cash for clunkers trade ins get lethal injection

Three days before launch, the Department of Transportation has finally released the rules [PDF] for car dealers participating in the federal Cash for Clunkers program. Dealers must disable the trade-in’s engine [official powerplant-killing technique after the jump] and then send the clunker to an approved salvage auction or an authorized disposal company, which will kill, crush and destroy (not to mention recycle) the remaining bits. The doc also contains a word to the wise: “The CARS Act specifies that while many parts of the trade-in vehicle are permitted to be removed and sold, in the end the residual vehicle, including the engine block, must be crushed or shredded. Therefore, the trade-in value of the vehicle is not likely to exceed its scrap value. Purchasers should not expect to receive the same trade-in value as they might if the vehicle were to remain on the road.” I wonder how many consumers will make that calculation, or how many dealers will help them in that regard.

Engine Disablement Procedures for the CARS Program


Perform the following procedure to disable the vehicle engine.

1. Obtain solution of 40% sodium silicate/60% water. (The Sodium Silicate (SiO2/Na2O) must have a weight ratio of 3.0 or greater.)

2. Drain engine oil for environmentally appropriate disposal.

3. Install the oil drain plug.

4. Since the procedure is intended to render the engine inoperative, drive or move the vehicle to the desired area for disablement.

5. Pour enough solution in the engine through the oil fill for the oil pump to circulate the solution throughout the engine. Start by adding 2 quarts of the solution, which should be sufficient in most cases.

CAUTION: Wear goggles and gloves. Appropriate protective clothing should be worn to prevent silicate solution from coming into contact with the skin.

6. Replace the oil fill cap.

7. Start the engine.

8. Run engine at approximately 2000 rpm (for safety reasons do not operate at high rpm) until the engine stops. (Typically the engine will operate for 3 to 7 minutes. As the solution starts to affect engine operation, the operator will have to apply more throttle to keep the engine at 2000 rpm.)

9. Allow the engine to cool for at least 1 hour.

10. With the battery at full charge or with auxiliary power to provide the power of a fully

charged battery, attempt to start the engine.

11. If the engine will not operate at idle, the procedure is complete.

12. If the engine will operate at idle, repeat steps 7 through 11 until the engine will no

longer idle.

13. Attach a label to the engine that legibly states the following:

This engine is from a vehicle that is part of the Car Allowance Rebate System (CARS). It has significant internal damage caused by operating the engine with a sodium silicate solution (liquid glass) instead of oil.

    This Is a disgrace its watefull I went by my local dealership and saw a perfectly good gmc z71 extended cab pickup with a new sticker being destroyed I assaulted the tech performing this I am a mechanic run a shop and see people driving unsafe vehicals everyday that will NEVER take a LEGAL sticker I wanted to purchase this truck for my mother in law I have one identical that gets 24 mpg the reason most people dont get good mileage with thier vehicals is not the vehicals fault but more so operator error excessive speed impudent driving waiting till your 10 feet from a red light to stop from 75 ect. I will never drive a compact or sub compact again I had a civic and corolla and got what my full size z71 gets not what everyone else gets what i get. i get customers come in my shop complaing shakes over 80 the speed limit is only 65.... I think they are making vehicals and laws more to accomodate bad and even less competent drivers and It makes me sick to see nice vehicales destroyed when there are many on welfare getting state aide to keep some toilet running that WILL NEVER PASS A STATE INSPECTION.

  • William The Peugeot 308. I got to drive the last gen model on vacation to the SE Netherlands and I wanted to take it home. The new gen looks awesome. I want one bad.
  • TCowner Among my 25 year thus far Lincoln daily driver list of nearly all Town Cars, I took a dip into the PLC world with an 88 Mark VII LSC from 2006-2008. Beautiful handling car, comfortable seats, and oh that 5.0. I'd love to have one as a summer road trip car (I'll take a dark green '92 please) but had to get back to the big Town Car after some scares with the intricate ABS system and some other hard to find parts.
  • Analoggrotto I'd try to smash a can of tuna and some crackers with some fruit to avoid the sugar, cholesterol, refined starch and other crap in fast and packaged foods. Otherwise, Wendy's spicy chicken sandwich without mayo is good.
  • TheEndlessEnigma The tires are worth more than than rest of the car. IT's also a Michigan car, probably has unreported frame rust problems.
  • TheEndlessEnigma Fiesta ST, I have a 2016, I'd love to grab the newest spec 2023.
