Good To Know

Q: Does this replace my original tensioner guide? A: Yes, it references OEM part number 420236501 and is built as a replacement for that guide. Confirm your engine code before ordering.

Q: Can I install this myself? A: It is a straightforward part to swap during top-end service, but timing components require correct alignment on reassembly. Have a service manual on hand if you are not experienced with engine timing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
