k, i just recently got into restoring groovy old cars, and i've got a 76 coupe deville off of which the PO has torn the majority of vacuum lines,, it is astounding the thing even runs, (and it purrrrz), but it overheats like mad, obviously,, soo, what i need is a vacuum line routing diagram for this year and engine (500ci 4BL),,, i know theres already posts on this topic, but i also know the routing changed slightly year to year, and i dont wanna take any chances,,,,,
so if anyone could pleeaze help me it would be greatly appreciated,,
thanks in advance!
Did your car overheat before you changed the thermostat? Those year caddy thermostats have a piece at the bottom that fit in the block and if you use the wrong one it overheats..so make sure you have the right thermostat and some parts guy sold you the wrong one...
we havent started it yet to see if it'll overheat again,, we got the tstat at checker and they say its the right one for make model and year,, however, if u have a pic of that lil piece ur talkin about that would be cool,, just so i could be sure,,,
annnnnd, if u have a vacuum diagram, that would be STUPENDOUS,,,,
