    MPG What Are You Getting In Your 81???

    I get about 12mpg in Atlanta traffic. A few less and Scott Miller could write a song about my car. "8 Miles Per Gallon" @ Grey Eagle, Asheville, NC 1.29.09 - YouTube

    Question: 1981 Corvette Alternator Test Problem

    The car was running when I checked the voltage. The battery light on the dash is on brightly and the dash volt meter is reading low (which is correct). I checked it once more after my post. The voltage on that connector is about 2 volts less than battery voltage, but way higher than the 2 to 4...

    Question: 1981 Corvette Alternator Test Problem

    I was testing my alternator today using the matrix in the shop manual. I'm pretty sure the alternator is shot- I was getting 8v (battery voltage only) at the BAT post- seems like I should get 12-14v. However, I continued the test and checked the voltage at the the #1 connector. The matrix says...

    Help! brakes still pull - new caliper

    I can't know for sure without looking at the car, but I'd guess that the other rubber hoses need replaced. You replaced the front driver's side hose, so that caliper is getting full pressure from the master cylinder. If the other hoses are flexing, that explains why they are not locking up...

    So my car is probably mostly done( except paint and bodywork)

    If it were me, I'd sell it. You can go out and find another for less than you'll spend to finish the one you have.

    Question: Where is the A/C low pressure cut off switch?

    Update I jumpered the low pressure switch's connector and the compressor did not engage. Then I checked the voltage through it with my multimeter. When I have the A/C on, there is less than one volt going through the wires to the compressor. It should be 12+. This sounded like a grounding...

    Question: Where is the A/C low pressure cut off switch?

    Thanks! I will check the pressure switch when I get today. If I short it and the clutch engages, then I either have low freon (and a leak) or a faulty pressure switch. If the clutch does not engage, then it is either wiring or the dash control. Right?

    Question: Where is the A/C low pressure cut off switch?

    The A/C on my '81 hasn't worked in a long while. The A/C clutch never engages. So yesterday, I checked the A/C clutch by running a wire from the battery to the positive terminal on the compressor. Bingo- clutch engaged. So now I suspect the switch in the dash, but I'd like to check the pressure...

    Help! power window on drivers side

    Ok. It sounds like you don't have a multimeter yourself, but that you took it to a shop who told you that the motor is fine but there is no current. If the passenger side works but the driver's side does not, then you know that the circuit breaker is fine. You also know that the circuitry common...

    Help! power window on drivers side

    The first thing to check is the current at the motor. Hook up a multimeter and see what it says.

    Good E4ME M/C Solenoid read!

    Good find, Peter. This should be stickied !

    T-top into a convertible

    Just a thought... In this economy, you could buy a C3 Convertible for less than the money it will cost to convert your 81 into one. Think about it. You spend the same amount of money and end up with two Corvettes instead of one. It's a no-brainer.

    Help Brakes Problem

    It sounds like multiple problems are at work. The first thing you need to do (regardless) is solve your steering system problems. Fix the leak, make sure the car is properly aligned (all four wheels), check tie rods, make sure your tires are all inflated to the correct psi. The car should track...

    1980 Corvette Front Dash Speakers:

    You may want to hunt down a reproduction glove box insert before cutting into the original. It seems like an easy to find part, but a quick search on mid america, zip, and wilcox came up empty.

    81 spark plugs

    Thanks. That is what I thought.

    1980 Corvette Front Dash Speakers:

    I don't see why you would want to use the 5.25. A good set of 4x6's will sound great, and it's at least worth it to try using 4x6s before cutting your dash. If you don't like the 4x6s you can always return them. I'm planning on replacing my stock dash speakers this month with a set of Polk...

    81 spark plugs

    Is there any real difference between the standard, platinum, and rapidfire plugs (other than price)?

    Question: How long should it take for the engine to warm up?

    That is a great post. Is there an example with pictures?
