How We Replaced the Cambelt and Water Pump on a Dacia Sandero

This Dacia Sandero came into Star Garage Mansfield right on time for a critical bit of maintenance — its cambelt and water pump replacement.

Like many modern cars, the Dacia Sandero uses a timing belt that controls engine timing. If this belt fails, it can cause serious damage to the engine. That’s why replacement is recommended every few years or after a set mileage — whichever comes first.

Here’s how we carried out the job and why keeping on top of cambelt servicing is essential for engine health.

Meet the Car: Dacia Sandero 1.0 Petrol

The owner brought the vehicle in with around 65,000 miles on the clock. It was still running well — no noises or warning lights — but was due its timing belt change based on mileage and age. The customer wisely chose to do it preventatively.

We also advised replacing the water pump at the same time, since both components live in the same area of the engine and are subject to similar wear. This saves on labour costs and avoids future failure risk.

When Does a Dacia Cambelt Need Changing?

Dacia’s own guidance is to change the timing belt once the car is more than five years old or has covered more than 70,000 miles — whichever comes first. Age counts as much as mileage here, because the rubber hardens and loses its grip on the pulleys even on a car that has barely been driven.

That is why a low-mileage Sandero sitting on a driveway is not automatically safe. We see belts on older cars that look fine from the outside but are already glazed and cracking between the teeth.

A few things push the job forward rather than back:

• Short, cold journeys. The belt and tensioner spend more of their life cold and under load.
• Unknown or gapped service history. If there is no stamp or invoice for the belt, assume it has never been done.
• Any oil or coolant leak near the timing cover. Both attack the belt material.
• A car that has stood unused for a long period. Belts age on the shelf as well as on the road.

Dacia also advise taking the opportunity to check the water pump while the timing end is stripped, which is exactly what we did on this car — the pump is driven by the belt and sits behind it, so the labour is already paid for once. Always check the schedule for your own engine and model year, as the interval can differ between the petrol and diesel units.

1. Stripped the timing side of the engine
We removed the covers and ancillaries to access the timing belt, crank pulley, tensioners, and water pump.

2. Fitted new cambelt kit and water pump
We installed a full OEM-spec timing belt kit including new tensioners and idlers, plus a brand new water pump with fresh coolant.

3. Rechecked engine timing and tension
We rotated the engine by hand and checked timing alignment using the correct locking tools. Once perfect, we torqued everything to spec.

4. Reassembled and tested
We rebuilt the engine side, topped up coolant, ran the engine to temperature, and checked for leaks and noises.

Why It Matters

Timing belts are one of the most important service items on your car. If they snap, they can bend valves, damage pistons, and destroy the engine — often costing more to fix than the value of the car.

Replacing the cambelt and water pump on time is a smart, cost-effective move. It keeps your car reliable and avoids surprise breakdowns. In this case, the Dacia Sandero left our workshop running perfectly with years of worry-free driving ahead.

One of the most satisfying moments?

Knowing this customer will avoid a major engine failure by doing the job before the damage happens.
