Six-Star® Head gaskets are a multi-layer stainless steel head gasket engineered to insure years of longevity for your Subaru.
We believe so strongly in these gaskets that we exclusively use Six-Star® brand head gaskets on all of the phase1 and phase2 2.5 liter engines we repair at Smart Service.
We all know that a head gasket issue can be one of the biggest headaches you’ll ever run into on your Subaru. We only use Six-Star® gaskets at Smart Service when we perform a head gasket repair because we want it to be the final time you ever have to replace your head gaskets.
In our opinion, they are currently the best gasket available for the repair.

These are the bare essentials that will be needed to perform a head gasket repair, while the other items included in our full kit are recommended (rear seals, cam seals, crank seal etc) they are not required to replace head gaskets, and if you are attempting to perform the repairs in-car you will not need some items in our full kit. We can always build a custom kit for you with any add-ons desired. This will keep your budget to a minimum while still ensuring the best head gaskets are fitted onto your car, avoiding future headaches with inferior gaskets.

Water Pump and Timing Belt Components
Also available are components for the timing belt and water pump, while these may not be required for your repair, they are always good items to do as preventative maintenance and are much easier to access with the engine work being done.
| Timing Belt | $85.00 | ![]() |
| Water Pump | $80.00 | ![]() |
| Tensioner and Idlers | $249.95 | ![]() |
| Thermostat Kit | $25.00 | ![]() |
Rear Seperator Plate Kit
Also available are the necessary items to replace your rear seperator plate. Many Phase 1 engines came with a plastic plate at the rear of the engine from the factory, and over time the plastic will warp and leak. If you have this engine, and are unsure which yours is equipped with, we highly recommend this kit with the upgraded aluminum plate. Transmission removal is required if doing this by itself instead of with head gasket replacement.

Tune Up Package
Why not invest a little more into your car and bring the other service items up to speed when doing a large repair? See below for our different levels but rest assured all are quality parts, some are Genuine and others OEM, and replacing items like the spark plugs is always easier when performing engine work. We unfortunately cannot sell and ship items like coolant due to hazardous materials restrictions; if local we are glad to sell Genuine Subaru coolant over the counter.
