Engine running hot?

Thanks - the local Ford Dealer told me they only work on cars 1996 and newer(something about standardized computers) so now what?

Talked to a dealer's mechanic - it took a while but they finally answered some questions. He said that as long as I didn't modify anything, the PCM should be fine. I have tested about everything I can and he said he is 99.9% sure it is the catalytic converters.

He says to replace both and it is just 6 bolts and a gasket - and to go with a direct fit that meets OEM specs and not a universal. I can get a Magnaflow direct fit for about $300.

Are these difficult to replace myself? Do I need any special instructions?

Ok. I'm in. I'll try it. I placed the order for a Walker direct fit because that is what the store told me is best and they could get it quickly.

I just bought jack stands and ramps and I am going to give it a go. Why, you ask, go through the effort when a shop would just lift it and get it done quickly?

Because I want to learn it. It is kind of fun. I learned a whole bunch about the engine - it is a cool engine. And people have been telling me how to modify it to get some serious horse power.

If the car didn't drive so good and I didn't need it to get back and forth everyday, I would consider doing some mods (like a high performance catalytic converter or a bigger MAF unit). However, when we get back on our feet, I will have a nice playtoy that my son and I can work on.

Because of this I have even found myself watching. I can't believe I am going to say this. NASCAR.

Hopefully, I can do this while lying on my back. If not, well the guy at the shop said bring it in and he would do it for labor and have it banged out in two hours or so. The part gets in tomorrow so I will let you know.

Thanks for the help and support and I will update on my quest to get my car fixed and the outcome.

1992 Ford Taurus 108, 00 miles

I have a 1992 Ford Taurus with a 3.0 L engine. When driving in traffic or idling in hot or cold weather the engine temp guage climbs well above it's normal position (just left of mid point). I have replaced the thermostat and the radiator cap. I've gone through 2 radiators. What is really strange is if the air conditioner is on, the engine starts cooling and runs at normal temperature. I have noticed that the fan activates and brings the temp down when it gets to the above normal position but does not return it to and keep it close to it's normal operating temp. Someone mentioned that when the cooling system gets air in it by removing the radiator cap it has to have the air bled off through a bleeder valve. Any ideas?
