Acura TLX Timing Belt Replacement & Repair Service

Advice On Your Quote

1. Water Passage + 2 Gaskets Replacement

Original Quote: $1,322.69

Our Research:

• Labor: 1–3 hours
• Parts: 2 gaskets ($10–$50 each)
• Water passage part: (not priced, but this usually isn’t an extremely expensive piece for a TLX)

Analysis:

• Given even a high labor rate ($160 x 3 = $480) and a generous estimate for gaskets ($100 total), you’re nowhere close to $1,322.
• Possible explanation: Either the water passage itself is extremely pricey for your model, or there may be a big markup (often the case at dealerships or some local shops). Labor hours might be padded.
• Common upsell? Not usually unless the leak is minor and the shop is suggesting replacement instead of a lower-cost repair. Always ask to see the leak or for a photo.
• Advice: This price looks high based on our research. Unless there’s something special about the part included here, I’d recommend getting a second opinion from a reputable independent mechanic. If you’re handy, you could even check rockauto.com or similar for parts pricing just to compare. If your coolant leak is obvious and the water passage is cracked or corroded, repair is likely necessary—just not for this much.

2. Timing Belt Replacement (with Water Pump, Drive Belts, Tensioner, Coolant)

Original Quote: $1,649.95

Our Research:

• Labor: 4–6 hours
• Parts:
  • Timing belt kit: ~$230
  • Water pump: $600–$720 (high perf. part? At the top end)
  • Drive belts: $50–$200
  • Tensioner: ~$275
  • Coolant: $20–$50

Analysis:

• Let’s max it out: Parts total can get close to $1,500 (if they use all top-of-the-line branded parts).
• Labor at 6 hours x $160 = $960 (worst case).
• Many TLX timing belt jobs (all-in with water pump and coolant) typically run $900–$1,500 at independent shops, sometimes a bit more at Acura dealers.
• Common upsell? Shops sometimes suggest changing items like tensioners or all belts "while we're in there"—which is actually smart preventative maintenance for a timing belt job on a higher-mileage Acura with a V6. This isn’t a bolt-on upsell; most reputable mechanics will tell you to do these together, since labor overlaps and you avoid bigger future problems.

Advice:

• The price here is at the higher end of normal, but not outside what we’d expect for a 6-cylinder Acura at a branded shop. If they’re genuinely replacing all listed parts, it’s a big, labor-intensive job. Local independent shops may do it for less—could be worth a call for comparison. But the list itself makes sense, and if you plan to keep the car, doing water pump/tensioner/etc is smart.
• Make sure they’re quoting you for new, quality parts—not just charging for them. Ask if any of the drive belts or tensioners really need it, but doing them all isn’t a gimmick here.

Bottom Line:

• Water passage quote is high—get a second opinion or compare part prices. If there’s a detailed explanation for the cost, ask for it.
• Timing belt package is fair but on the high side—worth getting a second quote, but not wildly out of range for an Acura with all parts included.

If you’re not sure about a part or why something needs replacing, ask your mechanic to show you the worn or leaking part. Any good shop will do this and it puts you in control.

You’re definitely not being quoted anything close to the value of the car, so this isn’t a “total it and walk away” situation—it just pays to keep them honest on price and parts.
