The Dayco belt tensioner corresponds to the OE number for PSA 1204.56

Dayco belt tensioner for PSA Groupe 1204.56 with cardboard box

The Dayco belt tensioner for PSA (Peugeot, Opel, Citroen) 1204.56 ensures correct power transmission from the crankshaft to the water pump. This can be switched on and off as required. The water pump only moves the cooling water in the switched-on mode. If it is switched off, the engine can warm up faster, which reduces fuel consumption and exhaust pollution. This also allows the passenger compartment to heat up more quickly in winter. The water pump is activated using the Dayco belt tensioner. This, triggered by an electrical impulse, switches on the water pump by mechanical power transmission.

Where and how to use a belt tensioner?

Belt tensioners themselves can also be used in other belt drives. They can also be found in the following auxiliary units:

  • Generator
  • V-ribbed belt
  • Timing belt
  • Climate compressor

Belt tensioners eliminate the need for manual tensioning, making belt replacement easier. There are two types of belt tensioners. One is fixed and the other is automatic. Fixed belt tensioners are aligned exactly with the belt during installation and keep the same tension on the rollers constantly over time. Automatic belt tensioners, on the other hand, can adjust the tension according to the engine load and operating condition, thus optimising the transmission of power. This is done using a spring or hydraulically. The belt tensioners are supported by various rollers, which also provide the necessary guidance for the belts.

How can a belt tensioner break?

Since vehicle construction is constantly evolving, engine performance is constantly being increased and additional auxiliaries are being added, spare parts are constantly faced with new challenges in terms of material and function. In the case of belt tensioners, these are:

  • Shrinking work areas
  • Higher temperatures
  • Longer replacement intervals
  • Permanent load

The main causes of defective belt tensioners include contaminated and oxidized metal, fractures in the material and bent parts. This means that spare parts such as the belt tensioner should also be of high quality. The Dayco belt tensioner for PSA 1204.56 more than meets these requirements. That's why PSA itself installs Dayco belt tensioners in some of their vehicles. As original equipment the spare part is a testament to the highest fitting accuracy and is available from us at a lower price than if it was originally sold by PSA.

What to consider when installing the Dayco belt tensioner for PSA 1204.56?

As with all belt tensioners, the Dayco belt tensioner also depends on the correct belt tensioning force. It is responsible for the optimum function of the belts. They must neither slip nor jerk under high loads. Even if the Dayco belt tensioner is an automatic belt tensioner, the correct belt tension should be observed during installation. There are already various tension gauges available for this purpose. This means that even car enthusiasts with a talent for manual work can change the belt tensioners themselves.

The installation is somewhat cumbersome and time-consuming due to the ever narrower working areas. If the effort is too high for you, you can of course turn to your trusted workshop at any time. In addition, you can also contact our service team if you have any questions about purchasing the Dayco belt tensioner for PSA 1204.56.
