Source: https://route66autorepairshop.com/engine-services/drive-belt-replacement Updated: 2026-09-17 Business: Route 66 Auto Repair, 1775 W Foothill Blvd, Upland, CA 91786, (909) 608-7699 Hours: Monday to Friday 8 AM–5 PM, Saturday 8 AM–2 PM, Sunday closed **TLDR:** Your engine may run one **accessory belt** or several **V-belts**. We check each belt and pulley and replace only what is worn, with **correct tension** set. Drive belts turn the parts bolted to the front of your engine: alternator, water pump, power steering pump and AC compressor. Some vehicles use one ribbed belt, while older cars, trucks and many diesels run two or three separate V-belts. Route 66 Auto Repair in Upland identifies which belts your engine has, checks each one and the pulleys they ride on, and puts the replacements on a written estimate first. ## Which kind of drive belt does your vehicle use? Most cars built in the last few decades use one wide, ribbed belt that snakes around every pulley. That is covered on our [serpentine belt replacement](https://route66autorepairshop.com/engine-services/serpentine-belt-replacement) page. Older cars, classic trucks and some work vehicles use narrow V-belts, each running one or two accessories, with tension set by moving a bracket. Drive belts are not the same as a [timing belt](https://route66autorepairshop.com/engine-services/timing-belt-replacement). The timing belt sits behind a cover and keeps the valves in step with the pistons. Drive belts are outside and visible, and they run the accessories. ## Signs a drive belt is due - Cracks across the belt or chunks missing from the edge - A glazed, shiny belt surface that squeals when wet - Battery light or heavy steering after a squeal - AC that blows warm when the engine is under load - Rubber dust or strands around the pulleys ## Our drive belt replacement process 1. **Map the belts:** We note how many belts your engine has and what each one drives, and we check the routing. 2. **Inspect pulleys:** Each pulley is spun by hand for bearing noise, wobble or groove wear before a new belt goes on. 3. **Replace and tension:** New belts are installed and tensioned to spec, whether by a bracket, an adjuster bolt or an automatic tensioner. 4. **Run and recheck:** We run the engine with every accessory on, then recheck tension and alignment before the road test. ## What's included in drive belt replacement - Identification of every accessory belt on the engine - Pulley and bracket inspection - New belt or belts as quoted - Tension set to spec - Accessory load check with AC, lights and steering - Old belt kept to show you ## Need-now or need-later? **Need now:** - A belt that runs the water pump is frayed or cracked through - A belt has already jumped off or is shredding **Need later:** - Light surface cracking with good rib depth - A belt on a secondary accessory with minor glazing ## How pricing and timing work Belt price scales with how many belts your engine has and what must come off to reach the inner ones. On multi-belt engines, the inner belt often means removing the outer ones first, so replacing them together can save labor. We show you both options on the estimate. AAA members get 10% off parts and labor, up to $75. Belt jobs are often same-day when the board allows. ## Aftercare New V-belts can stretch a little in the first few hundred miles. If you hear a chirp on a cold morning, bring it in for a quick retension. Automatic tensioners do not need this. For a broader belt and hose look, ask about a [belt condition inspection](https://route66autorepairshop.com/diagnostics-and-inspections/belt-condition-inspection). ## Frequently asked questions ### Should I replace all my V-belts at once? If they are the same age and the inner belt is worn, usually yes, since the outer belts come off anyway. If one belt was replaced recently and still looks good, we leave it and note that on the estimate. ### What happens if a drive belt breaks while driving? It depends on what the belt drove. Lose the water pump belt and the engine can overheat within minutes, especially on a grade. Lose the alternator belt and the battery drains until the car stops. Pull over safely and call us at [(909) 608-7699](tel:+19096087699); we accept tow-ins. ### Is a fan belt the same as a drive belt? Yes. Fan belt is the older name, from when the belt also turned the radiator fan. Many trucks still drive a mechanical fan this way, so a worn belt there can also affect cooling. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
