01 Malibu 31 replaced thermostat no leaks anywhere except out of overflow did compression test on all cylinders all good and no oil in coolant and no coolant in oil but still overheats then cools?
In Chevy Malibu
Why would coolant leak from the overflow bottle?
Answer I have a 1996 Jimmy and recently replaced the thermostat. I know the raditor drain plug is not too far under the coolant recovery tank, if not that, you may simply have a hole in the tank. From what I've heard, I would use caution using stop leak products, but I am far from an expert..
The …question is--- is it leaking or just always low on fluid. A leak in the tank is possible but another possibility is the head gasket is allowing compustion pressure to get into the cooling system and blowing it out---check to see if there are bubbles inside the tank when the engine is running ---a sure sign the latter is happening..
Jeep recovery tanks often have cracks and leak where the hoses atttach. (MORE)
Why does creamy fluid overflow from the coolant box in a car although the engine still runs but loses oil rapidly?
Answer .
Oil or trans fluid is getting in the coolant system. Have it checked out now. You can ruin lots of things by driving it..
Replaced thermostat and radiator on 96 Camry 4-cylinder but now car is overheating and no heat when the car is overheating fans all work and now coolant is leaking from a tube What do you think?
Answer .
Your description sounds like the thermostat is faulty. If the thermostat is stuck closed, there will be no heat for the interior. New thermostat's are occasionally bad, it has happened to me. The coolant is leaking from what tube? \nYou can verify the thermostat operation, but unfortuna…tely you must remove it from the engine (but with your symptoms that is the most logical failure). Put it into room temperature water in a pot on the stove. Heat the water and check the temperature at which it opens. This is a near foolproof check, but some thermostats are hard to tell when they open. You might have to pull it out of the water (use care it will be hot) to observe the open condition. In general 180-190 degrees F will be the temperature (water boils at sea level at 212 F) at which the thing is nearly fully open. But that depends on your exact version. The temperature is stamped on some them. \nFor further advice read through the previous posts on overheating or thermostat replacement..

What could cause oil in your coolant overflow and radiator but no coolant in oil in a 91 Seville?
Answer .
COULD BE ATF LEAK TRANNY FLUID GETS COOLED BY RADIATOR MAYBE BAD RAD. CAR RUNNING HOT?.
91 Seville's use coolant tabs from factory, that can lead people to think they have engine problems. You should have your car a check by a mechanic who can use special tools to check for blown head g…askets or other problems. (MORE)
You have a 99 Chevy Malibu you had a coolant leak took it to Chevy garage they said they had to replace the timing cover gaskets you am still losing coolant have you been taken for a ride?
perhaps the leak is somewhere else. may be you have not been taken for a ride but your mechanic did not follow proper procedures to pinpoint the problem he was more interested in your money and not on finding your problem. you need to run your engine and then carefully not to injure your self take a… look and see for your self where the coolant is leaking from. my advise, start by looking at your hoses and look at where they connect to. look at the thermostat housing and the heater hoses. also around the engine block look at the freeze plugs.(they may rust and leak) also you got to watch the water pump on that perticular car, usually its the 3.1 motor that has alot of problems with the water pump and head gasket. my 98 Malibu kept loosing coolent without leaking any, that's when I knew it was the head gasket. (MORE)
Why would my Chevy Malibu leak all the oil out at once?
Answer .
Where is it leaking from? It could be as simple as a missing/loose oil plug or oil filter. Unfortunately it could also be a rear main seal. Some Chev v8's have an oil cooler line that connects near the oil filter. The "o-ring" in that connector often fails resulting in rapid oil loss.
87 Chevy truck always runs cool but you have to add coolant or water weekly there is some coffee colored oil on filler cap but oil in pan looks great and no leaks anywhere help going on for a month?
Answer .
The condition you describe indicates the existence of an internal leak in the head gasket which permits circulating coolent to enter one or more cylinders where it is vaporized and discharged along with the exhaust gases. This situation can only be remedied by replacing the head gasket…. (MORE)
Should you replace your engine if an internal coolant leak exist and there is evidence coolant in the oil on a 1999 Tahoe?
Answer .
IT's probably just a head gasket. A reputable shop can pull the heads and resurface them and put a new head gasket in place and the engine will be as good as new or at least as good as it was before this happened.
My 1994 camaro z28 overheats and leaks out coolant i already replaced the radiator and thermostat what could the problem be?
\n.
\n Cooling Systems \n.
\nNext step after this would be to replace the radiator pressure cap, check ALL hoses for deterioration and leaks, check the coolant resevior bottle for leaks, and all connections to it. Check the drain plug and make sure it's snug in the bottom of radiator. Also, …you may need a new water pump. Good Luck!\n.
\n.
\n poor circulation \n.
\n.
\nI agree about the water pump, even if it seems as if it is working it will give poor circulation and cause overheating when pressurized until the bearings finally go out completely. but check the pressure cap first it is the most obvious and cheapest option, if it is bad when the system builds pressure and heat it will allow coolant to pass freely into the reservoir, but not draw it back in.

Why does the coolant boils and overflows to the radiator reservoir leaving the radiator low in coolant thus will overheat replaced 2 radiator caps thermostat reservoir tank and hoses 93 Camry V6 LE?
Bad seal on coolant outlet. .
TO MAKE A LONG STORY SHORT I HAD THE SAME PROBLEM. I FOUND THAT THE COOLANT OUTLET CAP WAS NOT PROPERLY SEALING DUE TO CORROSION ON THE SEAT LIP OF THE OUTLET. THIS WAS CAUSING A WEEPING OF COOLANT TO THE RESERVOIR AND A LOSS OF PRESSURE REQUIRED TO PREVENT BOIL OVER…. MY CHEAP SOLUTION WAS TO CAP THE COOLANT LINE TO THE RESERVOIR. PROBLEM SOLVED..
If you replaced two caps then I doubt those caps are the problem...there is something else causing the pressure to be too great and thus flow out. You could have a bad head gasket, which allows the pressure from the combustion chamber to flow into the cooling circuit creating to great of pressure for the cap, and thus, flows out. Just capping that line cripples the functionality of your cooling system, it is designed to make use of the overflow tank, you shouldn't just disable it like that. IF your head gasket IS going out, the blocking the overflow tank will cause EXTREME pressure to build up, now your going to blow the radiator and your engine. Cheaper to fix the head gasket and keep the old radiator then replace a radiator and a head gasket. On a cold start, stand behind your car, someone starts the car, smell for coolant. When the car gets cold, the higher pressure in the cooling circuit could cause coolant to flow in the engine, so on a cold start, you may smell it. After it starts though, the coolant may not flow into the cylinders. Get a coolant tester kit to check for exhaust gases in your coolant, you can find them at your automotive stores. You may not see white smoke coming from the tail pipe after the car has warmed up because the coolant may not flowing into the engine combustion chamber while it is running...but you might see white smoke. I'm diagnosing my fiance's car right now with this same situation...new water pump, new radiator cap, etc etc...head gasket is the next possibility. (MORE)
What needs to worked on or changed when the coolant is leaking into the oil?
Answer .
\nYou have either a blown head gasket or a cracked head. Serious engine dame will occur if this is not repaired. Do not drive the vehicle in until it is repaired..
Answer .
If you have an oil cooler line in the radiator, it could be the radiator. Otherwise, it's probably a head gask…et. (MORE)
Would a faulty thermostat cause engine coolant to leak in a 1997 Chevy Malibu?
Coolant Leak Probably not. If you don't already know a thermostats job is to open up to allow coolant to flow throughout the engine once it has warmed up; and it's supposed to stay closed until the engine has warmed up. A stuck open thermostat will have an engine take forever to warm up as coolant …is constantly flowing from the start and a stuck closed thermostat will make your engine run really hot and possibly blow it. Usually, leaks signify that something is not sealing somewhere like it should be (other than A/C condensation) so try to locate the leak. Start with the hoses, check and squeeze for toughness, if it squeezes to softly your hoses are becoming weak. Then check the radiator, drain plugs, radiator unit, etc. Check the reservoir as well and all paths and lines of your cooling system. If your vehicle has over 60,000 miles you may want to consider a new water pump too. (MORE)
Why would my 2002 Chevy Malibu v6 have muddy clumps in the coolant tank when the car runs great and doesn't overheat and the oil looks clean and nothing appears to be leaking?
it could be that your head gasket is on its way out or you mixed two different kinds of antifreeze.look at your owners manual makesure you put in the right antifreeze/coolant.(yeah, there are different kinds)
Why Ford Fiesta 1998 coolant leak you have replaced the bottom radiator hose all through to internal heater the coolant resevoir is ok it seems to leak when the car is cooling down what else can it be?
Answer .
Pressure test cooling system to find leak.
Could be freeze plug, water pump, thermostat housing, bypass hoses etc.
Oil in the coolant?
Oil in the coolant is never good. Unless it was poured in the rad by mistake (flush the rad and replace the coolant), it means there is a serious leak in the engine that needs to be repaired immediately. The usual causes are: head gasket leak, warped/cracked head, intake gasket leak, warped/cracked …intake. More rarely, the engine block's water jacket may be cracked or rusted through, in which case the entire engine block must be replaced..
Have the problem diagnosed immediately, the longer the problem exists, the more damage is done and the more it will cost to fix. (MORE)

Would suggest checking the ignition timing as this can cause overheating if not set correctly
Coolant leak mixed with oil?
Generally, when you find anti-freeze in your oil, it is usually a bad head gasket. However, it can also be caused by a cracked head or a cracked engine block. Was the vehicle ever overheated or run low on coolant? You might try a little shade-tree mechanic trick and add "Bar's Leak" (pellets only, d…on't use the liquid form). Warm up the motor WITH THE RADIATOR CAP OFF, then break the pellets up so that you have some dust and some pieces the size of BB's or slightly larger. Put the whole package in the radiator, put the cap back on, then go for a half hour or longer drive. After a week or two of normal driving, change the oil and filter. Then start checking the oil dipstick for signs of coolant. If the oil still shows coolant, keep an eye on the radiator level. If it isn't loosing too much, just drive it..
Either bad head gasket, cracked block or head, or even tranny fluid coming through cooler. whatever you do it is a bad idea to add any form of stop leak to a cooling system due to the fact that it will not only plug a crack in the block or gasket but it will plug off your heater core depending on how much you use. Then you guessed it no heater and another expensive fix, and if it is coming throung tranny cooler you have three systems screwed up: cooling, trans, and heating. Have a mechanic fix the original problem and do not make any more expensive mistakes. (MORE)
Could the intake manifold gasket in a 4.2L V6 be the cause of all cylinders getting coolant in them you did a compression check and all was good Cant figure out how coolant is getting into all the c?
Sounds like the head gasket may be leaking to allow the coolant to get in the oil but it it still sealing well around the cylinders..
Yes, lower intake manifold gasket is probably leaking. Very common in 1997 and 1998 models. Good engine, just needs sealed up.
Where is coolant leak in 93 Olds Cutlass Supreme No puddles not in oil. Reservoir doesn't leak but empties out. Car is not overheating. I have heard of some cars forcing it out an overflow hose.?
I would venture a bet, that you have a Lower Intake Manifold Gasket that is blown. And the gasket is causing the coolant to enter the combustion area, and be blown out the exhaust. Come over and join www.w-body.com/forum and I am sure one of the members there can help you further in determining the …leak. (MORE)
How do you get oil out of coolant?
flush system and depending on how it got there you may want to look at either head gasket or intake gasket
What does it mean when a 97 Ford Taurus overheats coolant leaks and steams from the overflow tank and the coolant in the tank is the color of rusty water?
i had that problem....thermostat was stuck closed.jusr replace thermostat,like $5 It could be a thermostat, or a water pump, or any other component in the system. The key here though, is probably the color of the coolant. Rusty brown coolant indicates dirt or rust in the system, or that someone …added a sealer to the system. Either way it's a bad thing. Contaminated coolant loses its ability to transfer heat properly. In addition, the rust scaling or a "bar's leak" type product can plug up the thermostat or any other small passage ways and cause the overheating concern. I would verify the cooling fan comes on when the engine is hot then flush the system thoroughly and replace the thermostat. This may not fix the issue but it's an easy and inexpensive place to start and it will rule out the basics tomake it easier to diagnose any other problems. (MORE)
Your 1993 STS sHow is hot engine then coolant overheat the engine water pump thermostat radiator have all been replaced What is the problem the fans are working fine?
Check your cooling fans in front of the radiator. It could be a relay or fuse to your high speed fan motor..
Also, check your coolant temp sensor, antifreeze level, and or thermostat again.

I have a blown head gasket and coolant leaked into the oil. How can I remove coolant from engine oil?
you can't. time for a head job . this requires machining the heads, and looking for other damage.
Oil is in the coolant?
Then you more than likely have a cracked head or blown head gasket. Stop driving the vehicle and have it looked at by a professional.
How can coolant leak into your 1996 BMW 328i oil?
Most likely, your head gasket no longer seals properly. Coolant and oil normally circulate through separate channels in your engine. A faulty head gasket allows oil to pass into the coolant channels and vice versa. If your gasket is leaking, you will also have loss of compression in one or more cyli…nders and possibly white clouds of steam in your exhaust, from coolant getting into the cylinders. (MORE)
Why is my cadillac steaming from the coolant recovery tank I replaced the water pump thermostat and coolant recovery tank cap and is still steaming first steam then water and it starts to overheat?
Either the cap is bad, your tank is either cracked at the seam or it has a pin hole that you can't see and the coolant is vaporizing ( steam ).
How does coolant get into the oil?
There are a few ways this can occur. If there are no other symptoms it might just be a leak in the front cover (where water pump is bolted to engine). A blown cylinder head gasket, cracked head or engine block could also be the cause. These are usually (but not always) accompanied by other symptoms.… Such as little or no interior heat, white exhaust smoke (steam) ,and or air bubbles in the radiator recovery tank. (take CAUTION when looking in the recovery tank hot coolant can be sprayed out without warning). The engine will likely overheat as well, (temperature sending units and the thermostat can fail to operate properly if there is air (combustion gasses) in the coolant system. Engine coolant in the oil will destroy the crankshaft bearings. Have the coolant system pressure tested. (MORE)

Why would there be coolant leaking into the oil in a 1995 Gran am?
I'm assuming your grand am has a 3400 v6 which are known for intake and head gaskets leaking. so its possible that one of those gaskets are leaking so bad that coolant is leaking from intake/heads down onto your valvetrain and then down into your oil pan. more than likely its your intake gaskets lea…king.

Why is there a coolant leak into the oil in a Chrysler Sebring?
If you have the 2.7L, the water pump may have failed. It is inisde the engine, driven by the timing chain. On any engine that can also be caused by a failed headgasket.
If your water pump had been replaced on your 1998 Chevy Malibu but the coolant still leaks what can be the problem?
There is a service bulletin that I just found for 1997-1999 Chevy Malibu 2.4L which can be found by searching 00-06-02-009 DEC 00 service bulletin. Something about those models if they contain the letter T in the VIN number leaking small amounts from the weeping hole. Not sure if this is your issue …but seems to be the issue on my 1998 Malibu right now. Noticed a small puddle under the car and hasn't appeared since. Good luck! (MORE)

What would coolant leak into all cylinders?
Coolant leaking into any cylinder is a clear indication that the head gasket has blown.
Why would coolant leak into all cylinders on 4 cylinder engine?
Coolant leaking into any cylinder is a clear indication that the head gasket has blown. Especially being that your engine is an inline-4, there is only one head and only one gasket.
Why do you have oil in your coolant recovery tank but your 2003 Pontiac grand am still runs good?
Your radiator is probably leaking transmission fluid into your coolant. Trans cooler is built into the radiator. Replace the radiator.

Engine oil leaking into coolant water?
That is not good, at all. That could be a blown head gasket, or even a crack in your engine somewhere not visible. The only way to tell is to tear your engine down and find the problem. It would just be best to take it to a certified mechanic. To be sure it is coolant and oil, does your exhaust smok…e come out Light Blue? (MORE)
What if coolant leaked into oil and car now won't start?
You have a blown head gasket, cracked head, or both. The engine must be taken apart and head gasket & head possibly replaced. If you drove it in this condition for a long period of time you may have totally destroyed this engine and it will need a complete overhaul.
How do you fill coolant once it has all leaked out Leak was fixed?
put a coke box or crate under the belly pan so the front end of the sled is higher then the back end pour your coolant in until it wants to overflow..Start it up & run it the reason for the front being up higher is so all the coolant flows back into the heat exchangers & does not create an air lock.….Whilethe sled is running the coolant will drop due to the thermostat opening..At that point continue to fill up your system until back at the top again & watch it for another minute or 2 to make sure it does not go down again..If it does,add coolant..Be careful not to overheat your sled leaving it idle too long while doing this..Just remember to have someghing lifting up the bellypan so your skis are off the ground..Keep checking your coolant level before every start up..I always check mine before every ride..Even if I only stop for 15 mins :) (MORE)
Why coolant overflows from tank after thermostat replacement?
most likely is do to air being traped in coolant system after replacement . and the air is being purged out as the engine warms up to operating temp ..
How do you replace the coolant in the overflow tank?
You usually need to remove the tank to pour the old out or have asuction device to drain it out. ======= Just adding to the answer : I use a cheap plastic turkey baster that I bought at Wal*Mart ( it doesn't take as long as I thought it would )
