Vehicle Fitment

All applications share the Isuzu 4JK1-TC/4JK1-C 2.5-litre common-rail turbodiesel engine with 95.40 mm bore. The four KB250 feed entries reflect 4x2/4x4 drivetrain and model-year generation splits (KB IV 20072013 and KB V 20152018). The D-Max I (TFR86J chassis) is the international-market equivalent of the KB platform. Seven OEM reference numbers reflect specification revisions across production years.

Installation Tips

• Clean all mating surfaces thoroughly, removing old gasket material and carbon deposits before fitting new gaskets.
• Check the cylinder head and block for warpage using a straight edge and feeler gauge; resurface if out of specification.
• Torque all fasteners to the vehicle manufacturer's specifications using a calibrated torque wrench and the correct tightening sequence.
• Replace head bolts if the engine uses torque-to-yield (TTY) fasteners these are designed for single use only.
• Allow silicone sealant (where specified) to cure fully before filling coolant or starting the engine.

Frequently Asked Questions

What is included in a Full Gasket Set?

A Full Gasket Set typically includes the head gasket, valve-cover gasket, intake and exhaust manifold gaskets, water-pump gasket, oil-pan gasket, and various seals and O-rings required for a complete engine reseal.

How do I confirm this set fits my vehicle?

Match one of the seven OEM reference numbers (e.g. 5-87816038-0) against your vehicle's service manual or existing part. Also verify the engine code (4JK1-TC or 4JK1-C) on your vehicle identification plate.

Can I install this myself?

While mechanically experienced individuals can perform the work, we strongly recommend professional installation by a qualified workshop to ensure correct torque settings and gasket alignment.
