removed the valve that runs the high idle, put a BAF in it, a cheap chip, performance exhaust, did the fix on the injectors and put new glow plugs in it, etc. This thing will out pull my 2005 5.9 3500 ram dully, but I do have to watch the EGT's.... 210K when I bought it, great truck!! And yes, part of the reason I like this truck, it rides like a truck
Lucky for me this truck wont see many freezing temps with it living in Southern Utah.There is an additive for the coolant to keep the cavitation in check.
Glow plugs are a pain, pain to install and pain to keep all 8 working longer than a week. Block heater is gold when below freezing.
Using an ELC coolant after flushing the block of the old SCA-type means no more additive. And, its good up to 600,000 miles. I've owned a couple of 7.3Ls over the past 15 years (continuously). I've preemptively changed glow plugs at 120,000 miles (not difficult) with motorcraft brand and have never had a failure. The 4r100 in my current truck (02 Superduty) is over 17 years old and has not been rebuilt and is doing just fine (its used to tow the jeep and typically sees GVW at 17K). I have a "6.0" cooler and a John Woods valve body. With a gauge to monitor temps, I have had zero issues.There is an additive for the coolant to keep the cavitation in check.
