If you have a diesel supplement owners manual for 1990 F350 7.3 IDI can you please tell me the amount and type of oil and atf required? Also would like to know the capactity for coolant if it's in there. Thanks.
Why not use mercon v, looks like trackspeeder said it was fine?Coolant capacity is ~8 gallons....
Which Transmission? C-6 or E4OD (3 speed or 4 speed Overdrive)
If it's a C-6, 12 quarts if completely empty. Looks like you can use Type F or Dextron/Mercon - DO NOT use Mercon V - From this thread: http://www.oilburners.net/forums/showthread.php?24928-C6-Trasmission-Fluid-Capacity
If it's an E4OD, 16.2 quarts (if 4x4 E4OD), 2wd uses less. Dextron/Mercon - DO NOT use Mercon V - From this thread: http://www.oilburners.net/forums/showthread.php?40959-Fluid-change-volumes-recommendations-please
Glad you posted that because the Ford dealer told me to use Mercon V. That might be whats in there now. Just bought the truck. I think the trans is 4 speed with overdrive, I'll figure it out. Thanks
