If the temperature gauge is reading low, you may need a new thermostat.
Replace it. Costs less than $20. You need the engine to be at working temperature before you'll get any heat. 1976VetteGuy wrote: > On Nov 26, 10:15 pm, Just another guy > wrote: >> What's the temperature gauge read? >> >> 1976VetteGuy wrote: >> > Group - I just bought my first Corvette -1976.

Well it may be as simple as manual heater control valve that's in line on the heater hoses. You turn it off in the summer and on in the winter. Whomever designed the nice heater setup on the 70's GM products needs to go back to school, I'm sure that person is most likely not around any more. My 78 Z28 pumped hot air into the car in the summer when the A/c was not on. I finally got tired of that and installed the above referenced manual heater control valve. I don't believe that the camaros or corvettes had a vaccum or other type heater control valve on the heater hoses during the late 70's. (1) check to see that the heater hoses are connected to the firewall, there are two. (2) check coolant level to make sure car is full. (3) let engine run and get to operating temperature (what is that temp?) (4) check to see if both heater hoses at the fire wall are hot...after engine runs a while. (5) check to see if previous owner installed a manual heater control valve or "by-passed" the heater core. (6) if all good above....then look for issues with the A/C -heater control head, broken cables, broken temp door, etc. I'm not sure on that model but it may have vaccum operated heater and A/C temp door controls, or it may be the old school pure manual setup. You have to "have" hot coolant at the heater core....for heat, that's the first thing to verify.

I actually don't even know where the heater core is located...I assume it's behind the firewall??? So if you have the time, can you get more detailed and tell me how to check this as I have replaced the thermostat and made sure it has enough coolant. I'm pretty sure it either a hose or heater core problem of some sort. I wouldn't know what the bypass would look like. I can't even find the damn water pump. I bout a new one, but my future father-in-law says that I would know if it was bad as it would be noisy and the car would overheat. So I need to find that so I can follow the hoses to the heater core? The guy at Autozone said that I should try to clean/flush out the cooling system...to try to clean out any gunk or rust that may be in there???? I bought a kit and a solvent to flush it with, but don't want to go throughg the trouble if I don't have to....???? It would be a cheap fix if it worked... Is the heater core hard to get to??? Thanks for your help... |

The heater coil fits through the firewall. The first step in the repair manual is to remove the seats, dash, and everything over the interior part of the heater coil. The second step involves removing the parts in the way under the hood. A good mechanic will charge about $500-700 for the day it will take to replace it. Start by finding a repair manual for your 1976. David |

I have both the 1982 Shop Manual and Chilton's. They do leave much to be desired. My mechanic subscribes to the Mitchell Repair Manuals as well as many others. Perhaps Mitchell has a limited distribution you could buy. I'd suggest finding a local mechanic (Master Auto Technician) and asking him/her. They will likely help describe the process or let you look at manuals. My mechanic would let you do it yourself, off hours, with his tools for a pittance. David |

The GM shop manuals are the best. A 76 corvette would be for the most part basic stuff, but everyone has to start somewhere. A GM shop manual is a good investment. You might hunt around E-Bay too. I would not waste my money on a CHILTON or Haynes unless that's the only thing you can get. ----------- Elbert |
