The 2001 and other years also had intake manifold gasket leak problems. The "red" antifreeze destroyed the gaskets and caused the leaks. Both engines and multiple years had the problem.

I would have thought that by now a 2001 would have already been repaired, but maybe not. The local Chevrolet dealer here put stop leak pellets in mine the 2nd time they worked on it under warranty after being told not to put stop leak in it and create the possibility of heating problems from a plugged cooling system. They did it anyway claiming the GM service bulletin forced them to do it that way???
My brother had a 2002 and it also had the same problem, his daughters Malibu had the same problem. This was a very common problem in both of the engines.

Have a coolant system pressure test done to check for the leak. Check directly under the water pump as there is a drain hole there for when the pump seal fails. The brown stuff may be rust from an engine on the point of overheating.

SOURCE: Thermostat on 2002 Chevy Impala

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

SOURCE: my 2002 chevy impala is leaking transmission fluid

The line could need to be tightened. Tighten it with a 1/2" line wrench.(I think thats the right size for your car) Then check the trans fluid level to be sure its at the right level.

SOURCE: Antifreeze is leaking from around my radiator cap

more than likely it is a bad radiator cap. the pressure seal is leaking on cap.

SOURCE: 2002 Chevy impala overheating.

If your radiator is clean inside and you water flows and circulates with the radiator cap then it is OK. The leak is probably coming from the intake area or the head gasket. You could try some BARS leak that you can get at your auto parts store and see if it seal the leak. You pour it into the radiator when it is cool. You may have to drain some coolant. There is a drain plug on the bottom of the radiator that twist in the wrong direction to open it. If it does not open don't force it. Try the other way. It should come undone. Wait until it is cool.

Coolant loss with no trace

Doesn't sound good at all. If the water is not running out on the ground on the floor, it can only be going into the engine or out the exhaust pipe. Have a look at the oil dipstick and see what level the oil is at. If you add water and the level increase, you know the water is going into the engine. If this happens, it turns the oil a milky white. Get it fixed fast before it destroys your engine. The other end of the car, check the exhaust pipe and see if water is coming out there. These faults indicate a cracked head, blown head gasket or blown water jacket. the last thing to check is if your car is an automatic with an oil cooler in the radiator, it could be filling the auto transmission with water... Another disastrous thing to happen... If there is any reddish coloured fluid in the radiator or if the transmission fluid has gone a milky brown colour, that could be the problem. Either way, hidden losses of coolant usually mean major repairs...

Doesn't sound like it ran hot enough or long enough to crack or warp the head. If there is a crack, the engine will continue to overheat. If a warped head, car would probably run rough, the affected cylinders would likely have little or no compression, there would be a noticeable miss, and overheating would continue.
Why the low coolant? It's a sealed system, so should never have to add coolant, other than a small loss from evaporation in the overflow tank. Monitor the level closely for the next few days. Note the level in the overflow tank to see if it drops over time. Leaks can be external anywhere in the coolant system-engine, radiator, hoses, heater core- or internal in the engine-head gasket failures can cause coolant in the cylinders (white smoke out the exhaust), or coolant in the oil (oil will have a milky brown look to it), or oil in the coolant (will see traces of oil in the radiator).
A couple of tests may be called for. A pressure test of the coolant system will check if the system holds pressure as it should-about 15 psi. If pressure does not hold, there is a leak somewhere. Water pumps usually leak through the weep hole when they fail. A radiator leak would show up when pressure is applied. If pressure does hold, check if you have a good radiator cap-the cap is what seals the system so pressure will maintain. Coolant under pressure raises it's boiling point by about 10 degrees, so is critical to keep the system under pressure.
If you suspect further problems-losing coolant or continued overheating-then have the chemical test done to check for exhaust gasses in the coolant. Basically a check if the head gasket is good, a simple test done at the radiator cap opening with a special fluid that changes color if hydrocarbons are present in the cooling system.
Or you could have a compression test of the cylinders to check the internal mechanical condition-not only tells you if head gasket is good, also tells you a lot about engine condition-even,. balanced, good compression in all cylinders translates into good power output-rings are good, valves are sealing good, all systems go.
The cooling system: water pump, thermostat, radiator, hoses, heater core and hoses, radiator cap, overflow tank, and the cooling fans and associated wiring. Make sure everything is working right and you'll be good to go.

I have a 2000 daewoo nubira... I think that the head gasket maybe shot, but there is nothing leaking into the oil or the exhaust. Where the antifreeze goes the water is going somewhere, but not sure where...

White stuff in the water is most likely oil. To test the head gasket, fill the radiator right up to the neck, leave the cap off. warm up the engine untill the top hose gets warm. Then look for bubbles in the radiator, keep it topped right up to the filler top. Continuous bubbles mean a faulty head gasket.
Antifreeze goes in the radiator.

My 04 jeep grand cherokee is smoking from the radiator. the radiator fan doesn't appear to be running. i've had to put more and more coolant in the resivior because it keeps going right through it...

well,probably needs radiator replaced,burning off fluid smoking problem?if not going out exhaust or in oil,have radiator checked-replaced,if fan not running check relay and fuses,might need fan replaced,if you overheat engine to bad you will blow head gaskets and this is costly.check your oil,see if gray and milky,if so blown head gasket and water-antifreeze in oil,if going out exhaust will be blown head gasket inbetween the cylinders,fix radiator and fan first,but check out to see where all fluid is going.

Heating has stoped working and there is a little water in the oil, think radiator may be leaking, does my car just need a new rad

water in the oil will turn the oil brown like mud,is that what you see? if so,then you have a blown head gasket,do not run motor if this is the case as the motor wiil spin a crank bearing or lock up.are you sure about the water in the oil? look for real brown oil just like mud with bubbles on the oil dipstick. if the heats stopped working it may be because the radiator's low on fluid. look in the radiator for low coolant,if you can't see the coolant when you remove the radiator cap,it's low. with engine cool,remove the radiator cap 1st then start the engine. do you see steam and fluid blowing up frome the radiator? if so,you have a blown head gasket in the motor. head gaskets can blow and leak water into the oil or oil into the radiator. or blow and leak into the exhaust sysytem and blow coolant out of the tail pipe. three different ways for a head gasket to blow. usually the head gasket only blows when the engine has been run really hot!!! hope this helps.thank you for choosing fixya .com

How do i put water for the radiator?

Does your car have a cap or a sealed unit? You don't want a sealed unit. You want to be able to check your water.Push down and Twist the cap off when cold, not hot, fill it up with coolant, 50/50 mix, and fill up the expansion tank. It says coolant on it. The car will balance itself out. Check the water in your battery while you are at it. It dries out too. Then check the brake fluid, power steering fluid, and oil. That should keep you busy next Saturday. Hope this helps.

I have mud like stuff in my radiator

Mud like stuff? You mean oil like stuff? Is it white and greasy looking? This is not good. Check your oil for water, sounds like you have a head gasket going. Look for steam out the exhaust after it warms up. Drip some oil off the dipstick onto the hot exhaust and see if it sizzles, (water) oil will just smoke. Keep an eye on the temp gauge. Don't let it overheat. And shut it down if it does. A radiator shop can tell you if you have lost compression. Hope this helps.

What would cause my 2002 zx2 to overheat ?

Faulty thermostat, failed water pump, inoperable radiator fan, low coolant due to leak, faulty radiator cap, leaking head gasket, low oil, major exhaust leak near front, exhaust blockage, or incorrect ignition timing. If there is crust around radiator cap, cap is leaking. How long does it take to overheat? If it runs smoothly when cool, and all fluids are at correct levels, you can rule our head gasket, radiator cap, and ignition timing. If it overheats very quickly and fluids are correct, it is probably thermostat or water pump. If it seems to do better at higher speeds, it is probably radiator fan. You can check this by allowing vehicle to run in Park with hood open. Monitor engine temp on dash. When it is at or slightly above normal running temp, radiator fan should come on. Also note exhaust sound. If it seems loud and overheats gradually, you may have a leak before the converter. If the exhaust sounds quiet, but exhaust manifold is getting extremely hot (may glow red), there is probably a blockage. There will also be OK starting and idle but poor acceleration if exhaust is partly blocked.

If you are losing fluid and you do not see it on the floor it is going either of two places. In the oil or out the tailpipe. The fluctuations you see and the fan going on and off is the result of low fluid levels. Sometimes the sensors are touching the fluid and sometimes it is not. It sounds like the head gasket is bad. Check the oil filler cap and dipstick for white milky creamy stuff. If you see it the water is going into the oil and is destroying the lubricating properties of the oil and will destroy the motor if not taken care of. Change the oil very often until it is fixed. If there is no milky stuff it is likely leaking to the exhaust which is not as bad but still needs to be fixed. If you pressure test the radiator system it will likely loose pressure slowly if the gasket is bad.
