How much does it cost to replace a serpentine belt on a Toyota Tundra?
For a typical Toyota Tundra, a serpentine belt replacement usually falls around the low hundreds, commonly between about $100 and $300; belt-only jobs are cheaper, while replacing the belt plus tensioner/idler can push toward the high end. Exact pricing depends on belt type, labor rates, and your location.
Cost components
Costs typically split into parts and labor. The price ranges below reflect common components you might encounter on a Toyota Tundra.
- Serpentine belt: $25-$75
- Tensioner pulley: $20-$80
- Idler pulley: $15-$60
- Belt kit (belt plus tensioner and/or idler): $60-$180
- OEM vs aftermarket parts can swing prices up or down by roughly 20-50%
In belt-only replacements, parts usually total roughly $60-$150, with additional costs if a belt kit is used.
Labor time and rates
Labor costs depend on where you are and the shop's hourly rate. Here is what a typical replacement looks like in practice.
- Typical labor time: 0.5 to 1 hour
- Average shop rate: $75-$125 per hour (rates can be higher in major cities)
Labor adds roughly $40-$125 for most belt replacements, depending on the rate and time required.
Cost scenarios
When you consider both parts and labor, these scenarios are common:
- Belt replacement only: roughly $60-$190 for parts plus $40-$125 for labor, total around $100-$315
- Belt replacement with tensioner and/or idler: parts up to $150-$250 and labor $40-$125, total around $190-$375
Note that dealership quotes can be higher, and if additional issues are found (such as a seized tensioner or damaged pulleys), costs can rise further.
How to save and what to ask
Get multiple written quotes, ask if the quoted price includes both belt and any required pulleys or tensioners, and consider whether the shop will replace only what’s needed or push for a full belt kit. If you’re comfortable with tools, you can save by performing a DIY belt replacement with proper precautions and torque specs.
Summary
Summary: Replacing a serpentine belt on a Toyota Tundra generally costs in the low hundreds, with typical ranges around $100-$300 for belt-only jobs and up to $350-$450 when including tensioner/idler parts or in high-cost regions. Always get an itemized quote, and consider whether a tensioner replacement is advisable to avoid future failures. A DIY approach can reduce costs but requires mechanical skill and proper safety procedures.
