I recently purchased a '99 f-150 with the 4.2L v6 and was going to change the oil, but don't have a socket or wrench to fit. I'm guessing it's a metric 15mm. Is this correct?

 

It's 15mm or 16mm. What you need to do is go out and buy a simple metric tool kit that has:

-Socket wrench
-Extension
-Spark plug socket
-10mm-18mm sockets

It shouldn't cost more that $40.00 and will last forever if you don't lose anything. As men, we have a responsibilty to buy tools. We have to keep on buying more and more tools until we die and leave them to our children in our will.

Also: When you change the oil, you should be able to remove the filter with gloved hands if you don't have a filter wrench. You should also pre-fill the oil filter with about 1/2 qt before you put it on the engine. Only use quality filters like Motorcraft. No FRAM filters

 

What are wrong with fram filters? I have used them for 90 K and had no problems. Is there something I should know?

Thanks.

 

My 2001 F150 has a 13 mm drain plug...go figure

Also, there have been many threads regarding Fram filters...they are sure junk. Purolator, Mobil 1, Wix are all good.....NOT Fram!!

 

It's a 15mm on mine.

 

Thanks guys. Out of probably 50 or 60 sockets and wrenches that I have, of course the 15mm is the one I don't have. I bought one today and it fits.
