Yes on VIN.

Also look at gas cap and owners manual.

What yeer and engine.

Post the first 10 of your vin No.

You have a Z engine code.
Does you owners manual have any info on it?
Anything on fuel filler cap?
I do not think the Z engine is flex fuel.
But give your GM dealer a call and have him decode the vin No. for you.
Let us know what you find.

I looked on Auto Zone web site and the show a 02 Tahoe 4X4 Z engine 5.3 is flex fuel.

But be sure to call dealer to double check.

i went to the gm chevy dealer they told me they did not make a flex fuel tahoe in this year they checked the vin and everything so i dunno the cap i got on it is a aftermarket cap i bought myself and dont have the owners manual lol
but on some websites it does ask if this is a flex 5.3l cuz i was goin to get a programmer cuz got 35s on it and body lift ect... so i dont know if i just got a retarded gm parts person when i asked or not lol

prior to 2007 the 8th digit being Z is e85/flex fuel.the tahoe in 2002 was the first year,for the 5.3L.


the guy at the dealership must be out of it..

You're right.

I have the flex fuel option in my '02 Tahoe 4x4 5.3L as well.

the weird thing i got the z digit but i dont have a thing on the vehicle that has ever said anything about flex fuel the first owner was my g/f mom bought it new and she gave it to use about a year ago and not a single sticker or notin on the vehicle saying flex

Alright, try this then: Go to GM's main website and type in the necessary info they ask for INCLUDING your exact VIN and ask your question.

It took them four days to answer me about a van problem I had three years ago.

kk i found my old gas cap on sheer luck just roaming around 1 day the cap all it has on it is wich way it turns and no flex fuel signs or notin

you do have a 5.3Z Flex Fuel Tahoe. all of the gas caps for that year are the same for the 5.3T,6.0U,4.8V,5.3Z,4.3X,8.1G,4.3W,6.0N

L59 is the RPO code for the 5.3L flex fuel engine...look for it on the sticker in the glovebox.
