SOURCE: Welsh plugs leaking

Not much you can do other than replace it.
We call them freeze plugs or expansion plugs in the US.

No as soon as i fill the reservoir it empties in twenty minutes


There is a good chance that there may be a rusted out freeze plug leaking in behind the manifold where you can't see so well. That would explain the dripping and quick loss of coolant.

1998 ford mustang 3.8l v6 leaking cookant from bottom of engine. Not sure where. Looks like it could be from the pan right under the engine


most probably from a rusted welsh plug in the block. Have the coolant system pressure tested and watch for the leak as it is probably running down from the welsh plug and collection at the sump flange.

Replace the corroded housing and you will have to replace the rusted welsh plug in the rear of the engine . If it is from inside the bell housing it means gear box out and fly wheel / flex plate off

My mb100 van 1997 model has water leak at the back rear engine.the radiator is ok and the water pump.is there a water hose or port at the rear side of the engine?what and where is the cause? thanks, ermee


You may have a leaking core or welsh plug. This is a large disk which is used to block off the holes left behind by the casting process during manufacture. They are easy to replace but difficult to access.. It may also be a leaking hose or even a cylinder head gasket but I would suspect a welsh plug first. Take the vehicle to your local garage and get them to pressure test the cooling system, this will show up the leak a lot easier..

Coolent leaking


i doubt very much wether the block is cracked it is more likely to either be a heater hose may be leaking or a welsh plugs ( little round dish shaped plug ) in the side of the block i would first check all the heater hoses and the look on the side of the motor for a possible welsh plug leak i'd say its hoses tho
