I can't tell you where your leak is because I can't see your engine...You need to take a very careful look at everything...every hose, hose connection, parting line between heads and block, between thermostat housing and engine and even at the water pump (you may not have gotten all of the old gasket off). If a good visual inspection shows nothing, you can pressure test the system and do a cylinder leakdown test and a hydrocarbon test at radiator to eliminate internal problems. Last but not least, you can have a dye test done (dye added to cooling system, leaks checked with a black light). Can the housing gasket leak? yes...but you need to check everything to determine if it is.

Any fluid leak can be hard to locate even if you have the vehicle in the air.

Assuming you mean you have just changed into a new water pump, and assuming the new water pump has the correct gasket and sealant applied correctly, and that the new water pump is not defective from the factory.....I'd say start examining the radiator for very-very small pin holes (not easily seen many times) also check your hoses for the same problem.

Other then that, if you had a reputable garage replace the water pump, take it back to them and tell them the new problem started after they worked on it. Could be they didn't do a good job from the start.

Without seeing yoru car, knowing what it is, it's rather difficult to hellp you find the leak, I wish I had more too tell you.

Hope this helped at least some.

OVERHEATING


Water pump or thermostat .

Jun 11, 2016 | Cars & Trucks

1 Answer

Coolant is evaporating, & there's no leaks


If you are losing coolant in a modern automobile at any significant rate of loss, then there most certainly IS a leak. The most common source of undetected leakage is from a worn out water pump. Many newer cars have their water pump concealed in the area of the timing belt. Here the coolant leaks out and evaporates on the engine block before there is any ability to visually detect it. Even older cars that have external pumps have "weep holes" under the drive pulley to provide early detection of impeding failure. Often, however, these leaks also evaporate on the engine before detection as many of these pumps are hidden well behind and under other components. Water pumps also have the "magic" ability to not leak when the engine stops rotating, even while there is still pressure in the cooling system, so you rarely get any coolant puddling under the vehicle to give away the problem. If the vehicle has more than 70K miles and has never had the water pump replaced, that is probably the first thing I would check out.

Overheating leaking


The overheating probably came from the coolant being too low. The coolant in the reservoir won't go back into the radiator if the coolant in the radiator is too low. Until you get it fixed, check and fill up the radiator every time you want to use it. Overheating is very bad for engines and can cause expensive engine repairs.
Where is it leaking, from the engine or the radiator? You didn't say, but wherever it is leaking is the place to start. If at the radiator, and it is not a loose or leaking hose, I would be looking for a new radiator. If it is leaking at the front of the engine and dripping down from there, you could have a bad water pump. This could be an expensive repair at a shop-not the pump itself-they are not too expensive-but the labor cost in replacing a water pump will add up.

The thermostat would not cause it to leak. But when all is said and done, you will want a new thermostat, after the leak is fixed. They are very cheap and it is just good insurance.

your leak is likely in head leaking into the spark plug ignition area and burning of once vehicle is running check plugs for moisture before motor is hot, also can seal using blue rhino at auto zone I used on 6 vehicles and sealed all of them.

Having over heating problems with my 2000 taurus it does it most with def. or air cond. on full blast did find small leak at water pump where it bolts to block. replaced both cooling fansand,the thermostat...


No!!!!...Yes!!!
No, the sending unit is working right.
Ideas? Yes, I think the problem is the water pump. Don't drive it overheated till you get a new water pump or have it inspected. You say it's a small leak where it bolts to block, but maybe it's the "weep hole" on bottom of pump leaking, meaning the internal seals on the pump have failed. If so, it won't be a small leak, it will leak all the time engine is running. A lot may be swept away by air, or by evaporating. Check it out. That's a likely cause of overheating.

My s 430 has smoke coming from under hood after driving but not all the time temp gauage reads normal. I had oil and trans leaks sealed but it is still happening, what else could it be? Thanks


SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.

My 1996 ford thunderbird is overheating and when it does so , it leaks water and anitfreeze from under the car and from top


It could be a number of problems. If coolant is not leaking from the radiator or bad hose the water pump is the most likely culprit. There is a weephole that the water can leak out of and the only way to repair it is to replace the water pump. Good luck

Slowly overheats after about 8mi.radiator cool at that time ,water pump running(good belt,not leaking) hoses hot also keeps neediding coolant top off but no leaking under car.no water in oil or evident...


That's about the right amount of time for a thermostat to start opening. If the rad is cold and the engine is overheating then get the thermostat changed. It's likely sticking closed. This situation would also cause your coolant to boil in the head and evaporate the water out of the mixture. That's why you need to keep topping up. Hope this helps.

Overheating problems in a 2006 Pontiac Torrent


Another possible cause is your coolant sensor. if the sensor goes bad, it will drip coolant but won't notice it because it just seeps down the engine components. Most people don't even realize that there is such a sensor. it will send a faulty reading that its overheating when the coolant level is fine and when enough coolant does seep out it will still say its overheating because it is at that point. I would definitely look into checking your coolant sensor as the cause since it's so hard to even see that it is leaking and its super easy to take out and replace. hope that helps if you're still having problems
