If your cooling system has any bleed screws incorporated, crack them once in a while as well. 2000 Oldsmobile Bravada heater blows cold air. Had a new heater .

1. First you have to disconnect the Oldsmobile vehicle battery, then you have to drain the engine coolant into a clean container, most models don't have a drain plug on the bottom of the radiator, so you must take off the lower radiator hose to drain the system.

2. Second you have to remove the drain tube from the heater's housing and disconnect the heater hoses from the core, to reach out the heat core you have to take off the sound insulators on both sides of the car, then the steering column's opening filler and finally the air outlet duct and the floor air outlet.

3. Third you have to disconnect the heater core cover and then remove the core-to-housing mounting clamps and remove the heater core.

4. Fourth you have to Install the new heater core and connect the mountain clamps. I did a quick online search and if you need new Heater Core this site looks like it has cheap prices, free shipping and great reviews http://www.buyautoparts.com/heater_core.htm

5. Fifth Replace all the core cover,rear floor air outlet, air outlet duct, steering column opening filler, sound insulators and center console (if equipped). Reattach the heater hoses to the core and the drain tube to the housing and fill the cooling system, using new coolant if the old liquid doesn't appear clean. Be sure the lower radiator hose is securely back in place before filling the radiator. Reconnect the negative battery cable.

----------This will help.Thanks.

When the heater core leaks engine coolant, the sure way to fix it is to replace the core. It is a small raidator made much like the engine radiator. You can try radiator "Stop Leak". If it is a very small leak you may get lucky with the stop leak for a while. Sooner or later the core will need replacing.

Thanks for using FixYa.

Follow the top hose on your radiator back to the motor where it ends should be the thermostat housing.HOPE THIS HELPS!!!

THER IS NOT ONE

Remove and replace heater core, pre Mitchell labor guide is 5.9 hrs, does not include recover, evacuate and recharge a/c system, to remove heater core, that should be about another 1.4 hrs, hope this was very helpful.

It can come from any of the rubber hoses that link from engine to heater core or a non properly installed hose or the water pump.
