False Economy!

That's when you refuse to replace the tensioner when replacing the cambelt on your engine.

The tensioners in our product portfolio are all genuine OE items.
You will have to choose which tensioner is installed on your car. Please have a look at below table to determine what tensioner you'd need:

Engine Numbers

Generally, engine numbers higher then the above have automatic cambelt tensioners. Anything lower will have a manual tensioner.
