Hello I am looking into a newer Volvo and it seems that many of their models come with a lowpressure turbocharger with intercooler as standard equipment. I want to know if anyone has had a Volvo turbocharger tragedy or if they have not given any trouble yet (knock on wood) If anyone has had a major problem with their newer Volvo please elaborate on that as well.<P>-Poritz

I shared your concern over turbos as well. According to my local dealer, they have not replaced a turbo on a 93 (first year of 850) or newer unit. The watercooled turbos are very durable. Just keep that oil changed.

I think Matt (aka "Prospero") had to replace the turbo on his 850, but it had well over 100K miles. Any watercooled turbo (all '87 and newer Volvos have watercooled turbos) should last a minimum of 100K, with many lasting 150K or more.<P> <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by RedS40ASR:<BR><B>..they have not replaced a turbo on a 93 (first year of 850) or newer unit.</B><HR></BLOCKQUOTE><P>I bet they'll never replace a turbo on a '93, since it wasn't available that year. <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"> But still, that's good to hear that they are lasting a long time.<P>

Most turbo's die in the first 15K miles or after 100K miles.<BR>I saw one cracked turbo with 150K on it and I hear of a new V70T5 and a S60 2.4T with a broken turbo, both within 15K miles :)

My 83 242 has 256,000 km on it and it still has the original oil cooled Turbo, AND its done a lot of mountian driving. <P>I change the oil every 7000 km and after a hard drive I idle it for 2 minutes before turning it off.<P>Jay

<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by devalmyth:<BR><B>this is off the point, but y do's the oil have to be changed reguly with turbos compared to non-turbos???</B><HR></BLOCKQUOTE><P>The turbo creates a LOT of heat for the oil to take, which is why there's an oil cooler on the turbo cars. Petroleum based oil will start to break down sooner than synthetic oil as a result of the high heat. The breakdown leads to sludge, and if the turbo isn't cooled sufficiently, the oil cokes up inside. If the oil isn't changed reguarly at short intervals, it can be very bad for the long term life of the turbo, particularly if it's not watercooled.<P>The cool down period of idling the car allows oil to continue flowing through the turbo while it's not under load. When the engine is finally shut off and the oil stops flowing, the turbo should be cool enough that it won't burn up the oil inside.<P>With a watercooled turbo, there's the additional help of the water to cool the turbo, in addition to the oil. Cool down time is still very important, but it doesn't take as long.<P>Synthetic oil can be used for long change intervals in a turbo because it doesn't break down as easily as petroleum oil. In a non-turbo car, the oil doesn't get as hot, so it tends to last longer.<P>
