rivers, just because your Stryker has wheels doesn’t mean you can start it
or shut it down like your POV. If you try, you’ll probably be asking your
mechanic to replace the turbocharger real soon.
Startup
Gravity drains oil out of the turbocharger when the Stryker’s been sitting
for a while. So make sure you idle the vehicle for 30 seconds or so before
moving out. And don’t rev the engine while you’re waiting!
Idling lets enough oil circulate to the turbocharger’s bearings to prevent
any damage.
Shutdown
The turbocharger continues to spin for a short time after shutdown. Of
course the oil stops circulating as soon as you shut off the engine. That means
you need to cool down the turbocharger before shutting down the engine.
Run the engine at low idle for at least 3 minutes before shutdown.
The circulating oil cools the turbocharger so that it doesn’t overheat after
the engine is shut down.

Stryker…
Drain Hub Oil
Safely
Dear Editor,
No mechanic looks forward to draining the Stryker’s wheel hubs. As soon
as you remove the drain plug, oil gets all over the hub, tire and ground.
It’s not only a big mess, but an environmental problem as well if you don’t
clean it up properly.
I’ve come up with a homemade tool that puts a stop to that problem. It’s a
special trough made of 24 gauge steel that hooks onto the hub and channels
the oil straight into a can or drip pan with no mess.
Here’s how to make it:
When the tool is finished, curl it slightly to fit under the hub. Then follow the
instructions in IETM 9-2320-311-13&P for draining the wheel hubs.
