Vehicle Fitment

Both applications share a 95.40 mm bore. The 4JH1-T is the earlier mechanical/electronic injection variant used in the KB III generation (2002–2004), while the 4JJ1-TC is the later common-rail turbodiesel fitted to KB IV and V models (2004–2013). Title text confirms KB III coverage with both 4JH1-T and 4JH1-TC engine codes, and KB IV/V D-TEQ coverage from 2004–2010.

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 (4JH1-T, 4JH1-TC or 4JJ1-TC) on your vehicle identification plate and confirm your KB generation (III, IV or V).

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.
