Re: 1992 Cadillac deville heater bypass
The easiest way to by-pass the heater core is to take off both hoses at the fire wall and use a piece of hard tubing to insert in both hoses and use hose clamps it's quick and easy and should get you by. make sure you top off the coolant and do this with engine cold.

Feel the 2 tubes at the firewall for the heater core. If they are not getting hot, the heater core needs to be flushed out or replaced. I had this problem with a 1990 Cadilac Deville, it was just a plugged up heater core.
Remember to install sealant after flushing out the system to prevent leaks.
i was surrounded by smoke in the inside of the car while i was driving the car started to overheat and antifreeze poured into the inside passeger side of my car is it the heater core and is it exspensive?
check fan fuses and relays. is the idiot light coming on . stop engin temp. if its coming on unplug it . its located behind the rear valve cover in the middle. if that isnt it replace temp sensor. located below the air breather.
If you are not the original owner, the previous owner may have bypassed the heater core. The heater core is like a small radiator that has hot water running through it from your motor. It is inside of your dash board, near your a/c and heater controls. That is how yur car gets hot air. The air runs through the heater core making it hot. Bypassing it is a cheap and quick fix for a leaking heater core. When they get a leak, they leak all inside the car down to the floor board. Check under the hood along the fire wall. If it is bypassed, you will see two hoses spliced together. One will be bigger that the other slightly. If this is your problem, you are more thatn likely need to replace your heater core
if your 83 deville is a coupe like mine then you can access the heater core from under the hood, not the interior of the car. take a look at the blower motor and you'll see that the plastic cover that it is mounted on comes out. under that large plastic cover you'll find the heater core. it takes a while to get all the little screws out, but it's more monotonous than difficult. you'll have to disconnect the blower cables, the temp. sensor and harness, and a few little ground wires and you're there. once you get to the core it's really self explanatory. undo the hoses, replace the core, clean out the piles of pine needles that have accumulated over the years, then put it all back together. if you have the core in hand, then you can replace it in 2 hours if you take your time. hope this helped. let me know if you have any troubles.
