Engine Options
Which engine does your Tahoe have?
The Tahoe is the short-wheelbase member of GM’s full-size SUV family. The first one, the 1995–1999 GMT400, ran a 5.7L V8 — the throttle-body L05 for 1995, the Vortec L31 from 1996 — with a 6.5L turbodiesel on two-door 4WD models, and the 5.7L carried on in the 2000 Limited and Z71. Since then its engines have followed the Silverado’s: Gen III Vortec 4.8L and 5.3L V8s from 2000, Gen IV 4.8L and 5.3L V8s from 2007 (plus a 6.2L on the 2008–2009 LTZ and a 6.0L in the Hybrid), the direct-injection EcoTec3 5.3L from 2015 with a 6.2L on the RST from 2018, and since 2021 the 5.3L, the 6.2L and a 3.0L Duramax diesel.
The table below lists what was offered when. One 5.3L badge covers iron-block, aluminum-block, gasoline and flex-fuel engines, and a 1995 5.7L is a different engine from a 1996 one, so we confirm the engine code from your VIN before we quote.

Before You Order
What to check before you order
1995 or 1996–1999
The 1995 Tahoe’s 5.7L is the throttle-body L05. From 1996 it is the Vortec L31, with different cylinder heads, intake and injection and an OBD-II computer. The two share a displacement, not a part number, so the model year tells us which to quote.
Which 5.3L
Tahoe 5.3L V8s include the LM7, L59, LY5, LMG, L83 and L84. They differ in block metal, fuel system, injection and cylinder deactivation, so we match the RPO code, not the displacement.
Two- or four-wheel drive
Drive type decided the engine in some years: the 1995–1999 diesel came only on two-door 4WD models, the 4.8L was not offered on 4WD after 2005, and the 2007–2009 LY2 4.8L was 2WD only. Tell us which you have.
Hybrid or not
The 2008–2013 Tahoe Hybrid pairs its 6.0L with the Two-Mode transmission and a 300 V battery. Its engine is not interchangeable with a 5.3L Tahoe’s, so tell us if yours is a Hybrid.
Cylinder deactivation
Every 5.3L Tahoe from 2007 has Active Fuel Management (the 4.8L does not), and every 2021-on V8 has Dynamic Fuel Management. The replacement has to match what the Tahoe’s computer expects.
Have your VIN ready
With the VIN we can confirm the engine code, model year and drive type before we quote, which avoids ordering the wrong version.
Common Problems
Common Tahoe engine problems
Intake gaskets and injector spider — Vortec 5.7L, 1996–2000
The L31’s lower intake-manifold gaskets leak coolant with age, sometimes onto the ground and sometimes into the oil, where it destroys the bearings if the engine is kept running. The central injector assembly, or spider, also sticks and leaks, bringing misfires and hard starts when hot. Both are repairs if caught early; an L31 that has run on coolant-thinned oil is the one that needs replacing.
Cracked block and heads — 6.5L turbodiesel, 1995–1999
The 6.5L is known for cracking the main-bearing webs of its block, which ends the engine, and for cracked cylinder heads, usually after overheating. A Tahoe diesel that stalls or will not restart hot usually has a failed pump-mounted driver (PMD) on the injection pump rather than an engine fault, so rule that out first.
Cracked cylinder heads — early 4.8L and 5.3L
Some early Gen III cylinder heads, cast by Castech with casting number 706, are porous and can crack, so coolant disappears or ends up in the oil. Early Gen III engines are also known for piston slap, a knock when the engine is cold.
AFM lifter failure — 5.3L, 2007–2020
A lifter on a deactivating cylinder sticks, the engine misfires and drops into limp mode, and if it is driven on the camshaft lobe is wiped. The repair means lifters, guides, camshaft and the valve-lifter oil manifold with the heads off, which is why many owners replace the engine instead.
Rod-bearing failure — 6.2L L87, 2021–2024
GM recalled 2021–2024 Tahoes with the 6.2L L87 because manufacturing defects in the crankshaft and connecting rods can destroy the rod bearings and seize the engine. Dealers inspect the engine and repair or replace it if it fails; one that passes is switched to 0W-40 oil. Check by VIN whether the recall has been done before paying for a replacement.

FAQ
Tahoe engine questions, answered
Did the Tahoe ever come with a 6.0L?
Only the 2008–2013 Tahoe Hybrid. Every other Tahoe has had a 5.7L (1995–2000), 4.8L, 5.3L or 6.2L V8, or a diesel: the 6.5L turbo on 1995–1999 two-door 4WD models or the 3.0L Duramax from 2021.
Will an engine from a Silverado, Suburban or Yukon fit my Tahoe?
Usually. Tahoe engines are shared with the Suburban, the Yukon and GM’s half-ton pickups of the same generation, so an engine with the same RPO code is normally the same unit. Send us your VIN and we will confirm the match.
What should I know about the 3.0L Duramax?
Its oil-pump belt sits at the back of the engine and is due for replacement at 150,000 miles on the LM2, and the transmission has to come out to change it. The 2021–2024 Tahoe has the LM2 and the 2025-on Tahoe the second-generation LZ0, so tell us your model year.
Is the engine covered by a warranty?
Yes. Every engine we sell is covered by warranty, and extended cover is available at extra cost. The full terms are in our Warranty Policy.
