Need Help Identifying the Correct Cylinder Head?

Toyota produced two different versions of the 1KZ cylinder head, and many engines have been rebuilt or replaced over the past 25+ years.

Do not rely on VIN, model year, engine number, or chassis code alone.

Before ordering, we strongly recommend following our complete identification guide:

Before Installing Your New Cylinder Head

A cracked cylinder head is often the result of another problem—not the cause.

Replacing the cylinder head without addressing the underlying issue greatly increases the likelihood of another failure.

For maximum reliability, HiYota recommends:

• Pressure test injectors
• Inspect injector spray pattern
• Verify injector pop pressure
• Replace worn injector nozzles
• Install a new OEM thermostat
• Flush the complete cooling system
• Replace the timing belt
• Replace the timing belt tensioner and idlers
• Replace the water pump
• Install new head bolts
• Inspect or upgrade the fan clutch
• Inspect the radiator and cooling fan

Faulty injectors and inadequate cooling are among the leading causes of repeated cylinder head failures.

Upgrade Your Cooling System

If your original cylinder head failed due to overheating, we highly recommend upgrading your cooling system during the rebuild.

Our proven HiYota Ultimate Cooling Package includes:

• HiYota Modified Fan Clutch
• HiYota 10-Blade Cooling Fan
• Genuine OEM Thermostat
• EGR Block-Off Kit
• 3” Stainless Steel Turbo-Back Exhaust

Together, these upgrades help reduce coolant temperatures, lower Exhaust Gas Temperatures (EGTs), improve airflow, and significantly reduce thermal stress on the cylinder head.
