2003-2009 Toyota 4Runner Internal Engine Parts

A fourth-gen 4Runner engine rebuild, a high-mileage short block that needs a second life, or a performance build looking to tighten up the rotating assembly all require the right internal parts to do the job correctly — and pistons, bearings, rings, timing chains, and the supporting hardware are what 2003-2009 Toyota 4Runner Internal Engine Parts cover.

 

Timing chain replacement on a high-mileage fourth-gen 4Runner with the 1GR-FE is one of the higher-impact preventive maintenance items available on the platform — a stretched chain produces rattle at cold start and timing variance that affects power and fuel economy before it becomes the noise that finally motivates a repair. Getting the chain done while the engine is apart for another reason is the most cost-effective window for it, since the labor for accessing the front of the engine is the expensive part and the chain itself is relatively cheap.

 

Bearing sets, timing chains, piston kits, and the internal hardware that goes into a fourth-gen engine rebuild are what 2003-2009 Toyota 4Runner Internal Engine Parts cover.
