Early models used a dipstick with a single o-ring seal. These are prone to leaking. Volvo has superseded the early style in to the later style but both the dipstick and the tube will need to be replaced if your Volvo is equipped with the earlier style.
The later style dipstick is thicker at the top and will not fit in the earlier dipstick tube. If you have the early style dipstick, you will need to also replace the tube.
Aftermarket parts are a reasonably priced and good alternative to OE products. We often supply aftermarket products in place of OE parts that are no longer available as well.
Some items will be better than stock or considered an upgrade from the OE design in the aftermarket brand.
Other items will work as a less expensive alternative to stock.
We will not sell a product that we do not believe in, so rest assured you are fine with the aftermarket brand in most applications!
If you have any questions, contact our customer service team to advise on the best aftermarket products for your Volvo.
