WATER PUMP VS HEAD GASKET

1998 Honda Civic

Engine Cooling problem
1998 Honda Civic 4 cyl Front Wheel Drive Automatic 140k miles

Just had my water pump replaced last month. After overheating again yesterday, found out we have a blown head gasket. Is the new (remanufactured) water pump at fault? Or could it be residual damage from the last failed water pump?

Hi superhawk996,

For this engine, when overheating occurs, it can damage the head gasket but is not noticeable in the beginning. The fault would become full blown only after some time, even up to almost a year before it becomes very bad.

I would believe the problem is from the initial failed water pump. After removal of the cylinder, if the rign around the cylinders are very dark or badly worn, that would indicate the problem had been there for some time.
