Forgive me but I dont know alot about cars, I bought a 1992 f150 used without a manual. How do I Know what size the engine is by looking at it?
Any help will be appreciated.

 

Does it have 6 cylinders or 8? If it has 6, it will be a 300 cubic-inch 4.9 liter I-6. If it has 8, it is either a 302 cubic-inch 5.0 liter V-8, or a 351 cubic-inch 5.8 liter V-8.

 

I think it has 6. is there any way of knowing for sure buy looking at it?

 

Just look under the hood. The 6 cylinder is an inline 6. If the exhaust is still from the factory, the 5.8 will have daul exhaust tips out the side. It you have the V8s just look at the top of the intake, it will say either 5.0 or 5.8

 

This Website has a lot of Car specifications. Such as Engine sizes, Etc.

Intellichoice

Just go to the Used Car Search, Find yours. Click on the Specifications tab once you get there. And it should have everything you need to know.

 

Welcome Eaglejake05! The 300 (4.9L) inline six is long and in a line. It will have six sparkplug wires, and six intake "tubes" on top of the engine.

The 302 (5.0L) V8 looks like this...



Hard to tell in that pic of my 92, but there are 8 "tubes" coming out of the large block that says 5.0

Those are the two choices of engines if you have a manual tranny (the M5OD) or the auto tranny AOD (PRN(D)D1) and no overdrive lockout switch on the shifter.

If it is an E4OD auto tranny (PRN(D)21) and has an overdrive lockout switch on the shifter, it could be the above two engines or the 351 (5.8L). It looks the same as the 302, but says 5.8 instead.

Happy posting,
