See How Much It Costs to Replace the Oil Bathed Timing Belt of the Ford Ka with 136 Thousand Km and Know All the Parts Replaced in the Service.
With 136 thousand kilometers driven, the Ford Ka arrived at the workshop for a complex and detailed service. The owner, who has used the original oil throughout the vehicle’s lifespan, faced the need to replace the famous oil bathed timing belt — a component that often generates doubts and high costs in more advanced revisions.
Unlike traditional belts, the oil bathed belt operates within the engine, in direct contact with the lubricant. Therefore, its maintenance requires more care, specific parts, and specialized service.
Tiago, from the channel Carros com Tiago, made a complete video showing the service and the final value.

Why Replace the Oil Bathed Timing Belt?
The oil bathed timing belt has a lifespan determined by the manufacturer, generally between 100 thousand and 160 thousand km, depending on use and revisions.
After this period, the risk of wear increases. Belt rupture can cause serious damage to the engine, resulting in costs far exceeding the value of preventive maintenance.
In the case of this Ford Ka, the owner preferred to perform the replacement before any failure, maintaining a good maintenance history and preventing future problems.
How the Service Was Performed
Replacing the oil bathed timing belt is not a simple procedure. The engine disassembly is extensive, requiring specialized labor and technical knowledge.
It’s not enough to just replace the belt; several other items need to be replaced or checked during the service.
In this specific case, the service included:
- Replacement of the oil bathed timing belt.
- Replacement of a second auxiliary timing belt (some engines have two).
- Replacement of the belt tensioner.
- Replacement of the valve cover gasket.
- Replacement of the service belt.
- Replacement of filters (oil, air, fuel, and cabin).
- Replacement of engine oil (maintaining the original recommended).
- Replacement of the radiator additive.
- Application of a product for internal decarbonization.
All these items are part of a complete review package, ideal for ensuring the proper functioning of the engine after the intervention.
Parts Used and Costs
The prices of the parts vary according to the brand, supplier, and region. In the service performed, quality materials and new items were used. Below, we present the breakdown of costs based on the invoice generated:
- Timing Belt: R$ 1,895.00
- ACDelco Silicone: R$ 120.00
- Engine Oil (4 liters): R$ 240.00 (R$ 60.00 per liter)
- Oil Filter: R$ 60.00
- Air Filter: R$ 60.00
- Fuel Filter: R$ 40.00
- Cabin Filter + Air Cleaning: R$ 150.00
- Radiator Additive (4 units): R$ 180.00 (R$ 45.00 each)
- Valve Cover Gasket: R$ 195.00
- Labor: R$ 1,200.00
- Car80 Decarbonizer: R$ 30.00
- Service Belt: R$ 275.00
Total Maintenance Cost:
The final value of the service was R$ 4,445.00. This amount includes both the parts and the complete labor.
The fact that the car has 136 thousand km emphasizes the need to replace the oil bathed timing belt.
Although the original oil was used throughout the period, the natural wear of the internal rubber, tension, and bearings associated with the belt makes preventive service mandatory.
Neglecting this maintenance can lead to minor failures or total engine loss, which would result in much greater losses.
Why Is Labor Expensive?
The cost of labor for this service is high due to the complexity of the work. The professional needs to disassemble a significant portion of the upper and side parts of the engine, access the internal gears, and make the correct timing adjustments. Any mistake can compromise the engine’s operation and cause serious damage.
Additionally, the assembly requires absolute care with torque, sealing, and cleaning to avoid leaks and ensure optimal performance after completion.
When to Perform Maintenance?
Each manufacturer sets the timeline for replacing the oil bathed timing belt. In the case of the Ford Ka, attention is recommended starting at 100 thousand km, performing visual inspections, and, preferably, scheduling the complete replacement by 140 thousand km. In the case presented, the owner followed the plan correctly, avoiding greater risks.
Is the Investment Worth It?
Considering the risk of a breakdown and the high cost of a potential engine repair, the preventive investment of around R$ 4,500.00 is financially advantageous. Moreover, the car will run safely and calmly for many thousands of kilometers.
The service of replacing the oil bathed timing belt requires not only special tools but primarily technical knowledge of the model and the engine. Seeking workshops with specialized professionals is essential to ensure the result and avoid future problems.
The channel “Carros com Tiago” followed the entire procedure, showing the details and clarifying the most common doubts about this type of maintenance, which is becoming increasingly common in modern engines.
