03FocusZX3 Ty wntwn, sorry for the super late reply. I'll worry about it next summer :-P

whynotthinkwhynot It could be that crossover pipe too. I think it's around there somewhere, but I haven't owned a Zetec, so I don't know for sure.

Other elusive problems are any tiny leak from the cooling system, so be aware of any loss of coolant no matter how minor. Coolant systems must be sealed in order to function properly, otherwise you'll overheat quickly as well as boil over.

I'd chalk that one up to driving slow over very well heated asphalt not to mention the extra heat that running the AC causes in front of the radiator. It might have been just enough to tip you over the edge even with the fans running. Things get silly when temps get up over 100F.

03FocusZX3 Thanks whynothinkwhynot, i totally forgot about the odo trick, I have inspected the hoses, and they all seem fine, doesnt leak from where it was leaking when the car was overheating, had the radiator flushed when i installed a water pump. Hasnt overheated since that day, ive tested it, was sitting where i park, with the ac on, for atleast 15 min's and it never went past the middle on the temp. gauge. weird!

I'd closely inspect that hose, and if it wasn't all the way up on the radiator, then I'd loosen the clamp, loosen the hose and slide it up. I'd at least want to be sure there wasn't any small crack there in the hose. If there is, you'll have to replace it or at least cut that cracked part off and reconnect. Also, wait until the engine is warm sometime, then pop the hood and check out the hoses. Look for bloated spots in the hoses. If the hoses are swelling up, that's a sign that you'll soon be on the side of the road with a busted hose. You should have plenty of time to order new hoses and anything else you can think of from RA, then get some coolant (IDK if there's a HAZMAT charge to ship it), and do a good flush and replace hoses. FYI: If you're really froggy, remove the fans and radiator, then use water to flush the bugs out of the condenser. A typical cleaner like the purple stuff will loosen the bugs before you spray. That will help out your AC like you wouldn't believe. I'd also take the time to double check the fan resistor operation using the electronic odometer trick I described above to make sure you still have low speed. That's usually the cause of overheating while driving at low speeds or idling. At speeds over 30 or so, the fans don't do anything.

Where is Anniston? Near N. AL? My parents live in Elkmont. I'll be there this weekend.

It's better for you if you start your own thread. You might have similar problems, or problems that seem similar but point to other culprits through diagnosis.

First off, use the electronic odometer trick to see if your fans come on at 116C, which is I know is high, but from what we can tell that is the temp at which the fans come on low speed. High speed is not much further after that at about 118C. The AC turns the fans on high speed. It is possible that the resistor is out on your vehicle, and that keeps the fans from coming on low speed.

03FocusZX3 Oh ok, thank you AMC, i just dont know why it overheated that day, it was really hot outside...

amc49 Crawl up under the front and look at the front plate of the a/c clutch. If any of the 3 rubber shock absorbers are destroyed or gone, there is your noise. Common ailment. Ford used to carry that part alone for about $20 but I'd bet by cracky that they have 'unitized' it to make you buy the entire clutch for quite a bit more money.

03FocusZX3 True, if you guys think i dont take care of my focus, you are wrong, if it makes in sort of weird noise, i diagnose it, and fix it. I just dont know why this occured, anyone else? Ima look on rock auto and see how much a AC compressor is, because when i first turn it on that certain day, it makes a clunk/pop sound, and is quite loud imo.

amc49 For sure. If you didn't imagine the steam it WILL happen again. Up to you if the car is worth looking after. Be really dumb to torch a motor just because it didn't seem to happen again.

AC could be fine, the antifreeze that sprayed on it could easily make it sound funny until it burned off belt and clutch.
