Odd coolant leak

[ericsmith32]

Yesterday I did a full trans flush on the Aspire. As I was finishing I noticed a noticable coolant leak at the front of the engine. It was dripping from the very front edge of the oil plan. I'm assuming it's the water pump. What's odd is it's never leaked before. Even stranger it hasn't leaked since I pulled it off the ramps. I did have the hose to the excess reservior pinched though.. I wouldn't think that would cause it though. A leak that bad I would of had to add coolant even though I've only drove it a couple hundred miles so far. A engine front end overhaul is in order this summer. Thoughts?

could it be the bypass pipe that runs from the water pump to to the heater core?

[ericsmith32]

Didn't seem to be. I'd think that pipe would run back and drip farther back.

Core plug?

When the water pump went on my KL it only leaked when it was running and for a couple mins after I shut it off

I think the leak moved further down.. not for sure the work parking lot is really stained. It doesn't leak when it's running unless it's a higher rpm. I let it idle and it stopped, only after it's shut off for a period of time. Most likely it is something to do with the water pump. .. whether the o-ring to the steel pipe or the pump itself. Tempted just to replace the o-ring and see what it does!

There is a weep hole on the water pump and if it's leaking from there either a bearing failure or a leaking seal. The pump will need to be replaced. While that is being done it is also a good time to change hoses as the system will be partially drained.
