If its the 3.1L it could be your intake manifold gasket , the material used for the gasket does not react well with GM's Dex-Cool antifreeze. The leak may not be apparent at first, but I would pressure test the cooling system. If you look at the front of the motor by the belts , try to peek down at the intake manifold and check for slight seapage to an obvious leak.

If its either of the Quad-4's they were notorious for heads warping or cracking.

SOURCE: coolent leak on fire wall in engine compartment on pasnger side

Hi , if you lift up your passenger side floor carpet and check underneath if there any coolant. If it`s dry you know the leak is in the engine bay ,if it`s wet could be either inside or outside of the firewall. In the engine bay check the hose clamps on both side of the hose if you can tight them or if one a those spring clamps try to reposition them. If you have hose clamp right at the firewall then you can easily change the hoses otherwise you have to access it from under or worst case behind the dash. Hope that helps.

SOURCE: Coolant leak on a 1998 pontiac firebird v6

It's probably your water pump dripping down behind the harmonic balancer. Many GM water pumps have a hole in the top of them. When they start to go bad, they start to leak out of that hole. I guess it's GM's way of "letting you know" there is a problem. If your water pump would just seize, and no indication was there, so you knew, you could burn you engine up in 10 minutes of driving.

The evaporator drain is plugged with debris and filling up the heater case. Remove the 90 degree elbow and clear the drain hole at the case.(pencil or piece of wire) You will know that's it when it dumps out a half gallon on the floor. Be sure to reinstall the elbow to keep out rain/ road spray.

2006 pontiac grand prix smells antifreeze in car


Is there coolant leaking inside the car? Check the floor under the passenger side dashboard. If the carpet is wet your heater core is leaking.

If the floor is dry check the coolant elbows going from the block into the automatic belt tensioner. That's inside the engine compartment. They are notorious for leaking. You may not be able to see the leak because it drips onto the block and evaporates. That's what the smell may be.

Search google images for "3800 series 3 coolant elbow" to see the part I am talking about.

The only way to find a coolant leak is to pressurize the cooling system. You can rent a coolant pressure tester from an auto supply store. Pressurize the system and look for leaks. You may have a leaking water pump.

The elbows can be purchased from the dealer. The water pump you can get from an auto supplier. Might as well change the thermostat while you are doing the other repair. Drain the cooling system and refill with fresh dex coolant.

Make sure you bleed all of the air out of the system or the car will overheat.

07 Renault Laguna. sems to using alot of coolant. no signs of leakage or overheating


The loss of coolant I assume only happens when the engine is at running temperature and therefore when it us under pressure and also hot. These type of leaks can be hard to spot as the they can be very small and as the water emerges it evaporates immediately so there are no tell-tale drips or stains. My first checks would be the coolant reservoir cap and the drain **** on the radiator. Make sure that rubber seal on the cap is not cracked and is seating correctly, a light smear of silicone grease may help. With the drain **** on the radiator there is often a rubber sealing 'O' ring, make sure this has not cracked or become dislodged (can sometimes happen when draining coolant - I have done this myself and it took me quite a while to track down the resultant leak). Again a light smear with silicone grease on the 'o' ring can help with the sealing. If these two checks show no problem then have the coolant system pressure tested at a garage. This will simulate the kind of pressure that the coolant is under when the engine is at operating temperature but since it is still cold the leak will result in obvious drips. If no drips are obvious then remove the spark plugs one at a time and check their relative condition. If you have a gasket leak into a cylinder the relevant spark plug will often look cleaner than the others as it has been effectively 'steam cleaned' during combustion. Next check your oil cap and oil levels. It may happen that a leak at the cylinder head gasket allows coolant into the oil passage ways. A thick mayonnaise of oil emulsion on the inside of oil filler cap is one indication of a leak via the gasket. If you have a gasket leak then this requires the cylinder head to be removed and for a new gasket to be installed. Hope that all helps

Transmission fluid & radiator fluid keeps getting low. know approx. where leak is, drivers side front on inside of front tire. would a leak in radiator cause trans. fluid to leak also from radiator?...


Your transmission fluid runs to your cooling system to cool the transmission oil. So, in answer to your question, one of the two transmission lines (one in, bottom and one out, top) could be leaking from the cooling system.

Bring your vehicle in for a cooling system pressure check. Another thing to keep in mind when inspecting leaks is that where you see the leak may not necessarily be where the leak is from. While the leak will drip down, the wind from when you're driving will splatter the leak all over the under-carriage of your vehicle making it look like leaks are happening where they in fact, are not.

There is a light in the dashboard that says "check" with the shape of a little water tap. I don't know what it means.


With the engine cool, Check coolant level, or may be overheating. If coolant is low or severely low, fill it, keep cap off and start engine, allow it to run and continue to add antifreeze until level of coolant stops going down and replace cap. Fill the expansion (overfill) tank to the full cold level. Allow engine to reach operating temperature while observing the engine, radiator, and hoses for leak and look under car for drips. Also check for wet carpet inside at the front, usually on the passenger side (not sure exactly where heater core is in your Kia), so also check the drivers side. This will indicate a defective heater core, if the leak is bad. If the leak is only minor in a heater core you will notice a sweet smell inside and/or windows will steam up when you run the defrost. Also, if coolant is low check radiator cap, If you don't have to push down with slight-medium force to turn and remove it, it may be leaking there.
Hope this helps.

Heater takes to long to get hot and water is dripping form dashboaerd on passenger side i have a 2000 grand jeep cherokee


Sounds like one of two things are happening. Either the hose going to the heater core (on the engine side of the dash) is leaking causing coolant to spray into the passenger compartment or your heater core is leaking which is causing the dripping from the passenger side of the dash. This would also cause a loss of coolant in the engine which would cause the engine to overheat and not enough coolant to get to the heater core to supply heat to the passenger compartment. Check your coolant level (while engine is cold) and refill it with a 50/50 mix of coolant and water after you tighten the leaking hose or replace the heater core.Then start the engine and let it warm up to operating temperature. Again let it cool down and then top off the radiator with the 50/50 mix of coolant. Do not under any circumstances open the radiator cap while the engine is hot.

My daughter's 1997 Saturn is leaking coolant and overheating..


Coolant leaks can occur anywhere in the cooling system. Nine out of ten times, coolant leaks are easy to find because the coolant can be seen dripping, spraying, seeping or bubbling from the leaky component. So open the hood and visually inspect the engine and cooling system for any sign of liquid leaking from the engine, radiator or hoses. The color of the coolant may be green, orange or yellow depending on the type of antifreeze in the system. The most common places where coolant may be leaking are:Water pump. A bead shaft seal will allow coolant to dribble out of the vent hole just under the water pump pulley shaft. If the water pump is a two-piece unit with a backing plate, the gasket between the housing and back cover may be leaking. The gasket or o-ring that seals the pump to the engine front cover on cover-mounted water pumps can also leak coolant. Look for stains, discoloration or liquid coolant on the outside of the water pump or engine.Radiator. Radiators can develop leaks around upper or loser hose connections as a result of vibration. The seams where the core is mated to the end tanks is another place where leaks frequently develop, as is the area where the cooling tubes in the core are connected or soldered to the core headers. The core itself is also vulnerable to stone damage. But a major factor in many radiator leaks is internal corrosion that eats away from the inside out. That's why regular coolant flushes and replacing the antifreeze is so important.
oses. Cracks, pinholes or splits in a radiator hose or heater hose will leak coolant. A hose leak will usually send a stream of hot coolant spraying out of the hose. A corroded hose connection or a loose or damaged hose clamp may also allow coolant to leak from the end of a hose. Sometimes the leak may only occur once the hose gets hot and the pinhole or crack opens up. Freeze plugs (casting plugs or expansion plugs in the sides of the engine block and/or cylinder head). The flat steel plugs corroded from the inside out, and eventually eat through allowing coolant to leak from the engine. The plugs may be hard to see because they are behind the exhaust manifold, engine mount or other engine accessories. On V6 and V8 blocks, the plugs are most easily inspected from underneath the vehicle.
Heater Core. The heater core is located inside the heating ventilation and air conditioning (HVAC) unit under the dash. It is out of sight so you can�t see a leak directly. But if the heater core is leaking (or a hose connection to the heater core is leaking), coolant will be seeping out of the bottom of the HVAC unit and dripping on the carpet. Look for stains or wet spots on the bottom of the plastic HVAC case, or on the passenger side floor.
Intake Manifold gasket. The gasket that seals the intake manifold to the cylinder heads may leak and allow coolant to enter the intake port, crankcase or dribble down the outside of the engine. Some engines such as General Motors 3.1L and 3.4L V6 engines as well as 4.3L, 5.0L and 5.7L V8s are notorious for leaky intake manifold gaskets. The intake manifold gaskets on these engines are plastic and often fail at 30,000 to 80,000 miles. Other troublesome applications include the intake manifold gaskets on Buick 3800 V6 and Ford 4.0L V6 engines.
INTERNAL COOLANT LEAKS
There are the worst kind of coolant leaks for two reasons. One is that they are impossible to see because they are hidden inside the engine. The other is that internal coolant leaks can be very expensive to repair.
