Volvo S80 2.4T New Engine Mounts

When you have an older car, always think about replacing the engine mounts. They are almost always made of rubber, which becomes brittle over time due to aging/drying out.

I replaced all the engine mounts, which tightens up handling and improves performance and reduces strain on components like the exhaust, as the engine swivels way less. Highly recommended!

Volvo S80 2.4T Old vs New Coolant Expansion Tank

Bought a new Febi coolant expansion tank as the old one was tatty, old and brown.

Looks better in the engine where no one else looks, but me 🙂

Volvo S80 2.4T Changing Spark Plugs (NGK K20TT 4604)

Fitted some fresh new plugs and decided to try NGK copper plug instead of Volvo OEM Iridium plugs. They work great and cost next to nothing. Decided to try NGK K20TT 4606. Double checked the gap to be sure, they are correctly preset for the Volvo S80 2.4 / 2.5T.

Still have to get used to swapping out 5 spark plugs instead of the “usual” 4.

Volvo S80 2.4T Replacing the Upper Engine Mount with SuperPro Polybush

I noticed that when lifting off (like shifting), there was a lot of movement / play in the engine / gearbox. So when I inspected the upper engine mount, I found the root cause rather quickly. The rubber deteriorated and there wasn’t much left of the original rubber bushing.

Having read the other options, like fitting a polybush, I went with the SuperPro version which looked like a good bit of kit. Mounting the new polyurethane kit was quite a breeze. Fortunately, the original bushing has a plastic ring 🙂 The SuperPro kit consists of 2 pieces, which makes the mount very easy to replace.

Result: a much better shifting car, putting the power down goes a lot better now. I will also replace the bottom gearbox mount with a polyurethane version soon.

Very easy job to do at home. This also applies to the S60 and V70, as these are quite identical.
