99 tahoe

Not necessarily. GM started using the 5.3 in 1999.

In the Yukon's? Or the pickups?

that started in the gmt800 suv platform in 2000. the trucks model year with new engine designs started in 1999 but were actually first sold in 1998.

the a 99 tahoe cant have a 5.3?

 

[SunlitComet]

no it was still a gmt400 platform then for the tahoe. you should have a 5.7l engine.

I recently bought a '99 SLE with 104K, so it reads???
I was surprised that it had the newer spider and FP, although both needed replacement. Cats were shot and the computer was a mess. It now runs great!

I had a 1999 Suburban with a 5.3L. My brother had a 99 Silverado with the same...

so I got the guy down to $3,100. the truck has 98K on it and the interior is basically spotless. Anything else I should be looking for or have my mechanic look for?

Properly functioning a/c front and rear. The right fluids in the right places.

Still not buying this 5.3l vortec in a '99 suv. I would need to see the actual VIN sticker on door to believe it. The suv's were not supposed to get them till 2000.

I know there were a very select few OBS trucks that got 5.3's. We had an extended cab z71 in the shop once when I was in tech school. Our instructor thought it was dropped in until we looked at the vin. Never heard of one in a tahoe though. Besides, I like the 5.7's better anyway. Early 5.3's weren't all that great imo. 03+ when they were drive by wire is when they got good.
