To replace the heater core in a 1987 to 1990 Chevy Celebrity:
1. Using a suitable container drain the coolant level to below the level of the heater core inlet.
2. Under the hood loosen the clamps and remove the inlet and outlet hoses from the heater core. Remove the insulation for use on the replacement heater core.
3. Remove the under dash panel.
4. Remove the heater plenum under the passenger side of the dash. Take note of the fasteners so you can put them back.
5. There is a small duct that covers the tubes that go thru the firewall. It is held on by three screws, one of which is nearly hidden. The duct may be stuck in place with sealant, be careful not to break it.
6. The heater core is held on with two strap clamps, remove the four screws and take the clamps off.
7. The heater core should now pull out of the firewall.
Reverse these instructions to install the new heater core.
After the replacement heater core is in place refill the radiator with coolant. Start the engine and check for leaks, repair any leaks. If the coolant is hot let it cool then check the coolant level and refill as necessary.
