I have a 1992 Cadillac Sedan Deville. Was not getting any heat so we replaced the heater core, it was plugged bad. heat worked good for about one week. Then heat went away and water was dissapearing from the radiator.

Changed the water pump(it was leaking).new thermostat, radiator cap and new fluid. Still no heat, just cold air. Any other suggestions. Also the overflow tank is always full. My husband took some out because it was too full and then today it was full again.

Could it be a head gasket(someone suggested that) and would that make the heater not work? Car does not overheat and runs good. Also with the thermostat removed car has a little heat blowing out.
thanks,
Linda

Hi there Linda,

Did you read my article about heater cores? Read this first, especially the part about checking your radiator and heater hoses to make sure they are hot to the touch.

Car Heater Problems

If the old core was plugged up with rust, I would imagine the radiator is also plugged up and not allowing the hot antifreeze to circulate through out the engine. No hot antifreeze going through the two heater hoses at the core…..results in NO hot air coming out of the vents inside the car.

If you have two very hot heater hoses, then you most likely have a control problem inside the car…..stuck cable in the dash, or control head problem in the dash etc.

Blessings,

I have a 97′ cadillac catera that is making a hissing sound near the engine and there is steam coming from under hood near or from the engine. Also my anti-freeze is leaking profusely from under the car near the middle near the the tranny fluid resovir. Do you know what the problem maybe?

Hey there

Sounds like you have a coolant leak alright. If you don’t see the exact leak, I would suggest you get a “cooling system pressure test” to determine where the leak is coming from. It could be something as simple as a hole in a radiator or heater hose, or something more complex like a radiator or water pump leak.

DO NOT add any type of coolant sealer or stop leak…those products will NOT help in this situation and can make things worse. The coolant test is cheap and easy and just about any mechanic or fast lube place can do it for you while you wait. DO NOT let this engine overheat…it is very expensive!

Blessings,

The system will not shut off when hitting the “off” button on the dash. The Cadillac dealer here repaired it three years ago, but that repair lasted about a month.The car has been stored but I would like to get everything running smoothly…Can you figure out the air conditioner problem ??Thanks

Jim

Howdy Jim,

Personally I have not seen this exact issue before. I have seen “a/c blower resister modules” go bad and not allow the blower motor to shut off…..even with the engine off and key out the blower will continue to blow. I don’t THINK that is your problem here. You could just be low on Freon……since you said it blows hot air.

The system will shut it self down if it there is not enough compressor oil/Freon in the system to prevent damage. I would have your Freon level and pressure checked FIRST and fill with Freon as needed then I would read your onboard computer codes to see what “codes” have been stored in its memory.

These are complex systems and I would stick with the dealer or a mechanic who is qualified with Cadillac automatic temperature control systems….which will rule out most mechanics. Keep me posted as to what you find out will ya?

Blessings,

Austin Davis
