98 coolant reservoir question

My gf has a 98 taurus. She told me the other day that it was leaking coolant. She said it looked like it was coming from the bottom of the overflow reservoir. So I pulled the reservoir off and sure enough, its got a big crack in it on the bottom. So then I go online and try to find a replacement. All I find at parts stores are stainless steel tube shaped replacements(the original is plastic). I checked jcwhitney's, they have plastic ones, but the original has 3 ports, the one in jcwhitneys only has 2 ports. I think the stainless steel ones at autozone have only two ports also. I thought about going to a junkyard and pulling one off a wrecked car, but then I started thinking about the fact that I can't seem to find a store that carries replacement tanks. If there is some kind of problem with the tanks, as in they are bad about cracking, I'm hesitant to get one off a junker just to have it crack too. I need some guidance from someone in the know. If I replace the tank with a new one, what do I do with the 3rd hose? Why is it I can't seem to find an actual replacement part instead of the generic, one-size fits all types?
Any help would be appreciated.

What's the matter with getting an O.E. part from the parts dep't at a Ford dealership?

If you want a poor mans fix, get an old plastic milk container and cut a peice big enough to cover your break. Using a welder torch or heat gun, heat the plastic slowly and gently until it adhears to the plastic of the tank. I fixed several this way. I thought it would be a short range fix but, it lasted over 5 years.

I'll have to try that. Thanks for the tip.

Before you use the plastic from a milk carton you should know that the type plastic used now a days is biodegradeable and will deteriorate and crumble into a bunch of dry chips the size of Wheaties flakes in a few months. Sunlight and heat accelerate the process.

I tryed the patch, but i think the tank had gotten too brittle for it to stick. Tried a couple junk yards, they told me that they sell the tanks for taurus's faster than they can get new wrecks in. I ended up getting a tank from the dealer.

My heater was not working. It had not been working for about three years. Normally I did not care because I live in the Phoenix, Arizona area where you definitely do not need heaters but I was travelling up north. I had the shop unplug my heater core and they told me that the reason why my heater core was plugged was because my coolant reserovoir was leaking. This was on my 98 Ford Taurus SE. I knew I had a very slow leak because I had to put coolant in about every six months because it would go down. I just never bothered to fix it because I figured as long as I kept it filled since it was quite slow it would be okay. I went to a Ford dealership and bought a brand new reservoir for only $43.00. The salvage yard wanted $35.00 for a used one so I figure for eight bucks I might as well get the new one. It was quite simple to put on. It took me maybe 30 minutes to replace my old reservoir with the new one. The new OEM reservoir is not that expensive. You are better off just to buy the new one.
