im with the stuck ign switch deal. Guys use to turn the keys to the start position on the hemi rams to cancel out the speed limiter. Scary thought knowing the abs and stuff is a mute point when doing 120.

 

Regarding the AC on defrost. The AC kicks on even on my 68 Chevy Impala. The AC on my sig truck doesnt run all of the time on defrost but it does cycle even below 0f.

 

On my Jeep, AC is on in Defrost. On our shop delivery Jetta TDI you need to press a button labeled AC or the window gets mighty foggy. Assumed the same on the CTD as you can hear the AC clutch slam home when the button is pushed. Even in defrost.

It's warmed up about 50 degrees so I've been unable to duplicate the problem. I'm thinking more about the power steering hint as the noise was definitely NOT a gear grind like starter to flywheel.

 

-34F this morning...and here we go again.

Was expecting it and shut off right away. Recycled the grid and fired again. Same heavy duty growl. Gritted my teeth and waited it out. Took longer this time. But it was waaay colder.

Would appreciate it if anyone knows the fix for this. Lightweight synthetic power steering fluid? BTW...the same effect with ABS/parking brake lights. Didn't drive it until 3 key on's/offs to clear the lights. Didn't think of the Smarty sitting in the house to read codes. Next time.

 

Flush the power steering fluid and fill with ATF+4 . Has been recommended by Dodge for severeal years now. You can either suck the fluid out of the resevoir with a turkey baster, or remove the return line to the pump and let it flow into a bucket while filling with fresh fluid until the return fluid looks the same as what yo uare putting in. The ATF+4 is basically a synthetic fluid with better cold flow properties, antifoaming agents and red dye , compared to power steering fluid.

 

Your jetta is most likely switching from recirculate to fresh air when you depress the a/c button.

Did you have the alternator/pulley belt chirp tsb performed on your truck?

Sounds to me that that you have an accessory bearing or idler pulley bearing ready to fail. Extreme cold deceases metal to metal tolerences and thickens greases used to lube the roller bearings in sealed assemblies. The best way to eliminate a drive accessory is to pull the serp belt off and start the truck cold to duplicate the problem, if no noise then move toward eliminating which accessory it is. If you have the same noise then on to plan "b".

Some excellent advice posted by all, hopefully we can help you get it worked out.

Good luck,

Tim

 

You could always use Amsoil synthetic ATF as it has a pour point of -63 below zero. BTW, Mopar ATF is what the factory put in my power steering pump and the same on my wifes 06 Sebring.

 

This is an 05 truck with 35k miles and contains whatever the factory put in the power steering fluid. I let it cold soak since Monday night and since it's +3 now, it will likely be -15 or so by tomorrow AM. Without starting, I'm going to check fluid and see if I have Jello in there or not. Then I'll get my wife to crank with me under the hood to see if I can spot the source of the sound. I'm betting Adaminak is on the right track. I'll use the Smarty JR to read the code after the ABS light comes on.

As for as Alternator/pulley belt chirp...no idea. I'll research the list again as I've not seen any TSB like that for an 05 truck.

 

Rod,

Next time you fire it up and the noise is there, try to turn the steering wheel just a little bit. I'm betting the noise will change and the wheel will feel unusually stiff.

As far as the belt chirp, I believe that only applies to automatic transmissions (more rotating mass), as my 99 chirped on every shut-down, but none of my manuals have.

-20F this morning...and best laid plans. The power steering pump was full of, well not quite full, bright red fluid that seemed like 20w oil in summer. No Jello. It was however, about 1/4" below the add when cold mark. -20F probably qualifies as cold. The truck started up fine -- no noise or lights. Guess I'll have to wait till the next cold front comes through. The belt is fine. Looks new. And this truck never, ever chirped. The pump output hoses run up under the master brake cylinder and that's right about where the sound comes from. They're definitely related. I'll add some ATF+4 to the pump today and wait til next time.

 

I believe you have it backwards..........the autos have less rotating mass, allowing the engine compression to stop the engine quicker, and the accessories can't slow down fast enough.

With the manual, you have that large flywheel (more rotating mass), and the engine can't decellerate as quickly. My manual only chirps a few times per year. The autos I've been around chirp at every shutdown.

My 05 did the same thing, change the power steering fluid several times with ATF+4 and it will go away
