the hose from the radiator top to the reservoir has to be connected as this will be a hose that allows any air generated in the cooling system to be bled off and prevent air blockages in the engine

HOW TO CHANGE HEATER CORE IN 2000 BUICK CENTURU


Instructions
  1. Removing the Heater Core
    • Lift the hood and prop it open. Makes sure the engine is cold. Disconnect the negative battery cable with a socket wrench or box wrench. Avoid using open-end wrenches on the battery terminals, as they tend to strip the bolt heads.
    • 2Place a drain pan under the radiator. Open the radiator cap. Open the radiator drain on the bottom of the radiator and the two coolant drains near the oil pan. You can reuse the coolant unless it appears cloudy and contaminated. Close all three drain openings once all the coolant has drained from the system.
    • 3
    • Disconnect the inlet and outlet hoses of the heater core inside the engine compartment using a socket wrench. Be prepared to catch or wipe up any coolant that drips from these hoses. Drain the coolant from inside the heater core.
    • 4Unscrew and remove the lower instrument panel sound insulator from below the dashboard on the passenger side. Use a socket or screwdriver to loosen and remove the screws on the heater flooricon1.png outlet. Remove the clips and take out the duct.
    • 5Loosen and remove the screws holding the heater core cover in place. Remove the cover.
    • 6Remove the retaining bolts holding the heater core in place. Remove the heater core.
    Installing the Heater Core
    • 7Position the replacement heater core and secure the retaining bolts. Put the cover back on the heater core and reattach the screws and clips.
    • 8Reinstall the floor outlet duct with its screws and clips, followed by the lower instrument panel sound insulator.
    • 9Reconnect the inlet and outlet hoses to the heater core In the engine compartment.
    Refilling the Cooling System
    • 10Tighten all of the drains. Fill the radiator up to the base of the radiator neck with antifreeze, reusing the old coolant if it's cleanicon1.png. Fill the coolant overflow tank up to the "FILL" mark.
    • 11Reconnect the negative cable on the battery and start the engine, making sure you leave the radiator cap off. With the engine idling, look into the radiator and notice that the coolant level has dropped. Add coolant until the level is back up to the base of the radiator neck. Add coolant to the "FILL" mark on the overflow tank. Put the radiator cap on, making sure the arrow on it points to the overflow tank.
    • 12Squeeze the large return hose leading to the top of the radiator with the engine still running. The hose should begin to feel hot, indicating that the thermostat has opened and is functioning properly.
    • 13Check for leaks in the cooling system.

My 1989 GMC Sierra (350, 2WD) was leaking from the water pump and overheating...Installed new water pump and serpentine belt (after getting it off, it needed to be replaced)...Truck is still overheating,...


when replacing coolant, did you bleed the air from system! you can remove radiator or overflow cap when cold. start vehicle and let it run until thermostat opens,when all air is out hoses should get hot. but before starting, turn heater on to high setting, if you vehicle does not have a air bleeder on it. do as above. just be sure radiator is full of coolant. after hoses get hot, turn off heater, then put cap back on radiator or overflow. good-day! the first thing to do is to check for a stuck closed thermostat. do this first ok!

I need to change the coolant on my 04 GMC Sierra 2500HD diesel where is the drain point and where do I add the new coolant I do not see a radiator cap


There should be a petcock along the bottom of the rad. Most newer rads don't have a cap the antifreeze is added through the overflow tank.
