The 3800's also had other problems. And also Issues for those that are unaware.

Be aware that there are bleeder screws to bleed air out of the system when filling the coolant. With out properly bleeding the system the coolant can Vaporlock in the system causing overheating.

Also if it has been over heated you need to check for a blown head gasket. Smell the antifreeze, if it smells burnt you should be concerned. Next with the engine cold and the system properly bled, leave the radiator cap off and start the engine, if it bubbles constantly or bursts out of the open radiator cap, seek diagnosis at your local repair shop as they have the equipment to do so properly.

I also suggest using an Infrared Thermometer to check temperatures with. if the engine is at 230f and the upper hose is at 200f, and the lower hose is still cool you likely have a clogged radiator. If the upper hose is cool as well then you have a bad water pump or t-stat. if the upper hose slowly warms, and you start to get bubbles then it's likely a water pump with the fins eroded off by electrolysis (gotta change that coolant at regular intervals)

Also make sure the radiator fans turn on.

Water dripping out of bleed hole on the pump case, car runs hot even after a thermostat replacement. Water moves slowly thru radiator looking down into top tank with radiator cap removed and engine running. Low pitched grinding sound coming from the pump area.

I have a water leak. the hoses all seem good as does the "weep hole" on the water pump. The oil and trans fluid look normal and the car runs fine. The only thing I see is below the alternator...


Not all water pumps leak from the weep hole, if the water pump casket becomes worn then it will leak from behind the water pump. You can also have a leak coming from the thermastat housing. To find out exactly have a pressure test performed on your car.
