TBM Posted August 16, 2007 Report Share Posted August 16, 2007 Sorry for the n00b question, but...Would a 98 S70 T5 turbo need cooling after a "hard" drive? I did a search and couldn't find a satisfactory answer.Thanks in advance... Link to comment Share on other sites More sharing options...
evilb Posted August 16, 2007 Report Share Posted August 16, 2007 Every turbo car needs a cool down period, especially if the turbo is only oil "cooled". If it is water cooled then that time is less, but it doesn't hurt to let it sit there and cool off. You don't want oil baking in the turbine bearing. Basically take the lead out of your shoe for the last few minutes of your drive. Link to comment Share on other sites More sharing options...
TBM Posted August 16, 2007 Author Report Share Posted August 16, 2007 So the cooling should be done after every drive? Or just after "hard" driving. How hard is hard enough? Link to comment Share on other sites More sharing options...
Mesoam Posted August 16, 2007 Report Share Posted August 16, 2007 just drive light footed for 5 mins or so (no boost), then idle for 30 sec (just to let it spin down) Link to comment Share on other sites More sharing options...

It's wired inline with your ignition and keeps the car running for about 60second or more AFTER you have turned the ignition off anf locked the doors. This gives the turbo time enough to re-circulate oil and/or water to cool it down and prolong the life of your turbo.It's all in personal opinion if the Water cooled Cars need it or not, but if your not going in that direction a general rule of thumb is if you are running the car hard and getting the turbo hot, drive for a few miles without boosting and give the turbo some time to cool off before turning off the ignition.

S60RDUDE Posted August 16, 2007 Report Share Posted August 16, 2007 WE do not need a turbo timer on the Volvo cars the cooling is a lot better than most vehicles. Our Inter cooler and cooling systems is suffice to cool the turbo down enough. If you are driving hard and get to a stopping point let it idle for 30 seconds NO AC on and let the fan cycle through fully. Than shut it off. According to the boys at IPD unless you are going up hill on a steep incline for miles at a time your turbo should not be getting scorching hot.

RedTurbo850 Posted August 16, 2007 Report Share Posted August 16, 2007 As you get off the freeway locally, drive it regularly and that should be sufficient to cool the turbo. Link to comment Share on other sites More sharing options...
