Generally, when foam exists in the radiator, you have combustion gases entering the coolant system, and the cause may be a bad head gasket or a cracked cylinder head and in some cases may be an intake manifold gasket leak. If you open the radiator cap (make sure its not under pressure) smell the air near the radiator cap opening while the engine is running and if it smells like exhaust fumes then you have the problem as I first stated.

    In some instances, Low coolant level can create this problem also.

    Thx. I will check that, but in the meantime, I have driven the car for appr. 2 wks w/no ill effects. I will be emptying the coolant reservoir and refilling the coolant to the proper level(s). Thx again. Ed B.

My advices is flush your cooling system, why you ask/what is cause your problem of the foaming in your reservoir, someone might of mistakenly add washer fluid instead of antifreeze .Windshield fluid does foam up when it gets mixed up with other fluids. So flush your cooling system and reservoir out completely.then add a 50/50 mixture of water and antifreeze. just to let you know after time the foaming will stop and case no problem.

Why is my power steering reservoir loosing fluid, what would cause the fluid to be "foamy" on top, and what should I use to fill it with?

spray down pump and hoses with degreaser and wash off. After its dry, use recomended fluid to fill. Start engine and turn steering wheel all the way left, and all the way right a couple of times. This will blead the air from the system. Now shut off and check fluid. Make sure it is full. Now drive the car down the road and make turns, and drive it back and check fluid level. If its still foamy and not leaking fluid, your pump ma be bad.

I get a 2001 nissan frontier the problem s the water s Ben overfill to the reservoir I always fill in water into the radiator that's the problem of my truck

reservoirs are just that reservoirs. Once the radiator has been filled to the radiator cap and the cap is operational the heated expanded water will flow out to the reservoir . When the engine cools down the resultant low pressure in the radiator sucks open a valve in the radiator cap and sucks water back into the radiator the . If you have to always fill the radiator and it is blowing water out into the reservoir but not sucking it back then I would have the cap tested for operation or check for a leak in the cooling system or hose from the radiator to the reservoir.

Loses water from resevoir but not from radiator

So the level keeps dropping in the reservoir? If you have to keep adding coolant to the reservoir, the system is leaking or losing coolant somewhere. Have the system pressure tested to find the leak. Is the reservoir itself leaking? When the level gets low enough, first the reservoir will go dry, then the radiator level will start to drop.
Here's how the reservoir works: coolant is under pressure from the radiator cap seal. As coolant heats up from hot engine, it expands, and pressure forces the radiator cap seal up, coolant is forced into the reservoir-remember the hot mark on the reservoir? When car is shut off, coolant contracts, creating a vacuum in top of radiator. This vacuum works to suction coolant back from reservoir into the radiator, keeping the radiator topped up, and coolant should now be at the lower cold mark on the reservoir. It is a closed, sealed system. The only loss of coolant will be a very small amount of evaporation from the reservoir. If coolant level keeps dropping, there is a leak somewhere.

How to take the air out the power stering pump

It may sound awful but the best way to do it is to get a buddy and some extra power steering fluid. With the car running slowly rotate the steering wheel side to side. Have your buddy keep an eye on the reservoir to make sure it stays full. The air bubbles should come up into the reservoir and make it look foamy. Once the noise tops and the bubbles stop rising top off the reservoir and make sure it is to the full line and you should be good to go.

Oil in water reservoir

I would assume It is a head gasket leak, maybe a cracked head. If it is pinkish and or foamy and you have an automatic transmission it is an emergency situation not that a head gasket is any picnic. It probably means that the transmission cooler built into the radiator is leaking high pressure trans fluid into radiator and could also draw radiator fluid into transmission. The result is transmission fluid condition referred to as a strawberry "milk shake". I wouldn't say what you think it is but take it around to a lot of shops... a lot don't know what it looks like. You can do more to diagnose this yourself if you want to do the research. but both are serious and can't be driven this way.

Overheating. Cools when stopped, runs hot when driving. Already replaced the radiator, water pump, thermostat, reservoir, heater core. The fans kick on like they should. My next guess is the catalytic...

It can be a clogged converter. It can also be a blown head gasket if you are experiencing any of these symptoms. White smoke from the exhaust, overfull oil level, a white foamy substance on the underside of the oil fill cap, loss of coolant with no apparent leak, or air bubbles escaping from the radiator with the cap off engine running.

Air in power steering how to get it out

Did you replace any parts?. any way fill reservoir instal cap, start engine and turn steering whell from lock to lock, left and rigth until it stops, do it couple off times then recheck reservoir refill and repeat this until it does not need to add any more fluid, then let car idle until fluid is clear of air,(foamy) fill reservoir to max line by now noise must be gone.
Good luck

Losing coolant from the reservoir but cannot see any coolant leaking on drive. Fill reservior to MAX and within ~10miles, reservoir is drained. Refill while engine still hot and don't lose nearly as much...

my '01 Jetta had a similar problem. I could always smell coolant and the bottle was always low. I crawled under the car and there it was..a caked on mess of pink antifreeze. There is a plastic intersection 3 way valve where the coolant temp sensor resides. it has 2 bolts and a rubber o-ring. Because it is plastic, it cracks. it drips down onto areas which are really not visible from above and then sizzles and melts onto areas under the engine. The part was only about $25, took 30 min to install and my problem is now fixed. Air was getting into the system through the small crack in the valve further complicating the system operation.

After driving my 2001 dodge stratus it draws coolant out of the reserve tank and I smell coolant. I have changed the thermostat and hoses so far. What is up?

Do you see white smoke from the exhaust? If so you may have a blown head gasket especially if this engine has overheated. Check the oil level and if it is overfull and looks like a cup of coffee with creme in it, you have coolant in the oil. Remove the oil cap, and if you see a foamy broth under the cap that is another sign of an internal coolant leak. If you see none of this then you have a leak somewhere. Fill the reservoir and radiator with coolant. Park the car over a clean driveway. Start the engine and then let it sit and run until you see where the leak is coming from.

I have to replace my radiator water every couple days and it still overheats and i changed the thermostat and the problem is still there. and there is no apparent leaks that u can see. i dont know what to...

Check for leaks when the engine is still hot. The problem could be a hose, water pump, cracked radiator, leaky overflow reservoir, bad radiator cap, or any one of several other problems. Isolate the problem/leak if you can, then decide whether you can fix it yourself or not. Also check the engine oil. If it's foamy and high on the dipstick, you likely have a leaking head gasket. Any competent mechanic can run a pressure check on the cooling system and also check the head gasket.
