The Mocal oil cooler adapter is for GM LS-series engines to incorporate athermostat that automatically regulates oil flow toconnected cooling devices. Installation is simple: units simply bolt on in place of the factory gauge sender.

Note: Will not clear many long tube headers. Works with most mid-length, shorty and stock headers.

Features and Benefits
  • -10AN fittings
  • Provision for factory M12 x 1.5 sender.
  • Built-in thermostat bypasses oil until 178° F and is fully open at 185° F.
  • Eliminates the need for an external thermostat, oil filter relocation adapter, and associated additional lines and fittings.
  • Oil is bypassed directly at the block instead of flowing through the oil cooler lines first. This means your engine receives oil quicker during start-up.
  • Includes spacer required for some oil pans
  • Direction of flow: Lower port is the return from the oil cooler.
  • Dimensions: Approx 3.63" (w) x 2.75" (h) x 1.50" (d) (main block), 4.50" x 4.50" x 1.50" (including fittings). Spacer adds 7/16" to depth.
  • 1997 to present LS Series engines (Gen III/IV) including LS1/LS6, LS2, LS3, LS7, L76/L92/L93, LQ4/LQ9, C5R and LSX
  • Will not clear accessories (alternator or power steering) on most front-sump vehicles (GTO, Monaro, Commodore, etc). For these vehicles, use our GTO Oil Cooler Adapter.
