Before I discuss the factors in detail, let’s see how to reuse a timing belt tensioner.
How to Reuse a Timing Belt Tensioner?
Reusing a timing belt tensioner can be a great way to save money on car repairs. It is important to take the time to properly reinstall the tensioner and ensure that it is functioning correctly. This guide will provide the steps necessary to do so.
Tools Needed
- Screw drivers.
- Socket set.
- Torque wrench.
- Combination wrenches.
- Jack and Jack stand.
Step 1: Locate the Tensioner
It is usually located at the front/back side of the engine, but the location may vary depending on the engine model. Disconnect the negative cable from the battery. Then unscrew the bolt holding the tensioner in place to unmount it.
Worth adding, some people think that a timing belt may drain the battery but no it doesn’t.
Step 2: Remove Other Components
In some engine models, you need to disassemble some other engine parts first to get access to the timing belt tensioners. Such as the alternator/belt, power steering pump, water pump, air conditioning compressor, etc. Hence, remove them first.
Step 3: Remove the Tensioner
Be careful not to damage the timing belt while removing the tensioner. Check the tensioner for any signs of wear or damage. If there is any, replace the tensioner. The removal process may vary depending on the type of vehicle you are using.
Here’s a video you can watch to have a general idea of the tensioner removal process.
Step 4: Clean the Tensioner from Debris
Clean the tensioner and lubricate the bolt with any non-detergent petroleum-based oil before reinstalling it. If there’s oil or water contamination in the tensioner, it will affect proper grip and cause slippage.
Step 5: Reinstall the tensioner
Finally, reinstall the timing belt tensioner in the same position it was removed from.
Follow the manufacturer’s instructions for tightening and adjusting the tensioner bolts. To ensure the tensioner is functioning correctly, perform a test run before driving.
Following these steps should help you safely and correctly reuse a timing belt tensioner. Remember that the above steps are general instructions for the replacement process. The replacement procedure may depend on your car model, brand, and engine type.
Your vehicle may have spring-loaded or hydraulic tensioners. Watch this video to learn how to set tension on spring-loaded timing belt tensioners.
If you’re going to reuse the hydraulic tensioner, make sure to bleed the air out before installing them.
Additionally, adjusting the proper tension is complex and requires the highest precision. In case you don’t know how to adjust the tensioner, here’s a video on adjusting the timing belt tension without any special tools.
Alternatively, you can contact an automotive expert or take your vehicle to the nearest service center to adjust the belt tension properly. Now, let us move on to the factors.
Summary:
To reuse the tensioner, first, gather the required tools and Locate the tensioner first, according to the engine type. Then, before removing the tensioner, disassemble other components if needed. Clean the tensioner by removing all debris. Finally, reuse the tensioner and adjust the proper tension.
Reusing Timing Belt Tensioners: What to Consider?
As I have mentioned earlier, you should keep some critical factors in mind when reusing the timing belt tensioner. Here are the factors discussed in detail below.
Factor 1: The Age Of the Tensioner
Make sure the timing belt tensioner you want to reuse is not too old and has some lifespan left in it to reuse. Although there’s no ideal timeframe, a belt tensioner should ideally last between 40,000-70,000 miles; you may need replacement after this period. (2)
In case, you’d want to know whether a timing belt has a date on it, here you’ll find that.
Factor 2: The Type of Tensioner
Whether you can reuse the timing belt tensioner depends on the type of tensioner. Ensure the tensioner you try to reuse is compatible and still reusable with the vehicle. Also, double-check the owner’s manual for the recommended tensioner type.
Factor 3: Worn-out Tensioner
Always visually inspect the tensioner you are trying to reuse for physical damage or cracks. Just like any other automotive parts, tensioners tend to lose their capability. Hence, ensure its tension adjustment functionality is working properly.
Factor 4: Overheating Tensioner
If the tensioner you want to reuse has an overheating issue due to friction, refrain from reinstalling it to the vehicle. Tensioners can overheat for many reasons, such as excess friction/load, wear and tear, lack of adequate lubrication, and high torque.
Factor 5: Faulty Tensioner Spring
In automatic spring-loaded tensioners, the spring might be weakened or damaged over time. The spring creates and maintains the tension by providing extended force when the timing belt is stretched. So, ensure it’s in good condition and working properly.
Factor 6: Condition of the Timing Belt
The tensioner helps to maintain the proper grip and tension between the timing belt, so they’re correlated. If the timing belt is worn out or contaminated by leakage, replacing a tensioner won’t help until you fix the timing belt issue. Hence, replacing the timing belt when installing or reusing a tensioner is recommended.
Factor 7: Cost of Replacement
Cost of replacement is another factor to consider while reusing a timing belt tensioner. The cost varies depending on the manufacturers and the type of your vehicle. But the ideal cost of replacing the engine tensioners ranges between $500-$1000 (the entire tensioner kit, including taxes on the parts and labor cost).
However, keep in mind that if you’re reusing the tensioners, you’ll only need the labor cost. If you want to DIY, that can save you a lot of money.
Summary:
While reusing tensioners, you need to consider some factors, such as the age and the type of the tensioner. Also, physical inspection of the tensioner and its overall condition. These inspections are necessary for safety and optimal performance.
Is It Safe to Reuse a Timing Belt Tensioner?
Using a timing belt tensioner is safe only when the bearings are free from visible damage, cracks, and rust; there are no wear and tear and mechanical faults. But it’s generally not recommended to reuse a timing belt tensioner.
Timing belt tensioners are subjected to a lot of wear and tear. Also, over time, they can become less effective at maintaining proper tension on the timing belt. If a tensioner is reused, it may not be able to hold the timing belt in the correct position.
This could result in problems such as belt slippage, engine not starting or misfiring, sudden power loss, and reduced engine performance. Moreover, tensioners are designed to be replaced as units rather than individually for optimal performance.
The tensioner unit includes the timing belt, the serpentine belt, idlers, the water pump, etc. That’s why experts suggest replacing the entire kit rather than just the tensioners.
Hence, consult a mechanic or refer to the manufacturer’s recommendations if you are unsure whether to reuse your timing belt tensioner.
Summary:
Timing belt tensioners are subject to a lot of wear and tear and can become less effective at maintaining proper tension on the timing belt. Reusing a timing belt tensioner is generally not recommended.
