Question about 1996 Pontiac Grand Am

1 Answer

Unknown liquid leak from right side of engine

My wife heard a pop or thump from the right side of the car/engine while driving ~35mph, but had no degraded engine performance. I noticed a 2ft wide wet spot below the right side of the engine the next day or so. I pulled the car back to see if the drip would continue. It was much less the next day. The spot completelly evaporated and there is no evidence of the spot, but had a oily consistancy when first found. I don't think its engine oil. Too fine of a grade. There is no evidence of this substance slinging up top of the engine. I drove the car and all seems fine. Only now at Idle the engine is loping at a lower RPM. Power steering is ok.
We had just gotten the EGR valve replaced due to the car failing emmisions. Emmisions passed after the work was done. The car has not even been driven 500 miles since the work.

    Thanks! The resivour is on the right side. I did pour in more antifreeze, but so far there is no leak. I will have to drive it to see if there is more leaking afterward.

    Not real familiar with the grand am, but was wondering if the radiator overflow tank is located on the right side. The overflow isn't pressurized like the cooling system but it allows the expansion of anti-freeze and water in the system to prevent excessive pressure and loss of coolant on really hot days. On cooler days or when the engine isn't warm the vacuum of the system will "draw" the excess fluid back into the system. If the liquid has been there for a while it may appear brown or possibly have a greenish color to it. The oily residue but having the ability to evaporate leads me to believe that the leak is engine coolant. If the overflow tank is there try pouring some water into it and see if leaks out the bottom. The pop she heard may have been the reservoir cracking.



    Good Luck

Be sure to inspect all hoses for any wear or cracks that may lead to any leaks. Keep in mind that the top return hose that pushes coolant into the top of the radiator may only have fluid in it when the vehicle is warm or if it is running. Let me know if you have any more questions.

Good Luck

Leaking fluid under dash in car on passenger side also has load thumping noise when steering car into turns on the right side


You dont mention the year, make or model of your vehicle but generally a fluid leak on the passenger side interior is a coolant leak possibly from a defective heater core.Does it have a sort of sweet smell like antifreeze ? Also check under the hood to see if your engine coolant is low.
