Parts for your 2005 Honda Stream-Drive belt

2005 Honda Stream drive-belt: what it is, what it does, and when to swap it

Yes, the 2005 Honda Stream does use an accessory drive-belt (often called a serpentine or auxiliary belt). This is documented in Honda’s Workshop Manual for the Stream RN3–RN5 series under Alternator/Drive Belt Inspection and Adjustment, reflected in Honda’s Electronic Parts Catalogue listings for “alternator/air-con/power-steering belt”, and backed by aftermarket catalogues from Gates and Dayco that specify auxiliary belts for both the 1.7-litre (D17) and 2.0-litre (K20) engines.

On a 2005 Honda Stream, the drive-belt’s job is to spin the alternator to keep the battery charged and the electrics happy, run the air-con compressor for cool air on hot summer drives, and turn the power-steering pump for easy, one-finger parking. It’s a simple rubber belt wrapped around a few pulleys, but it earns its keep every time the engine’s running.

This belt isn’t the same as the timing belt or timing chain. The timing component lives under covers and keeps the engine internals in sync, while the drive-belt sits up front and powers accessories. Because it’s exposed to heat, dust, and day-to-day use, the drive-belt is a wear item and should be inspected regularly as part of routine servicing.

A sensible check interval is every 12 months or 20,000 kilometres. In Aussie and Kiwi conditions, many owners budget for replacement around 90,000–120,000 kilometres or 5–7 years, sooner if there’s any noise or visible wear. If the belt squeals on start-up, the battery light flickers, steering goes heavy at low speed, or the air-con cools poorly at idle, it’s time for a look under the bonnet.

• Check for cracks between ribs, glazing (shiny patches), fraying, missing chunks, or contamination from oil/coolant.
• Listen for chirps or squeals, especially with electrical load or A/C on.
• Inspect the tensioner and idler pulley for smooth, quiet operation.

When replacing, use a quality belt that matches the engine variant (1.7 D17 or 2.0 K20). On some Streams there’s an automatic tensioner, others use a manual adjuster—either way, correct tension is crucial. A belt that’s too loose slips and squeals, too tight can punish bearings. It’s smart to replace a tired tensioner or noisy idler at the same time, and follow the routing diagram under the bonnet or in the manual. Most competent home spanner-spinners can manage the job, but any workshop familiar with Hondas will knock it over quickly and check alignment while they’re at it.

Does the 2005 Honda Stream have both a drive-belt and a timing belt/chain?

Yes. The accessory drive-belt runs alternator, A/C and power steering. Engine timing is separate: the 1.7-litre D17 uses a timing belt, while the 2.0-litre K20 uses a timing chain. They serve different purposes and have different service needs.

How often should the drive-belt be replaced on a 2005 Honda Stream?

Inspect yearly or every 20,000 km, and plan replacement around 90,000–120,000 km or 5–7 years. Replace sooner if there’s cracking, glazing, squeal, or accessory performance issues. Local climate and driving style can nudge that interval earlier.

What are the signs the drive-belt needs attention?

Squealing at start-up, flickering battery light, heavy steering, weak A/C at idle, or visible cracking and fraying on the belt. Any of these are a cue to check belt condition and tension, and to inspect the tensioner and idler pulleys.
