1981 corvette still overheats with a new thermostat

Hello You will need to get a new ignition because I believe that one of the inside tumblers have fell Causing the key to be stuck .

1981 Corvette has an electical tachometer that is driven by impulses from the distributor. First, check for blown fuses, next make sure the tach wire is plugged into the distributor. Next bypass silver tach filter or capacitor located by manifold to see if the tach moves at all. If these steps do not reveal a change in tach operation, then the most obvious next step is to remove the tachometer and get a new board for the tachometer. Unscrew and remove cluster lens and then unscrew tach bezel, and gently pull out the tach noting position of insulators. I believe these boards are available still at local autoparts locations. Replace board, note position of insulators and reinstall tach, bezel and lens. Old corvette are cool and are pretty easy to work on! Should be fixed, enjoy!

You would get the correct carburetor instead for electronic computurized controlled carbs will not work on a 1981 Corvette

hmm..there might be a fuse box under the hood or most likely in the dash or under the passenger or the drivers dash..hope i solved your problem :)

you will need to pull off the four retaining nuts holding seat in place. Measure the length and width of bottom support frames. Many seats are interchangable.

See if you get power from the gray wire. Use a 12 volt bulb, or a multimeter.

Sure not a problem! I have a '76 Corvette. I use Mid America Motorworks. You may also want to search Ebay. I have purchased a lot of parts from both places, and have never been dissatisfied.

(I was a little skeptical about Ebay at first, but I dealt with those that have Ebay stores, checked their Seller rating, their Feedback score, and posted questions to them. Always got the part I wanted, and pretty darn fast!)

I bought my carpet set, and various steering components from Mid America Motorworks. They send me a catalog about two to three times a year. They have those T-Top gaskets sets for an '81 Corvette. Your Corvette is a C3 like mine.

The neutral safety switch is located in the shifter housing.

Here is a link to a good article on this topic, that would beat an explanation from me.
