Cold weather start growl - power steering pump TSB: Solved
« on: January 08, 2015, 09:15:06 AM »
Hey guys, I've noticed that under about 15 degrees my starter sticks for a second before the gear retracts. Today it was 5*F and it took about 2 seconds of grinding before the bendix disengaged which was pretty alarming. Before I burn out the motor, grind all the teeth down on the flywheel or some horrific combination, has anyone dealt with re-lubing a bendix gear for cold weather? I don't think it will see much more 5* weather (fingers crossed)..long story short my other two money pits are out of commission and I am trying my hardest to avoid blowing $200 on the sky.



Probably not much for you northern and midwesterners but around here in philly this is pretty frigid!

It's 0 here in Columbia Station the first thing I would do is check my battery because if it's the original it may be time for a replacement especially if the car is sitting outside or in an unheated garage .

Battery is fine. The car isn't having any trouble starting, it's just the little gear that shoots out stays connected to the flywheel longer than it should before retracting.

I have a similar issue on my G6, the dealer said it was nothing to worry about.  I'm not sure I believe them but I also haven't done anything to fix it myself.  I've had the car for 4 years now I haven't had any issues other than a noise for a short time when I start it and it's cold out, so who knows.

It was -4 last night when I left work, global warming I'm all for it!

Good to know, thanks sol. Hopefully that was our coldest night here.

Naturally out of my own carelessness I flooded the engine on my rx8 last night, looks like I'll be taking the sky to work until the next warm front!

Our cars make a horrible noise from the power steering pump also when it's really cold out.  You're sure it's the starter?

My Jeep started a little wonkey this AM, windchill showed -15 below.  Tonights predicted to be -20 wind chill.  I plan on putting the charger on tonight just to be safe.

I suppose it may not be the starter but it seems like it is coming from the trans tunnel and sure sounds like the gears grinding together. I'll see if I can get a video of it tomorrow morning.

If it only happens when its lower than 18* its the power steering pump.  GM has a TSB out on the issue and they put in a low temp power steeering fluid that pretty much eliminates the noise.  Dealer did this to my vehilce years ago and it worked but then my car was involved in a front end accident and they put the original fluid in and just never had it changed out to the low temp stuff.  At first I thought it was the Turbo since it sounds like a turbo with a bad bearing in it but its not.  Sounds like a shop vac that you plug the hose a horrible loud sound.

This sounds more like a blender, but it is at start and below 18*F almost exactly. doibg some more research it does fit the bill from all the descriptions online. Good to know I'm not the only one who is experiencing this...it's a hell of a noise though, others report no wear but I'm not so optimistic. Anyways thanks for the help guys!

Blender is more like it your right!!!!  and its an accurate as a thermometer will not do it on my car until 17*-18* or below.  Funny during the winter I actually use it like a thermometer in that if it makes the noise I know its lower than 17* LOL.

Tazz, I didn't know about the TSB.  Do you have the fluid part number or TSB to post.  I need to do this to both of my Solstices

Here's the video I took this morning. It was a toasty 23*F so I'm surprised it did it...you can hear it though is much shorter than usual. It was about 12*F when I went to bed last night so the fluid may still have been colder than the air temp.

Yeah, that's not the starter.  ^^ What tazz said (mine does this too).

Mine did that for the first time (or at least first time I ever noticed) yesterday afternoon when I left from work... timely post.  I wonder if low temp PS fluid is less of a good idea for those of us who autocross in the summertime...

GM cold climate power steering fluid #12345867

Subject: Whine or Growl Noise from Power Steering Pump (Change Power Steering Fluid to Cold Climate Power Steering Fluid)

Models: 2006-2009 Pontiac Solstice
2007-2009 Saturn SKY
2007-2009 Opel GT

Condition
Some customers may comment about a whine or growl noise from the engine compartment for a few seconds after starting their vehicle at low ambient temperatures (approximately -12C (10F) and lower).

Cause
In cold ambient temperatures, the power steering fluid thickens. The thickened oil may cause the pump to be noisy during cold start-up.

Correction
Important: DO NOT replace the power steering pump for this concern.

Change the power steering fluid to cold climate power steering fluid. Refer to Power Steering System Flushing and Power Steering System Bleeding in SI.

Parts Information
Part Number / Description / Qty

Wonder if its a Synthetic or blend of some sort so it can flow at lower temps.

I am curious if heat (90+) weather affects the winter blend.

Wisconsin gets bitterly cold, especially with windchills, but summer can bring very hot temps as well.
Generally I don't have an issue as I keep mine in the garage overnight, but the other day with windchills hitting -45 (parked at work) the pump screamed louder than it ever had.
Just here to help a friend! :thumbs:

Mine doesn't sound like that, but it does like to sound like a diesel engine when it starts up when it's very cold.

Speaking of...I should probably start the car since it's been "cold" out and I haven't started it in a few weeks.
