Inspect hoses and generally cooling system after you have warm up engine at operation temperature and stopped. See if steam somewhere comes out .
If cooling system doesnt leaks outside, perhaps engine head gasket is broken. to have an estimate watch if your exhaust is leaking some water or steam when starting engine.

Is there a manifold gasket that prevents antifreeze leaks or could it be the radiator that is leaking

My 98 grand marquis keeps overheating i have changed mt intake manifold,thermostat and radiator my car will overheat to the fullest and then all my antifreeze will leak out


Hello, By doing RR most of this doesn't work. What you really is a auto technician to run some test on you car. The one test they really need to do is a pressure test on the coolant system on this Mercury GM. This pressure test will indicate if there is a leak down. That is, coolant is leaking. With coolant leaking a a closed pressurized system isn't best thing for these modern vehicles.


The coolant system is a closed system and the manufactures designed the system to hold pressure above 240 degrees. By raising the boiling point by pressurize coolant system.
This helps pollution system to operate more efficiently. GB...stewbison

You should look under the car after it sits a while and see if there is antifreeze on the ground. If so try to see where it could be leaking under the hood directly over the puddle. You could have a leaking water pump. If so there would be dampness under the right side of engine compartment. Also check the radiator hoses at front of car.

I have a 2006 dodge grand caravan that is leaking either power steering or antifreeze. The power steering is full but there was redish orange liquid leaking. The antifreeze is low and a horrible smell...


The horrible smell is antifreeze leaking from the heater core. This is the more serious of two leaks. You might be able to fix it with some stop leak. You can also tighten the power steering hoses.

Leaking antifreeze, doesn't run hot, took off hoses thought it was the top hose and can't see anything wrong with it. Can't see any cracks in radiatior any ideas?


You state you checked the top hose, did you check the bottom hose as well? Also, there is the possibility it could be leaking at the water pump.

2005 Jeep Grand Cherokee has antifreeze leaking


fill it up and wait for it to leak again. Its about the only way your going to find it for sure. Rev it up and let it get hot in the driveway.

Leaking antifreeze


first, remember that any leak will run down...There is nothing near your muffler that contains antifreeze, therefore, what ever is leaking has been blown back there while driving. Open up the hood and look to see where leak is originating. check all hoses, hose connections, radiator, rug under heater in the cab and everything associated with cooling system. You will see antifreeze coming out somewhere. Once you locate the leak, I can help you deal with it. Do not open the radiator when engine is hot! Do not drive with low coolant condition! This is not a solution...yet...I'ts the beginning of one!

Leaking antifreeze


could quite possibly be the water pump. There is a weep hole under the shaft, when the bearings go, the antifreeze leaks out at that point. Try checking w/ motor off using a small mirror to get a look under the water pump. If u see corrosion, or it's wet, get a new pump installed. Let me know what u find. good luck countrycurt0
