  1. Well, you can rule out road force balance, wheel balance, tires, or rotors. 30 mph vibrations are from seriously out of round tires or bent wheels, both of which you've already ruled out...twice, or from other mechanical issues. I'd be looking at CV joints, bad bearings, or other suspension parts at this point. Even loose tire belts, normally not visible at standstill, don't begin to cause vibration until about 60 mph.
  2. What were the final numbers on the road force balance? Did they have to re-orient any tires on the rims to reduce the road force? What standard minimum road force did they use as a guide? If like most, and they used 15 pounds, it is likely that you will continue to feel that. Oh, and this vibration IS most noticeable from 68 to 72 mph, right?
  3. I have a leftover GATES (US/made in Mexico) Part Number K030245 Micro-V that is brand new, never used. Would gladly mail it to you for free if you PM your address to me. Looks like former part number may be 3PK625. This belt probably fits all years of Northstar production. I only have one, so first person gets it.
  4. Jan, Does anybody in the Cadillac Club over there need a water pump belt for a Northstar? I have a leftover GATES (US/made in Mexico) Part Number K030245 Micro-V that is brand new, never used. Would gladly mail it to you for free if you PM me.

    Looks like former part number may be 3PK625.

    I no longer need it since my purchase of a MB E350 4matic.

      I'm sure that the belt will come to good use. I suggest that you post in the Swedish sub-forum about it since I made a promise that I'll never make a post there again. I did not agree to the Cadillac Club Sweden way of doing things (they feel that it is their forum) and was also tired of the attitude of far to many posters there. For a couple of years I was the moderator over there and discovered that they are nothing like the helpful and eager to learn bunch found in the American forum...

      Sorry to hear that Jan. If you personally don't need the belt, I will offer it for free on the normal forum. As you note, just trying to be helpful.

      I don't have any use for it but I'm sure that your help will be appreciated!

  5. When were the fuel filter(s) last changed?
  6. Getting back to your question for a moment, the answer is no. Even though gas charged shocks do provide a little bit of lift, you may only expect to see about a 1/4" difference in ride height. Not nearly enough to replace the air shock or load leveler type of shock that is required.
  7. It works great on windshields Mike, as well as all glass surfaces. In fact, glass is the easiest place to tell just how well it's working since the stains are much more visible on tinted glass. As far as the CLR goes, it seems a bit harsh. Maybe not so much on the car's finish, but I don't like that stuff on my hands. It's also quite a bit more expensive. The vinegar is cheap and most people have a little bit laying around the house. I've never tried mixing it with the wash water, but that might be an option. Maybe even in one of those hose end sprayers for the final rinse would work
  8. Having lived in areas with very hard water, I can tell you that the marks left behind by the calcium deposits can be very annoying, especially on dark colored cars. I just learned an easy way to remove these spots before waxing. I used a pad of several layers of paper towel saturated with plain old white vinegar. It works like a breeze. I keep a terry towel with me and do about a panel at a time, wiping the vinegar off after letting it set for just a few seconds. After the wipe down, I either use a spray wax or a paste to make the car look like new again! Make sure the car is clean and cool to
  9. Don't know if your car had this option, but around 2006 (I know, much later) a recall was issued for the heated windshield wiper fluid heating tank. This recall was due to a smaller than needed printed circuit conductor inside the box, causing melting and possible fire. Recall fix was to cut the wires! My best guess though would be the blower motor or plug as Rockfangd suggested.
  10. What engine, and under which operating conditions is 20W-50 Mobil 1 even called for? Maybe a Porsch Turbo with 200,000 miles in, say, the Mohave Desert? Possibly racing engines? Just trying to learn here. I can tell you that the Mobil 1 0W-40 European Formula is called for year round in passenger car (V6) service. Complete with meeting fuel economy specs for those cars. My point is, sometimes you give up certain oil qualities for specific applications. Racing oil doesn't require much detergent, some diesel oils require more dispersents, Oils designed for higher mileage vehicles cont
  11. So my question should have been directed more at the writer of the WSJ article, who, like so many others do not understand the Volt and what it is capable of. It is also my opinion that GM's position is just fine, based on the engineering knowledge it has gained in the Volt, and the Bolt, it will be able to respond quickly if gasoline prices head towards $4.00 per gallon again. Further, I see absolutely nothing special about a purely electric car. I'd much rather use 9 or even 25 gallons of gas a year and totally eliminate range anxiety.
  12. I'm not sure I understand what you are saying when you say that GM has "bypassed the hybrid wave with just the Volt and the ELR". The Volt is a great car, and still gets the highest satisfaction ratings of all GM cars by owners. ELR was just a really BAD idea, with a really HIGH price. The Volt was designed for the person that drives back and forth to work every day, and plugs in at night. No, it is not a highway cruiser and was never intended to be, but it did a fine job on the nonstop trip from Ohio to Florida. Not any worse than driving a Cruze or a Corolla. Having owned one, it just
  13. Having owned a 2008 DTS since new, I can tell you the things that happened to me. The front brakes were replaced under warranty for causing a shudder when they got hot. Not much of an issue in Florida so the previous owner may not have had the work done. This is a known issue, not exactly a recall, but WILL be covered by Caddy. It will only appear when going down a steep hill or other long grade. Amother item was the ignition switch. It would not sense when the key was removed, therefore the EXIT position of the seats and steering wheel would not activate. Replaced under warranty. Speakin
  14. Back when it was Westley's Bleche White, it DID NOT have bleach in it. Now it is made by Black Magic, and doesn't work well at all. Prob. a liability/environmental/safety issue. Still doesn't have bleach in it. Lots of good tire cleaning products out there today. I like "Tuff Stuff" in a trigger spray and a Nylon bristle brush.
