SOURCE: coolant leak on olds alero 2000
Engines are designed with frost plugs that are designed to blow out if the coolant jacket should become frozen. Look carefully using a light and a mirror (ladys compact works well) Following the block heater cord to the engine will help locate these plugs. You may find the block heater has blown loose as it is installed in one of the frost plug holes. Best of luck.

It could be a hose on top of the engine leaking back there. It could also be a freeze plug on the back of the engine. Its a round disk about 2-3" in diameter and is recessed about 3/8" into the block. Check those out and make sure all hoses are good and tight. Any hoses that are kind of puffed out above the clamp should be replaced

When the engine is cold,check the coolant level.
Make sure it's on max.
A coolant system should be flush every two years.
If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.
The DIY method is to drive you car onto a ramp or a steep hill.
Iet the engine cool off and top off the coolant tank.
Set MAX heat + MAX fan
Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,
Check coolant level and top off coolant when the engine cools down.
A shop will charge $75+ for this but using an air operated excavate tool!
A car with over 90K miles may experience linkage problem to the heater control valve.
The heater control valve (near the firewall) may be stick over time.
Open the hood and move the heater to max and min. Back and forth.
Clean and lube the linkage with WD-40 to free the heater control valve.
If it's a vacuum type heater control valve then cash for leaky vac. hoses.
Move the fan switch back and forth to re-new the electrical conductors.
Pass a vacuum over the control panel to prevent dust build up behind the console.

could be waterpump?
i was going to say rad fan,but if so heater would be hot.
lack of coolant will make heater core to blow cold,if engine heats up with full coolant,usually means poor or no circulation.
run engine with full coolant,at operating temp.with rad cap off and look in rad cap hole and see if there is movement of water inside rad.
[rad fan will not come on if water is not circulating through rad water pump?]
