Good evening everyone,
I have a solution for everyone on the topic of bearing life for Garrett turbos for their 930's.
The system works as follows: A time delay relay starts a very small water pump on engine shut down. The pump draws coolant from a remote tank and through the water coolant passage. From their, the coolant passes through a heat sink (small radiator) and back into the coolant tank.
The time delay relay can be set from 5 seconds to 10 minutes. The pump draws only 3.5 amps at 12v dc. and moves enough coolant to stop the heat soak into the bearing cartridge. I will be intalling this system on my 930 soon.
