Heater and radiator hoses aren't designed to last forever. They should be, but they just aren't. If yours are bulging, cracking or distorted, they're nearing the end of their effective life. Squeeze each one: if it's become either brittle or too soft, put it on the 'replace' list.
Avoid the embarrassment (oh yeah - and the inconvenience) of being stranded by the side of the road for something as simple as a blown hose. Also - consider replacing the clamps too, with smooth ABA style clamps instead of the more common cheese grater style.
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.
