You must rock the engine foreward to remove the heater hoses. To do this you need to remove the bolts holding the torque struts to the engine. use a prybar and pull the engine foreward far enough to insert the long bolt you removed from the strut through the loop hole on the strut. This will hold the engine. Then you need to remove the sound insulators under the dash board. There is a black HVAC box under the dash, Look for the center floor vent outlet under the dash and remove it. Then You will be able to access a big square cover on the HVAC box. There is something like 8 screws that hold the cover to the box. Once the cover is removed You will find the heater core and the a/c evaporator (looks like a heater core but a little bigger). There is a plate that retains the heater core in the box. The plate is secured by a couple of bolts. remove those bolts, remove the plate, then remove the heater core. When installing new heater core, use petroleum jelly or some kind of grease like white lithium and apply it to the heater hose necks on the heater core to aide installation of heater hoses.
How do you change the heater core on a 1989 Oldsmobile Cutlass Ciera? or where can I get the Info on replaceing it

You can find the 1993 Oldsmobile Cutlass block heater on the right hand side of the engine block. You can follow the block heater cord directly to the block heater.
On a 1982 there are two doors, one in the heater outlet and another behind the glove box. May be the same for 1988.
take the 2 hoses off to the heater core and get a hose and flush out the core through both hose fittings on the firewall.
Take to a shop, there is about 25 or 30 blots to take out and not easy to get out
May be a defective thermostat or heater core
To do it correctly, get a manual ftom a parts store or AUTOBOOKSONLINE.COM. They have pictures and everything
Yes, if the blower isn't working. If it turns out to be the fuse, and it blows again, you probably have a bad blower motor.
It's on the firewall up high on the passenger side. You may need to remove the alternator to get it out.
At the firewall on the passenger side
Well i recently just replaced my 1989 Oldsmobile Cutlass Calais S 2 door Heater Core. Man is it a Job! You have to dismantle the center console including the parking brake and radio to get to the heater core. once you pull all the plastic/fake leather away its pretty easy.

You may want to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.
You can purchase a used shop manual for that vehicle. Check ebay for such a manual.
The heater core on a 1984 Cutlass Supreme is located under the blower motor on the passenger side of the car, under the hood. First you need to remove the blower, and the hoses connecting the heater core. Replace the core, re-attach the hoses, and put the blower motor back on.
Could be, low on coolant, stuck open thermostat, plugged heater core, temp blend door malfunction,
Might be a bad heater control
Either one of the heater hoses are leaking or you have a freeze plug on the side of the engine leaking.
Get it warm and feel both heater hose's at the firewall and see if both are warm. If not, the heater core is probably plugged.
An exploded view of the heater controls for a 1989 Olds Cutlass can be found in the Cutlass service manual. The manual can be found at most auto parts.
