23013334 | Genuine Volvo® / Mack® Piston Cooling Control Valve

Description and Purpose:

Genuine Volvo  / Mack Piston Cooling Control Valve. Part Number:  23013334. Condition:  New. This is a 12 V solenoid‑actuated valve that meters oil to the underside of each piston in D11, D13 diesel engines. By opening only when oil pressure and temperature demand it, the valve creates a targeted cooling jet that limits crown and ring‑land heat, keeps the oil film stable, and reduces carbon build‑up. Its calibrated orifice and fast response help the engine hold consistent combustion temperatures during long uphill pulls or sustained highway speeds.

Why Replacement is Important:

Sludge, varnish, or spring fatigue can cause the valve to stick, starving pistons of cooling oil. Timely replacement prevents local hot spots, ring scuffing, and piston crown cracking, averting costly in‑frame repairs.

Impact on Vehicle Performance:

Reliable piston cooling maintains uniform cylinder temperatures, which supports steady power, lower oil oxidation, and improved fuel economy—especially noticeable on heavy loads and extended service intervals.
