Browse 1999 Mercedes Engines by Model
Match your 1999 Mercedes engine by vehicle. Mercedes identifies these engines by chassis Type code — 140, 129, 210, 202, 163, 208, 170 — and 1999 is a changeover year on two lines at once, so the Type code matters more than the badge. Use the cards below to identify the right body style; every unit is then VIN-matched at the order step.
1999 S Class
140 Type S320 (3.2L inline-six), S420 (4.2L V8), S500 (5.0L V8) and S600 (6.0L V12) — plus 129 Type SL500 and SL600 cross-cataloged under this badge. 1999 is the FINAL year of the 140 Type S Class; the 220 Type arrives for 2000 and does not interchange. Match the Type code, not the badge.
1999 SL Class
Carries the SAME six units as S Class in our catalog: 129 Type SL500 (5.0L V8) and SL600 (6.0L V12) roadsters, plus 140 Type S320, S420, S500 and S600. The 129 Type runs on through 2002; the 230 Type arrives for 2003. Trust the Type code over the badge.
1999 E Class
210 Type E320 (3.2L V6), E430 (4.3L V8), E55 (5.5L V8) and the E300D turbo (3.0L turbodiesel inline-six) — the only diesel in the 1999 line. The E55 is NEW for 1999. The 211 Type arrives for 2003.
1999 C Class
202 Type C230 (2.3L supercharged four), C280 (2.8L V6) and the C43 AMG (4.3L V8). The 202 Type is the pre-203 body — the 203 Type arrives for 2001 and shares no engine mounts.
1999 CL Class
140 Type CL500 (5.0L V8) and CL600 (6.0L V12). 1999 is the FINAL year of the 140 Type CL coupe; the 215 Type arrives for 2000. Confirm the Type code stamped on the block before ordering.
1999 ML Series
163 Type ML320 (3.2L V6) and ML430 (4.3L V8). The ML430 is NEW for 1999 — 1998 was ML320-only. The ML55 joins the 163 Type line for 2000.
1999 CLK
208 Type CLK320 (3.2L V6) and CLK430 (4.3L V8). The CLK430 is NEW for 1999. The 208 is the only CLK chassis this year — the 209 Coupe joins in 2003.
1999 SLK
170 Type — the SLK230 Kompressor 2.3L supercharged four, the sole US SLK engine for 1999. The 171 Type arrives for 2005 and does not interchange.
Why Buy a 1999 Mercedes Engine from Auto Power Source
Every 1999 Mercedes engine in our inventory is pulled from a low-mileage donor vehicle, cataloged by chassis Type code and VIN, and held in our climate-controlled warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching, compression testing, noise & smoke verification, full visual inspection, multi-angle photography, and palletized shipping.
1999 rewards a careful buyer. It is the last season of the 140 Type S Class and the 140 Type CL coupe, so a 140 Type block is a closing-year part and the 220 and 215 Type successors that follow for 2000 will not bolt in. Our ASE-certified technicians compression-test every cylinder and run a leak-down evaluation before any 1999 Mercedes engine is cleared for sale. You pay a fraction of dealer-new pricing for identical Mercedes engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get up to a 3-year warranty plus 30-day money-back. Not sure which Type code fits? Text your VIN and we will confirm.

Tested used OEM hits the sweet spot — same Mercedes engineering as new, fraction of the cost. On a closing-year 140 Type block, a VIN-matched used unit is often the only sensible option left.
1999 Mercedes Engine Buying Guide
-
Read the chassis Type code first. Mercedes catalogs these engines as 140, 129, 210, 202, 163, 208 and 170 Type. The badge on the trunk lid is not enough — the Type code is the fitment authority.
-
Treat 1999 as a closing year on the 140. Both the S Class and the CL coupe finish their 140 Type run this year. The 220 Type S and 215 Type CL that arrive for 2000 are different engines and will not interchange with a 140 Type block.
-
Do not trust the S / SL badge on its own. In our 1999 catalog the S Class and SL Class listings carry an identical six-unit set — 140 Type S320, S420, S500, S600 plus 129 Type SL500 and SL600. Order on the Type code and the VIN, not the badge.
-
Separate gasoline from the E300D turbodiesel. The 210 Type E Class runs a 3.0L turbodiesel inline-six alongside the 3.2L V6, 4.3L V8 and 5.5L V8 — the diesel shares nothing with the gasoline units.
-
Always run the donor VIN if available. We provide it on request for any engine in our inventory to verify mileage and history.
Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
Frequently Asked Questions
What is the warranty on a 1999 Mercedes engine?
Up to 3 years, depending on the specific unit. The exact warranty term is listed on each product page, and every 1999 Mercedes engine also carries our 30-day money-back guarantee.
What does compression-tested mean?
ASE-certified technicians compression-test every cylinder and run a leak-down evaluation before any 1999 Mercedes engine is cleared for sale. Nothing ships on a visual inspection alone.
How long until delivery?
Prep and ship time is 3-5 business days. Transit time is 2-3 business days via freight carrier after dispatch.
Can I see photos before I buy?
Yes. Multi-angle photos of the actual 1999 Mercedes engine are sent to you before payment, for your approval.
Do I need my VIN?
Strongly recommended. 1999 is a hinge year for Mercedes — the S Class and CL are in their final 140 Type season while the SL runs the 129 Type, and the S/SL badges are cross-cataloged. The VIN resolves the Type code.
What if I do not approve the photos?
Every dollar back — no restocking fees, no return freight charges.
Why is a used OEM engine cheaper than the dealer?
You are buying the identical Mercedes engineering from a low-mileage donor vehicle rather than a new-production unit, so you pay a fraction of dealer-new pricing for the same 1999 Mercedes engine.
When can I reach customer service?
24h Mon-Sat on 1-877-313-8995, or text your VIN any time and a specialist confirms the match.
