I have a 2005 Chevy Impala with the series 2 3800/3.8 and it is leaking coolant bad. It has been sitting for a few days as I haven’t bought and replaced the water pump yet. There is a large puddle of coolant on the ground right in front the right front tire. It has been leaking daily. I checked the lower hose and that is dry and in good condition.
My question would the water pump be leaking that much coolant while park. I never seen one just leaking this much or for that matter at all when the water pump went out. If the seal was shot you would think you would see it pouring out of the water pump but that isn’t the case.
I also have checked the heater hose elbow, which are usually plastic and can crack. However they must of changed it to the aluminum elbow. No coolant in the oil, it isn’t milky or sweet smell.
Any thoughts. Could it be a crack in the engine block? Coolant plug? Or just the water pump.
