How to identify engine size? 2002 Tacoma

Noob question and first post.

I just inherited a 2002 Toyota Tacoma looks like it has an "access" cab,
80k miles, no 4x4, says SR5 on it.

How can I determine which engine size it has with my puny non-mechanically focused mind?

Any help is greatly appreciated!

 

Check the underside of the hood...my 2000 has an "Important Vehicle Information" sticker that calls out my engine size.

 

this is the 2.7 engine:

but you might have the 2,4 in it so as mentioned check the sticker info.

thde 2rz is the 2.4 and the 3rz is the 2.7

 

Hopping in the shower real quick then I'll check that hood. Didn't see any distinguishables on the engine itself. Has a tag with Barcode and numbers but it's pretty hashed.

 

Gonna take a wild guess and say you have the 3RZ-FE (2.7L) engine. What I can recall from memory on my engine, yours looks very similar to it.

 

^^^^^^^^^^^this^^^^^^^^^

 

Not meaning to threadjack or anything, but is there a way to check any engine size? Such as something easier than looking at the casting number?

 

According to the sticker underneath the hood, its a 2.4!

We have a winner!

Thanks everyone for your lightning fast feedback!
Time to replace the fuel/air sensor

 

hope you have baby hands

 

2wd 5-lug = 2.4

2wd/4wd 6-lug = 2.7

 

That's a 2.4. Mine has same motor.

 

Thanks again everyone. I'm getting much more comfortable with the truck now. Changed the A/F sensor and have an O2 ready to go.
