2008 T&C PS system air bleeding process
 

Hey guys,

Just replaced a low pressure ps hose and wanted to know if there are any special techniques to bleeding the system to get the air out and the pump noise to subside. Is it still the same as old school of filling up the reservoir then turning the steering wheel lock to lock several times meanwhile adding fluid until the level remains steady then starting the vehicle and doing the same lock to lock, refill, etc until the fluid level remains full. I partially filled the system (ran out of fluid and needed to get more), did several lock to locks of the steering wheel, then started the vehicle but the noise was very loud and got even louder whenever I tried to turn the wheel so I shut it down until I could at least get enough fluid to fill it and continue with the process. I saw some Youtube videos also that mention you have to do a vacuum bleed with today's vehicles vs just turning the steering wheel back and forth. Is this really necessary. Thanks for any info so I don't kill the pump prematurely.

The only recommendation I've seen on the later models is to hold the steering at full lock for 3 to 4 seconds before turning it in the opposite direction. Otherwise, the procedure is the just the same as its always been!

Thanks. Just filling the fluid up to the full level and turning back and forth lock to lock a few times made all the difference. I had seen some youtube videos of using a vacuum pump to bleed the system so I was wondering. Turned out to be unnecessary for my application and old school did it just fine. Nice and quiet now.

Yeah I've seen a few strange videos on Jeeps which would have you vacuuming the lines. Not sure where that idea came from but never had to do it myself!
