hi everyone, 2001 s-type 3.0 approx 120,000
I need some help today while picking my kids up I started smelling antifreeze and noticed some smoke I pulled off to the gas station checked the resivoir and it was empty so I put in antifreeze and water let it cool for a bit and started driving again, the temp shot up so I pulled over again and noticed antifreeze coming out below the car (below resivoir area) its possible I overfilled. waited for the car to cool all the way and took a shot at getting home (3 kids, no family) I was able to get home with no problems temp stayed right in the middle, I checked the resivoir and there is a little antifreeze in the bottom (I know, I lost a lot).
-earlier in the day I noticed the fan on when I went into the store.
-car just had oil change and fluids checked 1 month ago
-the heat only works when its set to defrost highest temp and setting
I have a hunch that I need a new thermostat (that I can handle) my other concern is the antifreeze leak, if I did overfill is there a purge line? or did I blow a hose/gasket/the resivoir? any help would be appreciated.

thank you for your reply, and I think you are right. I just went out to the garage to tinker with it and when I added more antifreeze it started leaking out of the bottom again. I think I may replace both considering the thermostat doesn't cost much. other then this I love my car, although it is getting a little to small for the kids.

Reservoir is a well-established weak point. If yours is original you are way past-due for problems with it. I second Jagtastic.
If any of your kids have hit 10 or 12 yrs yet...assign the task...it's not too bad. Thermostat would stick open or closed. If open, you'd get the same temp heated air regardless of mode (assuming your DCCV is working properly) and not much, at that...and if stuck closed...you'd be overheating the engine after the first few minutes. Not sure about the older ones, but the 03 and sub reservoirs are fond of cracking up top at the overflow hose nipple.
Keep us posted what you find and welcome to the forum.

To save yourself both time and money, stick with replacing the overflow reservoir for now. If the vehicle is not overheating the thermostat is most likely still okay. The thermostat on the 3.0 litre engine is within a two-piece casting between two hoses and can prove difficult to change if the two 8mm bolts are corroded in place.
The most difficult part of the overflow reservoir replacement is removing the wiper arms and strut tower bar. The constant-tension hose clamps can be removed with pliers and the new hoses typically come with new clamps held in the open position to make installation of the hoses very easy. I found spraying silicone very SPARINGLY into the end of the hoses allows for easier installation. Remember to place the constant-tension clamps into the closed position before filling the system with coolant/distilled water.
There is a small plastic screw on the end of the upper hose to the metal line to allow you to bleed air out of the heater core when the vehicle is at operating temperature. Be sure to tighten the fitting when done and enjoy a cooling system without leaks and overheating issues!

Oh for Pete's sake. Don't go fooling around with mirrors and pressure tests. Your car is 11 years old now and the coolant tank has turned yellow and has developed cracks large enough to leak. Get a replacement from Nally. If you are really insistent on looking for the leak, you should just pull the tank since it's empty. Any way you slice it, good money is on replacing the tank just for being 11 years old.
