Apex AHG857 Cylinder Head Gasket

The Apex AHG857 engine cylinder head gasket is a direct-fit sealing component for select Toyota applications. It is built for 1995-1998 Toyota Tercel and 1996-1998 Toyota Paseo coverage, including 1995 Toyota Paseo California-only applications.

Key Features

• Engine cylinder head gasket for the sealing system
• Fits 1996-1998 Toyota Paseo, N/A
• Fits 1995-1998 Toyota Tercel, N/A
• Fits 1995 Toyota Paseo, N/A, Calif. Only
• Part number AHG857 for catalog and service reference

Detailed Description

Use the Apex AHG857 when replacing a cylinder head gasket on supported Toyota engines. This gasket helps maintain the seal between the cylinder head and engine block, which is critical for compression retention and separation of combustion, coolant, and oil passages. It is a practical choice for Toyota Paseo and Toyota Tercel engine service where the original sealing surface has been removed and reassembly requires a new head gasket. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Compression loss from a failed head gasket seal
• Coolant leakage into the combustion chamber
• Oil and coolant mixing at the cylinder head interface
• Overheating caused by sealing failure
• White exhaust smoke related to internal coolant intrusion

Installation Notes and Tips

Inspect the cylinder head and engine block mating surfaces before installation. Clean all sealing surfaces thoroughly, verify flatness, and follow the vehicle service manual for torque sequence and torque-angle procedures. Replace the gasket during proper engine teardown and reassembly on the applicable Toyota Paseo or Toyota Tercel engine.

Quality Assurance

Apex identifies this part as an engine sealing component under part number AHG857 for the listed Toyota fitments. Confirm engine code and California-only application details before ordering.
