Parts for your 2001 Nissan Serena-Exhaust mount

2001 Nissan Serena exhaust-mount: what it does and when to replace it

Based on technical sources, an exhaust-mount is absolutely relevant to the 2001 Nissan Serena (C24). The Nissan Serena C24 Workshop/Service Manual (Exhaust System – EX section) shows the exhaust assembly suspended from the body by rubber “insulator” hangers, and the Nissan FAST electronic parts catalogue (EPC) lists these as serviceable components along the pipe, centre muffler and rear muffler. Dealer parts diagrams for the C24 likewise depict multiple rubber exhaust insulators and associated brackets. So yes—the 2001 Serena is fitted with exhaust-mounts from factory.

On a Serena, the exhaust-mounts are those tough rubber insulators that cradle the exhaust and keep it from thumping the floor. Their day job is threefold: carry the weight of the system, isolate engine and road vibration from the cabin, and allow the pipework to expand and move as it heats and cools. That flexibility is why the van stays quiet and comfy on long trips, even with a load of passengers and gear.

Over time, heat, road grime and coastal climates common in Australia and New Zealand can harden, crack or stretch the rubber. When that happens, the exhaust can sit lower, knock on crossmembers, or drone more than it used to. As part of servicing of a 2001-nissan-serena exhaust-mount, it’s smart to inspect them at every oil change and replace on condition—there’s no strict interval, but many need attention somewhere after 150,000 km or when age takes its toll.

• Signs it’s time: sagging tailpipe, clunks over bumps, exhaust touching the body, visible splits or elongated holes in the rubber, or new vibrations at idle.
• Replacement tips: support the exhaust with a jack and timber block, spray a silicone-based lube on the old mounts, and use proper exhaust-hanger pliers if available. Avoid petroleum products on rubber.
• Parts choice: genuine or quality aftermarket rubber mounts with the correct durometer keep NVH close to factory. Ultra-stiff mounts can transmit noise in a family van like the Serena.
• While you’re there: check bracket bolts for corrosion, confirm heat shields are secure, and look for cracked welds caused by long-term droop.

Most C24s run several mounts (often three to four depending on market and exhaust layout). Replacing them is inexpensive preventive maintenance that keeps the exhaust happy and the cabin quiet.

Popular questions about 2001 Nissan Serena exhaust-mounts

How many exhaust-mounts does a 2001 Serena have?
Most C24 models use several rubber insulators along the system—typically three to four, depending on whether the vehicle has different muffler layouts or market-specific hardware. A quick look under the van will show one near the centre section and one or two at the rear muffler, plus any additional supports near the front pipe as fitted.

What happens if an exhaust-mount fails on a Serena?
A failed mount lets the exhaust sag or swing, which can cause knocks over bumps, buzzing at idle, and in bad cases, the pipe contacting the body or stressing joints. It won’t usually strand the driver, but it can damage the exhaust, heat shields or oxygen sensor wiring if ignored, and it can get noisy fast.

Can they drive with a broken exhaust-mount?
They can limp home or to a workshop if the exhaust is supported and not scraping, but it’s best to sort it promptly. Use a temporary strap only as a short-term measure, the correct rubber insulator restores the designed movement and prevents extra vibration and stress.
