One Teardown, One Kit: Head Gasket Set and Timing Chain Kit for the 2010 Toyota Matrix 1.8L

A failed head gasket and a worn timing chain tend to show up in the same chapter of a 1ZZ-FE engine's life. Once the cylinder head comes off, the timing chain is exposed anyway — so ordering the two jobs as separate part purchases just adds shipping delays and mismatch risk. The Head Gasket Set Bolts Timing Chain Kit 2010 Fits Toyota Matrix 1.8L HS54773B solves that by packing the gaskets, head bolts, and complete timing hardware into a single box.

What the HS54773B actually is

This is a comprehensive engine repair package built specifically for the 2010 Toyota Matrix 1.8L. It covers a professional-grade head gasket replacement and a full timing chain service in one purchase, and the components are engineered to meet or exceed OEM specifications. You are not trading quality for convenience here — the kit is aimed at professional mechanics and experienced DIY enthusiasts who want the job done once.

Head off, chain off. One teardown, one parts order, one car back on the road — that is the whole idea behind the HS54773B.

Every Component in the Box

The HS54773B kit includes the following critical components:

• Multiple Layers Steel (MLS) cylinder head gasket — premium sealing performance at the head-to-block joint.
• Intake manifold gasket — keeps the air-fuel mixture sealed where it belongs.
• Exhaust manifold gasket — a leak-free connection on the exhaust side.
• Complete timing chain kit — chain, guides, tensioners, and sprockets.
• Cylinder head bolts — high-strength hardware for proper head clamping force.
• Water pump — the cooling component you want fresh while the engine is open.
• Additional seals and gaskets — comprehensive coverage for the remaining sealing points.

Note the water pump. Replacing it on its own means repeating a big chunk of the labor you are already paying for, so having it included removes a second teardown down the road.

Specifications at a Glance

Cross-check these numbers against your old parts before you order:

The interchange numbers matter in practice. If the gasket set or timing kit you are replacing shows HBTO55 or TK928 on the box, the HS54773B takes its place directly — no cross-referencing headaches at the counter.

Why Buy the Complete Kit Instead of Separate Parts

It costs less

Buying every gasket, bolt, and timing component individually adds up fast. The kit approach is significantly more economical, and it guarantees the parts are matched to each other — the head gasket, bolts, and chain hardware were selected for this engine as a set.

It saves time

One package means no waiting on a backordered tensioner from a second supplier while your Matrix sits on jack stands. On a job where component compatibility and timing are critical, knowing everything arrived together removes a whole category of mistakes.

The parts meet a professional standard

Kit components are manufactured to meet or exceed OEM specifications. The MLS head gasket is the headline upgrade: compared to traditional composite gaskets, multiple layers of steel seal better, handle heat better, and deliver longer service life.

Fitment: Does It Match Your Car?

The kit is designed specifically for the 2010 Toyota Matrix 1.8L with the 1ZZ-FE engine. It may also be compatible with other Toyota vehicles using the same engine platform from 2009–2014, so match your model year and engine code against the table above before ordering. Thirty seconds of checking prevents the most common kind of return.

Working on a different engine? Koeep also carries a Cylinder Head Gasket Bolts Set for the Toyota Camry, RAV4, and Matrix 2.4L, which covers the larger four-cylinder in those models. And if the same Matrix is due for transmission service while the head job is scheduled, a Transmission Filter with Pan Gasket for the Toyota Matrix, RAV4, Scion, and Lexus ES300 consolidates the fluids-and-seals side of the refresh.

If your garage holds a very different project — say a 1995–2000 GMC Yukon K1500 — the same practical approach runs through our front tie rod end, sway bar, and wheel hub bearing guide for the Yukon K1500: part numbers first, then the hands-on details.

Installation Notes Before You Start

• A comprehensive set of metric tools, including torque wrenches.
• Timing chain alignment tools for the 1ZZ-FE.
• Possibly specialized equipment for head resurfacing, depending on the head's condition.
• A service manual for your exact vehicle — highly recommended.

Head gasket and timing chain replacement is complex work. Experienced DIYers with proper tools and solid mechanical knowledge do complete it successfully. If you have never torqued a head in sequence or set a timing chain, hand the kit to a professional — the parts are the easy half of this repair.
