Is there some sort of 3.0L V6 identification guide? My son's 96 Ranger had an engine replaced but I wasn't able to find out what the donor engine was from. Would the engine serial number have that encoded? Where do I find the serial number? If I post a few pics of the engine, can you guys maybe narrow it down? I need an idler pulley for it but I can't just ask for an idler pulley for a 96 Ranger anymore.
Well, the VIN of the truck doesn't mean much when the engine has been replaced. The problem is I don't know which 3.0L V6 is in it now. Aerostar, Probe, Ranger, Taurus, Tempo, Mazda B3000, Mercury Sable, Topaz... I don't know. Nor do I know what year the engine came from.
FWIW, there is supposed to be a "Ford Broadcast Code" sticker that is used by engine rebuilders to determine the exact engine and application ID. It is a paper sticker usually located on the cam/rocker/valve cover and/or the front cover. The stickers are often marred up real good or gone completely, but it's worth a look.
If you get the code you might be able to call a dealer or rebuild shop and have them tell you what application the code points to.
