Volvo Turbocharger
New Replacement Turbochargers for Volvo D12 and D13 Truck Engines
Volvo trucks dominate a big slice of North American line-haul, and almost all of them run two engine families: the older D12 in legacy VNL and VHD trucks, and the D13 that powers most Volvo highway tractors built since 2008. We stock brand new replacement turbochargers for both — the HX52 for D12/D12C engines, and Holset VGT units for the D13 platform including the HE400VG-family 3784777 and the HE431VE/HE451VE-family 85116644. Because Volvo and Mack share engine platforms under Volvo Group, many of these turbos also serve Mack MP7 and MP8 engines — same hardware, different badge. Every unit is new-built to OEM-spec dimensions, balanced, and verified against your engine serial number and the part number on your old turbo before it ships. Single units and fleet orders move from US stock to repair shops, fleets and distributors.

Why Volvo Fleets and Shops Source Turbos From Us
A VNL with a dead turbo is a load that is not moving. The D13 VGT system is reliable until soot gets ahead of it, and when it fails, the job has two traps: ordering the wrong variant for the emissions tier, and skipping the actuator question until the truck is already in the bay. Our Volvo program handles both before the part ships.
All New — No Core Deposit, Nothing to Return
Every Volvo turbo we sell is 100% new — new CHRA, wheels and housings. No core deposit, no old unit to crate back, no waiting on credit. The job closes when the truck leaves the bay.
D12 and D13 Coverage From One Shelf
We stock the HX52 for D12 and D12C engines and Holset VGT units for the D13 — covering the bulk of the Volvo highway fleet running today. One supplier, one process, whether the truck is a 2003 VNL or a current one.
Volvo and Mack Cross-Platform Knowledge
Volvo D13 and Mack MP8 are siblings under Volvo Group, and many turbo part numbers serve both. If your shop runs mixed Volvo-Mack fleets, we cross-reference across both brands so you stock one part instead of two. Mack-specific units are on our Mack page.
Matched by ESN and Part Number, Not Guesswork
D13 turbo part numbers change with the emissions tier and engine build date. We confirm every order against the engine serial number and the number on your old turbo's dataplate — the mid-cycle changes never reach your bench.
Priced for Fleet and Distributor Resale
Shops keep margin on the job; distributors hold steady wholesale cost from one piece to a pallet. US inventory keeps lead times short. Details on our wholesale program.
One-Year Warranty With Direct US Support
One-year warranty against material and workmanship defects, handled directly by our US team. Before install we run through the root-cause check — oil supply, charge-air leaks, EGR soot load — so the new unit does not inherit the old one's killer. See our warranty page.
WHY CHOOSE US
Volvo turbo supply built for uptime
We hold the common Volvo turbos in US stock, verify fitment before dispatch, and answer install questions after the sale. Fleets come back because the process repeats cleanly — same part, same price, same support, every order. More about our company and quality process.
FAQ
Use three identifiers: the engine serial number from the dataplate, the build year, and the part number stamped on your current turbo. The D13 ran different VGT configurations across emissions tiers — including the 3784777 (HE400VG family) and the 85116644 (HE431VE/HE451VE family) — and those identifiers pin down the exact unit. Send them to us and we confirm before shipping.
Often yes. The D13 and MP8 are the same base engine under Volvo Group, and many turbo part numbers cross between them — the 3784777 serves Volvo D13 and Mack MP7/MP8 applications. Always verify by part number rather than badge; we cross-reference both catalogs on every order.
D12 and D12C engines run the Holset HX52, a wastegated fixed-geometry turbo. Our HX52 covers the 430 HP D12 family with the full set of Volvo cross-reference numbers, including 3599996 and 20516147.
Depends on the listing — each product page states whether the actuator is included. On D13 VGT units, the electronic actuator must be calibrated to the turbo after installation using Volvo Premium Tech Tool (PTT) or equivalent dealer-level software. If your actuator tests good, it can usually transfer to the new body.
All units are 100% brand new with all-new internals — no rebuilt cores, no core charge, nothing to ship back. Balanced, built to OEM-spec dimensions, one-year warranty.
Yes. Fleets, repair shops and parts distributors are our core customers. Consistent wholesale pricing from single units to pallets, all shipped from US inventory. See the wholesale page for details.
Volvo Truck Turbochargers by Engine
Volvo kept its North American engine lineup tight, which makes turbo identification simpler than on most brands — once you know which engine and emissions tier you have. Here is how the platform breaks down.
D12 and D12C — The Legacy Fleet
The D12 powered VNL and VHD trucks through the mid-2000s and plenty are still working. It runs the Holset HX52 — a wastegated, fixed-geometry turbo with no electronics. Failures at this age are mechanical: bearing wear, shaft play, tired seals, and oil consumption showing up as blue smoke. The fix is straightforward because there is no actuator or calibration step — bolt on the new unit, prime it, run it.
D13 — The Workhorse
The 12.8-liter D13 has powered the majority of Volvo highway tractors since 2008, and every generation runs a Holset VGT with an electronic actuator. The turbo doubles as the engine brake — the vanes close to build backpressure — which is why a weak engine brake is often the first sign of VGT trouble. Part numbers shifted across emissions tiers: the 3784777 (HE400VG family) covers a broad band of D13 and Mack MP7/MP8 builds, while the 85116644 (HE431VE/HE451VE family) serves later D13 and MP8 configurations. The build date and ESN decide which one your engine takes.
Quick Reference: Volvo Engine to Turbo
| Engine | Displacement | Turbo family | Type |
|---|---|---|---|
| D12 / D12C | 12.1L | HX52 | Wastegated |
| D13 (with Mack MP7/MP8) | 12.8L | HE400VG family (3784777) | Electronic VGT |
| D13 / MP8, later builds | 12.8L | HE431VE/HE451VE family (85116644) | Electronic VGT |
Part numbers vary by ESN and emissions tier — send us the engine serial number and the old turbo's dataplate number and we confirm the exact match.
D13 VGT Failure: What Actually Happens
The pattern mirrors every modern VGT diesel. Exhaust soot coats the nozzle ring, the vanes drag, the actuator works harder until it fails, and the driver reports a weak engine brake, slow boost, high EGTs or a derate. Trucks on short-haul or high-idle duty soot up fastest. When replacing, answer two questions first: did the actuator fail, the turbo, or both — and what loaded the system with soot in the first place. An EGR problem or a leaking charge-air boot left in place will take out the new turbo on the same schedule it took the old one.
Install Notes
Prime the turbo with clean oil before first start, replace the feed line if there is any sign of coking, and idle the engine several minutes before load. On VGT units, complete the actuator calibration with PTT and verify the full vane sweep before releasing the truck. Twenty minutes of process protects a four-figure part.
