Frequently Asked Questions
How do I know if I have the EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS) engine?
Check the VIN / data plate in the engine bay - the line marked ENGINE shows your code (the example plate above reads EF-NS; yours must read EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS)). This part fits the EF-GS (EFGS) or EF-ZS (EFZS) or EF-RS (EFRS) engine only, so confirm the code before ordering.
Should I fit a new belt with the tensioner?
Yes - never put a used belt back on a new tensioner. Replace them together and set tension to spec for the listed engine.
Should I replace the belt at the same time?
Yes - never put a used belt back on a new tensioner; do them together.
