Problem Description and Possible Solution
The water pump and/or the plastic side tanks on the radiator may leak causing a loss of coolant. The engine may overheat due to coolant loss. Continued coolant loss after external leaks have been repaired could indicate a blown head gasket.

I am loosing coolant and I believe it is coming from the water pump.
I have not had any overheating problem yet.
The radiator leaks at driver side bottom.Around a nut shaped plug.
My car was parked and all my antifreeze leaked out
i replaced the radiator and water pump about a year ago.i recently replaced the resivour tank.car still runs hot at speeds over 65mph .temp is constantly up and down 196 to 245.i have to put antifreeze in at least once a day.
when i put water in the car still runs hot and all the antifreeze runs out under the bottom of the car. antifreeze runs out very fast
Losing antifreeze and finally replaced the water pump, thermostat, belt.
Problems with leaking coolant.
Cost to fix: $750 to $1000. The problem? Northstar engine!
The engine is nothing but junk!!
I changed out my water pump supposedly there is some sort of line slash whose that is suppose to push up against when I mount it back up well it's still leaking what's the problem and how do you fix it is this repairable
check cooling light cont to blink while driving
coolant leaks. haven't found the problem yet.
The crossovers began leaking coolant. When this happens the coolant may mix with dirt from the engine or ground and appear to be oil. Heritage Cadillac robbed me of $1,500 by replacing the head gasket, knowing the crossover gasket was defective. Eventually, Heritage Cadillac replaced the crossover and water pump for another $1,500, only to say my electronic shocks were going bad. It's been a year later and my shocks are fine.
That Heritage Caddillac of JONESBORO, GA. Go to PEP BOYS, they won't cheat, lie, and overprice you.
Coolant started leaking and then spraying onto inside of hood. Then car stared overheating and can't hold coolant. Now head gaskets are said to be bad.
Radiator has been replaced once already at 70000 miles. The leaks persist but are not severe, yet. Average is perhaps 1/2 gallon per month/200 miles of travel.
a slow leak of coolant was coming from the water pump. water pump was removed and replaced to solve problem.
Coolant leaks out immediately as I'm pouring it in
I bought the car and drove home (about 15 miles) and all the water leaked out and the car overheated (265 deg.) I parked it and have not driven it since. I need to buy a new radiator at a cost of $180 minimum.
runs for awhile then overheats
Still trying to fix this issue.
