February 9th, 2011 10:26 PM #1Does anyone else think there is an inherent problem with Carens 2007 turbo charger? Mine failed right after the 3rd year. And again after 1 year with the replacement turbo charger (a free replacement part from KIA), the same problem happened.
I have also a friend who bought his carens a couple of months ahead of me and had a similar experience. According to him, he learned from other mechanics that we should avoid revving the engine prior to turning it off to ensure the turbo is receiving equitable oil flow relative to its instantaneous power.
Is there truth to this advice? Anybody else have this issue?

You should cool down your engine for about 2-3mins before you turn off your engine.

palagay ka na lang turbo timer just to be sure. pero kung paulit ulit na nasisira may defect tlaga yan. designed naman kasi din na di na kailangan ng cool down yan.

February 11th, 2011 11:51 AM #6Don't rev the engine before shutting it down, especially on turbocharged vehicle.
Why? The turbo may still spin due to the momentum created by revving the engine ( the turbo also increases rpm when you rev up) and then no oil supply to the lubricate the bearings because the engine is shut already. This causes failure of the bearings of the t/c.
Also you need to cool it down especially on long drives where you are always on hiway speeds. 3 min. is enough before shutting it off and dont rev it, keep it on idle. Or before you reach destination you can begin slowing down so it wont take that long for cooling down. Temperatures on engine can reach suddenly higher when you suddenly shut it. The oil film remaining on the bearings of t/c may overheat and then become coked that also lead to failures.
But it is a chinese vehicle you can get spare parts from lazada or shopee right?
