The timing chain in your vehicle is an important part that provides an essential function. The thing is, however, that in order to run correctly this chain needs to be at a specific tension, not too tight and not too slack, or else performance is reduced and serious damage may even result. To keep the chain at a correct tension a car timing chain tensioner is used, which provides pressure to the chain and helps it keep a specific tension. The part itself is not overly complicated and is relatively easy to maintain, with just a few small replaceable parts.
Car timing chain tensioners are relatively simple in design and easy to understand, so DIY mechanics often like to service their own. A few simple parts make up the design, most of which can be replaced with relative ease. The whole car timing chain tensioner rarely needs to be completely changed. More casual drivers, however, may wish to enlist the help of a professional mechanic to be sure the job is done one hundred percent correctly.
The small replaceable parts of a car timing chain tensioner are not expensive at all, costing hardly the amount of the essential function served by the timing system. Removing the parts and replacing the parts is likewise not time consuming or especially difficult, and guides can be found online. However, if the whole car timing chain tensioner system needs to be replaced, the cost will be higher and more effort required. Do not put off replacing car timing chain tensioners for too long, since if the chain becomes too loose there is a possibility of fairly serious and dangerous damage occurring, which may result in much more costly repairs.
