While this is obvious to most people who understand the workings of their cars, the quickest way to ruin your pump fluid and then your pump is to hold the steering on full lock when parking as all the fluid blows over the pressure relief. I am surprised how some people never get taught this basic rule for power steering. When I was buying a new battery years ago, the shop owner admired my Valiant as being a good old car. He told me of an old customer who had an (Australian) Chrysler by Chrysler sedan who swore by its reliability and comfort on long trips. The only thing that annoyed him was he had replaced his steering pump three times. The shop owner asked the customer if he ever held the steering on full lock. Surprised, he said yes - why not? He told him to stop doing that and he would never need to replace his pump again. I'm not suggesting this is the reason for this pump failure. Hey these things are 50 years old. Why are they still going is the real question, coming from an era of short warranty periods and new models every year. However, in my work as an engineer, I often hear how people think they need to modify a vehicle before finding out why it failed in the first place. Most of the time it is not due to poor original design. If it is, it usually appears early when the warranty claims start coming in and you will see a change in the next model. Those are the sort of upgrades I look for.

John, Contact Jeff Carter at JC Auto Restoration in Lynnwood, WA at 425-672-8324. Jeff can rebuild yours as good as new the first time out and will bench test it before shipping it back to you! He did mine in about one week turn around time and it has worked perfectly since he did it in June, 2005. I recommend that you install a power steering fluid cooler to prolong the life of the pump. We used a transmission cooler for a 2001 GMC 1500 series 4-wheel drive pick-up that mounted neatly to the front of the radiator yoke on the driver's side. We routed the hoses around the battery and through existing cut outs in the radiator yoke. After driving the car for prolonged periods with the engine nice and hot, one can hold the power steering cooler return hose and it is just liukewarm. So contact Jeff and he will take care of you superbly! 300'ly, ROB KERN ----- Original Message ----- From: John Skeggs To: Chrysler 300 Club Listverver Sent: Sunday, July 12, 2009 3:26 PM Subject: [Chrysler300] help, I can only drive my 300C in a straight line... because my power steering pump has quit on me. Any advice/sources re replacements or repair would be much appreciated. It is the later twin-pulley model, because the VIN is 2980.
