Depends. What is the range of your thermostat? If you thermostat is a 190 then I would say you are running a little hot. If its a 205, then I'd say you are on point. Nothing wroung with running at that temp, just doesnt give you any wiggle room for sitting in traffic on a hot day.

Yeah it's the first time it's been that hot. Usually it runs around 190.

Well the one easy cheap thing to check and do is put a new thermostat in!

Check if your engine fan run in high and low speed. With the a/c off the fan turn on when the coolant reach 221* and stop once the temperature drops to 200*. Also the fan activate when the a/c is on. The setting that ford made imo is hot for ours cars.

I used in my car 160* thermostat, alluminum radiator, high flow water pump and the fan is set to turn on at 180* low speed and 190* high speed with the a/c off. I never had more problems.

+1 Use a high flow brand name aftermarket thermostat in the correct heat range for your car.

The factory temperature is for the best performance and efficiency.
The engine and cooling system were designed and built to run in that temperature range.
Any deviation from that range has adverse effects on the engine.
Running it to cold throws the ECU into cold loop mode and puts in too much fuel and to little timing advance which affects the performance and fuel efficiency.
It will also damage the engine over time because the mixture is too rich.

In a climate like I live where the temperatures reach 90* even in christmas the factory temperature is too high for me. Imagine two hours in a traffic jam every day going to work, trow to the trash the alluminum heads. The cooling problem is worse than a rich afr. In my case after many years with cooling problems and replaced almost every part related I decide to buy a chip and set the fan temps to my needs. Accordingly I set the spark borderline table and the afr.

You must have some other problem.
They are designed from the factory for temperature extremes in excess of that and most run just fine with no problems.


What are you saying about the aluminum heads?
They should actually help cooling because the aluminum will transfer/dissipate heat faster than the factory iron heads.

How hot? With a 195 degree T-stat they will get pretty warm.
You may need to flush the system, clean any debris from in front of the radiator and make sure the radiator fins are not smashed shut.

Re: Running to hot

That is right in Factory spec for your car. below 190* and I think the car stays in cold loop and will run worse If you are uncomfortable with it
pull the Stat and drill a few small holes in it. This will let a small amount
of coolant to flow even when it is closed. A what you buy isn't coolant
it is antifreeze. You can get some water wetter or something similiar
this increases the bond between the water and the radiator making it
more efficent. If you are in a hot climate just run WW & Water it will
cool way better and the WW has lubricant in it for the waterpump.

My 95' with H/C/I etc still has the factory radiator and ran hotter than I
was comfortable with when purchased. I bought a stant 10* stat, drilled
4-5 smal holes in it and now it stays at 195* 90% of the time..

You either have it professionally done or buy a kit from the auto parts store and do it yourself.

A lean condition or retarded timing can cause the engine to overheat.
Checking the timing is easy, but identifying a lean condition will require reading the plugs or the use of a wideband O2 sensor and meter. You can find info on plug reading in the sticky threads of this forum.

Note: Coolant is anything you use to cool your engine, usually a mixture of antifreeze and water, so saying antifreeze is coolant is actually a true statement. Also, not all water wetters have pump lubricant in them, but I have ran engines for years without ever using any type of pump lubricant, so whether it is actually useful or really needed is debatable. You are correct in saying water wetters increase the "bond" between the coolant and the metals though. What it does is reduce the surface tension of the water allowing a more complete and thorough connection between the metal surfaces of the engine, cooling system and coolant which results in increased heat transfer, thus better cooling ability.

I usually don't use any type of AntiFreeze, just water and some type
of Water Wetter, whether it be the actual product or one of another
name..

I can't get away with that here it gets to cold and I'd use the antifreeze anyways for the corrosion protection and additional cooling it provides even if I could.


P.S. A non-foaming detergent/soap will work as a water wetter too. That's actually what most detergents/soaps are anyways.
