How to replace coolant tank on Saturn SL2

Recently replaced the water pump, hoses, and radiator coolant tank cap. Now having major "bursts" of leaking antifreeze when driving for a short period of time. Thermostat needle not even to half way mark but notice good sized puddle of water when backing out of a drive way and a trail leading back to my engine pulled back further and another puddle had already accumulated. Pulled forward to curb to shut off engine and investigate and there was small amount of visible steam. Could also smell the antifreeze burning off on the engine. Let it sit for  few days and car pooled until I could look at it and did not have any evidence of a slow leak at all. Only leaks once it has been driven for a short while...I got it back to the apt. complex yesterday and only can place the leak at the coolant tank. It seems to have a top and bottom half and the seam inbetween these two parts of the tank has moisture around it which would fit with where I see it leaking down from there. The wheel well cover is spotted with the leak dripping down. 
How do you find a quality tank and replace it?

The antifreeze tank is held on by I believe two bolts on the side. It's pretty easy to remove,

Just unbolt, remove hose and do the reverse with your new one.

As far as a replacement, I'd junkyard or ebay one. Lot cheaper, quicker, and easier than trying to get an aftermarket one and modifying to fit.

What is causing antifreeze to come out overflow tank?

Could be a defective radiator cap, or a leaking head gasket.

Coolant leaks from front of engine compartment on 1989 Ford F-150

have a coolant pressure test done on the system and find the leaks. If it is an old radiator with plastic tanks then the tanks may be split (common) -check radiator hoses for splits and radiator cores for leaks. If the hose is enlarged past the clamp replace it as it is about to burst anyway check water pump and check all points where hoses are clamped onto aluminium housings as they corrode under the hoses.

If radiator is replace and there is still a water leak problem. What could it be?

Water pump, radiator hoses, coolant overflow tank could be cracked . Even the coolant tank cap. Check the cap to see if the gasket is intact. If it looks stretched and worn, get it replaced.

My 1993 sl2 saturn its over heating i already change termostat and replace anti freese they gave me the green one so i mix it with water bt it still over heating the fan works only when i put on the a/c...

It could be the water pump. To check this:
  • Make sure the engine is not hot and open up the radiator cap.
  • Turn on the car and let it idle with the cap off.
  • Allow the car to warm up.
  • When the engine is hot and it is getting close to overheating, look down into the radiator. The coolant should flow. (It should look like a little river is going past the radiator opening). If the coolant appears to be still then your water pump is bad.

Other possible problems:
  • Bad coolant temperature sensor.
  • Air bubble in the cooling system.

Have replaced all major cooling system parts on my 98 cavalier. Sensor, therostat, hoses, etc. Car does not overheat or leak, however, after motor quits running and car sits for 10 or 15 minutes it will...

have you replaced radiator cap with the proper pressure cap? if so you may have a head gasket letting some compression into cooling system building too much pressure so the cap is bleeding it off into resevoir

My MR2 is getting a lot of pressure built up in the cooling system. It pushes the overflow tank's water out through the overflow hose. i replaced the thermostat and i keep adding water into the radiator...

I just was reading this and had a few thoughts for you:

1. Is it possible the thermostat is installed backwards? That's an easy fix.
2. Is the radiator fan working?
3. If the pumping action from the water pump seems normal yet the engine still wants to heat up, it's possible that the radiator is clogged-up.
4. Worst case... If with the radiator cap off, the coolant literally blows out of the opening... and the engine has really heated up recently... you may have a blown head gasket. If you suspect this, have the oil drained for inspection of coolant in the oil and don't run the engine anymore. A major fix would be required.

Hope some of this helps you. Good luck!

2003 saturn ion adding antifreeze every 2 weeks cannot find leak

There should be a radiator cap as it controls what goes into the overfill tank. You might consider replacing it. If there are no leaks in the radiator or hoses, there are only 3 places the coolant can go (water pump leak, blown gasket, or out throught the radiator cap). Hope its the cap because that's the cheapest. Good luck!

I have been leaking coolant and I do not know where it is going.. when I stop the car and walk around to the front,I smell antifreeze but see nothing leaking,, I also had to put some of the old green...

check heater core lines seems like they are dripping and hitting the exhaust,but check all hoses ,no mixing orange antifreeze and green is not going to hurt your engine but the orange is longer lasting then the green mixing them changes that by a little.

Replaced water pump, alternator, radiator, crank sensor and no coolant leaks and car has antifreeze, but why is low coolant dashboard indicator light keep flashing on 97 saturn sl2

Inside the coolant reserve tank there is a sensor for coolant level.

Over time,this sensor can get stick.

Inspect the coolant reserve tank for crack or leak.

Locate the coolant level switch/sensor and soak it in clean warm water.

Make sure it's free to move up and down the float path.

Top off the coolant tank with coolant only.
