Good evening to all. Im now the owner of a 97 350 cc 4x4. Im not new to diesels but I am new to this engine. 239,450 miles is alot but the rest of the truck is awesome. I new the po and he was very good on maintenance. Any help would be welcomed. Is there anything I should be aware of? I know the truck is up for service and I've never changed this fuel filter is it a mess? Working on equipment is second nature for me so im not afraid it to get dirty. Any suggestions on oil,filters or anything don't hesitate to chime in. Thanks.
