2010 Holden Colorado Exhaust Mount: What It Does and When to Replace It

Yes, an exhaust mount is absolutely used on the 2010 Holden Colorado. Technical sources including the Holden Colorado RC Workshop Manual (Exhaust System section, 2008–2012), the Isuzu TFR/TFS Service Manual for the same platform, and the GM Global EPC parts catalogue all show multiple exhaust hangers/mounts supporting the system from the downpipe back to the tail section. These documents detail rubber-isolated hangers fixed to chassis brackets to control movement, vibration and height of the exhaust.

On a hard‑working ute like the 2010 Colorado, those rubber exhaust mounts pull plenty of weight. Their main job is to suspend the exhaust so it sits at the right height and angle, soak up vibration, and stop the system knocking on crossmembers, leaf springs or the tub. They’re simple bits of kit—rubber or rubber-with-bushing loops on steel pegs—but they make a big difference to comfort and longevity.

Over time, heat, oil splash, off‑road flex and towing can crack or stretch the rubber. Once a mount sags, the exhaust can rattle at idle, thump over bumps, or sit skew‑whiff and stress the flanges and welds. That’s why most workshop schedules recommend inspecting mounts whenever the ute is up on a hoist for routine servicing or before long trips, especially if it’s seen corrugations or carries a towbar.

• Tell‑tale signs: dull thuds over bumps, a tinny rattle at start‑up, visible sagging or perished rubber, soot marks where the pipe has contacted the chassis, or a tailpipe that’s not centred.
• Good practice: replace mounts in pairs on the same section so the system sits level, use a dab of silicone spray to slip new rubbers on, and check clearances around the diff, spare and towbar after fitment.
• Service interval: there’s no fixed kilometre change, but it’s smart to inspect every service and typically replace at the first sign of cracking or elongation. Utes that tow or go off‑road may need mounts sooner.

Owners chasing a tighter feel can consider heavy‑duty or polyurethane hangers, but they can transmit a touch more vibration. Whichever way they go, keeping fresh, correctly sized mounts on the 2010 Holden Colorado prevents annoying knocks and helps protect the exhaust, sensors and brackets from premature wear.

Popular questions

How often should exhaust mounts be replaced on a 2010 Colorado?
There’s no strict mileage, because heat and use matter more than the odometer. For a daily‑driven ute, inspect them at every service. If there’s cracking, stretching, or the exhaust has shifted, replace them straight away. Vehicles that tow, work off‑road or see lots of corrugations may need new mounts sooner.

What are the symptoms of a failing exhaust mount?
Common giveaways include a thunk over bumps, a buzz or rattle at idle or on start‑up, and a tailpipe that looks off‑centre. Underneath, look for perished or torn rubber, elongated holes and shiny or sooty contact marks where the pipe has been touching the chassis or suspension.

Are heavy‑duty or polyurethane hangers worth it?
They can be a good pick for towing or rough tracks as they resist heat and stretching, helping the exhaust stay put. Expect a slightly firmer feel and sometimes a touch more vibration. If comfort is the priority, quality OE‑style rubber mounts are still a great choice.
