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.

with the heater hose leaking and the engine missing I suspect an overheated engine from loss of coolant or pressure . It may be a blocked filter but I would expect a constant loss of power at rpm's.

Leak between engine and firewall


overheat = high chance for blown gaskets.
May be intake or head gasket, or worse, a cracked head or engine block.

Dry it all, fill it, start it, get a friend on the other side and start looking for the source of the leak.

Could be a freeze plug on the engine block. If you have a block heater installed in one of the freeze plug holes, check it for getting too loose and leaking. Pretty common problem with a block heater that's been in there a long time.

2000 Impala leaks coolant out hose in firewall


It sounds like you're looking at the heater core water lines. These connect to the heater core supply and return inlet and outlet pipes to bring hot coolant into the cabin for heat and windshield deicing.

The heater core is a mini radiator and operates on the exact same principles as the radiator does. The heater core is located behind the dash board on the passenger side. Look for a wet spot of antifreeze on the passenger side floor area - close to the firewall for an indication of a leaky heater core. If it is leaking, it will likely need to be replaced. This can be a pricey repair.

Good luck!

I had the same problem on a 2002 Alero V6. I found the coolant was leaking at the intake manifold on the left front of the engine. I tightened the intake bolts (which were very loose) and solved my coolant leak problem.

I have 2001 alero. Yesterday the coolant light came on and the engine just died. Any ideas maybe fuel pump or timing belt or could it be the water pump


IF LOW COOLANT LIGHT CAME ON ENGINE SHUT OFF BECAUSE IT GOT TOO HOT AND OVER HEATED.WHEN YOU HAVE LOW COOLANT.YOU COULD HAVE LEAKING RADIATOR.YOU COULD HAVE LEAKING RADIATOR HOSES AND WATER PUMP. ADD MORE COOLANT IN CAR RADIATOR UNTIL YOU AT FULL COLD MARK ON THE OVER FLOW COOLANT TANK START THE CAR LET IDLE UNTIL ENGINE GET OPERATING TEMPERATURE.RAISE YOUR HOOD LOOK FOR LEAKS THE RADIATOR PRESSURE WILL PUSH COOLANT OUT WHERE LEAKS COULD BE.LOOK AROUND RADIATOR AND COOLANT HOSES.LOOK AT WATER PUMP.IF YOU SEE COOLANT LEAKING AT WATER PUMP REPLACE IT.

Water pump leaking?


Water pump would be on the other end. There is a water housing bolted to that end of the head by the p/s pump. This housing is plastic and tends to crack. check it.

Sounds like the heater core (a small radiator of sorts under the dash) is leaking or a hose going to it is leaking. If in a warm climate, you could bypass or block the heater hoses temporarily. Their only purpose is to make heat avail to interior of car. The 2 heater hoses either connect to feedthru's at the firewall or simply pass thru the firewall to the heater core. Every car I've seen has it on passenger side.

Peer up under the dash, it should be clear where it's coming from.
