Cylinder Head Gasket AJU10157900

Restore engine integrity and prevent head-block leaks with the genuine cylinder head gasket (part AJU10157900). This precision-engineered multi-layer steel (MLS) gasket seals combustion chambers, coolant passages and oil galleries, ensuring optimal compression and reliable thermal management.

Key Benefits

• Exact OEM Specification
  Manufactured to Chrysler’s original CAD dimensions and material specs for a perfect drop-in replacement—no grinding or modification required.

• Multi-Layer Steel Construction
  Stainless steel layers with elastomeric coatings provide exceptional sealing under high pressure and temperature cycles.

• Leak-Free Performance
  Precision-pressed bore openings and fire-rings create uniform compression sealing across all cylinders, preventing blow-by and fluid crossover.

• Thermal Stability
  High-temperature materials resist hot-spot warping and maintain seal integrity through repeated heat cycles.

• Durable Longevity
  Designed to withstand engine torque, vibration and thermal expansion for extended service life.

Installation Overview

1. Prepare Surfaces: Remove old gasket material, clean head and block mating faces, and inspect for flatness.

2. Position Gasket: Lay the new gasket on the block with alignment dowels in place, ensuring correct orientation of coolant and oil holes.

3. Install Head: Carefully lower the cylinder head onto the gasket, avoiding any lateral movement.

4. Torque Sequence: Tighten head bolts in the factory-specified sequence and stages, using a calibrated torque wrench.

5. Reassemble & Test: Reinstall all components, refill coolant and oil, then run the engine to check for proper compression and absence of leaks.
