Parts for your 2006 Honda Stream-Timing belt kit

2006 Honda Stream timing-belt-kit — is it actually needed?

Short answer: for most 2006 Honda Stream variants, a timing-belt-kit isn’t relevant because these engines use a timing chain, not a rubber belt. Honda’s own workshop manuals and parts catalogues for the second‑generation Stream (launched in 2006, chassis codes RN6–RN9) specify chain-driven cam timing on the 1.8‑litre R18A i‑VTEC and 2.0‑litre engines. Likewise, the widely used K‑series 2.0‑litre (seen in late first‑gen Streams) is chain‑driven. Only the earlier D‑series 1.7‑litre (D17A) from the first‑generation Stream used a belt. So for a 2006‑build Stream that’s the newer RN6/RN7 most Kiwis and Aussies see as a JDM import, a timing-belt-kit won’t apply.

This lines up with Honda technical references: the R18A i‑VTEC family is chain‑driven, K‑series engines are chain‑driven, the older D‑series is belt‑driven with a scheduled replacement interval. Many 2006 cars on the road are the second‑gen RN6 with R18A, meaning no belt service is called for in the factory maintenance schedule beyond inspection. If someone’s got an early‑2006 first‑gen car with the D17A, that’s the outlier where a belt kit is correct — but that’s effectively a previous model generation.

Why Honda didn’t use a belt here comes down to durability and lifetime service expectations. A metal timing chain runs in engine oil, designed to last the life of the engine under normal use, whereas a rubber belt degrades over time and kilometres and must be replaced at set intervals. That’s why you won’t find a “timing-belt-kit” on the parts list for RN6/RN7 Streams, instead you’ll see chain, guides and a hydraulic tensioner.

If the 2006 Stream in the driveway is chain‑driven, owners should focus on good oil and filter changes (right spec, right intervals). Clean oil keeps the chain, guides and VTC mechanisms happy. Listen for chain rattle on cold starts, watch for fault codes related to cam/crank correlation, and sort oil leaks promptly. If a chain service is ever required at high kilometres, the typical shopping list is the chain, guides, tensioner, cam/crank seals and fresh sump oil — but that’s uncommon with regular servicing.

• R18A 1.8 i‑VTEC (RN6/RN7, 2006→): timing chain
• K20 2.0 i‑VTEC (late first‑gen/selected markets): timing chain
• D17A 1.7 (early first‑gen, pre‑2006 build): timing belt

Technical basis: Honda workshop manuals for RN6–RN9 Stream and engine family documentation show the R18A and K‑series are chain‑driven, first‑gen D‑series uses a belt with scheduled replacement. That’s why a timing-belt-kit generally isn’t used on a 2006 Honda Stream.

FAQs

Does a 2006 Honda Stream have a timing belt or chain?
Most 2006 Streams (RN6/RN7 with the R18A i‑VTEC) have a timing chain. Only earlier first‑gen cars with the D17A 1.7‑litre used a timing belt. Check the engine code on the build plate to be sure.

How often should the timing chain be replaced on a 2006 Stream?
There’s no routine replacement interval. With regular oil changes, the chain is designed to last the life of the engine. Replace only if there are symptoms like chain rattle, stretch‑related fault codes, or confirmed guide/tensioner wear.

What are the signs the chain or tensioner needs attention?
Cold‑start rattles, poor running, cam/crank correlation fault codes, or metal in the oil may point to chain or guide issues. Have a technician verify with diagnostic checks before authorising repairs.
