What You're Actually Buying
This is the electronically controlled variable speed pump, not the old fixed-speed unit. The ECM tells this thing how fast to spin based on coolant temp, so it's not just swapping a shaft and bearing assembly - there's a control side to it with a connector that has to match your harness.
Volvo D13 and D11 engines from the newer emissions-spec builds use this, and Mack shares the platform on MP7 and MP8, so the pump housing, impeller, and drive are common hardware across both nameplates even though the part numbers look different on paper.
Because it's variable speed, this pump only bolts up right on the engines that were built for it. Earlier D13/MP8 engines ran a straight mechanical pump - don't cross this into that application, it won't control right even if it physically fits.
Why These Numbers Cross
24152057 and 85151955 are the same pump under Volvo and Mack part numbering - Volvo Group owns both brands and shares cooling system components across the platforms, which is why you'll see this piece under either number depending on which parts book you're pulling from.
23959591, 22183231, 22552995 and 7422552995 show up as superseded or regional numbers for the same casting - Volvo updates part numbers over the years as they revise the impeller or seal package slightly, but the mounting pattern and control connector stay the same. 801158E is the aftermarket cross for the same pump.
Watch the electrical connector pins and the pulley/drive spline count - that's where a variable speed pump can look identical to a fixed-speed one but won't talk to your ECM right. Pull the old pump and check the number stamped on the housing or cast into the body before you order, don't just go off engine year.
Ordering From Us
We keep 24152057 in stock at the Tacoma counter - if you're local, same-day pickup is normal, no waiting on a truck from out of state. If you're not local we ship nationwide, most orders out the same or next business day.
This is an aftermarket pump, 6+ month warranty on it. It's built to interchange with the OE numbers listed, not a Volvo or Mack branded part - we don't claim it's original-equipment, we claim it fits right when it's the right application.
Confirm by VIN or by the number stamped on your old pump before you buy. Water pumps on these variable speed setups aren't universal across model years even within the same engine family - a five-minute check on the old part number saves you a return shipment.
24152057 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 24152057. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 24152057 fit my D13 Volvo?
Depends on the year and whether your engine has the variable speed pump setup to begin with. Give us the VIN or pull the number off your old pump - if it's got the electrical connector on it for ECM control, you're probably in the right family, but confirm before ordering.
Is this the same as the Mack 85151955 pump?
Yes, same pump, different part number because Volvo and Mack catalog it under their own systems. It's the shared MP7/MP8/D13/D11 variable speed cooling architecture - one casting, two brand numbers.
Can I use this on an older Mack MP8 that's not variable speed?
No, don't force it. If your MP8 ran the fixed-speed mechanical pump from the factory, this variable speed unit needs the control wiring and ECM logic to work right - it's not a drop-in for the older mechanical setup even if the mounting looks close.
