Coolant leak coming from the center of the car, under the engine

Well, if the coolant is leakimg from the HVAC drain, then you need a heater core, no matter what. You really have to jack it up and look, but I can give you a couple of pointers......

1. The water pump is leaking. That happens a lot. The coolant is leaking near the front of the car, near the center, but ever so slightly towards the drivers side. You need a special tool to replace it and I think gm has an updated cover and gasket.

2. The water pump housing is leaking. The gaskets that seal it to the block are made of plastic and deteriorate often. The coolant will be leaking at the center of the car, maybe up by the water pump, or back between the engine and transmission.

3. The heater hoses. I have only seen this 2 time, but the metal pipes corrode along the fire wall.

4. You could need a radiator. I have seen the side tanks leak a few times.....


Just A couple of places to look, but you have to get under and look....

under pump there's a weep hole, located in center of pump below the shaft that the pulley is attached, if coolant is coming out of that hole, pump is bad. otherwise, gaskets between pump / engine are leaking.

It is likely the water pump is leaking and the coolant is running back under the engine. Put you finger under the bottom of the water pump near the front where the shaft comes out, if it comes back wet with coolant the pump is leaking.

The Jaguar XK8 has a coolant hose on the rear of the engine that is prone to leaking. The leak is typically on the right side, right above the catalytic converter. There is a quick disconnect fitting that has an o-ring in it. This O-ring fails with age, and the coolant leaks from the connector.

there is a hose that comes off the water pump that goes in under the intake manifold maybe check there first sorry but its the best i can think of at this point sorry i couldn't be of more help!

probably the water pump. front and center of the engine, the pulley that may or may not have the cooling fan attached. from under the truck a leaking water pump usually leaves some coolant residue on the timing cover and at the front of the oil pan where the wiring harness come across.

Check to see if the water is coming from the center of the front of the engine or if it is coming from one of the sides of the front of the engine. If it is from the side it is probably a busted hose and cheap and easy to fix. If it is coming from the center, locate the water pump and look at it from the underside there is a weep hole there and if it is leaking from that hole the water pump needs to be replaced.

My wife honda Accord 1996 have the same problem, it was the hose from the radiator to the engine leaking when the pressure goes up after a while. a new hose fixed the problem.

OK, 4.3 V6 ? Coolant leak is coming from under the oil fill cover ? , do you mean the oil fill tube ? Could be a bypass hose is leaking, or a manifold gasket is bad, need more info maybe, pics

Have you checked to see if a freeze plug came out of the engine?
